Metal roofs are made of strong metals including tin, aluminum, zinc, copper, and steel. They’re more durable than asphalt shingles, so they have longer life spans. Metal roofs can withstand extreme weather such as heavy snow and radiant summer heat. They can even endure winds of up to 140 mph. These roofs are sturdy—especially the steel ones, which score on the higher end of hardness scales. Most metal roofs have a Class 4 impact resistance rating, meaning they can withstand hail up to 2 inches in diameter.
