Effects of Hail Damage

Functional hail damage refers to damage that affects the integrity and longevity of the roof.  The severity of hail damage depends on several factors including: type of roofing material, age of roof, roof slope, quality of construction; as well as hail size, hail shape and the velocity and angle of its fall. hail damage roof

Many homeowners are not aware of hail damage on their roofs. Hail damage to roof tops often times cannot be seen from the ground, and that’s a big reason why the idea of hail damage hardly ever crosses a homeowner’s mind.  The Skyline team is trained in spotting and identifying the type of damage that has compromised the integrity of your home’s roof.  Once your roof has sustained this type of damage, eventually moisture will begin finding its way through the plywood decking and eventually into the areas below.

Wind and hail damage to asphalt shingles may consist of punctures, tears, fractures (bruises) or the more common displacement of granules. Displacement of granules occurs when granules have been knocked off by the impact of the hailstones hitting the roof.  The loss of protective granules exposes the underlying asphalt to damaging sun rays.
When asphalt is exposed to the sun, without a protective layer of granules, the shingle becomes vulnerable to UV light degradation, which can accelerate cracking, blistering, algae formation, edge damage and water leaks.

Visible Granule Loss: Some granule loss is common, especially with a brand new roof. With storm damage, granule loss is found in characteristic horizontal lines. This indicates where the shingle seal was broken. Granules rub off as shingles flap in the wind and come into contact with other surfaces.

Damaging winds are classified as those exceeding 50 miles per hour. Winds associated with severe thunderstorms or hurricanes are often called “straight line” winds to differentiate them from tornadoes. Wind damage is associated with more than half of all severe weather events.

Missing Shingles: Shingles that were already cracked or peeling are at major risk of being lost once wind speeds exceed 60 miles per hour. Although roofing manufacturers cover severe winds in their warranty, the estimated wind speed a roof can endure is based on a new, well-maintained roof.
