**Tar and gravel roofs**
[Tar and gravel roofs](https://managemyroof.com/tar-and-gravel-roof/) are commonly used on flat or low-slope buildings. They are made with layers of roofing felt and hot tar, topped with gravel. The gravel protects the roof from sun damage and adds weight to keep materials in place. This type of roof is durable and can last up to 30 years with proper care. It offers good insulation and resists water when installed correctly. Repairs are usually easy and involve patching worn or cracked areas. Regular cleaning and inspections help keep the roof in good shape. Tar and gravel roofs are a cost-effective option for many homes and businesses.
