Metal roof restorations

A properly executed metal roof restoration includes an on-roof inspection with photos, replacement of failed or corroded screws and washers, repair of flashings and sealants at all penetrations and wall junctions, thorough roof cleaning and surface preparation, rust treatment and priming where rust is present, and application of a sealing and recoating system appropriate for the substrate and exposure level. It ends with a final quality inspection, site clean, and workmanship documentation. What it does not include is a solution for roofs with through-corrosion across multiple sheet sections or structural failure. Those roofs need re-roofing, not restoration.

Yes. Colorbond roof restoration is a significant part of our work across Brisbane and the Sunshine Coast. Colorbond steel can oxidise and fade over time, and fastener washers on exposed-fix Colorbond roofs deteriorate under Queensland UV. A restoration on a Colorbond roof in good structural condition, which includes fastener replacement, flashing and sealant repairs, thorough prep, and an appropriate recoating system, can extend the roof's serviceable life substantially.

Most residential metal roof restorations take between two and four days depending on roof size, pitch, access, the extent of repairs required before coating, and weather conditions. The repair and preparation stages take the most time on roofs with significant fastener replacement or rust treatment work. We provide a realistic timeline in the written quote before any work begins.

If the leaks are at specific identifiable failure points such as perished screw washers, failed flashing sealant, or cracked cappings, yes. A restoration that includes thorough repairs at those points before coating is applied will address the cause of the water ingress. If the leaks are widespread across the roof and the result of systemic sheet corrosion or structural failure rather than specific repair-able points, a restoration is not the right solution. That distinction is why the inspection and repair scope comes before any coating is applied.

Yes, and it is one of the most important steps. We assess fastener and washer condition across the full roof surface during inspection and replace those that are corroded, backed out, or have perished washers. On coastal Sunshine Coast properties we specify corrosion-resistant fasteners appropriate for the salt air environment. Roof screw replacement during a restoration addresses what is often the primary source of water ingress at fastener points and is a non-negotiable part of a properly executed restoration.

A restoration is for a roof that is structurally sound but showing surface-level deterioration. It involves repairs, prep, and recoating to extend the existing roof's serviceable life. A re-roof removes the old roofing system and installs a new one. Restoration costs less but is only the right option when the roof substrate can genuinely support it. When corrosion is widespread, when leaks are recurring across multiple points, or when the sheeting has deteriorated past the point where coating adds value, re-roofing delivers better long-term value. We will give you an honest comparison of both options during the inspection process.

It depends on the condition of the roof. Salt air accelerates corrosion at fasteners, lap edges, and flashing points, which means coastal roofs often have a higher proportion of fastener replacement and rust treatment in their restoration scope than equivalent inland properties. If the sheets are still structurally sound and the corrosion is at the surface rather than through the metal, a restoration with the right coastal-appropriate materials is worthwhile. If corrosion is widespread or the sheets are already compromised, re-roofing is the more cost-effective decision. The inspection tells you which situation you are in.

The key maintenance tasks after a metal roof restoration are keeping gutters and downpipes clear of debris, inspecting flashings and cappings annually for any sealant cracking or lifting, checking penetration seals around solar panel mounts and vents every few years, and on coastal properties washing the roof surface annually to remove salt deposit buildup. The restoration coating system extends the protection on the roof surface but does not eliminate the need for periodic inspection. We cover maintenance recommendations in the handover documentation at the completion of every restoration.
