When it comes to roof replacement, the decision entirely depends on your situation, budget, and the current age of your roof. It is likely time for a roof replacement when you start to notice other problems. If your energy bill suddenly gets higher, or you experience a concerning amount of roof leaking, then it's likely time for a whole roof replacement. It may be hard to tell how much damage those things have done, but both can cause wood rot or holes to appear in your roof. Either way, a roof replacement will increase the value of your home and provide extra protection from the elements. Plus, you'll have a more aesthetically pleasing home to live in, without the fear of your roof suddenly failing.
