A common roofing method, particularly for flat or low-sloped roofs, is a tar and gravel roof, sometimes referred to as a built-up roof (BUR). This kind of roof has several layers of tar or asphalt with a protective layer of gravel on top. While the gravel adds weight, stability, and UV resistance, the tar creates a waterproof barrier. Roofs composed of tar and gravel are renowned for their resilience to severe weather. Visit: https://managemyroof.com/tar-and-gravel-roof/
