The short version
A tile roof replacement cost is the cost of taking one roof off and building another that still sheds water the way a tiled Melbourne house expects. The tiles are the visible part. Under them sit battens, sarking, valleys and a bedding and pointing system that has to be new if the old one has failed. Disposal of the old field is heavy, messy and billable. Leave any of those lines off and the cheap quote is a different product.
The service page is tile roof replacement in Melbourne. Broader re-roof bands sit in the roof replacement cost guide. Use about $20,000 as the common starting point for a straightforward replacement, then expect concrete and especially terracotta to move with area, access and matching. If the existing tiles and timber are still sound, a restore on a standard home is planned around $4,000–$12,000. That is not a small replacement. It is a different job. We do not price a suburb. We price this roof.
Terracotta and concrete are not the same spend
Concrete tile is the everyday replacement on a lot of post-war and late-century Melbourne houses. The units are heavy, the labour is real, and the quote still has to include sarking, battens, valleys and a proper ridge. It is often the practical choice when the profile can be matched or when the owner wants to stay with tile and the street is not asking for a heritage profile. It is not a budget metal job with a different label.
Terracotta usually costs more because the material, the match and the handling do. Older glazed and unglazed profiles are not a single product you grab off a shelf in any colour. A streetscape that still reads as terracotta wants units that belong there, and hunting a profile takes time before anyone beds a ridge. The tiles are brittle compared with a casual carry. Breakage, cutting and the slower set all sit in the labour. If the overlay or the look of the street requires terracotta, a concrete quote is not a clever substitute. It is a different roof, and it can be the wrong roof.
Weight matters to the frame conversation. A new tile roof is not a light lid. If we are replacing tile with tile, the structure has already been carrying that kind of load, but rotten battens and tired fixings still have to be faced when the field comes off. If someone has suggested tile where the frame was built for sheet, that is an engineering conversation before it is a tile order. Roof Revival Melbourne will not sprinkle a new field over timber we have not looked at.
Disposal is a line, not a favour
Old tiles do not vanish. A full strip is a large volume of heavy waste. Tip fees, the skip, and the labour to get the material off the roof are part of replacement. A quote that says the owner will deal with the tiles has deleted a major cost. We write disposal into the scope. If an old cement sheet is hiding under the tiles, that changes who is allowed to handle the strip. Suspicion of asbestos is a stop. We inspect and refer licensed removal. We do not invent a casual dump fee for material that needs a licensed path. The quote should also say the house is not left open to weather mid-strip.
Battens and sarking decide whether the new tiles last
Battens are the timber the tiles hang on. If they are rotten, undersized, or fixed in a way that will not hold a new field, new tiles on old battens are a short roof. Many cheap replacement numbers assume the timber is perfect because nobody has lifted a tile yet. We allow for what we can see, and we say what happens if the strip shows more. A provisional approach is honest. A silent assumption is how the price jumps on day two, or how the new roof fails on the old wood.
Sarking is the underlay that backs up the tiles. Tiles shed most of the water. They are not a sealed membrane, and Melbourne wind will drive rain uphill. A named sarking, lapped and detailed into the valleys and the eaves, is part of a modern tile replacement. “Existing sarking if it looks okay” is a gamble you only understand after the first storm. If the old underlay is perished, torn, or missing in bays, it is replaced in this scope. Insulation can be discussed while the roof is open. We name that choice. We do not slide it in after you have signed a tile-only number.
Valleys, flashings and the ridge system belong in the same sentence. New tiles with reused rusted valley trays leak at the tray. New tiles with powder pointing copied from the failed roof leak at the ridge. Bedding and pointing are part of the new roof, not a restore add-on you can skip because the tiles are new. Gutters are either in the price or they are a clear option. They are not “everyone knows that’s included.”
The lines that separate two tile quotes
Compare these before you compare totals. A lower number that drops two rows is not a discount on the same roof.
| Line | Concrete tile job | Terracotta job |
| Tile supply | A current profile you can still buy | Match, lead time, and breakage in the labour |
| Disposal | Heavy strip, skip and tip fees written in | Same duty, often slower handling |
| Battens | New where the timber will not carry the field | New where the timber will not carry the field |
| Sarking | Product named, not “if we feel like it” | Product named, detailed into valleys |
| Ridges and valleys | New bedding, pointing and trays | New bedding, pointing and trays, plus the match at hips |
| Access | Height and site written in | Height, site, and slower carrying |
| Overlay or streetscape | Confirm tile is what the street allows | Often the reason terracotta was chosen |
The replacement cost guide is where those finished-job bands are set out for planning. This article is the reason the tile version of that spend is lumpy: the heavy waste, the timber, and the underlay are the job, and terracotta matching adds another layer when the house needs it.
What pushes a tile replacement above the starting band
Area, hips and valleys move the price. Two storeys add time at every lift. A steep pitch slows bedding and makes edge protection non-negotiable. Solar has to be planned, or the bays under the panels are not part of the new roof. Penetrations and a box gutter add flashing labour that a per-tile rumour never includes. Two houses in the same street can still need different tile roofs. Roof Revival Melbourne writes that difference down. We do not average it into a postcode.
When you should not buy a new tile roof yet
If the tile body is still hard, the sarking is dry and the leaks are at ridges, valleys and broken units, replacement is often the expensive way to buy a restore. A standard restore is planned around $4,000–$12,000 because it keeps the field and rebuilds the waterproofing details. Replacement commonly starts from about $20,000 because it throws the field away and starts again. Paint does not replace battens or sarking. We will say which job you have. If the field is crumbling past a sensible repair allowance, we will say replace, and whether that replace should stay in tile.
Typical inspect-to-scope process
- 1. Inspect the field, the roof space and the access
- 2. Decide concrete, terracotta, or a restore if the lid has life
- 3. Scope disposal, battens, sarking, valleys and ridges
- 4. Quote the replacement against that list
- 5. Strip, install and point to the written scope
