For flat or low-slope buildings, a built-up roof (BUR), sometimes referred to as a tar and gravel roof, is a long-lasting choice. It is made up of several tar layers, reinforced with felt or fiberglass, and then covered with gravel. Foot traffic, weather damage, and UV rays are all prevented by the gravel. When properly maintained, this kind of roofing is renowned for its durability and resistance to leaks. Visit: https://managemyroof.com/tar-and-gravel-roof/
