Tile roof replacement on the Sunshine Coast
Tile roof replacement means stripping an existing concrete or terracotta tile roof and putting a new roof on the same frame, either new tiles or steel sheeting. Roofer Sunshine Coast arranges this work with independent local roofing contractors across the coast and hinterland. It is one of the most common jobs on brick-and-tile houses built in the 1970s, 1980s and 1990s, which make up a large share of many established suburbs here.
How tile roofs fail in this climate
Tiles themselves can last a very long time. What wears out is everything around them, and the surface of concrete tiles.
- Porous concrete tiles. Once the surface coating erodes, concrete tiles absorb water, grow lichen and become brittle. Walking on them causes cracks.
- Failed ridge bedding. Mortar under ridge and hip caps cracks with heat and movement, and storm winds then push rain under the caps.
- Perished or missing sarking. Many older roofs have no sarking, or foil that has torn. Wind-driven rain and dust then reach the ceiling.
- Rusted valley irons. Leaf litter holds water in valleys, and older valley irons rust through.
- Tired battens. Timber battens that have been wet repeatedly can rot or loosen their fixings.
Re-tile or convert to steel?
Re-tiling keeps the look of the house and the street, gives good rain-noise performance and suits roofs with enough pitch. It is heavier work and the slowest option.
Converting to steel removes a lot of weight from the frame, cuts down the number of joints and suits many owners who want a lighter, cooler-coloured roof. Battens, fixings and flashings change, and some homes may need building approval for the change of material. Our Colorbond vs tile comparison sets out the trade-offs in detail, and the Colorbond roofing page explains the steel side.
Before anyone quotes
A roofer should look at the tiles, the bedding and the roof space before recommending replacement. If the tiles are still sound, a targeted roof repair or restoration may be the better value, and you should hear that. If replacement is the right answer, the quote should list each item in the checklist below so you can compare one contractor with another.
The cost guide gives 2026 planning ranges for re-tiling and tile-to-steel conversions on the Sunshine Coast. Older tile roofs over extensions sometimes sit next to fibro or asbestos cement sheeting; if that applies, see asbestos roof replacement.
During and after the work
A re-tile or tile-to-steel conversion on a typical house runs over several working days once materials are on site. Tiles are heavy to strip and carry, so expect a large bin or truck and some noise. Each section is stripped, re-battened, sarked and covered before the end of the day, with tarps on standby in storm season. After handover, keep valleys and gutters clear of leaves, and have the ridges checked after a severe storm. A tile roof laid over good battens and sarking needs little else.
