Commercial Roofing Services

Commercial roofing services refers to  the expert and professional installation, repair, and maintenance of the roofs on commercial buildings. These services entail:

• Proper Installation of rooftops
• Thorough inspection of the commercial roofs
• Assessment for any issue that may arise
• Fixing roof leaks
• Replacing the roof looks when the need arises

Commercial roofing is an umbrella term for several types of roofing systems that roofers use on commercial buildings. These systems are:

• Slope roofs
• Built-up roofs (BUR)
• Metal roofs
• Flat roofs
• Thermoplastic olefin roofs
• Among many others

Roofing experts and contractors usually perform commercial roofing services because they have the necessary expertise and equipment needed to erect safe and efficient rooftops for commercial buildings. 

Commercial roofing services can sometimes also entail roof coatings, ventilation, and insulation. As a commercial property owner, you need to work with roofing professionals. It is because they have the expertise, experience and certification to ensure that your roofing system has structural integrity and longevity.

Residential and commercial roofing services have several similar characteristics. However, they have obvious and detailed differences. Let’s study some of these differences in depth.

Size and Complexity 

One major difference between residential and commercial roofing systems is their size and complexity. 

The roofing systems of commercial buildings are often larger and more complex than their residential counterparts. The result is that they require more materials, specialized equipment, and a higher level of expertise to install, maintain, and repair. 

Inspection

The time of inspection for a commercial roof is different from that of a residential roof. To maintain the integrity and longevity of a commercial roof system, the roof structure has to undergo frequent inspections. 

It is because regular inspections are vital for identifying potential issues in the early stages. The building owner can then address these issues earlier before they become larger and costlier problems. 

The people who typically perform these inspections are experts who have experience and knowledge about commercial roofing. They can identify potential problems and recommend the appropriate solutions to them. 

Unique Architectural Structures

Many commercial buildings have unique Architectural structures and features. Some of these features include rooftop decks, skylights, and mechanical equipment. 

Residential structures do not have these features. So the builder needs to have a higher level of specialization and experience to install these features on the roof.  

Load of the Roofing System

Another major disparity is the load and the usage of the roofing system. Commercial roofs are prone to heavier traffic and equipment. People also use them more frequently than residential ones. 

This can lead to more frequent repairs, and quick wear and tear if a roofer installs it like a residential roof. 

The Services Differ

Commercial roof services may include the following:

• Regular roof inspection
• Preventive maintenance
• Safety regulation
• Compliance with local building codes

All these are rare in residential roofing services. Both commercial and residential roof services may involve installation, maintenance, repair, and replacement. 

Still, the services of a commercial roof require a higher level of equipment, expertise, and skill for correct installation. 

Types of Commercial Roofing

There are several types of Commercial roofing. They include:

Flat Roof

A flat roof is a type of roof design where the surface of the roof is level with minimal slope. It is different from the sloping roof that has a noticeable incline. 

Flat roofs are most common in commercial and industrial buildings even though some residential properties have them. They offer usable larger space on the rooftop and they’re easier to access for maintenance. 

However, flat roofs need careful construction and design. It ensures water tightness as standing water can cause damage over time. 

Advantages of Flat Roofs for Commercial Buildings

Space Utilization

Flat roofs enable usable indoor and outdoor spaces by providing a level surface. A building owner can use this area for additional office space, a rooftop garden, or a recreational area.

Cost-effectiveness

It is generally less expensive to construct a flat roof in comparison to pitched roofs and other kinds of roofs. It is because they use readily available materials and installation is relatively quick. Flat roofs do not require costly materials such as rafters and trusses.

Easy Accessibility

Flat roofs are easier to access for inspection, maintenance, and repair.

Environmentally Friendliness

Flat roofs are useful for supporting rainwater harvesting, green roofs, and other sustainable practices that have to do with roofing.

Structural Flexibility

Flat roofs are one of the most flexible roofing kinds. They can easily adapt to the changing needs of a building. For instance, you may need to mount solar panels or additional space for extra rooms. 

Energy Efficiency

Flat roofs provide better insulation for buildings. It enhances energy efficiency and can reduce the cost of energy spent. 

Aesthetics

If you want your building to have a clean and modern look, flat roofs are one of your best choices. Flat roofs are clean and modern making them a popular choice for contemporary commercial buildings. 

Disadvantages of Flat Roofs for Commercial Buildings

Leakage

Constant water pooling on flat roofs make them more prone to leakage. As a result, there is water damage which affects the efficiency of the roof. With time, the roof will start leaking and lead to even more costly repairs.

Maintenance

As the owner of a commercial building, you’ll need to maintain the flat roof regularly. You’ll want to ensure that the roof is always free of debris and leaks. The roof will also require periodical application of a waterproof membrane. 

Weight Restrictions

Flat roofs have capacity limits when it comes to weight bearing. As a result, they are unable to support heavy equipment or machinery. It can even affect the space available on the rooftop. 

Short Lifespan

A flat roof has a considerably shorter lifespan than other types of roofs. In spite of frequently maintaining and repairing the roof, a flat roof does not last as long as a sloped roof. 

Built-up Roof (BUR)

A built-up roof (BUR) usually has multiple material layers. These layers often consist of multiple asphalt layers, insulation base, and a top gravel layer, or any roofing material. 

Often, builders may build these layers with hot asphalt and cover them with a protective membrane. BUR roofs prove useful for industrial and commercial buildings because of their durability and water resistance. 

Advantages of Built-up Roofing Systems for Commercial Buildings

Durability

BUR roofs are durable and have a long life span. It makes them a popular choice of builders when working on commercial buildings. 

Waterproofing

The several layers of asphalt in BUR roofs offer excellent systems for waterproofing. It helps to prevent water damage and leaks. 

Heat Resistance

The top gravel layer of the BUR roofing provides a tough level of insulation. It helps to reduce heat transfer while keeping the building cooler in the summer. 

Fire Resistance

BUR roofs are resistant to fire due to the inclusion of asphalt in the building process. It makes them one of the safest choices for commercial buildings. 

Versatility

A builder or building owner can customize BUR roofs to meet the specific needs and requirements of a building. It includes creating multiple layers, incorporating different materials, and adding insulation. 

Low Maintenance

BUR roofs require low maintenance in comparison to other types of flat roofs and roofing systems. It makes them a hassle-free and convenient option for building owners and managers. 

Disadvantages of BUR Roofing for Commercial Buildings

Heavy Weight

Built-Up Roofing (BUR) systems usually require multiple layers of materials. It makes them heavier. The result is that they require stronger structures to support their weight which can sometimes cost more.

High Installation Cost

Installing BUR roofing systems can be labor-intensive. It often requires specialized equipment, which can increase installation costs.

Long Installation Time

The time that a roofing professional needs to install a BUR roofing system can be significantly longer. It can result in business downtime for industrial and commercial buildings. 

Complex Maintenance

BUR roofing systems require regular inspection, maintenance, and repairs. It can be costly and time-consuming.

Vulnerability to UV Radiation

BUR roofing systems are vulnerable to UV radiation and can make the asphalt break down over time. The result can be leaks, costly frequent repairs, and time-consuming maintenance. 

Modified Bitumen Roofing

Modified bitumen roofing is a kind of roofing system that builders use on industrial and commercial buildings. 

The general composition of modified bitumen roofing is asphalt and rubber-like materials (typically SBS or APP). These materials usually undergo modification to enhance their durability, performance, and weather resistance. 

The modified bitumen sheets then undergo heating before the roofing professionals roll them onto the roof. On the roof, the builders seal the sheets together to create a continuous waterproof membrane. The system can be either self-adhered or torch-applied.

Often, builders combine the sheets with insulation and other vital roofing components to create a complete roofing system. 

Modified bitumen roofing offers a long-lasting, and durable roofing solution for commercial and industrial buildings. But this type of roofing can be more expensive to install than other roofing types.

Advantages of Modified Bitumen Roofing for Commercial Buildings

It Ensures Roofing Quality

Modified bitumen sheets assure roofing quality. They often come with a granular surface layer with a mineral surfacing procedure. Both the granular and the mineral procedure happens in the factory to guarantee consistent application. 

In addition, modified bitumen roofing does not easily wear out and minimizes the costs of repair over time. 

Makes Installation a Breeze

It is important to consider safety when applying a torch or open flame during bitumen installation. However, bitumen systems do not require many complications. 

The result is that you can save money on labor and experience less disruption. 

Prevents Intrusion of Water

Modified bitumen roof comes in overlapping rolls and comprises large seamless areas. Fewer seams mean lesser chances of leakage. 

If you use modified bitumen as a roofing option, you can rest assured that there’s no fear of leaks. 

Can Resist Strong Winds

Roofing experts usually attach the base sheet of the bitumen material to the cap nails. Sometimes, a builder may prefer to use disc plating. The result is that it can resist wind effectively without pulling off. 

Structural Soundness at Low Temperatures

Modified bitumen systems come with roof wear lowers that have polymer reinforcement. It enables the roof to perform well in cold climates. 

They’re also elastic and flexible and can stay in one piece even in freezing weather conditions. 

Reduces Construction Waste

Mod bitumen roofs are recyclable. Although they are not hundred percent green just like other conservable roofing systems. But they are durable and sustainable and one of the friendliest roofing systems in nature. 

Disadvantages of Modified Bitumen Roofing for Commercial Buildings

Can Be Hazardous

Modified bitumen roofing systems are potential fire hazards. The style of this roofing system involves heating which is dangerous because most buildings have wooden components near the roof. 

Although there are cold adhesives, self-adhering modified bitumen. But the heating application is still the most prevalent on the market. 

Absorbs Heat in Summer Periods

One major disadvantage of modified bitumen roofing is that it is heat-absorbent in winter periods.

The color of a modified bitumen roofing membrane is mostly black. So it only minimally reflects heat. The dark color of the rooftop attracts and absorbs heat from the sun instead of reflecting it away from the building.

More Vulnerable to Ponding

Buildings with roofs that tend to hold melting snow or water all become worn sooner when builders install a modified bitumen roofing system. 

Standing water and puddles that develop after rain storms can cause serious damage to the roofing. It will prematurely age a modified bitumen roofing system if there is no proper drainage.  

Modified bitumen seams and plies are very vulnerable and do not handle standing water well.

Modified Bitumen Can Be More Expensive

Re-covering an existing modified bitumen roof with a single-ply modified bitumen cap sheet is cost-effective. But installing more than one ply will drive up costs.  

Also, multi-ply modified bitumen systems significantly cost more when installed on large roofs.

Thermoplastic Polyolefin Roofing

This type of roofing is a combination of several single-ply roof membranes with ethylene-propylene rubber designs. These membranes supposedly combine the exceptional performance of the hot-air sealable closures with the sturdiness of EPDM rubber.

TPO membranes are reliable roofing materials with good resistance to ozone.

TPO roofing is also friendly to the environment and resistant to algae. Another reason why builders prefer this roofing system for commercial buildings is that they are easy and safe to install.

Advantages of Thermoplastic Polyolefin Roofing for Commercial Buildings

Cost-effectiveness

One major reason that property developers prefer thermoplastic polyolefin roofing over other options is their affordability. 

In addition, thermoplastic polyolefin offers PVC roofing benefits. It includes hot-air sealable seams and an increment in energy efficiency all at lower costs.

Matches Different Architectural Styles

The designs of thermoplastic polyolefin roofing membranes match different architectural styles. Moreover, they are available in several colors including black, white, and gray, among others.

These colors are highly reflective and help in reducing energy costs. Builders also construct TPO membranes using the latest technologies. It enables them to resist harmful UV rays.

They Are Resistant to Dirt and Cracks

Thermoplastic polyolefin roofing membranes can resist mold growth, punctures, dirt accumulation, and impact. They are flexible and allow the settling of a building. 

Also, if builders reinforce the membranes of your thermoplastic polyolefin roofing, they can withstand your building’s thermal contraction and expansion to avoid cracks.

Ease of Installation

The sheets of thermoplastic polyolefin roofing membranes are lightweight. As a result, it is easier and less costly to install them.

Energy Efficiency

If you need a roofing option that enhances your savings on your air conditioning costs, thermoplastic polyolefin roofing is a good choice. Their reflective surfaces reduce the permeation of heat into the building so you can cool less. 

Disadvantages of Thermoplastic polyolefin Roofing for Commercial Buildings

The Membrane Is Easily Puncturable

One major disadvantage of thermoplastic polyolefin roofing is that the membrane is easily puncturable. 

With commercial buildings, there’s a higher tendency of more footing traffic in comparison to residential buildings. The single-ply membrane of thermoplastic polyolefins does not have a top layer. So the layer of the synthetic rubber does not have adequate protection from dropped tools, loose screws, or gravel among other things. 

When items like this drop, they often push into the rubber membrane of the TPO. It breaks or tears into it creating holes in the insulation and rubber. The result is that the roof is more vulnerable to leaks with time. 

UV Rays Can Degrade the Adhesives

Wear and tear is another common thermoplastic polyolefin roofing problem. It is because of its never-ending exposure to the weather and other natural elements including the sun.

Upon constant exposure to sunlight, harmful UV rays can significantly damage TPO over time. It can occur in several ways. But the most common issue is when the UV rays degrade the adhesives that attach the membrane to the substrate.

Apart from that, those adhesives seal the seams of the membranes together. It is this adhesive that creates the waterproof seal keeping your roof safe even in the harshest of weather conditions. Without the seal, your roof becomes vulnerable.

Ethylene Propylene Diene Terpolymer (EPDM)

EPDM is an extremely durable synthetic rubber roofing membrane that commercial low-slope buildings popularly use. It has two main ingredients, ethylene, and propylene. These ingredients are derivatives of oil and natural gas. 

EPDM is available in black and white. It has a variety of widths, ranging from about 7.5 feet to 50 feet. The thickness of EPDM is in two dimensions, 45 and 60 mils. 

Roofers can install EPDM either with full adhesion or mechanical attachment and ballasting. Then they seal the seams of the roofing system with specially formulated tape or liquid adhesive.

Advantages of EPDM Roofing Membrane for Commercial Buildings

It Lasts Long

EPDM roofing consists of durable materials that provide high-quality performance for a very long time. The roofing is suitable for roofs that are flat and have low slopes. 

EPDM roofing is also great at preventing water from penetrating the building. It also prevents leaks. As a result, it is a popular choice for property owners looking to waterproof their roofs.

If you’re planning for green roofs, roof extensions, garages, or dormer roofs with either a cold or warm deck design, EPDM is a viable choice. Changing weather also doesn’t affect its resilient material.

 In fact, EPDM will remain flexible on the coldest days, which means that it won’t crack or shatter. Unlike other types of roofing materials, EPDM will maintain its integrity and not deteriorate over time.

It Is Eco-friendly

If you’re looking for green roofing options, EPDM is the way to go. It is one of the best ways to desist from petroleum-based roofing. 

EPDM generally uses recycled products in its manufacturing process. Its white color also reflects sunlight and helps in reducing your building’s energy consumption. 

In addition, EPDM roofing is compatible with rooftop gardens. It enables air quality improvement and further reduces the temperature within the building. 

Moreover, roofers can recycle EPDM and reuse it as a new material when it reaches the end of its lifespan.

Installation Is Simple

EPDM roofing is exceptionally easy to install. It needs very few seams and they are easy to apply. As a result, EPDM is one of the most suitable types of re-roofing materials for buildings that people already occupy. 

The simplicity of laying down this type of roofing enables the installation of a new flat roof with minimal disruption to your daily schedule. 

The easy and foolproof application of EPDM ensures that you achieve a superior membrane without compromising on longevity. 

Some EPDM roofs are also tough enough to walk on, allowing roofers to reach and perfect every square inch.

Ease of Maintenance

EPDM hardly requires any maintenance after installation. The waterproof membranes are permanently flexible and can last as long as the material itself. 

EPDM also takes a long time to age so the roof is always as good as new.

Disadvantages of EPDM Roofing Membrane for Commercial Buildings

Easy to Damage

Although EPDM roofing offers adequate protection in many circumstances, it is still vulnerable to damage. Rubber roofing often consists of one thin layer of material that has constant exposure to the elements. 

Debris from a storm or even someone walking on the roof wearing the wrong footwear can easily damage the roof. 

Prone to Shrinkage

With time, continuous exposure to the elements can shrink an EPDM roof. It can lead to leakages when the seams start to come apart and the cracks open up. 

Although roofers try to prevent this by coating the EPDM roof with acrylic paint, this may still pose a problem, especially in dry climates. 

An EPDM roof can begin to crack because of shrinkage in 7 years if roofers poorly install the roof. Leaks can also be hard to detect until they become very evident within the building, an indicator that there is already damage.

Roof Protrusions

Roof protrusions like vents, HVAC units, pipes, and more cause natural vulnerabilities for your roof. Unless you’re a professional who does inspections very frequently, protrusions can be hard to detect. 

Roof protrusions may also compromise the integrity of your EPDM roof, making you want to replace it early.

Metal Roofing System for Commercial Buildings

A metal roofing system is a type of roof that stems from tiles, panels, or metal pieces. It is part of the roofing envelope that physically separates the inside and outside of a commercial building.

A metal roofing system can provide resistance to air, sound, water, and heat. It also contributes to the structural support and overall aesthetic appearance of a building.

Advantages of Metal Roofing System for Commercial Buildings

High Durability

Metal roofing is a combination of different kinds of alloys that provide tough tensile strength. It means that a metal roof can bear heavy weights. It can also withstand extreme temperatures without breaking or deforming. Metal roofing is ideal for industrial and commercial buildings in areas that experience sweltering summers and freezing winters.

In addition, metal roofs offer exceptional fire resistance. If your commercial building is in an area that’s prone to wildfires, metal roofing can help you protect your property and minimize damage. 

Sustainability

Metal roofing for commercial buildings offers energy efficiency benefits. It makes it a sustainable material. Sustainable metal roofs are often products of reclaimed or recycled materials. 

Metal roofing also reduces waste footprint as it is completely recyclable. 

Furthermore, metal roofs in light colors reflect sunlight. It reduces the amount of heat that commercial buildings absorb. In turn, you can lower your cooling and heating expenses.

Long Life Span

In addition to its durability, metal roofing has a long lifespan. Traditional asphalt roofing materials can last about ten to twenty years. The average lifespan of a metal roof is between forty to seventy years. 

Also, metal roofs require minimal maintenance.  Although necessary, the check-ups are less frequent in comparison to the requirements of other roof kinds.

Aesthetics

You can customize metal roofs according to the style, color, and design that you want. Metal roofing sheets come in several colors that you can choose from. It also mimics traditional roofing materials like shingles or slates if you want a classic look while still maintaining durability and longevity.

Disadvantages of Metal Roofing System for Commercial Buildings

It’s More Difficult to Repair

The first con of a metal roof is that it is harder to repair. Metal roofs are durable but several things can occur.

For instance, rusting from damage to the painted finish, or damage from storms. When this happens, it takes experience and more expertise to repair a metal roof than some other roof types.

It also means more expenses due to the difficulty it needs to do the job right. 

Possibility of Oil Canning

Oil canning happens when roofers fasten the metal panels too tightly during installation. If this happens, the metal roofing can expand longways but not sideways. 

With time, the metal roof will show signs of oil canning. While this doesn’t affect its functionality, it can cause an aesthetic issue. 

It Can Be Very Noisy

If roofers install a metal roof over solid decking, your ceiling helps absorb some of the noise. You can add wood fiber insulation boards between your metal panels and roof deckings also to help with the noise. These boards will help to absorb sound, but only to an extent.

However, a metal roof will still make some noise especially when it rains. Even with insulation boards, it’s impossible to completely drown heavy sounds.

It Is Expensive

One of the biggest disadvantages of Metal roofs is the cost. For instance, a two-story building with a metal roof will cost around $15.00 per square foot.  

The good part, however, is that it is long-lasting. So even the expense is an investment for many years. 

What Is the List Of Commercial Roofing Services?

The list of commercial roofing services typically includes:

• Roof installation and replacement
• Roof repair and maintenance
• Leak detection and repair
• Roof coating and waterproofing
• Insulation installation and replacement
• Skylight installation and repair
• Snow and ice removal
• Emergency repair services
• Energy-efficient roofing solutions

Roof Installation and Replacement

A commercial roofer needs exceptional expertise and skill to install and replace the roof on an industrial or commercial building. It is a step by step process to make sure that roofers install the new roof the right way. The roof will then offer durable protection and longevity for industrial and commercial buildings. 

Here is an in-depth explanation of the roof installation and replacement process:

Roof Preparation

Before roofers install a new roof, they must properly inspect the existing roof structure. It includes inspecting for any damage to the support structures like warping or rotting. 

If the roofers find any damage, they must repair or replace it before they install the new roofing material. After which they remove the old roofing material, and clear the decking of any debris.

Installation of a Waterproof Underlayment

The roofing contractor installs a waterproof underlayment between the new roofing material and the decking. It is to prevent water from entering the building. 

The underlayment constitutes a synthetic material that offers a barrier against water and wind. Roofers install the underlayment sections, ensuring that each piece overlaps the previous one to create a continuous barrier.

Installation of Flashing

Flashing is a rubber or metal material that roofers use to prevent water from leaking into the building at the roof penetration or meeting points. For instance, roofers install flashing around chimneys, roof vents, and skylights to prevent water from seeping into the building. 

They install the flashing in sections, with each piece overlapping the previous one to create a watertight barrier.

Installation of the New Roofing Material

The roofers install the new roofing material in a specific pattern. Each piece overlaps the previous one to create a watertight barrier. The roofing material is mostly a product of asphalt shingles, rubber membranes, or metal panels. 

The specific method and pattern of installation depend on the roof’s slope. The type of roofing material that the roofers’ use is also important.

Final inspection

Upon installation of the new roofing material, the roofers conduct a final inspection of the roof to ensure that there is proper installation and water tightness. 

The inspector will check for any form of improper installation such as leaks and flashing. They’ll also inspect for any damage to the roofing material. If they find any issues, they must correct them before they consider the inspection complete.

Leak Detection and Repair

Leak detection and repair in commercial buildings is a vital part of every commercial building’s maintenance. It helps to ensure that the building systems are functioning effectively. It also prevents damage to the building. 

A leak in the roof of a commercial building can result in waste and costly repairs if the owner doesn’t address it on time. 

Leak detection and repair involves:

Inspection

This is the first step in detecting and repairing any roof leak. Inspectors visually check the roof for any signs of leaks. If they suspect any leak, they further conduct tests to confirm its presence.

Testing

After the initial inspection, the inspectors use non-destructive testing methods to confirm the presence of a leak. Examples include the use of infrared imaging to check for moisture buildup behind walls and ceilings. Inspectors can also use water testing to check for water entry into the building. 

Testing helps the roofing inspector to narrow down the leak’s location and determine the level of the problem.

Repair

Once the inspector confirms the source of the leak, they can repair it. Repairs may include fixing or replacing bad roofing materials. Sealing seams and joints and installing flashing are also instances of roof repairs.

If a bad roof penetration is causing the leak, they may need to reseal or replace that area. The repair aims to stop the leak and prevent water damage to the building.

Maintenance

Regular roof maintenance is vital to prevent future leaks. Often, this entails checking for signs of wear or damage. It is also essential to repair any minor issues before they become major problems. 

Scheduling regular roof inspections will enable you to identify any potential issues before they turn into large leaks and costly repairs.

Roof Coating and Waterproofing

Generally, the major purpose of commercial roof coatings is to increase the efficiency of your commercial roof and its longevity. Roofers can apply roof coatings by spraying or roll-applying directly to the existing roof surface. 

The roof coating shields your commercial building from leaks because of its:

• Monolithic structure (meaning that it lacks seams).
• Self-adhering property (meaning that it doesn’t need any fasteners).
• Fashing ability (meaning that it has just one membrane)
• Reflective property (meaning that they do not absorb ultraviolet rays but instead reflect them back into the atmosphere)

Additionally, roof coatings keep your commercial roof surface and the interior of your building cooler, helping you spend less.

Waterproofing
Waterproofing commercial roofs create watertight ice, snow, and rain protection that can help you avoid the negative effects of water seepage.

Various issues like humidity and ultraviolet light often cause leaks in commercial roofing systems. It can get worse during the summer periods and the extreme snow, cold, and ice of winter periods.

A roofer can waterproof most low-slope roofs and roofing materials. But they may need varying solutions. It is why it is best to work with an expert roofer who understands how to seal a commercial roof and the climate of the area.

Your roofer can choose to use a rubber roof waterproof membrane. Sometimes, they may decide on a roof sealant that protects the foundations walls. What is most important is that your solution addresses your specific type of roof.

Installation and Replacement 

Insulation is a vital component of a commercial building roofing system that enhances the maintenance of a stable indoor temperature, reduces energy costs and prolongs the lifespan of the roofing system. 

The process of insulation installation and replacement of commercial roofing :

Removal of the Old Insulation

The first step is to get rid of the old insulation material. Roofers can do this by cutting the old insulation material into sections and pulling it out. They can also use an insulation removal machine. They’ll remove and replace any worn roof decking as well.

Surface Preparation

After removing the old insulation, the roofers will thoroughly clean the roof deck surface. They’ll address any moisture or mold issues at this stage. If not, these can damage the new insulation material and affect the performance of the roofing system.

New Insulation Installation

The roofers will install a new insulation material made up of cellulose, fiberglass, and foam between the roof deck and the roofing membrane. 

You must ensure that the roofers securely fasten the new insulation in place. The insulation must also be able to withstand rain, wind, snow, and other environmental factors.

Sealing the Seams

The seams between the insulation panels can cause  moisture and air infiltration. 

To avoid this, the roofers seal the seams with a special sealant or tape. It maintains the integrity of the insulation and prevents energy loss.

Installing the Roofing Membrane

After installing that insulation and sealing the seams, the roofers install the roofing membrane over the insulation. 

The roofing membrane is typically a composition of waterproof material. It can be rubber, asphalt, or synthetic material. 

Roofers should ensure that they install roofing membranes correctly. It needs to offer a weather-tight seal and also prevent water from seeping into the building.

Ventilation

Proper ventilation is vital in commercial roofing systems. It prevents moisture buildup and elongates the lifespan of the roofing system. 

Ventilation may involve installing ridge vents, roof vents, or other ventilation systems. What majorly determines this is the building’s climate and the roof design.

Skylight Installation and Repair

Skylight installation and repair entail several steps. Let’s study each one differently.

Skylight Installation

Below are the steps for skylight installation in commercial roofing systems.

Site Evaluation

First, the roofer has to determine the best location and size for the skylight. It involves inspecting and evaluating the building’s orientation and the roof slope. The evaluation will affect the skylight’s performance.

Roof Preparation

Once the location is determined, the roofer will need to prepare the roof for the skylight installation. Preparation may include putting a hole in the roof deck to accommodate the skylight or installing a frame. Roofers also need to ensure that the roof surface is smooth and level.

Skylight Installation

At this point, the roofers place the skylight unit into the opening in the roof deck and secure it in place. It is crucial that they properly seal the unit to prevent leaks and water damage.

Flashing Installation

Next, the roofing professional install the flashing around the skylight’s perimeter to direct water away from the building. They should ensure that they install the flashing in such a way that it overlaps the roofing material. 

 

The roofers should also extend the flashing down the sides of the skylight to prevent water from getting into the building.

Ventilation

Some skylights have built-in ventilation features so that hot air can escape and fresh air can enter the building. 

In this case, the roofers will need to connect it to the electrical system.

Finishing Touches

This is the final step. Here, the roofers perform any necessary finishing touches

It may be painting or staining the frame to match the roof.

Skylight Repair

Below are the steps for skylight repair in commercial roofing systems.

Inspection

The first stage in skylight repair is inspection. It helps roofers to determine the cause of the problem. 

Inspection may involve looking for gaps or cracks in the skylight or checking the flashing for leaks. Roofers also look for any signs of water damage around the skylight.

Cleaning

Roofers must clean the skylight and surrounding roof area before making any repairs. It helps them ensure that the repair materials will properly bond.

Repairing Seals and Flashing

If there is a leak, the roofers will first repair any damaged seals or flashing. It may involve the application of a new layer of sealant. They may also replace bad flashing or install new flashing to direct water away from the building.

Replacing the Skylight

Sometimes, the best solution may be to replace the entire skylight unit. It is even more necessary if the skylight is severely bad or if it is not performing well due to any reason at all.

Snow and Ice Removal

Removing snow and ice from commercial building roofing systems is a vital aspect of maintaining and safeguarding commercial buildings. 

The buildup of snow and ice on the roof can cause damage to the roofing material, and structure. It can also pose a risk to the building occupants. 

Let’s look at the key steps that snow and ice removal entails:

Monitoring

Regularly monitoring the roof and its surrounding area is necessary to detect any buildup signs of snow and ice. You can achieve this through visual inspections, sensors, or other building monitoring systems.

Prevention

To minimize snow and ice buildup, commercial building owners can take steps such as:

• Improving insulation and ventilation in the attic
• Using heat cables and roof-mounted heaters
• Designing the roof to promote drainage.

Shoveling

One common method of snow and ice removal is shoveling. Roofers can use either shovels or other specialized tools. 

Shoveling is a suitable method for commercial buildings with low-sloped roofs and a low accumulation of snow. 

Melting

De-icing agents are helpful in areas with low snowfall. Building owners can use salt, calcium chloride, or potassium acetate to melt snow and ice. They can apply these agents by hand or by using a spreading machine.

Drainage

Roofers should ensure that snow and ice melt water can drain off the roof and away from the building structure. 

Usually, this requires a functioning drainage system. It includes downspouts, gutters, and other components.

Maintenance

Regularly maintaining the downspouts, roof, gutters, and other drainage systems is crucial. It ensures that they are functioning well and there are no blockages. 

Maintenance can help prevent water damage and reduce the need for ice and snow removal.

Emergency Repair Services

Emergency roof repair services are also on the list of services for commercial roofing.   

There can be a sudden roof failure or damage due to severe weather conditions or any unexpected events. 

These services enhance quick, efficient, and effective repairs. It helps to minimize roof damage and restore its functionality. 

Some major elements of emergency roof repair services in commercial building roofing systems include:

Rapid Response

Anything that is an emergency demands a rapid response. If there is a sudden roof failure or damage, time becomes crucial. 

The repair team should be able to respond quickly to requests so that they can minimize the damage. It will also enable them to prevent further issues from arising. 

Assessment and Diagnosis

The repair team will carry out a thorough assessment of the damage. They will inspect the roof and diagnose the cause of the problem. 

They must undergo this step to determine the most efficient solution to the issue. Accurate diagnosis enables the prevention of future problems. It also ensures that the roofers perform the repair properly.

Temporary Repairs

Roofers can perform temporary repairs to prevent further damage until they can find a permanent solution. 

Often, these may be covering the bad areas with tarps. They may also install temporary supports. 

Temporary repairs are vital in ensuring that the roofing still performs well until there is room for a permanent repair.

Permanent Repairs

Roofers should carry out permanent repairs with high-quality materials. Using industry-standard techniques will also ensure the longevity of the repair.   

The roofing repair team should have the necessary experience and expertise for effective and efficient repairs.

They should also carry out permanent repairs on time to prevent further damage and restore the roof’s functionality.

Removing the flashing should be a last resort, as removing the flashing can impose more damage if the roofer removes it improperly.

Are There Different Quality Types for Roof Flashing? How to Know Which Roof Flashing Quality to Install?

There are several types of roof flashing. The quality of flashing varies according to the materials that the roofers use. The manufacturing process is also a factor. 

Here are some types of roof flashing and how to know which type to use:

Aluminum Flashing

Aluminum flashing is a popular choice because it is:

• Lightweight and corrosion-resistant
• Ideal for coastal, commercial, and industrial areas
• Very affordable in comparison with other materials.

Copper Flashing

Copper flashing is one of the most premium options for roof installers because it is:

• High durable and long-lasting
• Resistant to oxidation and corrosion
• However, copper flashing is expensive in comparison with other materials

Galvanized Steel Flashing

Galvanized steel flashing is another popular choice for roofers and commercial building owners because it is:

• Affordable and common
• Has zinc layers coating to prevent rust

However, galvanized steel flashing is not as durable as other materials.

Stainless Steel Flashing

This is a very high-end option. Stainless steel flashing is:

• Durable and rust-resistant
• Ideal for harsh conditions environments

Stainless steel flashing is the most expensive compared to other materials.

The type of flashing that a roofer will install on a commercial building will depend on:

Roof

The roof’s type and pitch can impact the type of flashing that roofers can use. Certain flashings suit low-slope roofs best, while others are better for steep roofs

Climate

The climate and weather conditions of an area will affect the durability and longevity of the flashing.

Areas or environments with high winds, high humidity, or heavy rainfall may require a more durable material

Building Codes

Building codes specify the barest standards for roof flashing in an area.

It’s vital to follow these guidelines to ensure safety and compliance

Budget

The cost of the flashing material affects the type of flashing. A more expensive material may be necessary for harsh conditions, but a building owner cannot use it if it doesn’t fit into the budget.

The Longevity and Durability of the Flashing Type

Copper or stainless steel flashing, for instance, is best for coastal areas with salt air because it can resist corrosion. 

However, aluminum flashing is the best option for areas with extreme ultraviolet rays and high temperatures. It is because aluminum is resistant to warping and cracking.

Note:

You should understand that the quality of the installation is also important. Irrespective of quality, a roof flashing will only perform well if the roofer installs it correctly. 

Therefore, you should only hire a reputable and expert roofing contractor. They can recommend the best flashing options and ensure that they properly install the flashing.

What Environmental Factors Affect the Quality of Flashing to Use? How to Know Which Roof Flashing Is Best to Use?

Some environmental factors can also affect the quality of flashing that roofers use. These factors include:

• Exposure to chemical pollutants that can cause corrosion. An example is salt air.

• Exposure to high winds, heavy precipitation, and other severe weather conditions. It can make the roof’s flashing wear out more quickly.

• Exposure to ultraviolet rays and extreme temperatures. These can cause cracking, warping, or discoloration of the flashing.

• The presence of acidic precipitation. Examples are acid rain. It causes metal flashing to corrode.

What Can the Contractor Conclude When the Roof Surface Has Missing or Damaged Tiles or If the Surface Is Uneven?

If the roof surface is missing or it has damaged or uneven tiles, it is often an indication that the roof needs repair or replacement. 

The contractor should first assess the extent of the damage and recommend how to fix the issue. It may involve replacing the damaged or missing tiles, replacing or repairing the underlayment, or re-sloping the roof to make it even. 

The roofing contractor should also consider if there are any underlying structural issues. It may be the cause of the damage. The contractor will also recommend how to address those as well.

Also, roofing surfaces that have missing or uneven tiles can indicate wear and tear. It often means that the roof is nearing the end of its lifespan and may need replacement. 

Some other probable conclusions that the roofing contractor can make include the following:

Widespread Damage

If the damage is widespread, or if there are several areas of missing tiles, it may mean the roof is already reaching the end of its lifespan and needs urgent replacement. 

Tile Isolation

If the missing tiles are in isolation, the roofing contractor can decipher that the damage is a result of a specific event. Examples are storms or heavy rainfall. 

The contractor can recommend the repair or replacement of missing areas. 

Uneven Roof Surface

An uneven Roof Surface may mean that the roof deck or framing has structural issues. It often leads to leaks and water damage. 

The roofing contractor will need to address these structural issues before they repair or replace any of the tiles. 

Wear and Tear

If the missing or bad tiles are a result of wear and tear, it is an indicator the roof is nearing the end of its lifespan. The contractor will advise the owner of the building to replace the roof as soon as they can. 

Roof Reassessment

The contractor should reassess the roof surface for any bad or missing tiles. The reassessment is a vital step for understanding the roofing condition and identifying any potential issues that need readdressing.

Missing tiles can lead to leaks and an uneven surface can mean that the roof deck has structural problems. If the contractor finds any of these issues, they should take the appropriate measures. It will prevent worse issues like water infiltration and structural problems that may occur in the commercial building. 

Solution and Recommendations

It is vital for the contractor to provide solutions and recommendations to the owner of the commercial building. Both the contractor and the building owner need to work together to address the issues that the contractor discovers. 

It is best to address these issues on time to prevent mold growth, infiltration, and structural damage. Regular inspection and maintenance are also important for the roof to stay in good condition. 

Other crucial things that the contractor can check include:

The Flashing

The roof contractor or repair team should inspect the flashing around chimneys, vents, and other roof protrusions. They need to ensure that the flashing is securely fastened and not leaking.

The Gutters and Downspouts

The roofing contractor should inspect the gutters and downspouts for any leaks or clogs. It is important to ensure that water flows well through the downspouts and the gutters. 

The Ventilation

The roofing contractor needs to check the roof’s ventilation to ensure that there is a proper flow of air. It also prevents mold growth and moisture buildup in the attic. 

Visible Obstructions, Such As Tree Branches or Debris, Could Damage the Roof or Impede Proper Drainage. Which Obstructions Are Not So Visible That They Can Affect the roof? How do they affect the Rooftop?

Several factors can affect the health and longevity of a roof. It includes both obvious and hidden obstructions. 

These obstructions can include the following:

• Clogged gutters and downspouts
• Ice dams
• Poor ventilation
• Debris on the roof
• A vent pipe and flashing issues 
• Insufficient insulation

Clogged Gutters and Downspouts

Gutters and downspouts play an essential role in directing the flow of rainwater away from the foundation and the roof. If the gutter or downspouts clog up with debris like sticks, leaves, or other materials, water can build up, causing leaks or water damage. 

In addition, gutters that clog up can lead to improper drainage, making water back up into the roof or pool near the foundation, and causing further damage. 

Ice Dams

Ice dams are another common problem in colder climates. Sometimes, snow on the roof melts and freezes again beside the eaves, forming a dam-like structure. 

It then causes water to back up, leading to leaks and water damage. Further, the weight of snow and ice can structurally damage the roof and gutters.

Poor Ventilation

Ventilation is a vital aspect of roofing systems. It helps in regulating the moisture and temperature levels inside the attic space. 

Improper ventilation can cause problems like rotting, mold growth, and decreased energy efficiency. It can also cause ice dams to form more easily in winter months.

Debris on the Roof

Debris like sticks, fallen leaves, and other materials on the roof can lead to clogging up gutters and poor drainage. 

Moreover, heavy debris can physically damage the roof or prevent ventilation, causing further problems.

A Vent Pipe and Flashing Issues

Vent pipes and flashing direct rainwater and other elements away from the roof. 

When the vent pipes or flashing has issues, like cracks or missing sections, leaks, and water damage can occur. They can also affect the structural integrity of the roof.

Insufficient Insulation

Insufficient insulation can affect the roof in several ways. It includes mold growth, energy increment costs, and reduction in energy efficiency. It can also lead to condensation problems, leaks, and water damage.

Regular roof inspections and maintenance can help the commercial building owner to identify and prevent these issues. It also ensures that the roof remains in good condition and protects the building from damage.

What Steps Will the Contractor Take To Check the Roofing System’s Energy Efficiency and If The Building Can Benefit From Cool Roofs, Reflective Coatings, or Insulation Upgrades?

A building contractor or professional should:

Thoroughly inspect the condition of the current roofing system. They should check the age, conditions, and type of roofing materials. 

Assess the roof for any form of damage, leaks, or areas where the insulation seems inadequate.

Properly and accurately measure the thermal emittance and solar reflectance of the current roof surface. These often determine the energy efficiency of the roof.

Assess the building’s energy usage and see if the commercial building has an opportunity for energy savings. It includes the use of reflective coatings, cool roofs, or insulation upgrades. 

Consult with other professionals in the commercial roofing field. Examples are roofing experts and energy consultants. It will help the contractor to know the best line of action.  

Map a plan for the implementation of the possible upgrades. It includes cost estimation and a completion timeline.

Carry out all necessary functions. It includes adding insulation, replacing the roof, and choosing an option that is more energy efficient or installing reflective coatings. 

Monitor the building’s energy consumption after making the upgrades to ensure that they provide the appropriate energy savings level for the building. 

How Do Professional Roofers Measure the Solar Reflectance and Thermal Emittance of the Existing Roof Surface? What Are the Adequate Measurements?

A commercial roof’s energy efficiency is a vital aspect that affects the total energy performance of a building. 

Energy-efficient roofs can reduce energy costs and create a more sustainable environment. Roofing professionals determine the energy efficiency of a commercial roof by two major factors. They are:

• Solar reflectance 
• Thermal emittance

Solar Reflectance

Solar reflectance is the percentage of solar radiation that the roof surface reflects. Roofers measure solar reflectance with a portable reflectometer. It indicates how well the roof may perform when reflecting and reducing the amount of heat that enters the building. 

You should measure solar reflectance at different angles due to the sun’s changing position. Also, test three points on the roof to be sure of accurate results. A solar reflectance with over 70% value is ideal. It reduces both heat and the need for air conditioning systems. 

Thermal Emittance

Thermal emittance is the commercial roof’s ability to give off heat. Roofing experts can measure thermal emittance using infrared thermography. It is an indicator of how well the roof will dissipate heat that the building generates within.

A thermal emittance with more than 70% value is preferable as it dissipates the heat that the commercial building generates inside. Thus, it reduces the need for air conditioning.

Apart from solar reflectance and thermal emittance, other factors that can affect a roof’s energy efficiency are:

• Insulation R-value
• Airtightness
• Ventilation.

Insulation R-value: It shows the resistance of the insulation material to heat flow.

Air tightness: It refers to the level at which air can leave the commercial building through the roof. 

Proper ventilation: It ensures that the commercial building has adequate airflow. It also prevents heat and moisture accumulation.

You should know that different roofing systems often have different optimal measurements for solar reflectance and thermal emittance. That is why you should consult with roofing professionals who can offer certain recommendations for your commercial roofing system. They will also assist you in determining the best measures to ensure energy efficiency.

What Ideal Insulation R-value, Air Tightness, and Ventilation Should a Roof Have?

The ideal and optimal insulation R-value, air tightness, and ventilation of a roof will be according to many factors. They include:

• Climate
• Roofing system
• Overall energy efficiency goals of the building

Typically, a higher R-value signifies an improvement in insulation. It ensures that the roof keeps heat in the commercial building during winter and out of the building during summer. 

The ideal R-value for roof insulation may vary according to factors like: 

• Climate zone
• Building code
• Type of insulation

Air tightness refers to the effectiveness of a roof in blocking air from leaking out. It has a common measurement of cubic feet per minute (CFM) per square foot of the commercial building envelope area. 

A lower cubic foot per minute (CFM) number suggests a better air-sealed roof. The recommended air tightness level may be different. Nonetheless, a tighter roof is generally a better consideration.

Ventilation is crucial for the roofing system. It helps to maintain the moisture and temperature levels in the attic. As a result, it prolongs the roof’s lifespan and prevents mold, algae, or rot. 

In addition, proper ventilation reduces summer cooling expenses by expelling hot air from the attic.

An effective ventilation system requires both intake and exhaust vents. The attic size determines the dimension of both vents.

According to the National Roofing Contractors Association, a minimum ventilation rate of 1 square foot should have a vent area per 150 square feet of attic floor area. Also, each ventilator should have at least 1 square foot of vent area.

You should work with other professionals, for instance as energy consultants or roofing experts. They will help you determine the ideal air tightness, insulation R-value, and level of ventilation for your specific commercial roofing system and climate zone. 

You should also consider building codes and energy standards when recommending solutions.
