Thus more granules are initially placed on the shingles than needed to cover the mat.
Hail granules pushed into shingle mat.
Granules are part of the wearing surface on the shingle and exposure to hail is part of the wearing process that is actually built into the design.
Granules are what provide the coloring to shingles and they also protect the shingle s asphalt from degradation that would occur from prolonged exposure to uv light.
Bruising is the next thing the adjuster will check.
Hail impact is not the only element that can cause granule loss.
Fractured fiberglass mat which may or may not be immediately visible.
The small area usually exhibits the shape of a tool or other hard object.
Roof shingle granule loss may be normal shingle wear hail damage wear or defective roofing product as we explain here.
These other damages may be mistaken for hail damage by someone poorly trained and or the inadequately experienced.
Cracks may be present especially if high winds blew the shingles back.
A fractured mat may result in tears radiating out from the points of impact.
Functional hail damage to asphalt shingle roofs is characterized by a localized loss of granules usually circular in shape and a fracture in the mat.
This bald asphalt shingle roof is way past needing replacement and is almost certainly leaking.
The page top photograph shows severe loss of mineral granules from an asphalt shingle roof.
Mechanical damage mechanical damage to a shingle is evidenced by a small area of granules being pushed into the asphalt and or the mat.
When asphalt shingles are manufactured colored granules are blended and then rolled into the dark substrate.
Granules are part of the wearing surface on the shingle and exposure to hail is part of the wearing process that is actually built into the design.
Following is the third list of four damages effected by other means.
Either way the adjuster will be able to see the exposed substrate.
A fracture in the mat is evidenced by a visible relatively clean fracture an indentation in the mat of the shingle and or localized softness in the mat.
Hail can cause the granules on shingles to loosen or fall off exposing the fiberglass mat underneath and causing it to breakdown from exposure to the sun and other elements.
It is true after a heavy rain or hail storm an abnormal amount of granules may be collected in the gutter system.
Normal rainfall wind or temperature change and even foot trafficking can cause granule displacement from a shingle.
Thus more granules are initially placed on the shingles than needed to cover the mat.
