Built-up roofing (BUR) is one of the oldest options for material for flat roofs or roofs that are very low in pitch. BUR systems are constructed with several layers of roofing felt impregnated with asphalt that is applied hot. The felt is applied in overlapping layers to form a barrier two to four layers thick, then a layer of finely crushed stone is embedded in hot tar over the top to create a very durable and impenetrable roof.

Modified bitumen (MB) torch down roofing is asphalt based, built-up-roof (BUR) roofing systems designed for buildings with low-slope or “flat” roofing structures. Mineral surfaced MB products are typically furnished with white granules, but are also available in designer color to match asphalt or to otherwise compliment the building. Dibiten is a superior APP modified bitumen membrane reinforced with a high quality nonwoven polyester mat and is one of the finest heat weld applied modified bitumen membranes ever produced not only for residential roofing but for commercial and industrial roofing as well. We also do single ply roofs.
