You need a new roof in Melbourne when more than about 20 percent of tiles are crumbling, sarking is wet across large areas, a restore has already failed twice, an engineer or insurer has written replace, or iron is rusted through. Moss, powder pointing and a tired face are restore signs — book a restore, not a re-roof.
You need a new roof in Melbourne when more than about 20 percent of tiles are crumbling, sarking is wet across large areas, a restore has already failed twice, an engineer or insurer has written replace, or iron is rusted through. Moss, powder pointing and a tired face are restore signs. Roof Revival Melbourne picks a side after an on-roof inspect — we will not coat a write-off, and we will not sell a re-roof because a ridge looks dusty from the street.
This article supports the Roof Replacement Melbourne service and the roof replacement cost guide. If your list is moss, a handful of cracked tiles and powder mortar, stop here and open signs you need roof restoration instead.
Melbourne owners mix these two lists because both look like “the roof is tired”. They are not the same spend. A restore is re-bed, repoint, swap a handful of units, prep and coat when the tile body and timber are still sound. A replace is a new system — strip, battens if needed, sarking, new tile or Colorbond, flashings, valleys, disposal. Restore planning bands sit in the mid thousands to the low teens. A Melbourne re-roof commonly starts around $20,000. Painting a finished roof does not close that gap; it hides it for a season.
Restore signs we write down every week: moss and lichen on the south pitch, powder pointing on 1980s concrete, three to a dozen cracked tiles after a trade has walked the roof, a slipped ridge cap, a local valley leak, chalked coating that still has a hard tile underneath. Those jobs belong on the restoration page. They are also the jobs people try to turn into a cheap wash. A wash is prep inside a restore. It is not a new roof and it is not this article’s H1.
Replace signs are structural or systemic. The field is finished. The underlay is finished. The metal has holes. Someone with a stamp has already said the system is done. We still walk the roof. We do not argue with wet battens or tiles that snap when you lift them.
A broken tile is a repair. A field that is crumbling is a replacement. The line we use on Melbourne concrete and tired terracotta is about 20 percent of the visible field — pitted through, snapping in the hand, already patched with mismatched units, or so powdery that a new coat would sit on dust. That is not a ridge job. That is the lid finishing its life.
Eastern 1970s–80s concrete is the usual place we hit this number: Glen Waverley, Box Hill, Doncaster two-storeys that have already had one cheap spray. Coastal terracotta can look sound from the footpath and still be rotten underneath. We lift units. Under 20 percent, with dry timber, we restore. Over that band, another restore is a delay you pay for twice. Read is roof restoration worth it if you are still hoping the tiles have a decade left.
Sarking is the underlay under tiles or metal. It is the second line when water gets past a cracked unit or a failed valley. Dry, intact sarking can sit through a restore. Wet, torn, or moulded sarking across large bays means water has been in the roof space for a long time. Insulation is heavy. Battens stain. On a bad week the ceiling lining tells you before we do.
A local wet patch under one chimney or valley can be cut out after the leak is stopped. That is a repair. Wet sarking across two or three bays, or daylight through the underlay, is a system failure. Coating the tiles will not dry the roof space. Replacement puts new sarking in while the roof is open — cheaper than opening it twice. Brown stains on the foil and damp insulation after rain are the homeowner version of this sign. We confirm it on the roof, not from a hallway photo alone.
One proper restore on a sound roof is a decade-plus conversation. Two failed restores on the same lid is how people waste money. We see it after a cheap spray that never reset the bed, after a “paint only” job sold as restoration, and after a second coat on tiles that were already pitted. The brochure warranty meant nothing because the substrate was already finished.
If you have already paid for a restore and the ridges have opened again within a few years, or water is still in the same ceiling corner, do not buy a third coat. Ask for an inspect that is allowed to recommend replace. Roof Revival Melbourne will pick a side. Compare restore and replace on the same inspection — not last year’s restore invoice against a Facebook replace number. The cost guide is a planning band. Your quote follows squares, access, disposal and whether the frame is dry.
This is the cleanest replace sign we get, and we still inspect. A building inspector’s pre-sale report, an engineer’s letter after movement, or an insurer’s write-off after hail or storm can all say “replace”. Sometimes they are right. Sometimes they have seen a stain and used the strongest verb in the template. We read the report on the roof, not in the kitchen.
If the report is right, we scope a re-roof — tile or Colorbond, sarking, flashings, gutters if they belong in the same scaffold week. If the roof is still sound we say so in writing. We will not restore a write-off to win a cheaper job, and we will not replace a roof that only needs pointing so an auction looks tidy. Hail write-offs are replace; a handful of bruised units on a sound field can still be a restore-plus-claim conversation. We do not invent damage, and we do not hide it.
Older corrugated iron and tired sheet on inner-west and Peninsula stock fail by rust, not by mortar. Surface rust on a screw line or a valley can be treated. Holes, rusted-through pans, and iron that flexes underfoot are a replace. Paint over holes is a hold until the next storm, not a new roof.
Footscray, Yarraville and older Werribee South outbuildings show this every month. So do rear additions that were never detailed into the main tile roof. If the main roof is sound tile and the iron lean-to is finished, we can replace the lean-to and restore the tile — two scopes, one visit. If the iron is the house, plan a metal re-roof, not a 1980s tile restore package.
Colorbond that is chalked but sound is not rusted iron. Chalking is a face. Holes are a system. We will not sell a full replace because a dark roof looks dusty from the street in Point Cook. We will sell a replace when the sheet is done.
This is not a wash tutorial. If the roof is sound and only dirty, say so on the form. Prep wash sits inside a restore. We will not title a gutter-flush as a new roof. This is also not a default upsell. Plenty of Melbourne roofs should be restored. The worth-it article and the restoration signs guide exist so you can see the other list in full.
A sagging ridge line can be failed bedding. A sagging roof plane can be tired battens or framing. The first is often a restore. The second needs timber looked at before anyone orders tile. We do not guess that from the letterbox.
Industry figures for Melbourne re-roofs often land around the mid-to-high teens and up. Roof Revival Melbourne asks you to plan from about $20,000 for a straightforward job. Heritage slate and complex Kew roofs are more. Point Cook Colorbond changeovers are a different, usually simpler, spec. We quote squares, access and disposal — including asbestos process if the build is old enough to need it. VBA and warranty insurance apply above legal thresholds. We flag them instead of whispering.
You can usually stay in the house. The messy week is still a messy week. Solar has to be sequenced. Gutters are a priced line, not an assumed extra. The service page for roof replacement in Melbourne is the money page this article supports.
