Tar and gravel roofs, often used on flat or low-sloped roofs, are a traditional and durable roofing system. They consist of multiple layers, including a base sheet, a layer of hot tar, and a final layer of gravel. The gravel protects the underlying layers from UV rays, helps with water drainage, and provides additional stability. These roofs are known for their ability to withstand harsh weather conditions, making them ideal for commercial buildings. Although tar and gravel roofs are long-lasting, they require regular maintenance to prevent leaks and ensure their longevity. Their weight and durability offer added security against strong winds and storms.
