Most tiled roof repairs come down to a handful of jobs: replacing cracked or broken tiles, rebedding and repointing ridge capping, replacing rusted valley iron, fixing flashings, tracing and fixing leaks, and clearing blocked gutters and valleys. A roof repair fixes a specific fault in an otherwise sound roof; when faults are everywhere, a restoration or replacement is better value.
The short answer
- Broken and cracked tiles: replaced with matched tiles
- Ridge capping: rebed and repoint when the mortar and pointing fail
- Valleys: rusted valley iron replaced
- Flashings: resealed or replaced around walls, chimneys and penetrations
- Leaks: traced to the cause, not patched at the stain
What counts as a roof repair
A repair fixes a specific fault so the roof keeps water out: a cracked tile, a section of loose capping, a rusted valley. It is different from a restoration, which renews the wearing parts of the whole roof, and a replacement, which strips and re-roofs it. Small faults left alone become big ones: water that gets past one tile wets the sarking, battens, insulation and ceiling below.
The most common tiled roof repairs
| Repair | Usual cause | What is involved |
|---|---|---|
| Broken or cracked tiles | Storms, hail, branches, foot traffic, age | Lift the tiles above, replace with a matched tile, check the sarking |
| Rebed and repoint | Mortar bedding and pointing breaking down under ridge and hip caps | Lift caps, rebed on fresh mortar, finish with flexible pointing |
| Valley replacement | Galvanised valley iron rusting, leaves sitting in the valley | Lift tiles, replace the valley iron, relay and seal |
| Flashings | Movement, corrosion, damage by other trades | Reseal, refix or replace flashing at walls, chimneys, skylights and vents |
| Leak repairs | Any of the above | Trace water in the roof space and on the roof, then fix the cause |
| Gutters and downpipes | Blockages, rust, sagging brackets | Clear, refix or replace |
Each repair in more detail
Broken tiles
Our yards hold over 200 tile types, so we can usually match yours from stock. See replacing a broken tile.
Ridge capping
Cracked pointing and mortar in the gutters are the signs. See roof repointing.
Valleys
Rusted valleys leak straight into the roof space. See valley repairs.
Leaks
The stain is rarely under the fault. See what to do when your roof leaks.

Materials used in roof repairs
- Matched roof tiles, new or second-hand, plus ridge, hip and barge capping
- Sand and cement for ridge and hip bedding
- Flexible pointing to seal ridge and hip capping
- Valley iron, ideally Zincalume or Colorbond rather than galvanised
- Flashing materials and storm seal for walls, chimneys and penetrations
- Sealant for small, targeted sealing around penetrations and flashing edges
All of these are stocked at our Mulgrave and Doveton yards. See roof tiles and supplies and our guide to roof sealants.
Why repairs should not wait
A cracked tile or a section of failed pointing costs little to fix. The same fault left for a few winters can mean wet insulation, stained ceilings, rotting battens and mould. There is an insurance angle too: Financial Counselling Australia has found that many refused home insurance claims rely on wear-and-tear or maintenance exclusions, so damage from a fault that was left can be harder to claim.

WorkSafe Victoria’s compliance code for housing construction puts edge protection such as guard railing ahead of harnesses and ladders when controlling the risk of falls from a roof. Our crews set up our own temporary safety rail, ladder guards and, where there are old skylights, safety nets before anyone works on the roof. Every crew member holds a working at heights qualification.
Common questions
What are the most common roof repairs?
Replacing broken tiles, rebedding and repointing ridge capping, replacing rusted valleys, fixing flashings, tracing leaks and clearing or replacing gutters.
What does roof repair mean?
Fixing a specific fault in an otherwise sound roof, such as a cracked tile or a rusted valley, as opposed to restoring or replacing the whole roof.
Why are roof repairs important?
Small faults let water reach the sarking, battens, insulation and ceiling. Fixing them early is cheaper and avoids insurance problems with wear-and-tear exclusions.
What materials are used to repair a tiled roof?
Matched tiles and capping, sand and cement bedding, flexible pointing, valley iron, flashing materials and, for small jobs, sealant.
When is a restoration better than repairs?
When faults are spread across the roof. A restoration renews the cleaning, capping, valleys and coating in one job, with a warranty.
How much do roof repairs cost?
Published figures put a tile replacement repair in Melbourne at about $315 to $1,050 a job, and a minor leak repair at about $250 to $800.
