Custom Prefabrication
The majority of the long-term problems that arise with most Prefab flat roofing systems are due to installation workmanship. By performing 80-85% of membrane seaming in a controlled factory environment, Duro-Last reduces the potential for rooftop installation errors and leaks. Custom-fabricated stacks and curb flashings also eliminate most on-site work at critical roof areas, such as penetrations and transitions.
