Gutter Maintenance

Gutter or spouting blockages can cause flooding because of the build-up of debris. Regular inscpection and maintenance must be carried out to ensure that gutters are free draining, overflow outlets can also prevent damage.

The COP does not recommend permanent gutter leaf guards. Although they do prevent large pieces of debris from obstructing the outlets, they allow finer particles to collect on the sole of the guttering. Without regular maintenance, the prolonged wetting of the interface between any debris and the metal can lead to early corrosion of the roof or gutter. The decay of organic matter such as leaves can produce organic acids, which will also accelerate corrosion.

The build-up of matter on the upper surface of the leaf guard can also form a poultice, which increases the time of wetness and acidity and can accelerate corrosion of the roof sheet ends.
