You can expect your roof to last about 25 years. However, the way you maintain your roof will determine how long it lasts. There are a number of ways that you can make your roof last longer.
Clean the Gutters
You should clean your gutters in the fall and spring. Leaves and rain can clog your gutters. Your gutters will overflow once they get clogged. This can cause water to get into your roof sheathing, which can lead to rotting.
Inspect Your Roof Regularly
You may not notice if your roof has problems unless you look at it. That is why it is a good idea to inspect your roof at least once a year. Algae growth, damaged or missing shingles, sagging and wet spots on the ceiling are some of the things that you need to look out for. Call a professional as soon as possible if you notice any problems with your roof.
Get Rid Of Any Moss
Your roof will not be affected by a small amount of moss growth. However, if there is a lot of moss on your roof, then you will need to remove it. You will need to kill the moss before you try to remove it. You can use potassium salts to kill the moss. You can also use zinc strips to keep the moss from coming back.
Trim Tree Branches
The tree branches can damage your shingles. Damage is even more likely to occur on a windy day. That is why it is a good idea to trim your branches. You will need to keep the branches at least 10 feet away from the roof. Not only can branches damage your roof but they can also invite pests.
It is a good idea to hire a professional to trim the branches. You may end up doing more harm than good if you attempt to do it yourself.
Keep Your Roof Clean
The debris that builds up on your roof will eventually start to decompose. If you sweep your roof once or twice a year, then you will be able to keep the debris to a minimum. You can also use a leaf blower to get rid of the leaves. Do not use a pressure washer. You do not want the water to end up underneath the shingles. If you do not feel comfortable doing this, then you should hire a professional.
