OakRidge Shingles

OakRidge laminated shingles provide premium protection and an impressive curb appeal.  A full double layer in the nailing zone gives OakRidge Shingles greater integrity and better holding power compared to shingles with a single layer wide nailing zone.  We proved it in testing and the warming, inviting look in popular colors provide a step up from traditional three-tab shingles.


Duration Shingles

Whatever your home's architectural style, Duration Series Shingles offer a wide range of specially formulated colors that offer impressive curb appeal.  The advanced performance of patented SureNail Technology comes on every Duration Series Shingle.



Duration Flex Shingles

Duration FLEX shingles are more flexible than standard shingles, for enhanced durability and performance in all environmental conditions, including storms and cold weather installation.  They are the only SBS modified polymer shingle that also comes with the advanced performance of patented SureNail Technology for added confidence in windy conditions.

  • Patented SureNail Technology for exceptional wind resistance

  • Limited Lifetime Warranty

  • 130mph Wind Resistance Limited Warranty

  • StreakGuard Protection with 10-year Algae Resistance Limited Warranty


Made with a proprietary blend of SBS polymer modified asphalt, the rubberizing effect of the unique asphalt blend makes the shingles pliable and gives them greater flexibility than standard shingles.  The result is a premium architectural asphalt shingle with enhanced durability and toughness, especially under intense storm conditions, to help deliver lasting protection to your home.

  • Feature SureNail Technology which gives a 42% better nail-pull resistance against the wind versus standard shingles

  • Has built-in flexibility to help resist cracking and tearing, in all-weather installation conditions - over 10% stronger tear strength than traditional shingles.

  • Lays flat faster than standard shingles

  • Offer rubber like flexibility to withstand expansion and contraction stresses and helps minimize loss of granules which help to protect the shingle against UV.

  • Help absorb the energy of the impact of hail or storm debris; have the highest impact rating possible, UL 2218 Class 4 and may qualify for a homeowner insurance discount.*


Underwriters Laboratories (UL) has one of the most demanding standards for testing the impact resistance of shingles.  The UL 2218 test determines the amount of stress a newly manufactured roofing shingles can withstand without cracking.  It also rates the shingle's performance.  Duration FLEX shingles have achieved the highest rating possible - Class 4.

How The Testing Works:

  • Four different sized steel balls are used to simulate the force of free  falling hailstones

  • To test impact resistance, shingles are struck twice in the same spot

  • A class rating is assigned to signify resistance to a particular size steel ball - the higher the class rating, the greater the resistance
