Roofing Systems

Durability, design versatility and installation ease are among the many reasons EPDM is the most popular material for both new and re-roof low-slope roofing applications.
 EPDM membranes may be installed in a full range of system applications. The earliest predominant design was the ballasted roof, in which the membrane is loosely laid over the substrate (usually loose laid insulation). The membrane is then covered with a layer of ballast, stone or pavers, which serve as the anchoring method that keeps the membrane in place when exposed to wind uplift forces. EPDM membranes may also be fully adhered to rigid insulation board or an appropriate structural deck. This system eliminates the weight of the ballast and leaves the membrane exposed, thus offering many opportunities for aesthetic appeal through the use of specially colored membranes and coatings or just the smooth, clean appearance of an adhered black membrane. Mechanically attached EPDM roof systems are also available.

Thermoplastic single-ply roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages. TPO is a flexible, hot-air welded thermoplastic polyolefin (TPO) roofing membrane available in both 8’ and 10’ widths. Featuring a white, tan or gray reflective surface, TPO can help reduce a building’s cooling requirements.

Mechanically Attached Systems require mechanical attachment of the insulation to the deck and mechanical attachment of the membrane within the seam area.

Outstanding weathering characteristics, energy efficiency, installation ease and durability are among the many advantages of polyvinyl chloride (PVC) roofing systems. This hot-air welded, polyester scrim-reinforced membrane has a white, reflective surface, and is available in 45-mil and 60-mil thicknesses.

Ballasted designs combine a loose-laid insulation and membrane and the use of ballast or pavers to secure the system.

Asphalt systems include the different types of roofs such as pre-manufactured Modified Bitumen membrane system, a standard built-up system, or a hybrid BUR/Modified Bitumen system.
 
A SBS Modified Bitumen Roofing System combines exceptional elongation and fatigue resistance properties with the strength of a glass-reinforced polyester mat. Available in white, black and other granule surface colors, SBS membranes may be installed by heat welding, hot asphalt, cold-applied adhesive, mechanical attachment or as part of a self-adhered system.

A Standing Seam Metal Roofing System attributes are impressive. Durable and long lasting, a metal roof requires little maintenance, can be retrofitted over many existing roofing materials, is available in a wide range of colors and styles, and is fire resistant. This type of system is very popular on shopping centers and other commercial properties.
