How long do TruDefinition Duration FLEX shingles last?
When installed as part of a complete Owens Corning Roofing System, Duration FLEX shingles typically last 25–30+ years. Their SBS polymer-modified asphalt formulation helps them stay flexible and durable longer than standard shingles, especially in harsh climates like Michigan.
Are Duration FLEX shingles the same as Duration Designer?
No. These shingles serve different purposes:
- Duration FLEX is built for maximum durability, offering Class 4 impact resistance and superior cold-weather flexibility.
- Duration Designer focuses on premium aesthetics, providing rich, high-definition color blends and enhanced visual depth.
Both use SureNail Technology and provide strong wind protection, but FLEX is the durability upgrade, while Designer is the aesthetic upgrade.
Can these shingles withstand Michigan winters?
Duration FLEX shingles are specifically engineered for harsh conditions. Their SBS-modified asphalt stays flexible in extreme cold, helping prevent cracking during freeze–thaw cycles. Combined with SureNail Technology, they deliver excellent wind and storm protection, making them one of the best choices for Michigan weather.
Does RoofAdvisor register my warranty?
Yes. RoofAdvisor registers your Owens Corning warranty after installation, ensuring your system coverage is active, documented, and tied directly to your home.
