Asphalt roofs hold up well to rainfall and most hail, but they do not hold up well to large hailstones. You might not see the effects of hail damage right away, but it is better to catch hail damage early before a leak develops. Fixing hail damage depends on what kind of damage you have, so after a hailstorm, you will want to inspect your roof. Knowing what to look for will help you in making repairs.
Different Types of Hail Damage
If you don't know what to look for, hail damage can be hard to spot, but once you know what hail damage looks like, you can stop leaks before they form. Here are some common signs of hail damage;
1. Bruises: Hail can scrape off the protective granules that coat an asphalt shingle. Once these granules are gone, the UV rays from the sun can dry out the asphalt in your shingle, and when asphalt starts to dry out, it cracks. These cracks can gradually expand until you have a leak. Thus, any shingles that are bruised are shingles that will develop leaks.
2. A Bullseye-Shaped Crack—When a large hailstone impacts your roof, it can do more than scrape off the layer of granules. A large hailstone can, in fact, rip your shingle. Look for bullseye-shaped cracks. While these cracks might not extend all the way through a shingle, they are the start of a leak and should be taken care of before the leak starts.
Repairs to Damaged Shingles
Once asphalt shingles have been damaged, there really is no way to repair them. All you can do is replace them. When your roof has suffered hail damage, the only question is how many of your shingles have been damaged. If you have sixteen damaged shingles per hundred feet, your roof is too heavily damaged to justify repairs; instead, you will need to simply replace your entire roof.
Hail damage can be a real problem. You might think that you are fine if your roof does not immediately start leaking after a hailstorm. The problem is that hail damage can take time to develop into an active leak. Catching a leak in the early stages will help to forestall water damage. In order to protect your home, you need to inspect your roof after a severe hailstorm and take whatever steps are necessary to repair your roof before problems start.
