Atlas Core4® Technology

They are designed to Withstand Nature’s Extremes. StormMaster® Shake and Pinnacle® Impact shingles are UL2218 Class 4 Impact rated. The test simulates the speed and terminal velocity of a 2” hail stone falling from the sky. To meet Class 4 Impact criteria, the shingle must show no evidence of fractures or cracks on the backside. Because of their superior flexibility, shingles with Core4® exceed the industry’s standard tear-strength requirement by 50 percent — even in cold-weather installations. Their pliability also means they lay flatter and seal more effectively. Atlas HP42® shingles stay in the roughest conditions — winds up to 150 mph. Your protection starts when the hammer hits the nail. The more comprehensive shingle format and the enhanced Sweet Spot™ nailing area mean your roofer always hits the mark.


PolyCore Technology

This makes shingles with Core4® stronger and longer-lasting than other leading shingle brands. StormMaster® Shake shingles with Core4® are made from enhanced virgin polymers, which means the asphalt core is scientifically engineered to perform better with increased consistency and reduced variability. Because of PolyCore®, Core4® shingles:

  • Protect and extend the life of your roof.
  • Perform better than standard asphalt technology.


WeatherCore Technology

StormMaster® Shake shingles with Core4® Technology come with the highest wind warranty in the industry. Core4® enhanced polymers, and the Atlas double FASTAC® adhesive sealant line create a robust, thermally bonded roofing system. In fastener pull-through tests, which examine the nail’s strength within the Atlas 1 1/2” Sweet Spot™ nailing area, shingles with Core4® performed more than 50 percent better than standard asphalt shingles.


FlexCore Technology

StormMaster® Shake shingles with FlexCore® Technology bend and flex when others crack and tear. Their elasticity is what makes them stronger in two ways:

  1. Better tear strength: These shingles bend and flex, exceeding the industry’s standard tear strength requirement by 50 percent – even in cold-weather installations.
  2. Flatter installation: Shingles that don’t lay flat won’t seal properly during installation. FlexCore® makes them more pliable, which means they lay flatter, seal more effectively, and provide excellent protection for your home.


ThermalCore Technology

During its lifetime, your roof experiences thermal shock or wide variations in heat and cold. StormMaster® Shake shingles are built to mitigate the effects of expansion and contraction due to temperature changes. ThermalCore® Technology also leads to better granule adhesion. Even as the shingles expand and contract, they are less prone to shedding granules. Granule adhesion is necessary because shingle granules protect your roof from the elements. Premature granule loss can lead to accelerated aging, asphalt exposure, and roof deterioration.
