Roof Replacement Cost Cairns 2026 — Complete Guide to Cairns Roof Replacement Prices, Cyclone Zone and Tropical Roofing Specifications

Roof Replacement Cost in Cairns 2026

Cairns roof replacement costs in 2026 are significantly higher than most Australian cities, driven by cyclone zone C specifications, a premium Far North Queensland labour market, and the need for materials rated to withstand the region's tropical humidity, cyclonic wind speeds, and wet season rainfall intensity. This guide covers roof replacement prices across Cairns and Far North Queensland in 2026.

Cairns Roof Replacement Cost by Material

• Colorbond steel roofing (cyclone-rated): $78-$118 per square metre supplied and installed
• Concrete roof tiles (cyclone-rated): $72-$108 per square metre supplied and installed

Average Total Cairns Roof Replacement Costs

• Small home (80-120m2 roof): $10,500-$19,000 Colorbond cyclone-rated
• Medium home (150-200m2 roof): $16,500-$29,000 Colorbond cyclone-rated
• Large home (250m2+ roof): $25,000-$42,000+ Colorbond cyclone-rated

Cyclone Zone C Roofing Requirements in Cairns

• Cairns is in Wind Region C under AS 4055; all roof replacement must use cyclone-rated screw fixings (not clout nails), continuous sarking, and batten spacings to manufacturer's cyclone wind rating; Queensland Building and Construction Commission (QBCC) licensed contractors must carry out all Cairns roof replacement work
• Coastal Cairns suburbs and beachside Northern Beaches areas (Palm Cove, Trinity Beach, Clifton Beach, Yorkeys Knob) within 1km of the Coral Sea require Colorbond ULTRA marine-grade steel to resist saltwater corrosion combined with cyclone zone fastening

Tropical Humidity and Roofing in Cairns

• Cairns' annual humidity (averaging 75%+) accelerates corrosion in non-marine-grade fixings and compromises standard sarking over time; specify stainless steel or hot-dipped galvanised fixings throughout for any Cairns roof replacement; IP-rated roof penetration seals are also important in Cairns' high-rainfall wet season environment
