WeatherCore™ Technology — one of the features of Core4™ Enhanced Polymer Technology — is a shingle’s main line of defense against nature’s harshest elements.

Available in Atlas StormMaster® Shake and StormMaster® Slate shingles, the WeatherCore Technology in Core4 provides durability and strength, giving shingles the power to withstand the damaging impact of hail and extreme high winds.

In fact, Atlas StormMaster Shake shingles come with the highest wind warranty in the industry — up to 150 mph (with special application). And in mechanical uplift tests, StormMaster shingles perform more than 60 percent better than standard asphalt products.
