What Affects Roof Restoration Cost?
- Roof material: The biggest driver of roof restoration cost is the roofing material. Mid-rate pricing is $42/m² for concrete or terracotta tile restoration, $32/m² for metal / steel roof restoration, and $38/m² for Colorbond roof restoration.
- Roof condition: Condition changes the amount of prep and repair work needed before coatings can be applied. Good means a sound surface with cosmetic wear, while needs repair means broken tiles, rust patches or extra prep before coating, adding $15/m².
- Roof pitch: Pitch affects access, safety and labour time, so the calculator applies a multiplier to the surface and repair costs. Low pitch under 15° uses ×0.9, medium 15-30° uses ×1, and steep over 30° uses ×1.35.
- Optional extras: Extra roof works can materially change the final house roof restoration total. Add $2,500 for ridge capping rebed & repoint for the whole roof, $1,200 per valley for valley iron replacement, and $3,200 for new gutters around the full perimeter.
Roof Restoration Cost - Frequently Asked Questions
At the default medium pitch, a 150 m² roof restoration starts from $4,800 for metal / steel roof restoration, $5,700 for Colorbond roof restoration, and $6,300 for concrete or terracotta tile restoration before extras. If the roof needs repair rather than being in good condition, add $15/m², which adds $2,250 on a 150 m² roof. The displayed estimate range is typically shown at ±20% around the midpoint.
The base roof restoration cost per m2 is $32/m² for metal / steel, $38/m² for Colorbond, and $42/m² for concrete or terracotta tile restoration at medium pitch. If the roof is not in good condition, add $15/m². Roof pitch then adjusts the surface and repair costs using ×0.9 for low pitch, ×1 for medium, and ×1.35 for steep roofs.
Tile roof restoration cost is $42/m² for concrete or terracotta tiles at the default medium pitch. If the roof needs repair due to broken tiles or extra prep, the rate increases by $15/m² before pitch is applied to those costs. For a typical 150 m² tile roof, that means $6,300 in good condition or $8,550 before any optional extras.
Metal roof restoration is priced from $32/m² at medium pitch, covering clean, treatment of surface rust, prep and recoating for standard metal roofs. If the roof needs repair, add $15/m², and then apply the pitch multiplier to both the surface and repair costs. On a 150 m² roof, that equals $4,800 in good condition or $7,050 before extras.
Yes. Standard steel roof restoration is priced at $32/m², while colorbond roof restoration is $38/m² at medium pitch because it uses prep and recoating suited to Colorbond and similar pre-painted steel. For a 150 m² roof in good condition, that works out to $4,800 for steel and $5,700 for Colorbond before add-ons.
Optional add-ons can increase a house roof restoration quote beyond the base m² rate. Ridge capping rebed & repoint is $2,500 for the whole roof, valley iron replacement is $1,200 per valley, and new gutters are $3,200 for the full perimeter. Also note the minimum job charge is $2,500 AUD if the calculated total falls below that amount.
