Single-Ply Membrane

EPDM (Ethylene Propylene Diene Monomer): As a top choice of architects, roof consultants and contractors for both new construction and replacement roofing projects, EPDM rubber roofing membrane has the industry’s longest average service life. EPDM can be ballasted, fully adhered and mechanically attached and allows for year-round installation in all climates due to its stability over a wide range of temperatures. EPDM is also one of the most sustainable and environmentally responsible roofing materials used today in the commercial roofing industry.

TPO (Thermoplastic Polyolefin): Among the fastest growing commercial roofing products, TPO membranes provide exceptional resistance to ultraviolet, ozone and chemical exposure. Similar to EPDM, this material can be fully adhered, mechanically fastened, or ballasted. It has been reported that TPO seam strengths are three to four times higher than EPDM. Available in white, gray, and black, this has been a popular choice for “Green” buildings as there is no plasticizers added.

PVC (Polyvinyl Chloride): Dependable, heat-welded seams, high reflectivity, superior physical attributes, and resistance to water, chemicals, grease, fire, and punctures are a few characteristics that make PVC a trusted and popular roofing membrane. Through the unique heat welding installation process, a permanent bond is created between each individual PVC roofing sheet ensuring it to last a long time. Designed to be a cooling roof system, PVC membrane is ideal for any commercial and industrial facilities that deal with chemicals and solvents.

Built-up/Modified (Asphalt)

Reliability, endurance, and sustainability are three reasons why Built-Up roofing (BUR) and modified-bitumen (MB) systems are among the most popular when protecting commercial, industrial, and institutional buildings. BUR/asphalt roofs are extremely puncture resistant and durable, able to withstand extreme weather conditions from day one. As a long lasting and high performance roof system, BUR and MB are proven to be some of the lowest cost roofs to maintain. Compared to other high-performance commercial roofing systems, BUR is one of the best investments on the market and effective in meeting today’s energy codes and energy efficiency.
