Essentially, it’s the top layer of a multi-ply roofing system—most commonly used on flat or low-slope roofs. Constructed from materials like modified bitumen or fiberglass, cap sheets deliver durability, water resistance, and UV protection. They’re typically installed as part of built-up roofing (BUR) or modified bitumen systems, forming a reliable weatherproof barrier. Homeowners value cap sheets for their easy maintenance and relatively straightforward installation: after lower layers are placed, a cap sheet is rolled out, adhered or torched down, then sealed at the seams. Besides protecting from leaks, the cap sheet can enhance curb appeal, as manufacturers offer colors and finishes to complement your home’s style. As a designer, I see cap sheets not just as a protective solution, but also as an opportunity to integrate roofing choices into the overall aesthetic of a home—helping ensure harmony between structure and style.
