Good Repair Guide: External gutters
Product Description
Roof gutters are an important component of the building envelope, designed to control the disposal of rainwater from the roof. The most important functions of gutters are to help protect against:
- excessive or concentrated wetting of external wall surfaces
- water getting inside the building roof space or wall framing
- increased wetness of soils around the building and subsequent increased moisture loads on basement waterproofing
- undermining of areas around the building where there is controlled spillage onto the ground.
Leaking or overflowing gutters may cause problems with dampness in subfloor areas or basements or elevated moisture levels in cladding and within wall framing.
This Good Repair Guide covers the repair or replacement of fully accessible metal and plastic external gutters around the outside perimeter of the building that are fixed to a fascia board or rafter ends. It does not cover gutters that are concealed behind a proprietary metal fascia or internal or within-roof gutters.
