If a large hail storm has recently passed through your area, you are going to want to get outside and inspect your roof to ensure that it wasn't damaged by the hailstorm. Here are the three things that you need to look for when inspecting your roof to see if it sustained hail damage in the most recent storm.
One of the first things that you are going to want to look for are shingles that have been bruised. Like skin, when shingles are hit by strong pieces of hail, it can create bruises on the shingles on your roof. The bruises are generally around the same size as the hail that was released in the storm. For example, if there was one-inch hail in the most recent storm, there is more than likely going to be one-inch bruises or if the hail was a big as a baseball, the bruises will be too.
The bruises on the shingles may be visible to the naked eye. However, you may have to touch the shingles in order to really feel the bruises, as you may not be able to see all of them. When you touch a bruise, it may have a slightly springy feel to it.
The second thing that you want to keep an eye out for are cracks. Sometimes, in addition to bruising your shingles, strong hail can actually cause cracks to form in your shingles. These are generally not straight or jagged cracks; instead, the cracks are circular in shape. Hail storms are one of the few things that cause circular shaped cracks on your roof shingles, making it easy to identify this type of damage as hail damage.
The final thing that you want to look for are loose or missing granules. A strong hail storm can actually remove the granules from your shingles. When a strong piece of hail strikes your roof, it can remove all the granules from an area on your shingles, allowing you to see the the black substrate under the granules on the shingles of your roof.
You can also check the gutters on your roof to see if there are granules in them. If there are, that is a strong sign that the storm removed these granules and not general wear and tear to your roof.
Remember to take pictures of all the damage that you spot, and send these pictures to your insurance agency so that they can help pay for the cost of repairing your roof. Companies like Stevens Roofing Corporation can then help you with the repairs.
