Owens Corning Duration shingles are premium architectural asphalt shingles reinforced with a fiberglass mat and designed with Owens Corning's patented SureNail® Technology.
Unlike standard three-tab shingles, architectural shingles like Duration have a multi-layered, dimensional profile that provides enhanced visual depth and greater resistance to wind uplift and impact.
Duration shingles are part of Owens Corning's TruDefinition® line, meaning they're engineered to deliver bold, consistent colour contrast across the roof surface, giving your home a cleaner, more polished look that holds up over time.
Available in a wide range of colours to complement any exterior style, they're a popular choice for Calgary homeowners looking to balance curb appeal with long-term protection.
Owens Corning backs Duration shingles with a lifetime warranty when installed by a qualified contractor according to their published specifications. This warranty also includes wind resistance coverage provided the shingles are installed with the correct fastening pattern and in compliance with local building code requirements, which we always follow.
The defining feature of Duration shingles is SureNail® Technology, a proprietary woven fabric strip embedded in the nailing zone that improves fastening accuracy, increases holding strength, and delivers superior wind uplift resistance. For Calgary homeowners in a high-wind region, it’s a measurable engineering advantage, not just a marketing claim.
Owens Corning Duration shingles incorporate StreakGuard® Algae Protection, using copper-infused granules to prevent the dark streaking that algae growth causes over time. Whether you’re planning to sell or simply want your roof looking sharp years down the road, it’s a feature that pays off.
Duration shingles are manufactured under Owens Corning’s TruDefinition® process, which produces more vibrant, consistent colour variation across each shingle and across the entire roof. The result is a roof surface with genuine visual depth rather than a flat, uniform look.
Calgary's climate is hard on roofing systems. Temperatures can swing 30 degrees in a single day, ice dams form along eaves in winter, and summer hailstorms can cause significant granule loss on lower-quality shingles. Owens Corning Duration shingles are engineered to handle this kind of variability, designed to perform reliably across wide temperature ranges without cracking, curling, or losing granule adhesion prematurely. Beyond weather performance, homeowners choose Duration shingles for several practical reasons:
Before any materials are ordered, we conduct a thorough inspection of your existing roof structure, decking condition, ventilation balance, and site-specific exposure factors. In Calgary, this includes evaluating ice dam risk zones, slope orientation, and any drainage concerns.
Based on the inspection, we develop a complete system plan that specifies the appropriate Owens Corning Duration colour and profile, along with compatible components — starter strips, ice-and-water protection, synthetic underlayment, ridge cap, and ventilation products.
Our installation crews are trained to work within the SureNail nailing zone on every shingle, ensuring consistent fastening depth and placement across the entire roof surface. This isn't a shortcut, it's the correct way to install Duration shingles and a requirement for full warranty eligibility.
Valleys, pipe boots, skylights, chimneys, and wall intersections are common leak points on any roof. We take flashing details seriously, using compatible materials and proven methods to seal every transition correctly.
We inspect the roof decking for any soft spots, damaged panels, or areas that need repair or replacement before new materials go down. A solid, properly fastened deck is the foundation of a long-lasting roof.
In Calgary's climate, proper protection along eaves, valleys, and penetrations is non-negotiable. We install self-adhering Ice and Water Shield in vulnerable areas and cover the remaining field with high quality synthetic underlayment for a secondary moisture barrier.
Proper attic ventilation protects your shingles from heat buildup in summer and moisture accumulation in winter, both of which accelerate shingle aging. We evaluate your intake and exhaust ventilation balance and make corrections where needed as part of every complete installation.
Once installation is complete, we conduct a final walkthrough to verify fastening, alignment, flashing integrity, and overall workmanship. We leave your property clean, and we make sure you understand your warranty documentation before we close out the project.
Yes. Duration shingles are engineered to perform across wide temperature ranges and resist wind uplift, both important considerations in Calgary and across southern Alberta. Their SureNail Technology is particularly valuable in windy regions, where shingle blow off is a real risk with lower-quality products or poor installation.
In most cases, yes. Duration shingles are suitable for a wide range of roof slopes and home styles. A proper inspection will confirm whether your roof structure and decking are in appropriate condition for a new installation and whether any preparatory work is needed beforehand.
