Tar and gravel roofs are made using layers of tar, fabric, and small stones. The tar helps stop water from leaking into the building, while the gravel on top protects the tar from the sun. This type of roof is best for flat or gently sloped surfaces. It is strong, lasts a long time, and can handle different kinds of weather. Visit: https://managemyroof.com/tar-and-gravel-roof/
