Life can be hectic enough without worrying about the roof that covers your home. However, if you've had some problems with the roof in the past, you might start to think about whether you are going to need a new roof soon. Being able to recognize signs that you need a roof can help you start saving for the expense so that it's more manageable and you can prepare to be out of the house while the work is being done. Here are three signs that could indicate you're in need of a roof replacement.
You See Damaged Shingles
A common sign that you need to pay attention to the integrity of your roof is that the individual shingles on top of it start to curl and buckle. You may also see signs of algae and mold, which can eat away at shingles and spread until they affect the integrity of the structure itself. If you see extensive damage to the shingles on your roof, it is not unreasonable to imagine that the entire roof might need replacement.
Even if the shingles don't seem damaged, there could still be a problem. You may have replaced shingles here and there over time, thinking that missing shingles are inevitable. However, it's important to note that missing shingles could themselves be a sign that the roof is aging and needs to be replaced.
Your Steps on the Roof Feel Spongy or Weak
If you ever have the opportunity to climb up on your roof to assess its condition, you're likely to take a few steps on the roof itself. If you do this and notice there are some weak spots or that your steps feel "spongy" with some give as you walk across the structure, that could indicate moisture damage of some kind. The roof surface should be hard and feel stable under your feet; if that's not the case, you might indeed need to think about replacing it.
You Aren't Sure How Old the Roof Is
It could be that your roof is simply too old and you need to consider replacing it before you experience major problems. Most asphalt shingle roofs have a life of about 20 years or so, for instance; if you've bought a house that is older than that and you have no information about work done on it, it could very well be that it has to be replaced very soon.
Once you've recognized the signs above, you'll understand that it's time to start thinking about a new roof. Contact one of the roofing contractors nearby and have them come out to inspect your roof; they can give you specialized advice that will give you a more definite idea about whether you need to replace it.
