Your gutters are an important part of your roofing system, and ensure that water is properly drained away from your house. A leaking set of gutters can cause water damage within your home, flooding in your basement, or even landscape erosion. There are a few different reasons why your gutters may be overflowing water: understanding what these reasons are can help you troubleshoot your gutters and get them working properly again as soon as possible.
The most common reason why your gutters may not be draining water properly from your roof is because of a build up of leaves and other organic debris, which is acting as a clog within the gutter or downspouts, causing water to overflow. This can be fixed relatively easily: all you have to do is get up on a ladder and clean them out by hand. Be sure to have someone hold onto the ladder while you do so to ensure that you won't fall. To prevent this from happening in the future, you may want to consider installing gutter screens on your gutter system. These screens allow water to pass through, but keep debris out, ensuring that you will have to clean your roof and gutters less often to prevent clogs.
Alternatively, your gutters may be leaking because they have aged or become physically damaged, compromising the structural integrity of your gutter system. If you see any signs of rust, cracks, holes, or other damage to your gutters, or if your gutters are physically pulling away from the side of your roof, you'll likely have to contact your local residential roofing services to have individual sections or the entire system replaced with a new and undamaged one. Keep in mind that sometimes damage may be hard to spot: you may want to run a garden hose into your gutters and see where leaks are occurring to pinpoint the location of damaged sections.
Finally, if you notice that your gutters are still overflowing even though they are undamaged and have no debris stuck within them, the issue may instead lie with the size of your gutters themselves. Gutters that are too small will not be able to move water at an adequate rate, causing overflow and leaks to occur. The only solution in this instance is to completely replace your gutters and downspouts with a larger set to ensure that water is draining properly.
