As most homeowners in Colorado know, our home exterior products have to work a lot harder to deal with the extreme heat and cold that we experience in Colorado, not to mention the frequent hailstorms that we get. Because of that, you should install impact rated roofing and siding materials. These products, in addition to giving you extra protection against hail damage, often result in lower insurance premiums. Use Class A Fire rated shingles and class four impact rated shingles.
