No roof lasts forever. At some point, it'll be time to call a residential roofing company in Houston, TX. Knowing when it's a good time and when it's past due can make a big difference for your home.
One of the easiest ways to remember when you're going to need a new roof is to make note of the anniversary. Obviously, there's no need to recall the exact day, but the year is important. Has it been 10 years or 20 years since your roof was last replaced? Most asphalt shingle roofs will be good for 20-30 years. If has only been 10 years, you don't need to worry about it for a while, provided that it still appears to be in good condition. If it has already been 20 years, you'll need to have your roof replaced in the next 5-10 years.
Curling can happen in a couple different ways. Cupping is what happens when the edges of the shingles curl upwards. Crawling is what it's called when the shingles bulge in the center and the outer edges curl downwards. Either way, it indicates weathering and could be a warning sign of leaks. Depending on the severity, you may need a new roof within the year or within the next 5 years.
The great thing about individual shingles is that they can be replaced. The bad news is that the new shingles won't match the old ones. From a purely functional perspective, you can replace missing shingles for several years. They can be replaced until your roof has reached its expiration date and you need an entirely new roof anyway. However, most homeowners will opt for a new roof before then. Eventually, replacing shingles will make your roof look mismatched.
Much like missing shingles, cracked shingles can be replaced. When it comes to cracks, it's usually the result of wind damage. A telltale sign is that the cracked shingles tend to appear in clumps. You should be able to have those shingles replaced and be fine. But that's not the case if the cracking looks random and covers most of the roof. In that instance, you'll likely need a new roof within the next 3-5 years.
Moss or algae may look bad, but it's not a reason to panic. The issue is primarily a cosmetic one. Most newer shingles are algae-resistant, so it's not likely to be a problem with newer roofs. You can use a bleach wash to kill the algae or moss, but you shouldn't pressure wash it away. Pressure washing will remove the granules on your shingles and render them far less useful. Zinc strips can be installed, and they'll eventually eliminate the problem. When you do have to replace shingles or install a new roof, be certain that you choose algae-resistant shingles.
A sagging roof is a sign of much more than just a problem with your shingles. Sagging roofs usually indicate structural issues. Without an inspection it's impossible to know from the sagging itself, but the most common causes are either the decking in your attic or supports in the foundation. You need to remedy a sagging roof as quickly as possible. The problem will only get worse and costlier if left untreated. Call in an expert as soon as you can.
