Hail Damage

Hail Damage to Your Roof

The spring and the summer months are notoriously known for severe storms. These storms can cause a lot of damage to your home. Often times, homeowners and business owners may not even know that they have damage to their home. It is recommended that if you live in an area that is repeatedly hit by severe storms with large hail that you check your roof often. By checking your roof regularly, you may find spots that could ultimately ruin the inside of your home. A leaking roof is caused by hail damage 35% of the time.

Hail can do a lot of damage to a roof without the homeowner every knowing. You will not be able to see the damage from the ground. This is why most damage goes unnoticed. Most people are expecting to see damage just by looking up at the roof. There are many people that think unless you have shingles missing, you are going to be okay. That is not the case with hail damage.

Inspecting your roof for hail damage is relatively easy if you know what you are looking for. If you notice any spots on the shingles that look like dimples or parts of the shingles are missing, then this could be hail damage. Dark spots or indentions are likely to from hail damage as well. If you think that you have hail damage, you will want to call your insurance adjuster to come do an inspection. Repairs for hail damage are normally covered by your home insurance.

Generally, hail must be 1 ¼ inches in diameter (Half-Dollar size) before it causes damage to heavy composite shingles or wood shake shingles. Lightweight composite shingles may show damage after being struck by 1-inch diameter (Quarter size) hail. Only deteriorated composite shingles will show hail damage due to hail less than 1 inch in diameter, and the hail generally must be more than ¾ inch in diameter (Dime size).

If your area has received hail large enough to possibly cause damage to your roof, you may want to examine other objects at ground level before calling your insurance company or pulling out your ladder. Hail strong enough to damage a roof will also cause damage to nearby cars, wood fences, shutters and/or exterior siding. Also a significant amount of shingle granules appearing at the end of downspouts may indicate potential damage; however, granule loss, in and of itself, does not prove hail damage.

An inspection of the roof can reveal other causes that could have led to damage. There are certain types of damage to consider before assuming you have hail damage:

Embrittlement/Hardening – Each composite shingle has four layers: a mat composed of glass fibers or organic materials; asphalt; a filler made of sand and limestone; and granules made of crushed stone with a ceramic coating. When the shingle is exposed to the weather, the asphalt will deteriorate and shrink. The shingle will harden, become brittle and may demonstrate one or more of the following phenomena:

Cupped or Curled Edges – As the outer edges of the shingle shrink at a faster rate than the interior of the shingle, the edges tend to curl up or down.

Craze Cracks – These are hairline cracks that appear in a random pattern throughout the shingle.

Horizontal, Vertical or Diagonal Cracks (also known as Splitting) – Caused by asphalt shrinking at opposite ends of the shingle. As these ends shrink, the middle of the shingle pulls apart, leaving a crack (split).

Splices – Occasionally, a shingle is created at the place where one end of a roll of mat ends and the new roll begins. The splicing together of these rolls leaves a double thickness of mat that does not allow the remaining layers of the shingle to be properly formed.

Blisters – Heat causes the asphalt to release gases, which sometimes are trapped by the surrounding layers. The resulting blisters can then “pop,” and leave pockmarks in the shingle. A blister does not have the characteristic “bruise” that can be felt in a shingle that was struck by a hailstone.

Discolored Streaks or Patches – Lichens or algae can grow on shingles in most weather conditions. The colors usually seen are green, brown, orange, gray, or a mixture of those colors.

Diagonal Pattern of Deterioration – If you see a diagonal pattern of shingle deterioration or color gradation appearing across three tabs of shingles, it generally is a result of a manufacturer’s defect in the shingle. The diagonal pattern shows up as a result of the pattern that was used by the roofer when installing that batch of shingles on your roof.

Rounded or Horseshoe Shaped Areas – These areas, where the granules are compressed into the coating asphalt, and the granules themselves appear to have been crushed to a powder, are caused by hammer damage. Such damage usually occurs near ridges.

Hail damage will result in a random pattern of strike marks in various sizes. If you can see a pattern to the damage, it was not caused by a random phenomenon like hail. In addition, hailstones will leave a “bruise” in the mat, which your fingers can usually detect in and around the crater.

If, after surveying the damage, you believe you have a hail claim, call your insurance company or agent. An adjuster will be sent out to consider the nature and extent of the damage. Depending upon the circumstances, the adjuster may or may not require your physical presence to review the damage. Therefore, you may wish to prepare a written list of items which also appear to be damaged (i.e., windows, shutters, siding, fascia, ceilings, satellite dishes, etc.) for the adjuster’s consideration.

You are responsible for taking any steps necessary to prevent further damage to your property after the hailstorm. If the necessary repairs must be done before the adjuster can personally inspect the damage, videotape or take good quality photographs of the damage. Retain damaged items such as carpet or furniture for the adjuster to examine before discarding them.

If you have not already done so, find your insurance policy and become familiar with it. You may find that you have additional coverage you had forgotten about. Make sure you also are aware of what the policy requires you to do. And, double-check the policy’s exclusions, so you will know what is not covered by your policy.

In addition, if you have personal property to be replaced, try to find as many receipts as you can, in order to determine how much you paid for those items.

After inspecting the damage, the adjuster will prepare an estimate of the cost to repair your roof. Depending upon the nature and extent of damage, your adjuster may recommend repair or replacement.  In addition, check your policy’s deductible.

If, after obtaining estimates from roofing companies, you find the adjuster’s estimate lower than the roofers’ estimates, let your adjuster know. There may be differences in materials or damage that he or she can explain or resolve for you.
