Commercial Roofing Systems

Commercial roofs are very different from residential or domestic house roofs. They are bigger, stronger and need to be versatile enough to support a wide range of activity associated with commercial roofs. There is a variety of commercial roofing types with each designed to thrive in a specific environment. Here are the top commercial roofing types and where they thrive best.

Modified Bitumen Roofing

This asphalt-based roofing system is reinforced with fiberglass or polyester to give it an extra punch. This makes it resistant to tears and punctures, making it an excellent choice for roofs expecting considerable foot traffic. You can choose between APP (Atactic Polypropylene Polymer) modified bitumen that offers better tensile strength or opt for SBS (Styrene Butadiene Styrene) modified composite that gives you better resistance to brittleness at low temperatures.

The Built-Up Roof

Built up roofs can be custom made to meet a range of waterproof, puncture, and weathering standards. The construction team uses multiple layers of mats, fabrics or felts laminated with coal tar pitch, asphalt, or bitumen. This gives you the flexibility to choose what goes into the roofing material plies, its thickness, and what you will finish the roof with. The result is a highly customized roof that can be modified to suit a wide range of applications.

EPDM (Ethylene Propylene Diene Terpolymer) Roofing

EPDM is a single ply rubber roofing material that offers impressive resistance to UV, abrasion, weathering, and ozone. EPDM is among the best roofing systems on the market thanks to its impeccable tolerance to a wide range of weather elements. You will need to choose between:

  • Ballasted systems which are the easiest and fastest to install. This has made them account for over 35 percent of current EPDM roofs
  • Mechanically attached systems are a lightweight solution to weaker roofs where the membrane is draped over the structural deck using mechanical anchor points
  • The fully adhered application uses an adhesive to bond the membrane straight to the roofing substrate. This is the favorite technique on delicate roofing designs like barrels and domes

Other popular commercial roofing types include the use of thermoplastic systems and the traditional metal roof. Coated systems are a perfect way to upgrade an existing roof, and sustainable roofing solutions that turn the roof into an environmental friendly zone by giving it features that reduce the building’s energy consumption (like solar panels and prismatic skylights).
