Internal gutters – blockages at outlets or overflows

If an internal gutter servicing a metal roof or tile roof overflows, the only place for the water to go is into the building below. This can cause inconvenience and damage and potentially expensive repairs. Deal with blockages without delay.

Causes

Leaves or debris, balls, plastic bags

Listed under: Roof, gutters

Cause

Leaves or debris, balls, plastic bags

Repair

  • clear debris out of the gutter and/or overflow (aim to do this every three months)

  • trim back branches that overhang the roof until they are well clear

  • install dome-type leaf guards to keep out debris, and snow guards in areas with snowfall

  • if current downpipes and/or spreaders discharge directly into the gutter, investigate whether they can be redirected to another gutter

  • if the problem continues, investigate whether it is possible to provide an overflow outlet below the top of the gutter in an obvious location to give early warning of a blockages, or (even better) an additional outlet

  • check the gutter annually for any damage or deterioration to the lining and outlet
