There aren't the odors and fumes that accompany built-up roofs which appeals to many property owners and managers. EPDM roofing is designed to exhibit superior flexibility, high strength, and outstanding weathering in practically all climates. The three standard applications for EPDM are fully adhered, mechanically attached, and loose-laid.

Modified Bitumen roof systems consist of one-, two-, or three-ply systems. It is installed either by torch or hot asphalt, with a base sheet followed by interply sheet(s), and then a cap sheet. Modified membranes can also be installed in conjunction with built-up roof materials, such as multiple plies of fiberglass felt, to form a hybrid roof system. Modified roof systems have proven performance on residential, commercial, and industrial applications. |
