A tar and gravel roof is a durable, weather-resistant option commonly used on flat or low-slope buildings. It consists of layers of roofing felt soaked in hot asphalt, topped with gravel to protect against sun damage and wear. This type of roof provides excellent waterproofing and insulation, helping to keep buildings cool in hot weather. Over time, however, the gravel can shift, and cracks may form in the tar, leading to leaks. Regular maintenance, such as adding more gravel or patching small cracks, can extend its lifespan. While installation can be labor-intensive, the result is a strong, long-lasting roof. Many commercial and residential buildings choose this roofing for its affordability and durability. Proper care ensures it remains effective for decades.
