Does hail cause granule loss?

Does hail cause granule loss?

Even small hail can dislodge granules from older shingles. This is especially true when hail is accompanied by heavy rainwater runoff. Heavy runoff can erode loosened granules. Shingles less than six months old can experience a lot of granule loss, although this early granule loss does not expose the asphalt.

Does hail crush granules?

Hailstones do not crush granules when they strike asphalt shingles. Instead, hailstones typically remove granules from the sides of the impact and force granules toward the center of the impact, deeper into the asphalt layer. The granules were pressed further into the asphalt, but not crushed.

What does granule loss look like?

Granule loss which is uniform across the roof is usually a result of normal weathering. Over time, the bond between the granules and asphalt deteriorates, and granules will be loosened and carried away by runoff. The blistering is probably old, judging from the grey color of the exposed asphalt.

What is the percentage range roof manufacturers state is the total weight of granules to the total weight of the shingle?

Generally, about one-third the weight of an asphalt shingle is granules such that a 25 square roof covered with three-tab shingles would have about one ton of granules.

What is the difference between blistering and hail damage?

Occasionally, damage from hail is mistaken for damage from blisters. Blisters are caused by the expansion of volatile gasses escaping from the asphalt layer. Blisters leave steep-sided pits or pockmarks that are usually missing some asphalt material. Sometimes, enough asphalt is missing that the mat is exposed.

What is hail damage to shingles?

Hail damage to asphalt shingles may consist of punctures, tears, fractures (bruises) or the more common displacement of granules. The loss of protective granules exposes underlying asphalt to damaging sun rays.

What happens when hail hits shingles?

Cracks in the shingles Hard hail impacts or high winds can grip the shingles and cause cracks. This can lead to exposure and tears, leaving your roof with bare spots. Cracked shingles cannot effectively protect your roof from the weather.

Is granular loss bad?

Granule loss is a regular occurrence, but it is a cause for concern when you spot more granule loss than usual. Missing granules can mean many things, but the worst is defective or aging shingles that can’t defend your home against harsh weather conditions effectively. While not common, this does still occur.

Why is granular loss on a roof bad?

Aging Roof Losing Granules Naturally, that means the weather and sun exposure will cause your roof to lose its flexibility and shed some of the asphalt roofing granules covering it. Asphalt shingles should experience fairly gradual, even-spread asphalt shingle granule loss, and this is not necessarily a bad sign.

How much does an average roof weigh?

A bundle of three-tab asphalt shingles weighs between 60 and 80 pounds, but this may vary depending on the quality and type of shingle. Generally, three bundles of shingles are enough to cover 1 square of roof (100 square feet), which can weigh anywhere from 180 to 240 pounds.

How many bundles of shingles do I need for 2000 square feet?

60 bundles
The number of bundles or squares you need will depend on the surface area of your roof, and its pitch or slope. For example, a 2,000 square foot roof will require 20 squares or 60 bundles.

When should hail damage be replaced on a roof?

If you believe you’ve identified roof damage or you’re unsure whether there is damage, then you may want to contact a professional to inspect your roof. Ignoring a minor problem may lead to a much bigger, more expensive problem later. If your roof leaks following a hail storm, you may need to replace it altogether.

Can a hail storm cause granule loss on shingles?

Hail impact is not the only element that can cause granule loss. Normal rainfall, wind or temperature change, and even foot trafficking can cause granule displacement from a shingle. It is true, after a heavy rain or hail storm, an abnormal amount of granules may be collected in the gutter system.

What kind of damage can hail do to a roof?

Hail damage to your roof in the form of torn shingles, missing shingles or dented shingles. Broken windows. Hail damage usually causes severe damage to your trees, shrubs and the plants in your yard. Damage to your car. If there’s readily apparent hail damage to your home make any emergency repairs first.

What causes granule loss on asphalt roof shingles?

Granule loss is expected from the moment shingles are manufactured, shipped, installed, and during the weathering process. Granules are part of the wearing surface on the shingle and exposure to hail is part of the wearing process that is actually built into the design.

How to file a claim for hail damage?

Contact your agent and file a claim with your insurance company. Your agent will set up a hail damage claim file that contains the claim number, the name of the claims adjuster assigned to your claim, and any contact information such as phone numbers and e-mail addresses that will be helpful throughout the claim process.
