For homeowners in Orleans roofing is an essential yet often overlooked feature of their house. Nobody wants the expense of replacing the roof on their home, but it’s important to know when you may have to do that. Most asphalt shingle roofs will last up to 30 years; if yours is older than that, it may be time for a replacement. There are obvious visible signs that it may be time to replace or repair your roof too, such as missing, cracked or curling shingles, or a leaking roof. Missing shingles can be replaced of course, although if you’re doing that frequently, a whole new roof may be called for. If your roof is at least 15 years old and you notice granules in your gutter, that may indicate a deteriorating roof. And a sagging roof is never a good sign; often that indicates a structural problem.
