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.
"Each of the projects had many difficulties and challenges and we were especially pleased with Greenwood’s persistence and efficiency during the construction phase."
