How Do I Know When My Roof Needs to Be Replaced?
Whether your roof is new or has been around for a while, it is vital to keep it in top shape so that it can do its job. You don’t want a leak to wreak havoc on your home. When you are deciding whether you need a new roof, it is important to keep in mind the longevity of the materials and the construction of your roof.
The lifespan of a roof is largely determined by the number of layers of shingles and the ventilation provided by the roof. It also depends on the material used. For example, if you have a copper roof, it can last for up to 50 years. However, a shingle roof, on the other hand, will only last about 20 years. This may be a good reason to consider a new roof.
Another sign that you need a new roof is the appearance of moss. Moss can grow on your roof over time, especially in areas with a lot of shade. Moss can also cause a roof to appear like a fairytale cabin in the woods. However, it is not a good sign if you are not sure that it is actually a sign of damage. If you notice that your roof is covered with moss, you should get it inspected as soon as possible.
The most obvious sign that you need a new roof is if you see any shingles falling off. This will happen when the adhesive holding the bottom of the shingle separates from the course below. However, you can also have shingles fall off when a gust of wind causes them to bend in two.
Besides a lack of moss, another sign that your roof is in need of a replacement is that it is drooping or sagging. A sagging roof can lead to partial cave-ins and can also cause water damage to your home. This can cause mold and mildew to grow. Fortunately, it is not impossible to replace the shingles and make your roof look as good as new.
The first thing to check when you suspect that your roof needs a replacement is the attic. Using a flashlight, look for streaks and stains on the ceiling. These can be caused by water damage, but they can also be due to mold and mildew.
Another sign that you need a replacement is if you notice that the roof vent housing is cracked. This is because a crack in the housing allows moisture to enter the attic. In some cases, a contractor can fix a small leak, but in other cases, it may be necessary to replace the entire roof. The National Roofing Contractors Association recommends that you check the attic at sunset. You will also want to check the attic for rotting tiles or other signs of roof damage.
The best way to determine when your roof needs a replacement is to have it inspected by a professional. While this may seem like an expensive undertaking, it can save you from future expensive repairs. It’s also important to know when the last time your roof was replaced. If you live in a neighborhood where homes have been replaced regularly, it may be a good idea to check out your neighbors’ home improvement records.
