GutterBrush can prevent this from happening.

Excessive amounts of water overflowing from your gutter system could cause a number of serious problems around your home, some of which could cause you hundreds if not thousands of dollars to repair. But there are just some things that no gutter protection system, even GutterBrush, can solve. One of those situations is a heavy deluge of rain that courses down a roof’s slope and into the gutter with such force that it can not be properly channeled into the gutter and out the downspout. However, leaking or overflowing gutters should never be ignored and a properly installed and clean gutter system should function to move water safely down the gutter and out the downspout in every other type of rain. If they leak or overflow during normal conditions perhaps we can help you to maximize the effectiveness of your gutters and gutter protection system during normal rainfall conditions.

First, if your house is fairly long where the gutters are continuous along the entire length and the only downspouts are on both ends this could cause some over flowing and leaking to occur. Most homeowners prefer this gutter/downspout configuration for aesthetic reasons because a downspout does not have to be installed right in the middle of the house which is usually right near the entrance to the house. However, often times only having a downspout at the end of the gutter system leads to the inability for the gutter system to handle the volume of rain that is falling. An effective solution to this problem is to have the one end raised just as high as you can so that the flow will be sufficient for the water to exit the preferred main exit end before ever running over. You can also investigate the installation of a large gutter on your home’s exterior to accommodate larger volumes of water flow.

Second, make sure your gutters are not leaking as this can lead to the misidentification of the problem you face. To quickly and effectively repair a leaky gutter, first remove debris and wash out the gutters with water. Second, apply a silicone gutter seam sealant to gutter seams, exposed nail/screw heads, and minor holes as needed. Third, you should absolutely replace any section of gutter that is pitted or rusted through. Fourth, make sure that all gutter sections are secured properly to the fascia boards and replace any rotted fascia boards as needed. Fifth, install drip flashing around all roof edges. Finally, fill the gutters with water using a garden hose to check for leaks and proper drainage. Next time it rains watch the gutters for leaks and overflows. If water still overflows the gutters, then you may need to adjust the slope towards the downspouts and or add additional downspouts as previously mentioned. In addition, you might consider installing larger downspouts that will help prevent gutter overflow but these should be coupled with the installation of downspout extensions to divert water away from the house structure in order to avoid costly water damage to your property.
