Atlas Roofing Debuts New StormMaster® Hip & Ridge Shingles with Core4™

“With the introduction of our Core4 technology in StormMaster Hip & Ridge, Atlas is reaffirming its commitment to providing the best quality shingles on the market.” —Stan Bastek, vice president of sales and marketing, Atlas Roofing

Atlas Roofing Corporation is proud to announce the launch of its StormMaster® Hip & Ridge Shingle with its proprietary Core4 ™ Enhanced Polymer technology that enables the shingle to offer added strength, flexibility, durability and extreme weather resistance.

According to Atlas Roofing, an innovator in shingle technology, Core4 outperforms standard styrene-butadiene-styrene (SBS) asphalt for better overall performance on the roof. By adding Core4 to its hip-and-ridge clapboard lines, Atlas is increasing quality and performance expectations across the industry.

Core4 technology, previously only available in the Atlas StormMaster® Shake and StormMaster® Slate shingle lines, consists of polymers that have been enhanced at the molecular level to help shingles withstand the harshest weather conditions. Like StormMaster Shake and StormMaster Slate, StormMaster Hip & Ridge has Scotchgard ™ Protector for permanent protection against black streaks caused by algae.

“With the introduction of our Core4 technology in StormMaster Hip & Ridge, Atlas is reaffirming its commitment to providing the best quality shingles on the market,” said Stan Bastek, vice president of sales and marketing for Atlas Roofing’s Shingle & Underlayment Division. “Our research-driven results show that Core4 technology outperforms standard asphalt technology.”

Introduced in 2019, Core4 contains a proprietary blend of enhanced virgin polymers to create four main features:

  • The PolyCore® technology creates stronger shingles that last longer and have a higher consistency and less variability.

  • FlexCore® technology allows shingles to bend and bend in cold temperatures, especially when others crack and tear.
  • WeatherCore® technology provides shingles with strength and resilience to withstand winds up to 250 km / h and hail damage.
  • ThermalCore® technology promotes shingles stability and reduces the effects of expansion and contraction caused by extreme changes in temperature.

StormMaster Hip & Ridge colors match the Atlas StormMaster Shake, StormMaster Slate and Pinnacle® Pristine Shingles and continue to provide homeowners the breathtaking appeal they have come to expect from Atlas.

StormMaster Hip & Ridge Shingles are now a required component of the Atlas Signature Select® roof system for StormMaster Slate, StormMaster Shake or Pinnacle Pristine installations. StormMaster Hip & Ridge are covered by the Atlas Lifetime Algae Resistance Limited Warranty.
