A tar and gravel roof is commonly used on flat or low-slope buildings. It is built by layering tar and roofing felt, then adding gravel on top. The tar acts as a waterproof barrier, while the gravel protects the tar from sunlight and helps keep it in place. This type of roof is strong and can last many years with regular maintenance. It also offers good resistance to fire and harsh weather like strong winds. Visit: https://managemyroof.com/tar-and-gravel-roof/
