Blistering Vs. Hail Damage on a Roof

This video shows you the difference between blistering and hail damage on a roof. Blisters are now usually formed when volatiles flash out of the asphalt in newly installed shingles. This is caused by excessive heat from poorly ventilated and over-heated roof systems. Even though blistering is often perceived as a manufacturing defect, it's usually caused by poor ventilation of the roof system. Hail is random damage with no discernable pattern. Hail hits that are black in color. Loss of granules, which may expose the roof felt. Asphalt and/or mat that appears shiny. Hail hits that are soft to the touch, like the bruise on an apple.

A lot of people mix up blistering and hail damage and we hope this helps you distinguish between the two!
