Storm damage to roofing

What does the damage look like?

Wind Damage

The most obvious wind damage to shingles occurs when the shingles are flipped over or torn off the roof. Less obvious damage is when the wind lifts the shingles and lets them lay back down. If the shingles are getting a bit older, the top edge of the tab will crease and shed granules, leading to short-term failure.

Creased Shingles

Depending on the composition of the shingle, some are more susceptible to damage than others. As the roof ages and the shingles become more brittle, it's easier for the wind to get under the shingle and break the seal loose. Once that happens, it's just a matter of time before they will raise up, crease, flip over, and break off.




Hail Damage

There are many factors that influence hail's effect on roofing shingles. The age of the roof, the condition of the roof, the size of the hail, and the direction of the hail.

As a roof ages, it becomes brittle and shrinks to some degree. As hail strikes an older roof, the likelihood of granules becoming dislodged is significantly higher than if the roof was a few years old and still was soft and pliable. This a normal condition and does NOT constitute hail damage. Shingles are expected to lose granules as they age.


Size Matters

The larger hail becomes, the more likely that it will cause fractures in the underlying mat of the shingle. This is what most insurance companies are looking for, a physical puncture of the shingle. It is very difficult for hail to damage a shingle unless it is in excess of 2 inches in diameter.
