Built-Up Roofing

Built Up roofing systems have been in use in the United States for over 100 years. Built-Up roofing systems use a highly reliable waterproof membrane fabricated with layers of bitumen, and alternating with plies of reinforcing felts. The redundant layers provide outstanding resistance to water and weather. Two applications exist for this system: Hot-Applied and Cold-Applied.
