If your home has been through severe weather, you might have seen some very obvious signs of damage. And if your roof looked normal, you might have breathed a sigh of relief that you wouldn't have to call a contractor.
But after severe weather, there are a few things that you should be sure to check about your roof to make sure there isn't any hidden or hard-to-spot damage. The best inspection is one that's done from a ladder, where you can look closely at the surface of your roof. And if, for whatever reason, you can't get that close to your roof, you can always have a professional inspection done.
Dents in Asphalt Roofing
Asphalt shingles that have been clearly, visibly dented are a definite sign that you need roof repair. But not all denting is that obvious. When you can give a close inspection to your roof using a ladder, look for shingles with even small dimples. Try pressing on some of the shingles as well – if parts of them feel particularly spongy, it's likely that the shingle was internally damaged by hail or debris.
Dents in Metal Roofing
Dents in metal roofing are generally less serious. Metal roofs are impact-resistant, and minor denting is often cosmetic. However, you should still look for signs of damage to any paint or coating on the roof. If the surface appears to be chipped or has a "cracked" appearance, the coating will need to be replaced so that it can continue to protect the roof.
It's important to look at the gritty surface of asphalt shingles and make sure that it's in good condition. These granules are there to protect the shingles, so if you have missing granules, the asphalt shingle will fail faster – and it will also be less fire-resistant. Look for spots where the granules are gone, exposing the substrate (which will likely be black).
To find leaks, look for discolored spots in your ceiling or water dripping through during rainy weather. If your roof looked fine but you experience interior leaks later, you can ask your contractor what they think the cause might have been. Hail and storm damage may be covered differently by your homeowner's insurance than leaks due to regular wear and tear.
If you find signs of hidden damage like those listed above, it's important to get your roof fixed as quickly as possible. The longer you wait to call a contractor, the more damage everyday sun and rain can do to your roof and home. For more information, contact a company like Davis & Winslow Roofing.
