Commercial Roofing

Single-ply membranes are highly durable and resistant to tears and leaks. They are also energy efficient, helping reduce utility costs. The roof’s structural materials play a significant role in the overall cost of commercial roofing. The material’s condition also directly impacts how much time is needed to complete the reroofing project. This is why a professional roofer should always inspect these components to ensure they are in good shape before installing the roof system.

A roof’s cover board is the protective layer encasing the internal roof components from external elements such as rain and wind. It is critical to choose a quality cover board that will provide a long service life to reduce the risk of leaks and extend the longevity of the roofing membrane. The most common choices are non-combustible gypsum, fiberglass mat or flat glass mat.

Commercial roofing is usually made of a variety of single-ply or built-up membranes that are installed over the roof’s structural deck. Single-ply membranes include TPO, PVC and EPDM while BUR systems are typically made of alternating layers of bitumen and fabrics called roofing felts. These layers are fused together by heat and adhesives to create a durable roof membrane.

These roof membranes protect a building’s interior by keeping heated and cooled air inside while allowing outside air to pass through the roof, reducing heating and cooling costs for the interior of the structure. They are available in various thicknesses to suit different design requirements and roof climate conditions.

Other types of commercial roofing include shingle roofs which are popular for their affordability and durability, metal shingles that can be made to look like real wood shakes, slate or Spanish tile, and concrete tiles which are durable, fire resistant and low maintenance.

Commercial roofing requires a robust drainage system to avoid water pooling and foundation issues. The most common drainage systems include gutters, downspouts and scuppers. These are often combined with a vapor barrier to prevent moisture from contacting the interior walls and ceiling of the building. For sloped roofs, the drain system may also include a valley or drain gutter. A vapor barrier is also recommended for flat roofs. This is a protective layer that stops moisture from seeping into the roof’s interior and into crawlspaces or basements.


Commercial roofing is a crucial part of any business, as it protects the occupants and contents of the building from rain and snow. Commercial roofs are usually flat or have a low slope and are larger than residential roofs. These roofs also have unique installation considerations. Roofing contractors must be familiar with the building and its features, including smoke stacks, air flow systems, external piping, and other equipment. Commercial roofs can be more complex than residential roofs and typically require more maintenance and repair. This makes it important to have a comprehensive understanding of the costs associated with commercial roofing.

There are six common types of commercial roofing. Each has its pros and cons. Some are more affordable than others, but they all provide a solid level of protection from weather elements.

Single-ply membranes, such as EPDM or TPO, are the most popular choice for commercial roofs. These are wide sheets that can be applied to flat or low-slope buildings and have fewer seams and gaps than other roof types, which reduces the risk of leakage. These roofs are also lightweight and offer energy efficiency benefits.

Built-up roofs, or BUR, use gravel and tar to create a waterproof layer. This type of flat roof is a durable, long-lasting option but can be expensive to install and maintain. Modified bitumen is an asphalt-based roof system that was created in the 1960s and offers more flexibility than BUR.

Asphalt shingle roofs are a more traditional, cost-effective option. They are a durable, versatile roof system that comes in a variety of styles and colors. Some asphalt shingles even come with “lifetime” warranties.

Metal roofs are an alternative to asphalt shingles and offer durability and longevity. They can last 50 years or more and can improve a building’s energy efficiency. Metal roofs are also easy to repair, making them an economical option for a commercial roof.

It is critical to hire a professional roofer with experience working on commercial buildings. Not only will a quality contractor have the skills needed to perform an accurate and thorough inspection, but they will be familiar with the various materials and installation methods that are available for commercial roofing. They will also know how to properly care for and maintain the structure after it has been installed.


When it comes to roofs, most people think of the material that covers the visible surface of the home or business. Less well known is the underlayment, which is an important piece of the roof’s makeup that protects the home from moisture and ice dams. Underlayment also allows the roofing material to lay smoothly and improves energy efficiency. It’s available in different types, weights and installation styles and can be replaced as needed or when the roof is replaced.

Felt underlayment, which is made from organic materials such as wood fibers or paper that’s saturated with bitumen, remains the most popular choice for many homeowners. It’s available in 15-pound (No. 15) or 30-pound varieties and is less expensive than some synthetic options. However, it has limitations and should not be used in high-wind zones or around chimneys, skylights or vents because it can tear during installation.

Synthetic underlayment is typically manufactured from plastics or polymers, including a combination of these materials. It’s lightweight and easy to install, which makes it a good option for do-it-yourself projects. It’s more resistant to fungal growth and wrinkles than felt underlayment, is vapor impermeable, and can withstand temperatures up to 250 degrees Fahrenheit without degrading.

It’s also more durable than felt underlayment, which can tear during installation. It is a great choice for homes in cold environments because it presents an effective air barrier and can prevent frost damage. Synthetic underlayment is often referred to as a “waterproofing membrane” or “modified bitumen.”

Rubberized asphalt underlayment, which is made from rubber polymers and asphalt, offers the highest level of waterproofing. It’s typically installed in leak-prone areas, such as eaves, valleys, vents, chimneys and skylights. It’s also a good choice for sloped roofs because it can provide additional waterproofing where water tends to accumulate. It’s usually rolled out in a single layer and is fastened to the roof deck using an adhesive. It’s not recommended for use under wood shake or shingles, and it may void the manufacturer’s warranty for these products. It’s also more expensive than synthetic underlayment.


The cost of labor for commercial roofing can vary based on the scope of the project and the local contractor rates. Cleaning and removing debris, repairing any leaks or damage, and working around HVAC systems are just some of the tasks involved in maintaining and reroofing commercial roofs. The type of roof and its accessibility will also affect the labour costs, as well as any extra features such as skylights. In addition, taller buildings may require more workers due to safety concerns and the need for higher scaffolding. Lastly, permits and inspection fees must be factored into the overall cost.
