Single PLy Roofing
Unlike built-up roofing, single ply roofs are just that – one layer of roofing material as a waterproofing membrane and a weathering surface. Single ply roofing membranes are much thinner and lighter than built-up roofs. Single ply roofing is used in both residential and commercial roofing.
Single ply roofs are typically installed either in fully adhered (glued to the insulation or fiber board bellow it) or mechanically attached to the roof deck with corrosion resistant fasteners and barbed plates.
Most common single ply roofing systems today are EPDM Rubber roofing and TPO roofing systems (thermoplastic polyolefin).

Steep Sloped Roofing Systems
Asphalt Shingles possess an overwhelming share of the U.S. steep-slope roofing market. Asphalt shingles are reinforced with fiberglass materials.
Fiberglass shingles consist of a fiberglass mat, top-and-bottom layers of asphalt, and mineral granules.
Asphalt shingles fire resistances, like most other roofing materials, are categorized by Class A, B or C. Class A signifies the most fire-resistant; Classes B and C denote less fire resistance. Generally, most fiberglass shingles have Class A fire ratings, and most organic shingles have Class C ratings.
A shingle’s reinforcement has little effect on its appearance. Fiberglass products are available in laminated (architectural) grades that offer a textured appearance. Zinc or copper-coated ceramic granules also can be applied to fiberglass products to protect against algae attack, a common problem in South Florida. Asphalt shingles also are available in a variety of colors.
Regardless of their reinforcing type and appearance, asphalt shingles’ physical characteristics vary significantly. When installing asphalt shingles, NRCA recommends use of shingles that comply with American Society for Testing and Materials (ASTM) standards. ASTM D 3462 for fiberglass shingles. These standards govern the composition and physical properties of asphalt shingles; not all asphalt shingles on the market comply with these standards. If a shingle product complies with one of these standards, it is typically noted in the manufacturer’s product literature and on the package wrapper.
