The short version
A Melbourne winter is not a cyclone season. It is weeks of damp, a few hard fronts, and roofs that never quite dry on the shady side. Clay and concrete move. Old bedding that felt solid in a heatwave shrinks and cracks. Wind from the south pushes rain up laps and under aprons that a vertical shower would have missed. The leak “starts” in July because that is when the path stays wet long enough to reach the plaster. The path was a spring conversation you did not have.
Call while it is leaking if you can do it safely from inside. An active drip is easier to match to a bay than a memory of one. Buckets are fine. Ladders in the wet are how a leak becomes an injury.
South pitches and long wet
Walk around a winter roof in Glen Iris or Preston and the south elevation is the dark one. Lichen holds moisture. Bedding stays soft. A hairline at the hip that was cosmetic in January becomes a wick. Inside, the stain prefers the corner under that pitch, often a bedroom the sun never warms. People repaint the corner in October and meet it again the next July. Paint is not the path.
Valleys on the same side collect leaf litter that winter rain turns into a dam. Water sits, finds the lap of the iron, and enters beside a tile that is individually sound. Clearing a dam is maintenance if the iron is sound. It is a replacement if winter has been sitting in rust for years. We look before we tell you to wait for a dry week and a broom.
The work is a leaking roof in Melbourne. Winter is when that page gets busy. The booking is still an inspection, not a season package. We do not sell a “winter roof” product. We find which detail the season is using.
Mortar, flashings, and wind-driven rain
Bedding mixed decades ago loses the fight with movement. You see a crack along the junction between ridge cap and tile, sometimes only on the weather face. Vertical rain misses it. A southerly does not. That is why a roof can pass a still-day look and fail on the night the front arrives. Photos taken in the calm will still show the crack if someone is on the roof. The driveway will not.
Chimney aprons and wall flashings work the same way. The upstand relies on a seal that summer heat has pulled. Wind pushes water up the apron and down the cavity or onto the top plate. The stain appears in the wall, and everyone looks at windows. Check the roof junction before you buy sealant for the architrave. The chimney flashing note is the detail version. Winter is simply when the detail gets an audience.
Metal roofs add a cold-weather trick. Condensation on the underside of a sheet, on a still morning, drips like a leak and stops when the sun hits. If the drip happens when it is not raining, say that when you book. We will look for a lap anyway. We would rather separate condensation from a winter lap leak than coat the wrong one.
What to do during a wet week
Catch the water, move the bed, and kill power to a fitting that is wet. Photograph the ceiling each morning so the growth of the mark is a record, not a mood. Note the wind direction if you know it. That note sometimes matches the elevation we find open. Do not cut the plaster out in the middle of a front unless it is collapsing. You may need a dry day and an electrician, and a hole in the ceiling in driving rain helps nobody.
Emergency covers exist for roofs that are actively flooding and cannot wait for tiles. They are a bridge. The tarp note is that bridge. A tarp through July is not a repair, and a winter of buckets is not a personality. Book the inspection for the first safe day on the roof. We can learn a lot from the roof space even when the tiles are too slick to walk. We will say what we could not see.
After it dries
The mistake is relief. September sun shrinks the path, the stain halts, and the quote feels optional beside summer plans. The path is still there. Winter found it once and will find it again, often wider. Fix the detail in the mild weeks if you did not fix it in the wet. If the whole field of ridges opened together, the winter was delivering a restore decision, not a single tile. Size the job from the other hips, not from the one stain you lived with.
A roof that only leaks in the heaviest front, at the eave, may be overflow. Gutters that cannot cope in a winter downpour imitate a roof leak with high fidelity. Look at the gutter before you restore the tile. Both can be true. Only one might be.
Through the wet months
- 1. Record the rooms, the wind, and whether water is active
- 2. Keep people off the wet roof
- 3. Inspect the path, including the south pitch and the aprons
- 4. Repair the detail, or scope the restore if the ridges have all opened
- 5. Do not retire the quote because October looks dry
