Frequently asked questions
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.
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 on-site quote settles it quickly.
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.
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.
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.
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.
