Knowing how to identify what type of damage has occurred on your roof can make all the difference, especially for the majority of insurance companies that cover hail damage but not roof blistering. Let’s take a look at how you tell the differences between roof blistering and hail damage.
Roof Blistering
Roof blistering occurs when shingles develop raised dimples on the surface. This is a direct result from either improper manufacturing, installation, or wear and tear. It is a natural progression in the lifespan of the shingles, yet blistering should not happen during the warranty period.
After an extreme weather event has occurred, blistering can be much tougher to accurately identify. For instance, the blisters can be mostly popped when struck during a hail storm. This can oftentimes resemble the pockmarks of hail striking your roof. One slight visible difference is that popped blisters do feature a small raise around the divot where the blister formed.
Hail Damage
Hail results in divots around your shingles, with some spots appearing bare where the granules have been knocked away. There will be no visibly raised area around the pivot, simply a few missing granules and dents found in the substrate material of the shingle.
While hail damage can be difficult to spot from a distance, this is a serious issue no matter what. Damaged shingles can fail much earlier than expected. This can allow water to get to the roof’s wooden structure, causing indoor leaks.
What Are The Differences Between Roof Blistering And Hail Damage?
The impact of hail can ultimately decrease the lifespan of your roofing system. Shingle blistering is a condition that results from old age or faulty manufacturing/installation. Both of these damage types can look similar.
Hail storms can pop most blisters, leaving behind small craters that look like divots on your roof. The difference between the two matters a lot to most insurance companies, as there is no coverage for blistering. Most insurance companies do cover hail damage, however.
To accurately identify the damage type, homeowners should check the vent covers and flashing for dents caused by hail. Also check the gutters to see if any hail is still there. A few unpopped blisters should be present, as hail is unlikely to pop each and every blister on a roof.
