Broken Or Exposed Asphalt/fiberglass Mat
Some hail may strike your roof hard enough that it breaks through the granules to the material underneath. If the fiberglass mat or other underlying material is punctured or exposed to the weather, further deterioration and leaks are soon to follow. While this type of damage may cause obvious discoloration, sometimes a cracked fiberglass mat will require a more experienced professional to identify it.
First What Is Hail And How Does It Form
Hail is a type of precipitation that occurs when air updrafts in thunderstorms carry raindrops into the upper level clouds where temperatures are below freezing. A small particle of ice forms around some type of nucleus. It could be a tiny ice crystal, spec of dust, frozen raindrop or something else.
The frozen ice particle then drops within the cloud back below freezing temperatures, where it picks up more moisture from rain drops and water vapor. Eventually it gets caught in another updraft and freezes again.
The stronger the updrafts, the longer a hailstone circulates up and down growing larger and larger until gravity no longer allows it to remain lofted.
At that point, the hail falls toward the ground, where it can inflict damage on people or property.
Impact Of Hail Damage
There are two categories of hail damage: cosmetic and functional. Cosmetic damage doesnt affect a roofs ability to function properly. Functional damage is more serious and impacts a roofs integrity and longevity. Your roofing contractor will be able to determine whether the damage to your roof is functional or cosmetic so you can relay the correct information to your insurance company.
Even if the damage seems minor, like missing granules across your roof, it can turn into a larger problem later. Missing granules can leave areas of your roof exposed to the elementslike harmful UV rays that can fade and deteriorate your roof over time and lead to water leaks. If not dealt with soon enough, even small amounts of moisture that make their way under shingles can encourage mold or rot and bring your roof problems inside your home.

What Do I Do If I Think I Have Hail Damage
If youre a homeowner and think you may have hail damage, the first thing you should do is for a free roof inspection.
If the inspector thinks you may have damage, your next step would be to file an insurance claim with your homeowners insurance company. Your insurance adjuster will put together an Xactimate estimate.
A lot of people ask: Will insurance pay for a new roof? This depends on your policy and who you have on your team. A trained professional can determine whether the damage is functional or cosmetic in nature. A public adjuster can help you negotiate a fair deal with the adjuster.
Homeowners: Its very important that you have your contractor come out and inspect the roof with your insurance adjuster. You have to remember the insurance company is looking for reasons NOT to replace your roof. Thats why its important to make sure your contractor inspects the roof with the adjuster.
How Hail Damages Your Roof
The severity of roof hail damage typically depends on the size of the hail, wind speed, and the material of your roof. With enough force, hail impact can shatter roofing materials like clay or concrete. Lets look at a few common ways hail can damage your roof and how each one of them may affect your home.

Functional And Cosmetic Damage
Generally speaking, there are two types of damage to consider: Functional damage affects a roof’s structural integrity, and cosmetic damage harms a home’s visual appeal.
Cosmetic damage may only be a small chip or dent here and there, but functional damage to shingle roofs can include tears, fractures, punctures or the loss of granules from the surface of asphalt shingles. When granules are lost, the underlying asphalt becomes susceptible to long-term weathering from the sun’s UV rays. This may lead to blisters and cracks, as well as water leakage.
How To Tell If You Have Hail Damage From The Safety Of The Ground
I dont recommend for anyone who doesnt know how to walk on a roof safely to check for the damage mentioned above. Theres no reason to put yourself in danger when your insurance company sends someone out to check it.
But I understand wanting to do your due diligence before filing an insurance claim. Below is a list of things to check for visible hail damage from the safety of the ground:
- Dings or strikes to your garage door
- Holes in your window screens
- Dings to any painted wood or shutters
- Splatter marks or dings to your electric meter, AC unit, or grill
- Dents to your mailbox and other soft metals on your property
- Dents on the top of your car and the cars hood
This list doesnt mean your roof has extensive hail damage. It just gives you an idea if you should contact your insurance company and file a claim.

The Insurance Process Is Muddy And Confusing
Both the roofing industry and the insurance industry dont have the best reputation. The unfortunate truth is that there are a lot of roofing and insurance companies who don’t necessarily have your best interest in mind.
Thats why we like to say the insurance process can be muddy and confusing. Some companies use this to their advantage and scam homeowners who are desperate to get their roof problem taken care of.
Thats not to say that all roofing or insurance companies are out to take advantage of you. All Im trying to do is let you know that there are people on both sides who unfortunately try to take advantage of people in a stressful situation.
Understanding this from the beginning helps you be aware to ensure something like this doesnt happen to you.
Question: Insurance Company Says Shingle Defect Gaf Says Hail Damage
We’ve been told by that this is the result of manufacturer defect. We filed a warranty claim with GAF and they claim their lab results indicate that the shingles are still up the MFG spec and this is hail damage.
They will not cover this under warranty. I’ve been told by 3 separate people that they’ve never seen shingles this bad before and that this is a serious defect.
It was brought to my attention by an adjuster that even if this was a defect the hail damage is a subsequent loss and should still be covered under the ensuing loss clause in our policy. – J.F. 8/12/14
Reply: inconclusive photographs of roof shingle granule loss: sorting out hail damage from shingle defect, possible role of shingle blistering
I looked at your photos with interest, though there was not enough information for me to have a confident opinion.
I saw what looked like fragile edges to the bald areas where granules were lost that could indeed suggest recent hail damage and granule loss.
But I also saw weathering of the exposed shingle substrate black asphalt-filled surface that would have suggested old granule loss. Then I re-read in your note that the hail storm occurred last April.
If your photos of April believed-hail-damage were taken in August, about 4 months later, possibly the whitish weathering I saw occurred on the exposed shingle substrate during that interval.

Introduction Of Hail Damage To Asphalt Shingles
As humans came into this world, at first, they started living in caves made from Rocks. The primary intention for living in caves was to protect themselves from adverse environmental conditions such as rain, storm, wind, etc and also, to protect themselves from the attacks of wild animals.
Although caves fulfilled their primary intention, humans with their developing brains, soon realized the need for more.
They eventually grew aesthetic and architectural sense, and also the need for permanent belongings. As caves were not able to fulfill that, humans started thinking of building their own homes rather than living in caves.
So, they started gathering materials and started building homes using their concept. With progressing time, the homes they have built soon started facing various challenges.
As the primary material for construction was Wood, many a time, then the fire broke out in their house , while in some other times, the wood easily decayed due to presence in moisture, which as well as indirectly responsible for the growth of insects.
Thus, facing such challenges, the construction materials evolved as well. With the time of evolutions of construction, the concept of asphalt shingles is coming. There has a controversy arises that how asphalt shingles are damaged by hail and actually what hail damage looks like.

In the asphalt roof shingles, how many granules are removed on the affected area thats affect the water-shedding ability or the service life of shingles, this process named by the author is a granule loss study on asphalt shingles?
With a wire brush, the quantities of removing granules are varying from new glass-fiber and three-tab mat shingles. After that for ten years, for the weather conditions in Texas and Dallas, the asphalt shingles are exposed naturally.
Approximately, 5, 15, 45, 70 % of granules are removed from the total amount of granules of the asphalt shingles. An upside-down shingle was installed when by the weather the asphaltic mat was exposed.
On the south-facing over wood conventionally the asphalt shingles were installed on a 4:12 pitch. AtAfterhe the study at intervals of ten years period the shingles were examined as well.
The exposed asphalt, in one year, had oxidized grey but on the surface of the shingles has no visible evidence of crack or erosion. The shingles to shed water after five years have oxidized of the exposed shingles area but the functions of the shingles did not affect.
Without granules shingles, surface erosion was visible on the shingles and the other hand had become glass fiber had become exposed. Without granules, after 10 years in the shingles, no significant change was noted. Due to erosion, the life longevity is a decrease of the asphalt shingles.

Question: Phoenix Hail Storm
There was a hail storm in Phoenix, AZ, in October 2010. I was out of the country at the time. I have returned in April 2012. I am in the process of determining if there were hail damage on my roof currently.
The insurance inspector claim there was no hail damage on the roof except on the AC condenser and some of the window screen. The inspector claimed the damages seen on the roof were mainly due to weather and acid from the bird dropping. Is is possible for me to send some photos to you to obtain your opinion? Thank you in advance for your time and help in this matter. – PSF Chan 5/24/12
Bird droppings are not likely to produce a shingle scouring / granule loss pattern that would in the slightest be mistaken for hail damage. Even if we buy the “acid damage” claim the birds would have to poop uniformly over an entire roof and the effect would have to be granule loss without remnants of guano.
I’d like to see some sharp photos both of the whole roof, all slopes, and of the slope where the damage seems apparent to you, and sharp close ups of the shingle damage area details. Use the CONTACT US link found on any website page.
