Why Do My Gutters Overflow in Heavy Rain?

Clogged Gutters

Gutter Before Gutter Guard Installation

Leaves, animal materials, dirt, debris, flowers and twigs from nearby trees cause blocked drains or overflowing waters. When clogs appear in gutters or downspouts, water is not diverted to the proper channels and instead pours out the side of the gutter. Clogs can also occur in winter, especially in alpine areas where ice dams form. Heavy rainfall or snow will cause the gutters to clog and overflow.

Box Gutters

Box gutters are popular in modern house design but also effective in subtropic locations because they can handle heavy rain. The problem with these gutters is that downspouts are susceptible to clogging. If clogged, the gutter will pool with rainwater more quickly in heavy rain. Only specific gutter protection systems that use commercial-grade mesh will suit box gutters and the heaviest rainfall. Commercial-grade mesh is stronger and spans across the box gutters without sagging. Mesh that sags will cause blockages and perpetuate water pooling and overflow.

Gutter Detachment

Heavy rainfall damages gutters, which may loosen after the rain. Gutter detachment may occur if the gutter is incorrectly fixed or secured to the roof. In these cases, you may notice leakage from the start. However, gutter detachment may also occur due to damage, water pooling or bad weather. Water cannot be diverted and channelled correctly in these cases, and overflow is likely. A quality gutter protection system can strengthen a gutter system in areas that experience bad weather.

Ember guards

Ember guards work to prevent burning embers from entering the gutter system and igniting roofs and homes. Ember guards require a hole size of 2mm or less. However, the heaviest rainfall causes the water to sheet over the gutter guards. This is a problem for homes in BAL-rated areas that also will experience heavy rainfall. A quality ember guard with a water trough design and directional holes, such as Tuffmesh Emberguard and Guttermesh Emberguard, will prevent water sheeting and overflow in heavy rains and provide bushfire protection
