How Do You Know It’s Time to Replace Your Roof? 24.

Here are some of the common ways you can know whether your roof needs to be repaired or replaced. You want to ensure your roof is in good condition in order to protect the integrity of your home and keep the rain out.Shingles Curling at the EdgesSingles that spend a lot of time in the heat can begin to curl up at the edges as they wear out. This curling can lead to problems in windy weather as the wind can catch the uplifted edges and pull them up further, allowing rain to blow under.Broken or Missing ShinglesAs shingles wear out, they become brittle and break. When you notice bare spots on your roof from shingles that have gone missing, it’s time to do something. Noticing broken pieces off your shingles may mean that just a few shingles need to be replaced, but if it is a pattern that you see repeating across the roof, it’s probably time to have a new roof installed.Missing GranulesThe granules on your shingles can be washed away over time, leaving bare spots. While this may not seem like a huge deal, it does show significant wear on your roof and may indicate the need for replacement. It can also indicate the need to repair other parts of your roof as an increased amount of water from drainage problems can cause uneven wear.Buckling ShinglesA buckle in your shingles is a lifted ridge, almost like a bubble, that usually runs vertically up the roof. Two possible causes for buckling include if your previous roof was not installed properly or if the underlayment was wet when the shingles were placed over it. That said, even a properly installed roof can begin to buckle with age. The problem with this is that the wind can easily catch those shingles and pull them off the roof, leaving bare places where water can enter your home.
