Built-up roofing (BUR), also known as a “tar and gravel” roof, is another common choice for commercial flat roofs. BUR systems consist of multiple layers of roofing felt or fabric, coated with asphalt or coal tar, and topped with a layer of gravel or mineral granules. This system provides excellent waterproofing and durability, making it a reliable option for flat roofs.
One advantage of BUR systems is their ability to withstand foot traffic and provide a slip-resistant surface, making them suitable for commercial properties with frequent rooftop access. However, BUR roofs may require more maintenance over time, as the gravel can become brittle and the underlying layers may need attention.
Comparing Asphalt Shingle Alternatives
While asphalt shingles are more commonly associated with sloped roofs, there are some commercial flat roof applications where they can be used. Asphalt shingle alternatives, such as modified bitumen or metal roofing, can provide a more visually appealing and durable solution for flat roofs.
Modified bitumen is a hybrid roofing material that combines the benefits of traditional BUR with the ease of installation and maintenance of a single-ply membrane. It is available in various colors and can be an attractive option for commercial properties.
Metal roofing, on the other hand, is known for its longevity, fire resistance, and ability to reflect heat, making it a sustainable choice for flat roof applications. While more expensive upfront, metal roofs can offer long-term savings in energy costs and reduce the need for frequent repairs.
When evaluating roofing materials for your commercial flat roof, consider factors such as local climate, building design, budget, and long-term maintenance requirements to make the best choice for your property.
