Asphalt is one of the most popular roofing materials due to its durability cost and versatility, it can however be damages by hail. Asphalt is subjected to other types of wear such as foot traffic, blister rash, or storm damage making it important to be able to distinguish between those types of damage and hail damage.
- Hail damage is visible on the metal flashing bordering the roof. After a hailstorm, the flashing may show a series of dents in the material.
- The area around downspouts and in the gutters may show evidence of mineral granules that have become detached from the asphalt shingles or rolled roofing. Keep in mind, this may be due to hail or from other issues.
- The direction of the hailstorm is another indicator of where the most damage may be apparent on the roof. With an asphalt covering, the area where the granules have been affected the most will expose the shingle substrate.
- The asphalt material may also show signs of round-shaped, tear-drop shaped, or pitted spots where the hail impacted the roof.
- Damaged or bruised shingles, if not replaced, will eventually become water absorbent funneling water to the under layment and decking beneath the roofing material.
- Hail also causes cracks within the asphalt shingles and as time passes, water leakage is imminent.
