Understanding 2 Major Causes of Hail Damage Across Your Roof

If you live in an area that experienced frequent hail storms, then you may be concerned about how your roof can handle the large pieces of ice. This is a real issue and you may see hail damage across your asphalt roof. There are certain types of common damage you are likely to see. Keep reading to learn about the damage that might be noted and also to learn what you should do if you see the damage.

Lost Granules

Almost every asphalt roof is covered in granules. These granules are small pieces of ceramic that are baked into the surface of each shingle. The granules protect the shingles from adverse weather conditions, wind problems, and thermal damage. While the granules are stuck to the surface of the shingles, they can be forced from them with some pressure. 

If you inspect the outside of your home after a hail storm and see granules on the ground or in your gutter, then this is a sign that the ice has forced the granules free. This is also true if you note bare patches across the shingles.

Granule loss is a sign that your shingles are starting to age. Unfortunately, if the shingles are newer, then the loss signifies premature aging. Once the granules fall away from the shingles, the felt layers are exposed. The shingles are then likely to succumb to sun damage and are likely to dry out fairly quickly. You may see some cracks forming in the shingles over time. 

Since granule loss is something that occurs naturally over time, it is not something that directly needs to be addressed. However, if you are concerned about things like thermal damage, then speak with a roofing contractor. Granules can be added to the roof with the assistance of roofing cement if you want the rocks replaced.

Blistering Shingles

If your shingles have been subjected to numerous hail storms, then you may see your roofing shingles forming pits. These pits are sometimes referred to as shingle blistering and contractors call the damage rashing as well. The pits can form in several different ways. When the hail comes into contact with the granules it forces them off the shingles. Since the granules are baked on, the top layer of the shingles can come off with the granules. 

Also, if the granules have already come off during a previous hail storm, then the hail can penetrate the top layer of the shingles. This causes divots to form in the asphalt.

The top layer of the shingles is meant to protect the felt underneath. If the felt becomes exposed, then it will absorb water, swell, and lift off the decking surface. When this happens, the shingles will need to be replaced.

Basically, if you see pitting, then you roof will need to be replaced at some point. The good news is that you do not need to invest in a replacement immediately. However, you will need to investigate and examine your roof often to look for signs of excessive wear. Curling, wavy, and cracked shingles are all signs of excessive wear. If these sorts of shingles are not replaced, then your roof will likely form a leak. 

If you experience hail in your area, then your roof has likely been put through a great deal of strain. You will likely see some common signs of damage, but certain types do not require repairs right away. If you are uncertain about whether repairs need to be made or not, then contact a local company like Alpen Roofing. They can complete an examination and let you know what needs to be done.
