How To Identify Hail Damage To an Asphalt Roof:


If you are a homeowner that has recently been through a hailstorm and would like to inspect it for hail damage, the following quick guide will give you a basic understanding of what to look for. 

1. Regular Roof Inspections: If you are willing
to venture onto your roof every spring, it is a
good idea to do annual self-inspections of your
roof to look for any changes since the previous
​inspection and to detect potential issues
​before they become serious.

2. Always Call a Qualified Roofing Inspector:
If you spot a potential issue during your annual
checkup or suspect any sort of wind or hail
damage after a severe storm, you should always
contact a Qualified Roofing Inspector. Many
roofing contractors specialize in insurance
restoration and offer Free Inspections. A trained
representative can discover hidden damage,
separate hail damage from natural wear, educate
you on your findings and make further
recommendations on whether a repair or call to
the insurance company is necessary.

3. Be Careful…How Hail Size Will Affect Your
Roof Inspection

hailstorm and have an idea of the size that fell,
it will give you a basis for what kind of roof hail
damage to expect.Quarter Size HailstoneLess
Than 1 Inch: When smaller than an inch, or
about the size of a quarter, hail can inflict
damage to asphalt roofing. Most often though a
hail damaged roof at this size can be more
difficult to identify. You may require the
assistance of a trained roofing inspector to
accurately identify any hail damage.
1 Inch – 2 Inch: If the size is between 1 and 2
inches, or between quarter and egg size, hail
damage should be more easily found on the
asphalt shingles themselves as well as any soft
metal on the roof.Golfball Size HailGreater Than
2 Inches: Any greater than 2 inches and it will
almost guarantee some level of hail damage to
​an asphalt roof.

Where To Start Looking For Hail Damage on an Asphalt Roof:

When searching for the hail damage to an asphalt roof, look at the following susceptible areas first:

Hail damage to metal roof vent.

Soft Metal: First search for damage to any soft metal on the roof. Check roof vents, skylights, flashing, metal valleys and any other soft metal on the roof. Soft metal damage will not only show signs of hail, but also indicate the size of the hail that damaged the roof.

Ridges: The very peak of a ridge or ridge cap, will take a hail hit directly as opposed to the glancing blows on the main pitched roof slopes. Also due to their location, ridges are more susceptible to damaging hail hits regardless of the direction from which the hailstorm came.

Shingles: Finally look on the shingles themselves. Check not only the interior of an individual shingle, but also the edges where it is weak.

Three Primary Types Of Hail Damage To Asphalt Shingles:

There are three main signs that indicate a hail damaged roof, which include missing granules, bruising and circular cracking. With a basic understanding each, it will help you to accurately identify hail damage and its severity.Hail damaged roof shingle showing granule loss

Missing Granules: Check for missing granules that have exposed the substrate, or black layer underneath them. The substrate exposed should look fresh, or not as if it has been exposed to the sun for an extended period of time. This will indicate new hail damage as opposed to anything preexisting.

Bruising: Run your hand over an individual shingle and feel for dimples or indentations in it. These are an indication of hail hits. Press your thumb against the indentation and examine for a soft spongy feel, like a bruised tomato. This bruising may be hidden, but will cause the shingle to fail prematurely over time.Hail damaged shingles

Circular Cracking: When big enough, hailstones can cause circular cracking around the hit itself in a half-moon or full circle shape. This sort of cracking indicates larger hail and a shingle that has been damaged through to the fiberglass matting, which can make it highly susceptible to water penetration.
