What is a Roofing Cap Sheet. Used in low slope roofing such as built-up roofing (BUR) or modified bitumen roofing, a cap sheet is used to create a water-tight surface. Constant exposure to wind and weather can cause a BUR roof to become brittle and crack, then water can seep into the cracks, eventually working into the interior of the building.
Surfacings for these roll materials consist of a smooth surface, or mineral granules, aluminum, copper, or an aggregate such as gravel or slag that is set it hot asphalt. Modified Bitumen roof systems consist of one, two, or three ply systems. The type of substrate will often determine the type of system being installed. 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.
