Re-roofing is the full replacement of a roof covering: the old tiles or sheets come off, the frame and battens are checked and fixed, and a new cover goes on with fresh flashings and capping. It suits owners across metropolitan Adelaide and the Adelaide Hills whose roofs leak in more than one spot, have porous or broken tiles throughout, or carry rusted iron that patching can no longer save. Roof Replacements Adelaide is a referral service, so the work is carried out by independent local roofing contractors, and the quote is free once someone has inspected the roof.
When a full re-roof makes more sense than repairs
Repairs are the right call for a cracked ridge or a single slipped tile. A re-roof becomes the sensible option when the faults are spread across the whole surface. Common signs include widespread rust and pinholes in steel, tiles that crumble when handled, sagging lines between rafters, daylight visible in the roof space, and stains on ceilings in several rooms. If a contractor keeps finding new problems every time they climb up, the money spent on patching may be better put towards a new cover. Our guide to signs you need a roof replacement covers this in more depth.
How the work runs on site
A typical job starts with scaffold or edge protection, then removal of the old covering in sections so the house is never left fully open. Once the frame is bare, the crew replaces damaged battens, straightens or packs out low spots, and fits sarking or an insulation blanket if it has been agreed. The new tiles or sheets go on next, followed by flashings at walls, chimneys and valleys, then gutters and downpipes if they are in the scope. A final clean removes screws, swarf and broken pieces from the gutters and yard. For a fuller walk-through, read what to expect during a roof replacement.
Things that are particular to Adelaide roofs
A lot of the city's housing was built between the 1950s and the 1980s with brick or brick veneer walls and concrete or terracotta tiles. Many of those roofs are now at the point where the tiles are tired and the pointing has failed. The reactive clay soils across much of the Adelaide Plains move with the seasons, which can twist rooflines and crack bedding over time, so frame checks matter. Older villas and bungalows often carry corrugated iron that has rusted at laps and nail holes. Post-war homes may have asbestos cement sheeting on the roof, eaves or a rear addition; SafeWork SA sets out when a licensed removalist is required, so check with them, and never cut, drill or walk on that material. In the Hills, the Planning and Design Code's bushfire hazard overlays can bring AS 3959 construction requirements, so ask the contractor how that affects material and detailing.
Choosing the new covering
The main decision is tile or steel. Steel, including Colorbond and Zincalume sheeting, is light, quick to lay and sheds winter rain cleanly. Tiles suit houses where the street look matters or where the owner simply prefers them. A switch from heavy tile to steel can take load off an older frame. If you are leaning one way, see Colorbond roofing, tile roof replacement or metal roof replacement for detail on each.
How the price is put together
Rather than a flat rate, a re-roof is priced from the roof itself: area and pitch, how many hips and valleys, access for scaffold and bins, the material chosen, the amount of batten and frame repair, extras such as sarking and new gutters, and whether solar panels or asbestos are involved. Because so much of that only shows up on inspection, comparing written quotes line by line is the fair way to judge them. The Adelaide roof replacement cost guide explains each factor without quoting figures.
Licences and insurance
We ask the contractors we work with to hold the licences and insurance the job needs. Before work starts, ask to see them, and check the building work contractor licence on the Consumer and Business Services (CBS) public register. A good contractor will not mind the question.
