Commercial Roofing Types

Single Ply Roofing

Single-ply roofing systems are applied in one layer and are either thermoplastic or thermoset. There are various types of single-ply membranes including:

EDPM (ethylene propylene diene terpolymer): This type of membrane is made from synthetic rubber. EDPM roofs are black, flexible, and require little maintenance.

TPO (thermoplastic olefin): TPO roofing systems are heat welded and have a white reflective surface that can reduce cooling costs.

PVC (poly vinyl carbonate): PVC systems are similar to TPO, but are more appropriate for use where there is exposure to chemicals, grease, oils, or fuels. This type of roof is easy to install and is heat welded.

Modified Bitumen Roofing

Modified bitumen roofing systems utilizes bitumen that has been modified to increase the flexibility and expansion properties of the membrane. This type or roof has stronger expansion and contraction properties.

There are two common types of modified bitumen roofing systems. SBS (styrene-butadiene-sytrene) and APP (attactic polypropylene) both utilize a two-ply system of overlapping membranes for increased durability and flexibility. APP roofing systems are installed using a torch, while SBS systems often use asphalt or cold-applied adhesives.

Built Up Roofing

Built up roofing systems are incredibly resistant to water and extreme weather. Consisting of a waterproof membrane layered with bitumen and felts, built up roofs are exceptionally durable and provide an additional layer of protection against damage.

Built up roofs often use asphalt, coal tar, or cold-applied adhesive that are applied to the entire roof area. Roof surfaces can be comprised of gravel, hot asphalt, aluminum, or fiberglass or elastomeric coatings.

Metal Roofing

Metal roofing is durable, low-maintenance, and available in a variety of styles and colors to suit your commercial building. Metal roofing is excellent at shedding water, ice, and snow and is resistant to decay, discoloration and mildew.

Roof coatings can be applied to metal roofs to extend the life of the roof and to enhance the roof’s weatherproofing and UV blocking properties for improved energy efficiency.

Copper Roofing

Cooper roofing lends a unique style to buildings and can be used on an entire roof or as a decorative accent. Copper roofing is energy efficient and durable.

Copper roofing is used on a number of historical buildings and government buildings but can also provide a unique style and aesthetic to contemporary buildings. Copper roofing is available in a variety of styles and textures that can make your building stand out.

Copper is commonly used for domes or as a decorative accent such as gutters and downspouts, trim work, spires, finials, and more.

Steep Slope Roofing

Steep slope roofs can be constructed from a variety of materials to provide a unique look or to achieve a specific style. Options for steep slope roofs include:

Asphalt Shingles: Asphalt shingles are a popular choice for commercial buildings. Shingles are available in numerous colors and styles to match your building’s design. It is a durable and affordable roofing option.

Clay, Slate and Synthetic Tiles: Tile roofing made of natural or synthetic materials can give your building a higher-end look and can provide greater durability and fire resistance than asphalt shingles.
