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.
Ridge vents are installed at the ridgeline of the roof, and cap shingles or cap components are placed on top of the vent. Metal roofs have topped barns, buildings and country homes in the United States since the 1700s. But today's metal roof is nothing like the familiar standing-seam tin roof of years ago.
