After a micro tornado hit Roy City, Texas, we snapped to it and started helping homeowners diagnose what had taken place on their roof: if shingles were damaged, if shingles were ripped off and removed. Of course, the three-tab shingles just can't hold up to high winds. These things are typically rated between 35 and 65 mph, which is why we recommend you always get architectural shingle as a minimum. Even further, we recommend Class 3 impact-resistant with a 130 mph wind rating by Owens Corning as our minimum standard.
