Gutters, fascia and downpipes

Gutters are sized to the roof area they drain and the rainfall they need to handle. An undersized gutter overflows in heavy rain however well it is installed, which is why gutters are usually worth replacing at the same time as the roof.

Coast and bushfire

On bushfire-prone land, gutter guard does more than keep leaves out: it reduces the build-up of dry debris that embers can ignite, so the material it is made from matters.

Near the sea, the salt that affects roof sheeting affects gutters and downpipes too. Gutters hold water and debris, so they often show corrosion before the roof does.
