Metal roofing is superior to composition roofing in all types of weather conditions, including hail, sun exposure, and wind. Unlike shingles, metal roofing will not deteriorate due to sun exposure. High winds and/or a hail storm will destroy a composition roof, but a metal roof can handle wind speeds up to 140 MPH and is extremely hail resistant. Metal roofing performs so well, that in the state of Colorado, if you have a metal roof that meets Underwriters Laboratories UL 2218 specifications, you can qualify for up to a 35% discount on your homeowner’s insurance.
