Does Your Roof Have Hail Damage?

If your asphalt shingle roof has been hit by hail, how can you tell whether your roof has suffered hail damage?  The answer to this question is that roof hail damage is not always obvious.  Large, golf ball sized hail will cause damage that is easy to see but smaller hail can cause damage to an asphalt shingle roof that is not as clearly evident.

First, It’s important to understand what hail damage to an asphalt shingle roof is.  For really large hail, damage includes bruised, cracked, split, and broken shingles.  This type of hail damage is easily apparent to even the most casual observer and can be seen from the ground.  There is no question that the roof will need to be replaced.

Smaller hail causes more subtle damage that is harder to see but may still require a roof replacement.  Asphalt shingles are covered with a layer of ceramic granules that give the roof color and texture, but most importantly these granules protect the asphalt from the harmful rays of the sun.  Without this layer of ceramic granules, an asphalt shingle exposed to the sun would dry out in a few months and fail.

Marble sized hail and larger is capable of dislodging some of the ceramic granules from an asphalt shingle.  If a significant percentage of the protective ceramic granules have been knocked loose by hail, the roof may look OK to the untrained eye and will not be leaking, but a few months down the road the sun damage will cause the roof to fail.

An experienced roofing contractor or roof inspector can identify this type of hail damage.  Most good roofing contractors offer free roof inspections so if you even think your roof may have hail damage, it’s a good idea to have the roof inspected.
