The damage caused to your roof from hail isn't always obvious. It's possible for the damage to not be very visible immediately after the hail storm has passed through, but you'll see signs of damaged shingles over time. Knowing what you should look for could help you figure out the right time to have a roofing contractor repair the damage.
How To Tell A Roof Is Damaged
While a large piece of hail is likely to create damage due to how big it is, the size of the hail is not the only sign to watch out for. Small pieces of hail can cause a large amount of damage if there are high winds that cause the hail to impact the roofing material with a lot more force than usual.
If you have noticed that the hail was powerful enough to cause leaves on your plants to fall off, that is an indication that the roof should be inspected. If you do not notice damage to other areas of your home, like your siding, windows, and patio furniture, then it's likely that the roof is okay.
How To Find Hidden Damage
The worst type of hail damage is the kind that is hard to see. Underneath the shingles will be a mat that is attached directly to them, and it helps the roofing material shed water, which prevents leaks and makes the material waterproof. Unfortunately, the mat can become damaged due to the impact of hail.
What will happen as a result of a ruptured underlying mat beneath the shingles is that moisture can seep through the roofing material. It will eventually get to the roof deck, and then into the home. Be on the lookout for dark areas of shingles that appear discolored in comparison to the others, or shingles that have a crater in them. These shingles may need to be replaced.
How To Identify Missing Granules
The shingles themselves may seem uniform in color with no indentations, but they are missing the protective layer of granules on top of them. This can cause the roofing material to become weak, which shorten its lifespan. You may not have any immediate problems, but the shingles can fail prematurely. Look for small pieces of material that look like gravel in your gutters or at the bottom of your downspouts. If you see a lot of it, it means that your shingles lost those granules during the hail storm.
While this doesn't require immediate roof replacement, be aware that it will mean that the roof should be replaced prematurely.
