What Is Roof Restoration?
Roof restoration is the repair, deep cleaning, and recoating of an existing roof to restore performance and appearance.
Compared with a spot roof repairs job that fixes a local fault like broken tiles or a leaking roof, restoration addresses the entire roof. Compared with a full roof replacement, restoration keeps the structure and roofing materials that are still sound. If the substrate is healthy, a full roof restoration is often the most cost effective way to protect the home’s structure with minimal disruption.

What does a roof restoration involve?
Expect inspection, repairs, pressure cleaning, sealing, and painting with a flexible membrane.
- Inspection identifies roofing issues such as cracked tiles, loose ridge caps, deteriorated pointing, and blocked gutters.
- Repairs replace damaged tiles, handle metal roof repairs where corrosion appears, and fix flashings to stop water ingress.
- Roof cleaning uses pressure to remove dirt, lichen, and mould growth so coatings bond well.
- Sealing and painting apply primer plus two to three coats to form a durable finish on tiles or metal.
DIY can suit a simple spot repair, but a professional roof restoration ensures correct primers, film builds, and safety controls. For a step by step overview, read The Process.
How much does a roof restoration cost?
Most Perth homeowners pay $4,500 to $11,000, with material and condition driving the overall cost.
- Tile roof projects often include re-bedding and re-pointing.
- Metal roofs may need rust converter and isolated sheet replacement.
- Terracotta tiles can require specialist primers and careful cleaning.
If the substrate has structural damage or widespread failure, a full replacement can be the safer long-term choice, although it is a significant investment compared to restoration.
Average roof restoration costs
Indicative Perth ranges by roof area:
- 120–160 m² roof area: $4,500–$7,000
- 170–240 m²: $6,500–$9,500
- 250–320 m²+: $8,500–$11,000+
For comparison, a full roof replacement commonly starts around $18,000–$35,000+, so restoration can deliver similar waterproofing improvements at a lower final price when the base is sound.

Example: a 200 m² roof at $32 per m² totals $6,400, then add allowances for access, repairs, and materials.

Materials and prep vary by roof type:
- Concrete tiles and older tiles may be porous and need high-build primers.
- Terracotta tiles need gentle cleaning and terracotta-specific primers.
- Colorbond and other metal roofs may need rust treatment and selected replacing metal sheets.

What factors affect roof restoration costs?
Several factors shape the restoration cost and overall cost you pay.
- Roof type: tile, terracotta tiles, Colorbond, or concrete each need different prep and coatings.
- Roof size: larger roofs require more time, more materials, and bigger crews.
- Roof pitch and complexity: steeper roofs need scaffold or edge protection which increases repair costs and coating time.
- Accessibility: tight sites or multi-storey work add handling time.
- Location and local climate: coastal exposure and other factors like high UV influence prep and product choice. Regional WA may cost more than metro.

Roof pitch and complexity
Steep pitches, multiple gables, and penetrations increase time and safety needs.
Accessibility
Limited parking or difficult ladder access adds handling hours.
Location
Metro Perth is usually cheaper than remote jobs once travel is included.
What are the signs you need a roof restoration?
