Single Ply Roofing Systems are a one-layer membrane. Single Ply membranes include PVC (Polyvinyl Chloride) and TPO (Thermoplastic Polyolefin). These systems are lightweight, quiet, and odorless to install, and they are usually Title 24 compliant. It is also the only roofing system that is still under warranty if ponding water occurs.
Single Ply Systems are usually more expensive than BUR and Modified Bitumen Roofing Systems. The biggest advantage they offer is the warranty remaining in effect for ponding water. If a BUR or Modified Bitumen Roofing System ponds water, the manufacturer will not warranty the roof in those areas. The life expectancy for Single Ply Roofing Systems is usually the longest out of all the commercial roofing options.
I was very happy with Midwest Roofing's work. We had scheduled a different company, but when the season got busy they stopped returning our calls. This never happened with Midwest. They maintain good communication, and all of our calls were returned promptly. They were extremely competitive on the pricing. Mark was the supervisor, and he handled everything perfectly . . .
