A tar and gravel roof, also known as a built-up roof (BUR), is a traditional roofing system designed for flat or low-sloped roofs. It is made by layering multiple sheets of tar and fiberglass or felt, followed by a protective layer of gravel on top. The gravel provides UV protection, fire resistance, and durability, while also weighing down the materials to prevent wind damage. This type of roof is cost-effective, long-lasting, and ideal for commercial and residential buildings. However, it requires regular maintenance to prevent leaks and damage. Proper drainage is essential to avoid water pooling, which can compromise its integrity over time.
