Your roof needs to be structurally sound. It has some very important jobs to do. One job is that your roof is supposed to protect the interior of your house from the elements. Another job for your roof is to help keep your house plumb and straight. It does this by tying the walls together at the top and turning the parts from separate pieces into one connected whole. While the walls are all fastened into the floor and the foundation, unless they are tied together at the top with the beams and trusses that make up your roof, the walls will flex and move, and your house won't be stable. There are some signs that your roof needs to be repaired that you can watch for.
Doors Won't Open/Close
One sign that your roof needs to be repaired is that your doors won't easily open or close. That's because doors depend on the house being plumb and level to be able to open and close. If the walls that the doors are attached to are just a little off, then the doors will have problems, because the frame will either grab onto the door or block it from opening. The door may also swing open or closed, for the same reason. If this happens to only one door, then check the hinges on the door to make sure that they are still securely attached to the door frame, because loose hinges can also cause these problems.
Another sign that you have problems with your roof is that you start to see water stains along the walls or ceiling. Water stains can be yellowish, or they can be brownish. But, they are a sign that you have water leaking somewhere. Depending on where the water is showing up, you might also want to check to see if there are leaks in your bathroom. It's always a good idea to check out all the things it could be before you start repairing anything. One way to see if it is a leaking roof and not leaking plumbing is if there are water stains on both stories in about the same place.
If you are worried about your roof failing, then you need to call a roof repair company and have them check out your roof. If there is a problem, you want to get it repaired sooner rather than later, because the longer you wait to fix it, the more it will cost and the more damage will happen.
