Hi my name is Jim McLain. I’m with Canyon State Roofing. I’ve been roofing in Arizona since 1982 and I truly know it better way. My company’s mission is to educate our customers.
We give them all the facts. We give them all the information they need to make an educated choice. From your first phone call through the project and through your warranty period, you will realize that Canyon State Roofing lives by our core values. I’ve installed every roofing material on the market, and I’ve seen a lot a roofs fail.
That’s why I chose to showcase Duro-Last roofing, the world’s best roof. Today we are installing a Duro-Last PVC roof on this warehouse. Duro-Last is a PVC membrane that is manufactured with plasticizers and algaecides.
It eliminates the chance for biological attack, caused by dirt and debris, moisture, and often times the salt from evaporative coolers, which prematurely destroys other roofing materials. It’s manufacturing process includes a polyester scrim.
Duro-Last scrim has a unique weave which makes it virtually tear proof. Since the sheets on this project are custom pre-fabricated, the sheets need to be stretched to ensure a smooth application. In this case, the sheets are 20 feet wide and 100 feet long.
Here we are using a grip pull to pull out wrinkles in the sheets. A grip pull is used to pull the sheets to pull the wrinkles out and then they are mechanically fasted through the insulation, and into the plywood substrate. The quantity and location of each fastener is determined by engineers at Duro-Last. The engineers at Duro-Last take into consideration the building height, size, substrate, and parapet wall height.
The manufacturing process back at the Duro-Last plant allows us to create up to 2500 square foot sheets. This allows for huge savings on labor costs, because field seams are minimized. This is just one reason why Duro-Last is better than the rest.
All the seams are hot air welded. This is a computerized walking welder, which minimizes the chance of error while welding, and maximizes production. Duro-Last does not use adhesives.
The hot air welder is melting the two sheets together, creating a monolithic surface. This process eliminates the need for adhesives that other manufacturers use, which have been proven to break down over time. Call Canyon State Roofing today at 602-400-1635. Lets see if a Duro-Last PVC roof is the best choice for your roofing project. Thank you for watching!
