Built-up roofing, or BUR, is comprised of alternating layers of ply sheets, bitumen layers and a gravel-like top surface. Most commonly used for low-slope or flat roofs, BUR creates a sealed surface. This differs from shingle roofing in that built-up roofs are continuously sealed, while roof shingles are not and therefore require a steep slope to effectively protect against the elements.
BUR roofing has an average lifespan of 15-30 years, depending on climate and materials. Once installed, this low-maintenance roof provides waterproofing, ultra-violet protection, and fire-resistance. We can install a durable, attractive built-up roof that will protect your business from the elements for years to come. Built-up roofing is popular among business owners because it is:
- Waterproof, even for flat or low-slope roofs
- Ultra-violet protecting
- Easy to repair
