How to Quote a Roof Restoration in Australia

Step-by-step guide to quoting roof restorations. Covers tile and Colorbond roofs with cleaning, repairs, repointing, sealing, and painting costs.

What a Roof Restoration Quote Should Include

A complete roof restoration quote covers: high-pressure cleaning, broken tile replacement, ridge cap repointing with flexible compound, valley and flashing repairs, sealer/primer coat, two coats of roof membrane paint, gutter clean-out, and safety equipment (harnesses, edge protection, or scaffold). Always specify the paint brand, colour, and warranty.

Roof Restoration Costs in 2026

Standard single-storey tile roof restoration: $3,500–$7,000. Double-storey: $5,500–$12,000. Colorbond re-coating: $3,000–$6,000 for single-storey. Costs depend on roof area, condition, access, and the number of repairs needed. Ridge cap repointing alone costs $40–$70/linear metre. Broken tile replacement: $20–$40 per tile.

Inspecting Before Quoting

Always inspect the roof before quoting. Check: number of broken or cracked tiles, ridge cap condition (cracked pointing), valley irons (rusted or worn), flashing condition, gutter and fascia state, and overall roof surface condition. Take photos during inspection and note the specific repairs needed. This prevents surprises and builds client trust.

Safety and Access Costs

Roof work requires fall protection under WHS regulations. Include the cost of: safety harness systems, edge protection or scaffold for steep or high roofs, and access equipment. For single-storey homes, a harness system is usually sufficient ($200–$400 per job). Double-storey or steep roofs may require scaffold at $1,500–$5,000.

Roof Restoration Quoting Mistakes

1. Not inspecting the roof in person. 2. Underestimating repair quantities. 3. Forgetting safety equipment costs. 4. Not accounting for double-storey access complexity. 5. Quoting cheap paint that won't last — use quality roof membrane for a warranty-backed result.
