We can help you to understand the features and benefits of each type of system.
Built-Up Roofing (BUR)
Built-up roofing (BUR) is a very economical choice for flat roofs. It is composed of three or more layers of fiberglass membrane coated with hot asphalt, with a top layer of gravel or mineral blends to protect the surface from weather, UV rays and mechanical damage.
Modified Bitumen Roofing
One of the most common residential low-slope systems, modified bitumen combines hot asphalt (bitumen) with plastic and rubber additives which are layered between sheets of fiberglass or polyester. Its lifespan is determined by the number of layers installed. Modified bitumen roofing exhibits many characteristics of BUR, yet affords the ease of application of a single-ply system. These membranes are resistant to heavy traffic, punctures and tears.
EPDM Single-Ply Membrane
Often referred to as rubber roofing, EPDM (ethylene propylene diene monomer) membrane is a rubber-based product with a proven reputation for durability. Varied application techniques include ballasted, fully adhered and mechanically fastened, allowing EPDM roofing systems to be applied to virtually any roof surface.
PVC/TPO Single-Ply Membrane
Thermoplastic single-ply membranes represent the fastest-growing segment of the U.S. commercial roofing market. Short for polyvinyl chloride, PVC is a sturdy, single-ply roofing membrane proven to perform well on both residential and commercial roofs. TPO, or thermoplastic polyolefin, is a newer heat-welded, single-ply roofing membrane that costs less than PVC and offers a 10-year rating. TPO reflects solar heat, making it a popular choice where energy efficiency is important. Both PVC and TPO are aesthetically pleasing, lightweight and highly resistant to wear.
While expensive compared to other commercial systems, metal requires little maintenance and often lasts 50-75 years. When it comes to fire, wind and impact resistance, metal roofing stands alone. With reflective coatings applied, metal can also be used to keep utility costs low. Its recycled content, recyclability and energy efficiency qualifies it as a “green” building product.
