Roofing Glenfield

For 1970s concrete tile roofs in Glenfield (now 45–55 years old), the repair-vs-replace decision depends on the scale of failure. If fewer than 10% of tiles are cracked and the ridge mortar is the main issue, targeted repair and re-pointing may add 8–10 years of serviceable life at lower cost. If more than 20% of tiles are cracked, slipped, or delaminating, if the valley iron is also corroded, or if the sarking underlay has failed, full replacement with long-run Colorsteel is significantly more cost-effective over a 10-year horizon. OneRoofing provides a written comparison of both options, including projected repair costs over 5 and 10 years versus replacement cost and expected new roof lifespan, so you can make a fully informed decision.

For Glenfield's 1960s–80s suburban homes, the most popular replacement choice is 0.55mm Colorsteel Enamel PVDF in a trimdek (secret-fix) or Custom Orb corrugated profile. The trimdek hidden-fix system has no exposed fasteners, eliminating the main fastener corrosion entry point. The Custom Orb profile suits pre-war and character homes. Both carry a 40-year BlueScope material warranty. For Glenfield homeowners who prefer a tile aesthetic without the weight, maintenance, and structural load of concrete tiles, Decra or Gerard stone-coated metal tiles (steel substrate with stone-chip coating, 30-year warranty) are an excellent premium alternative. OneRoofing carries samples of all profiles for your free consultation.

Yes. Ridge and hip capping re-bedding and re-pointing is available as a standalone service in Glenfield for concrete tile roofs where the main tiles are structurally sound but the original cement mortar bedding has deteriorated. The process involves removing all existing cappings, grinding off old mortar, re-bedding with fresh cement, resetting cappings, and applying flexible polymer pointing compound. This is a cost-effective intervention that typically costs $900–$2,200 for a standard Glenfield home and should be done every 20–25 years as part of a proactive maintenance programme.

A standard Glenfield suburban home roof replacement (130–200 m²) takes 2–3 working days from strip to completion for long-run steel, or 3–4 days for stone-coated metal tiles. We never leave the structure exposed to rain overnight: temporary Sisalation underlay is tacked over any stripped sections at the end of each day. Scaffolding is erected on day one before any stripping begins. We provide a written project schedule in your quote so you know exactly what to expect each day.
