Built Up Roofing


With Built-Up roofing systems, the highly reliable waterproof membrane is field fabricated with layers of bitumen, alternating with plies of reinforcing felts. The redundant layers give it exceptional resistance to water and weather.

Started in the 1840's, these roof systems are often referred to as "tar and gravel" roofs. BUR consists of multiple plies of roof felts laminated together with bitumen. BUR consists of bitumen-saturated organic-fiber, fiberglass, or polyester felt. A top-surfacing or a glaze coat of asphalt, aggregate (gravel or slag), fibered, or non-fibered coatings engineered for roof coating, or a granule-surfaced cap sheet.

BUR may be designed and specified to meet a broad range of building waterproofing applications, depending on the needs of the building owner. These systems range from very basic systems designed to be vigorously maintained to upper-end systems that are constructed to qualify for a manufacturer’s warranty. Roofing manufacturers, working in close coordination with our roofing experts, will write long-term warranties for building owners based on specific design criteria.

Over the years, BUR has earned a great reputation with building owners, architects, engineers, roofing product manufacturers and commercial roofing contractors. The original cost of a BUR system may be greater than other low-slope applications, but when taking the long view, BUR often comes out a winner. BUR enjoys a track record that is over 150 years old, provides a thick, durable roof covering, may be used in a broad range of building waterproofing applications, and after many years of service may be maintained and repaired for extended life (many other systems must be completely replaced).
