Question 1

Is roof restoration cheaper than replacement?

Accepted Answer

Yes, significantly. Restoration in Adelaide typically costs $3,000 to $7,000, while a full replacement is $15,000 to $45,000+. Restoration is usually 30 to 50% of the cost of replacing, which is why it's the better choice whenever the roof is structurally sound.

Question 2

How do I know if my roof can be restored or needs replacing?

Accepted Answer

Restoration works when the roof structure is sound and the issues are surface-level: faded colour, moss, cracked pointing, a handful of broken tiles. Replacement is needed when the roof is failing structurally — sagging timbers, leaks appearing in several different spots, mortar that crumbles to the touch across the whole roof, asbestos substrate, or tiles so brittle a coating won't hold. A free inspection settles it quickly.

Question 3

How long does each option last?

Accepted Answer

A quality restoration with a Dulux Acratex membrane system adds about 15 years of life and comes with a 15-year coating warranty. A full replacement with new Colorbond or tile lasts 30 to 50+ years. If you're staying long-term and the roof is near end of life, replacement can be better value per year.

Question 4

Can I restore a Colorbond / metal roof?

Accepted Answer

Yes — metal roofs can be cleaned, treated for rust and re-coated, which is a form of restoration. But if a steel roof has rusted through in multiple places, re-sheeting (replacement) is the right call. Tile roofs are the most common restoration candidates in Adelaide.

Question 5

Will restoration hide a roof that should be replaced?

Accepted Answer

A reputable roofer won't restore a roof that needs replacing — it's a waste of your money and ours. If the structure is gone, a fresh coat just buys a year or two before the leaks return. We tell you honestly which side of the line your roof is on, even when restoration would be the easier sale.

Question 6

Which adds more value when selling?

Accepted Answer

Both help, but for different reasons. A restoration makes the home present far better for relatively little spend, ideal before listing. A full replacement removes the biggest 'unknown future cost' a buyer worries about and comes with a transferable warranty, which valuers and buyers both reward.
