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 unique fabric strip in nailing area. This unique shingle design provides outstanding gripping power.

  • •Patented SureNail Technology – Only from Owens Corning and featured on 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.


  • Attic ventilation is important to keep the air flowing through your attic, rather than simply letting it sit. Ventilation essentially helps outside air pass through and out of your attic, removing excess heat and moisture from the air of your attic as it does so. Air is taken in through areas like your soffits and eaves, then is exhausted through the roof at your ridge cap or by a roof vent. This helps create the right air balance in your attic, which plays an important role in ensuring the longevity of your roof.
