Roof — Guttering in Humpty Doo

Gutter replacement costs $40–$80 per linear metre installed, including materials. A standard house with 40m of guttering costs $1,600–$3,200. Downpipes cost $300–$600 each to replace. Quad and fascia gutter profiles are the most common and cost-effective options in Australia.

Gutters should be cleaned at least twice a year — once in autumn (after leaves fall) and once in spring (clearing spring pollen and debris). Properties near large gum or deciduous trees may need quarterly cleaning. Blocked gutters cause roof damage, water ingress, and can be a bushfire risk in ember-prone areas.

Gutter guards significantly reduce cleaning frequency and prevent blockages. Mesh gutter guards cost $15–$35/m installed. They're particularly worthwhile for properties near trees or in bushfire-prone areas (ember protection). No gutter guard is completely maintenance-free — an annual inspection is still recommended.

Signs include visible rust, holes, or cracks; gutters pulling away from the fascia; persistent leaking at joins; visible sagging when viewed from ground level; and water overflowing during moderate rainfall. Gutters typically last 15–25 years for Colorbond and 10–15 years for painted galvanised steel.

Colorbond steel guttering is the gold standard in Australia — powder-coated, rust-resistant, and available in 22 colours to match roofing. It lasts 25–30+ years with minimal maintenance. It costs 20–30% more than standard galvanised steel but the longevity and appearance justify the premium for most homeowners.
