Flat roofing systems are used all over the world for industrial and commercial properties. There are many options for the surfacing of flat roofs such as concrete or masonry. Other options include tar/tar paper coating or membranes. Membranes are usually applied in strips of sheets and have been used as long as 60 years. An alternative that does not come in strips is a custom fit, Duro-Last PVC membrane.  This system has been installed in nearly a million roofs, including industrial, commercial and institutional applications.

Duro-Last flat roofing systems are fabricated to exact size, and eliminate 85% of seems during installation. It improves the life-span of the roof system. Additionally, because of its lightweight vinyl material, it can be installed over the top of an existing roof system. This means no expensive tear off, and also means that the Duro-Last PVC system can be installed without interruption of day to day business. The membrane is mechanically attached so there are no loud machines, heavy debris, noxious fumes, hazardous materials or waste.

Durability

The Duro-Last system for flat roofing is made from a PVC membrane which is fire resistant, chemical and grease resistant, can withstand high winds, and reduced chance for punctures. The membrane can withstand temperature extremes, and Duro-Last's custom flashing components are made from the same vinyl. It withstands ponding water which helps solve roof problems before they can occur.
