Tar and Gravel Roof A [tar and gravel roof](https://managemyroof.com/tar-and-gravel-roof/) is a durable and cost-effective roofing option commonly used on flat or low-slope buildings. It consists of multiple layers of waterproof tar paper, hot asphalt, and a final layer of gravel to protect against UV rays and weather damage. This type of roof is known for its long lifespan, often lasting 20 to 30 years with proper maintenance. The gravel layer helps prevent cracks and adds weight to keep the roofing materials in place. Over time, wear and tear may cause leaks, which can be repaired by adding more layers of tar and gravel. Regular inspections help identify weak spots before major damage occurs. While installation can be labor-intensive, the result is a strong, weather-resistant surface. Many commercial and residential buildings rely on tar and gravel roofs for their durability and affordability.
