Atlas StormMaster shingles (particularly the StormMaster Shake line) are evaluated by professional roofing contractors as exceptional, elite-tier architectural shingles. Built with a rubberized SBS polymer-modified asphalt core using FlexCore technology, they achieve an official UL 2218 Class 4 impact resistance rating, withstand extreme winds up to 150 mph, and resist thermal cracking. Their superior storm defense and long-term durability make them an outstanding investment.
