Commercial and Residential Flat Roofs

  • Asphalt - BUR
  • EPDM
  • TPO - TPO roof membranes are a blend of polypropylene (PP) and ethyle-propylene rubber (EPR) polymers. The chemical and physical characteristics allow the single ply membrane to repeatedly soften when heated and harden when cooled. In addition, because of their chemical nature, seams are heat welded with hot air. Some TPO membranes are soft and flexibles, while other are rigid, although all TPO membranes have positive phisical properties, such as heat aging, cold temperature flexibility, punture resistance and tear stregth. All TPO membranes are installed by manufacturer's guidelines.
  • APP - APP is asphalt with modifiers added to give either a plastic or rubber properties and qualities. APP is a torch down applications. Rolls of APP have a variety of surfaces.
  • SBS - Is the same material as APP, but is a different application. Rather than torch down
  • SBA - Is either glued or self-adhering.


A built up roof (BUR) membrane is a continuos, semi-flexible roof membrane. It consists of multiple layers sometimes referred to as "redundant system" of coated of saturated roll roofing material, and bitumen. The roll roofing material can be felt or sheets such as base ply and cap sheets, reinforced fabric or polyester, fiberglass or both used with bitumen of asphalt, polymer-modified asphalt, coal tar or solvent-based asphalt.
This is then surfaced with mineral aggregate, bituminous materials, liquid applied coating or granule surface cap sheet. Membrane flassing typically made of a backer layer or layers of cap sheet are used at the roof perimeter and penetrations. The material used will depend upon the application
