Roofing Endurance That Passes the Test of Time

In terms of High-Performance Roofing, endurance is the ultimate reflection of the performance of every roofing component in terms of reliability, water absorption, wind and fire resistance, maintenance, and repair. No matter how “cool” or “green” a roof is, it still has to protect the building – for years – in all types of weather – a reality that is sometimes neglected in sustainability discussions.

If you're looking for a roof that will last, consider our track record. More than one billion square feet of Duro-Last membrane have been installed throughout the U.S. and Canada since the late 1970s – and many of these roofs are still in service. What makes a Duro-Last Cool Zone roofing system so durable? Each roof we make is:

• Resistant to water, fire, chemicals, grease, and punctures 
• Able to stand up to all types of weather – including high winds and extremes of hot and cold 
• Virtually maintenance free, unlike other roof materials that may require regular patching and repairs 
• Reinforced with a high-density weft-insertion scrim for exceptional strength and durability 
• Confidently backed by the industry’s best warranties. Duro-Last protects commercial and industrial building owners with either a 15-year full warranty or a 20-year prorated warranty. Both are transferable, and both provide maximum protection. Our standard warranty includes coverage for consequential damages that result from defects in the Duro-Last material and/or installation. 
• GEMSOR Roofing Inc. installs Duro-Last Cool Zone Roofs in GTA, Brampton, Mississauga, Oakville, Toronto, Burlington, Hamilton, Georgetown, Acton,  Richmond-Hill, Vaughan and surrounding areas.

Not only does a Duro-Last Cool Zone roof perform well over the years, it can actually help extend the useful life of other building components. By keeping moisture out while reflecting ultraviolet (UV) and infrared (IR) radiation, it can help to protect underlying insulation and the roofing substrate from deterioration.

To help promote Endurance for the long-term, building owners should ensure that a new roof:

• Is properly designed for the location, climate, roof deck and type of building 
• Is installed professionally. Defective workmanship accounts for roughly 30 percent of roofing failures 
• Has physical properties that will stand the test of time: solar reflectance and emittance, tensile strength, water absorption, fire resistance, wind uplift, elongation and thermal expansion, dynamic puncture resistance and resistance to rooftop contaminants such as acid rain and air pollution 
• Is inspected and maintained regularly. This includes limiting the access and traffic on the roof.
