SBS Roofing Installation
SBS is one type of Modified Bitumen roof system. A wide range of reinforcements can be used in SBS roofing materials, including fiberglass and polyester. The substrate often determines the type of system being installed. Fiberglass mats and polyester reinforcements are the typical bases for these products. Fiberglass weighs less at about 1.0 to 2.5 pounds per 100 sq. ft. and Polyester weighs in at 3.5 to 5.0 pounds per square feet. The weight can influence work efficiency and strength over time, so we can help you choose what is best for your project.
Modified roofs have proven performance on residential, commercial, and industrial applications. Roof help recommends all modified roofs be installed on slopes not less than 1/4" per horizontal foot (stated "quarter in twelve" or "quarter-inch slope") in order to achieve positive drainage.
