Storms happen, and having a Pinnacle® Impact roof means one less thing to worry about. These shingles meet a Class 4 impact rating, the highest available for asphalt shingles, and a wind warranty of up to 160 mph.* Add in 3M™ Scotchgard™ Protector to help prevent algae growth and 3M™ Smog-Reducing Granules to help clear the air, and your roof isn't just protecting your home, it's taking care of it.
