Q: What size hail is damaging to roofing? A: This depends on several variables – shape, hardness, & density of hail, wind speed, age, and type of roof. In general, pea and marble size hail should not damage composition shingles in good condition, unless extreme winds are present. Q: You noticed granules from your composition roof in your gutter and driveway. Is this normal? A: Yes. With composition shingles, granular loss is a part of the normal weathering process. Small hail impacting a roof often displaces some of the granules as does rain, wind and foot traffic. Q: You noticed lighter colored “splatter” marks on your roof after a hailstorm. Is this damage? A: No. The “splatter” marks that you see are normal after a hail storm. Your roof has darkened over time since its installation as a result of algae and oxidation. When the hailstones contact the roof, the algae and oxidation are removed, leaving a light colored mark. In time, these marks will fade as algae grows and oxidation continues on your roof. Q: Are all homes in a neighborhood affected the same way by hail? A: No. The number, size and hardness of hailstones can vary tremendously within a small locality. Other factors include velocity and direction of the wind, roof pitch, age and condition. Each roof is different.
