Duro-Last® Roofing Contracator

Bourdeau Contracting LLC is a certified installer of Duro-Last® roofing systems in St Charles MO, as well as St. Louis, Kansas City and throughout Missouri. Duro-Last® began in 1978 with the simple need to find a roofing system that worked. Existing roofing systems presented a common problem - they required ongoing maintenance and continual expense, with no long-term solution in sight. The company's founder John R. Burt, used his experience in fabricating pool liners to develop a remarkable new commercial roofing membrane. Two years of additional testing resulted in the proprietary membrane formula still in use today, after more than 30 years. Duro-Last roofing systems are ideal for commercial and industrial buildings.

Why Is Duro-Last® Roofing Better Than Other Systems?

The Duro-Last® vinyl roof membrane is a proprietary thermoplastic formulation consisting of PVC resins, plasticizers, stabilizers, biocides, flame retardants and U.V. absorbents. A weft-insertion knitted scrim that is laminated between two layers of PVC film gives the membrane its strength and durability. The Duro-Last® single-ply membrane is available in white, gray, dark gray, tan, or terra cotta.

Why Use A Prefabricated Roofing System?

For building owners and managers, Duro-Last's custom fabrication of single-ply roofing systems offers several advantages:


Their flexible roof membrane is easily prefabricated into deck sheets up to 2,500 square feet in size, as well as custom-made parapet, stack, and curb flashings that eliminate most labor from critical roof areas – transitions and changes of plane. This allows us to cover more of the roofing area, without having to make cuts or adjustments to the material. Prefabrication provides building owners peace-of-mind regarding the watertight security of the roof installation.

CoolZone® Roofing System

In addition to our standard high-quality membrane, Bourdeau Contracting LLC offers the Duro-Last® CoolZone® roofing system. What does sustainability and cool roofing really mean for building owners? It means that the design, construction, maintenance, life-cycle impact, adaptive re-use, destruction, and recycling of roofing components must help meet the long-term environmental standards demanded by today's high-performance buildings. Using a CoolZone® roof on your commercial business can significantly reduce cooling costs of your business, typically paying for itself within the first few years.
