Northern Colorado's open plains and the Cheyenne Ridge convergence zone make Longmont a frequent target for large hail events. Several storms in recent years have caused widespread roof damage across the area. Signs you might have damage include dented gutters or downspouts, chipped paint on window frames, and damaged outdoor furniture or AC units. However, most roof hail damage is invisible from the ground. The only reliable way to know is a professional inspection from on top of the roof. Gates Enterprises provides free hail damage inspections for Longmont homeowners with no obligation.

James Hardie fiber cement siding is our top recommendation for Longmont. It handles Colorado's UV radiation, temperature extremes, and hail better than vinyl or wood. It carries a Class A fire rating, which is increasingly important in Colorado. It also holds paint well at altitude where UV degradation is more intense. For Longmont homeowners who prefer a different look, we also install premium vinyl and wood siding options.
