Built-Up Roofing (BUR)

Built-up roofing is the original commercial flat roof system, with over a century of proven performance protecting buildings worldwide. Edison Roofing Contractor installs modern BUR systems that combine this time-tested multi-layer approach with contemporary materials and installation techniques for superior waterproofing and durability. A built-up roof consists of alternating layers of bitumen and reinforcing fabric, topped with a protective surface of aggregate, mineral cap sheet, or reflective coating. This multi-ply construction creates inherent redundancy that membrane systems simply cannot match. Each layer adds waterproofing protection, meaning the system continues performing even if the surface layer is damaged by foot traffic, falling debris, or weather exposure. Our BUR installations use fiberglass or polyester reinforcing felts with either hot-applied asphalt or cold-applied adhesive depending on your building occupancy and local fire code requirements. We design systems with three to five plies based on your performance requirements and warranty objectives. The gravel surfacing option provides excellent UV protection, hail resistance, and fire rating, while smooth-surfaced BUR with reflective coatings offers improved energy efficiency. For building owners who value proven technology, redundant waterproofing, and the ability to walk on their roof without worrying about membrane damage, built-up roofing remains an excellent choice. Our BUR installations are backed by manufacturer warranties and our own workmanship guarantee.
