Tar and gravel roofs

[Manage My Roof]

Tar and gravel roofs are common on flat or low-slope buildings. They are built using layers of tar and roofing felt. Gravel is spread on top to protect the surface. The tar makes the roof waterproof. Gravel helps block sunlight and adds weight to hold materials down. These roofs are strong and long-lasting. They can resist fire, wind, and weather damage. However, they are heavy and need a sturdy structure.
