A tar and gravel roof is a common flat roofing system used in many buildings. It consists of layers of tar, felt, and gravel for durability and waterproofing. The gravel protects the tar from sun damage and adds weight to hold materials in place. This type of roof is affordable and offers good insulation. Regular maintenance is needed to check for cracks or bare spots. It's effective in hot climates like Los Angeles due to its heat resistance. Visit: https://managemyroof.com/tar-and-gravel-roof/
