When water starts pouring into the attic or you find whole chunks of shingles in your yard, you obviously need a new roof. But sometimes, roofs are not quite as obvious when they tell you their days are numbered. Some roofs give off more subtle signs that the end is near.
Squirrels and Birds on the Roof
The occasional squirrel or bird on the roof is not a major reason to be concerned. But if you start seeing these animals on the roof again and again, that's not a good sign. It likely means they have built a nest up there, which likely means your roof is damaged somewhere — and they are making the damage worse. It's common for shingles to peel away at the roof's edge near the eaves, and then animals make their way in. By the time this happens, the rest of your roof is often starting to break down, too, and you'll want to have it replaced before things get any worse.
Granules in Your Gutters
Every year, you should be cleaning out your gutters. (If you have trees overhanging your roof, you should really be doing this multiple times per year.) As you do so, pay attention to the material you are pulling out. If it looks like little pebbles or chunks of asphalt, those are granules that have begun getting rinsed off the shingles. Shingles without granules do not last very long, as it's the job of the granules to keep water flowing off the roof. Granule loss is a sign you need your roof replaced soon.
Moisture in the Attic
Go into the attic, and take note of the humidity levels. If it is really humid in the attic, you might have a leak somewhere (especially if it just rained.) It's a common misconception that leaks always result in big, noticeable puddles. First, a tiny bit of water usually seeps in along the edges of a few missing or damaged shingles. This does not cause any noticeable puddles, but it can lead to a generally moist feeling in the attic. Mold growth on the rafters and insulation is also a sign of moisture that is likely due to a failing roof.
If you notice any of the signs above, contact a roofing contractor and have them come take a look. Chances are high that you need a new roof and your current roof is trying to tell you so.
