No matter how large the hail that struck your home's roof is, you could have hidden damage. All hail has the potential to cause shingle delamination and other problems that, if not addressed, can cause roofing problems relating to the structure and integrity of your home. As soon as possible, you should have your roof inspected by a professional roofing company and take temporary repair measures to prevent further damage. Hail damage can range from large, highly visible dents and tears to almost undetectable indentations or unnoticeable granule damage. Even small amounts of damage can compromise the integrity of the roofing system, leading to the deterioration of the shingles months later.
Outward damage to a roofing shingle typically compromises and affects the underlying shingle layers to some degree. The hail impact may damage the roof, thereby affecting the granular surfacing in the asphalt shingle top coating. This loosens the granules, potentially allowing them to separate from the coating layer and wash off of the roof. Without the granule surfacing, ordinary sunlight exposes the asphalt top coating to ultraviolet radiation, which eventually deteriorates, exposing the underlay and potentially causing a leak.
