Irrespective of their longevity, steel and aluminum roofing products cost three to four times as much as asphalt shingles. To conform to the International Residential Code, the State of Texas Department of Insurance Windstorm Inspections regulates that roof shingles must carry either an ASTM D3161 Class F rating or a UL 2390 Class H, both of which indicate a product that can withstand gusts up to 130 mph. Within this directive are listed more than 200 types of shingles, made by six manufacturers, all of them in compliance with the standard.
