As part of the legendary Hail Alley, this region is one of the most hail prone areas in the world. On average, local homeowners and commercial building managers deal with an average of three to four catastrophic hail events each year. One recent hailstorm caused damage worth more than $767 million to area buildings and property. With weather like this, it's important to keep homes and buildings as safe from hail damage as possible.

One of the best defenses against ruinous hailstorms is an impact resistant roof that weathers even large hail stones that travel at high velocities. It's also important to have an impact resistant roof installed by an experienced Denver roofing contractor with expertise in local area building codes and weather patterns.

With hail damage causing hundreds of millions of dollars in damage each year, the roof manufacturing industry has met the challenge to produce roofs that are better able to withstand the impact of hailstones. As a result, homeowners can choose from impact resistant asphalt shingles, tiles, slate and metal panels whose advanced features make them less prone to damage.

Part of this newfound hail resistance comes from engineered, synthetic materials. Impact resistant shingles often contain modified polymers like SBS that make them better able to withstand pressure.

These shingle roofs are also laid over new thinner, more resilient underlayment to improve shingle performance. Synthetic tiles use resin, rubber or plastics to make them more impact resistant. A roof that is steeply pitched is safer during a hailstorm than a more gradually sloped roof, and sturdy tongue in groove decking also creates a more hail ready roof.

In most cases, homeowners and building managers should look for roofs that offer Class 3 or Class 4 impact resistance. These classifications are determined by rigorous testing of the roof by one of two laboratory standards.

Underwriters Laboratories provides impact standards through its UL 2218 testing, which drops increasingly large steel pellets onto roofing from varying heights. Usually used to evaluate the impact resistance of flexible roofing like asphalt shingles, UL 2218 drops a steel ball onto the roof in the same spot two times, beginning with a steel ball that is 1.25 inches in diameter.

FM Global also provides similar testing under its FM 4473 standard, but these tests actually shoot frozen ice pellets at the roofing. In both instances, Class 3 roofs can withstand impact from 1.75 inch pellets, and Class 4 impact resistant roofs hold strong against two inch spheres.
