It seems that hail storms can go relatively unnoticed unless they are violent, with hailstones the size of a baseball or more. Fortunately, the majority of hail storm are not so destructive. Nearly ninety percent of hail storms are comprised of hailstones that are golf ball sized or less. However, homeowners need to be vigilant when it comes to monitoring hail storms. Smaller hailstones may not fracture roofing shingles nevertheless, damage can still occur. Hailstones of any size van compromise and damage asphalt shingles by knocking off their granular covering. Once sufficient granules have eroded, the asphalt is exposed. Eventually, sunlight deteriorates the asphalt and the shingles will not prevent leaks in the roof.
Roofing standards to the rescue
Roofing manufacturers have consistently improved shingle design and construction. The first improvement was to create asphalt shingles that are more wind resistant. This is important because many hail storms are a by-product of severe thunderstorms with high winds. Roofing manufacturers have also designed an asphalt shingle that is significantly more impact resistant, rendering roofs with these specialized shingles significantly more resistant to damage related to wind and hail.
Defining impact resistance
Standards have been established for impact resistant roofing shingles. Materials are rated from Class 1 through 4, based on their resistance to impact by testing with steel balls simulating 90-mph hailstones of varying size. A Class 4 rating is the strongest. These specially rated asphalt shingles are stronger and more flexible than standard shingles. This rubber-like quality resists fracturing of the fiberglass mat, preventing premature deterioration. The increased flexibility also makes the shingles more wind resistant.
Class 4 rated products have been available for many years, but they were made of aluminum, copper, and resin shingles. Consequently, they cost considerably more than standard asphalt shingles. Although impact resistant shingles cost more initially, they are comparable in price over the lifetime of the roof. Homeowners who install them realize significant reduction of roofing maintenance costs and possible increase to their home resale value. With the introduction of impact resistant asphalt shingles, roofs can provide greater wind and hail resistance at a more affordable cost. Every year, thousands of homeowners lose their roofs to hail storms and wind damage. It has been proven that Class 4 materials can offer long term roof protection for homeowners in the Charlotte and Concord areas.
