What is an Impact Resistant Shingle?

Impact resistant shingles can withstand impacts from flying objects to a much greater extent than a common asphalt shingle. The impact resistant rating system ranks shingles’ resistance to impact into 4 levels – 1 through 4, with Class 4 as the highest rating level to impact resistance. The Atlas, the StormMaster series of asphalt shingles are rated as a Class 4 per the ASTM D2218 Test Standard and insurance companies in many parts of the US actually discount premiums when the StormMaster shingles are installed in place of regular asphalt shingles.
