If you're wondering how your roof tolerated another season of bad weather and storms, call a roofer to climb up on your roof and check for signs of damage. If you don't know much about roofing, you may not know what to look for yourself, and finding small areas of damage is important so they won't get bigger and start leaking.
You probably know that missing shingles or holes in the roof are bad signs, but here are four other signs of damage the roofing contractor will look for that you may not know about.
1. Lifted Shingles Where Nails Back Out
If your roof is old, the roofing nails may be worn enough that they can't hold to the deck any longer. When this happens, the nails back out and press against the shingles on top of them. This lifts the shingles slightly. This type of damage is difficult to see from the ground, but the roofer will catch these nail pops when examining your roof closely from on top of your house.
2. A Widespread Loss Of Granules
When your roof loses a lot of granules, your roof may look dark or bald. This is more than a cosmetic issue—it's a sign your roof is worn down. If granules are just lost in one area where tree branches have been scraping the shingles, the roofer might just put new shingles on or add more granules. When granules are missing all over the roof, that's a sign it's time for a roof replacement.
3. Circular Dents On The Shingles
Circular dents are a sign of hail damage. These are often hard to detect from your yard, but they're easy to see up close. The roofer has to mark and count the dents to determine if a roof replacement is needed or if just the shingles with dents need to be replaced.
Your roofing contractor can tell the difference between dents that are fairly new and dents that are old. The distinction is important since old dents are more likely to be leaking. Your insurance agent also wants to know if the dents are new or old since you only have a limited time to file a claim for hail damage repair.
4. Blisters On The Shingles
Blisters are a sign of an overheated roof. Your roof can get too hot when attic ventilation isn't sufficient. Along with blisters, your roofer may find shingles with the ends curled up. If only a few shingles have this damage, they can be replaced and the roofing contractor can improve attic ventilation so the problem doesn't happen again. If blisters and curling are all over the roof, the roofer may recommend a roof replacement.
