As the DFW metroplex moves through the peak of the storm season, many homeowners are dealing with the aftermath of localized hail events. While large stones cause immediate leaks, smaller, high-velocity hail often causes 'bruising' that is not visible from the ground.
Bruising occurs when the impact displaces the protective mineral granules from the asphalt layer. This exposes the underlying bitumen to ultraviolet radiation from the Texas sun. Over time, the sun makes these spots brittle, eventually leading to premature leaks even if the roof survived the initial storm.
Key Inspection Points
- Loss of protective granules in gutters and at downspout exits.
- Circular patterns of missing granules on the shingle surface.
- Soft spots or indentations in the metal vents and flashing.
Property owners are encouraged to document these surface changes early. If granule loss is significant, the lifespan of the roof can be reduced by several years, making a timely insurance assessment critical for long-term protection.
