You should be well-aware that not all single-ply membrane is created equal – TPO, PVC, and KEE all have very different formulations, specs, durability, and cost. Built-up roofs are installed using hot or cold asphalt sandwiched between several layers of rolled fiberglass or polyester membrane with a granulated, gravel or smooth coated surface.
Commercial Flat Roof System Option 1: SINGLE PLY ROOFING

Building owners who want their roof to last as long as possible or who need extra resistance to weather and chemical attack.
Commercial Flat Roof System Option 2: BUILT-UP ROOFS (BUR)

Built-up roofs, also regarded as BUR are mainly built with three or more piles of reinforcing membrane alternated with hot tar then covered with a layer of gravel, granule surfacing or a smooth coating.

BUR roofs are popular since they have been proven performance and can be less expensive than the other roofing materials. BUR roof systems are well insulated because of the many layers and a gravel surface that is a good fire retardant. A gravel surface is attractive, which is important if there are windows overlooking the roof.

Commercial Flat Roof System Option 3: TPO & PVC FLAT ROOFING SYSTEMS

TPO and PVC are the most common types of thermoplastic roof membranes that can be repeatedly softened by heating and hardened by cooling. The membranes are generally joined together by heat welding. TPO sheets contain substances that include colorant, flame retardants and UV absorbers to attain the desired physical properties. PVC sheets are made through calendaring, spread coating, or extruding. They are generally reinforced using polyester, glass-fiber mats or scrim and contain plasticizers, stabilizers, and other additives to achieve flexibility and other desired physical properties. The sheets are usually secured with fasteners, but some installs are fully adhered with glue to the substrate.
