Got Questions?

Hail has always been known to ravage roofing systems; yet, it can be tricky to diagnose damage. While every hailstorm has strong potential to compromise your roof’s structural integrity, seeing no evidence might lull you into a false sense of security.


To keep
hail damage from going under your radar, Viking Contractors suggests looking for these red flags:


Dented Metal Components

Regardless of malleability, any metal can sustain indentation upon the impact of high-velocity hailstones of any size. Minor denting can be hard to spot from the ground, but an eyeball test can reveal major dings in gutters, downspouts and pieces of flashing. They can pose serious structural issues, especially when hailstones begin to melt and pool in the affected areas.


Bald Spots

The force of hailstones can dislodge the protective granules of asphalt shingles. Any experienced hail
roo expert would say that the gutter system holds proof of granule loss. Knocked-out pieces should’ve collected either in the gutters or on the ground near downspouts.


Popped Blisters

The hail might be too weak to displace shingle granules, but it could be powerful enough to pop prevailing blisters. Blistering happens when moisture has accumulated within shingles during their manufacture or because of an overheated attic. Hail-popped shingle blisters would normally show uniform damage, especially on the same slope, because of the storm’s wind direction.


Fractured Shingles

Specialists in
hail damaged siding restoration and roof repair would attest that abrasion within the shingle mat represents the worst-case scenario. Bruises to the base of asphalt shingles create gaps for water to seep into the underlayment. This is where leakage begins so it must be addressed sooner than later.
