The true cost of a roof is measured over its total life, and the Duro-Last® Cool Zone® membrane‘s proven performance helps minimize life-cycle costs. Every Cool Zone roof:

• Is white through-and-through, with exceptional reflectivity and emissivity characteristics that help reduce energy bills and preserve the effectiveness of other building components.
• Has a high-density weft-insertion knitted scrim to provide strength and durability that can perform in all climates for up to 20 years or more.
• Is prefabricated to fit each roof precisely, meaning less installation waste, less on-site seaming, less chance for leaks down the road, and less lifetime maintenance cost.
• Is non-curing — new flashings and accessories can be installed easily throughout the life of the roof.
• Is backed by the industry’s best warranty, provided at no cost and offering long-term peace of mind to Cool Zone customers.

The Duro-Last® roofing system scores high marks when it comes to long-term performance. Our precision fabrication process produces a roof custom engineered for your building, with up to 85 percent of membrane seaming completed in our factory before delivery to the job site. That means your authorized Duro-Last contractor can install your roof in less time, with less disruption, and with less chance for installation problems than other roofing systems. The result? You get a leak-proof roof that lasts for decades with little to no maintenance, saving you time, money, and energy over the long haul. That’s smart thinking.
