Help Protect with the Power of Flex

Monday, January 28th, 2019 by Joe Stoffey

Unlike standard shingles, TruDefinition Duration FLEX shingles are made with a proprietary blend of SBS polymer modified asphalt. The rubberizing effect of the uniquely blended SBS modified asphalt makes the shingle pliable and gives them greater flexibility and enhanced durability and toughness, especially under intense storm conditions. With Duration FLEX, you are getting a shingle that has the highest impact rating possible. UL 2218 Class 4 and may qualify for a homeowner insurance discount - check with your insurance company.

SureNail Technology

There's a line between a good shingle and a great shingle.

It's the nailing line on your shingles. The difference between a good shingle and a great shingle is having SureNail Technology. With SureNail Technology, strength and durability are built into every Duration Series shingle, thanks to the unique fabric strip in the nailing area. This unique shingle design provides outstanding gripping power.

SureNail Detail

  • Patented SureNail Technoology - Only from Owens Corning and featured on our Duration Series Shingles
  • Breakthrough Design - The tough-engineered woven-fabric nailing strip is embedded in the shingle to create a strong, durable fastener zone
  • Triple Layer Protection - A unique "triple layer" of reinforcement occurs when the fabric overlays the two shingle layers, called the common bond area
  • Outstanding Grip - The SureNail strip enhances the already amazing grip of our proprietary Tru-Bond sealant
  • Exceptional Wind Resistance - The SureNail grip helps deliver 130-MPH wind warranty performance with fewer nails than required by most competitors

StreakGuard Algae Resistance Protection

Ditch the streaks - protect your home's curb appeal

Algea species are naturally occuring and transported through the air to attach themselves to shingles and other surfaces. While algae growth can cause brown or black streaks on roofs, it does not impact the performance of your shingles. Streaks caused by algae growth are most common in warm, humid climates but can occur in all regions of the country. Owens Corning has continued to advance out algae resistance protection based on over 30 years of testing and experience. Shingles with StreakGuard Algae Resistance Protection can help inhibit the growth of blue-green algae.

Wind Resistance

Significant wind can cause shingles to blow off the roof deck. Missing shingles can lead to leaks and other interior damage. The quality and performance of the sealant on a shingle helps play an important part in wind resistance performance. Owens Corning certifies out shingles to industry recognized wind resistance standards through independent third-party testing laboratories.
