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.
Hip and pyramid roofs: as the name suggests, a pyramid roof is a roof in the shape of a pyramid and is designed for a square building. A hip roof uses the same basic shape, but is elongated and is designed for a rectangular building. The hip roof is also very popular in North America. Gambrel roof: this is also known as the barn roof, as this style is often used on barns. This roof style maximizes the amount of usable space in the attic or top floor.
