Everything's fine all summer — then the first proper Cape cold front rolls in, and suddenly there's a brown ring spreading across the ceiling. It's the most common call we get this time of year. The good news: most winter leaks come from a handful of predictable places, and caught early they're a straightforward fix.
Why roofs leak in winter
It's simple, really: winter is when the Winelands gets its rain and wind. All through the dry summer, a small gap or a bit of perished waterproofing sits there doing no harm. Then the wind-driven winter rain arrives and pushes water sideways and uphill into places a gentle shower never reaches. Nothing new broke — the weather just found what was already there.
Where the water actually gets in
People assume a leak means a hole in the middle of the roof. Usually it's the joins and edges:
- Flashing — the metal seals where the roof meets a wall, chimney or parapet. The single most common leak point.
- Valleys — where two roof slopes meet and funnel a lot of water. If the seal or sheet is worn, it gets in here.
- Ridges & hips — the capping along the top and edges can crack or lift.
- Slipped or cracked tiles — one loose tile in the wrong spot is all it takes.
- Blocked gutters — leaves and dirt dam up the water, which then backs up under the tiles instead of draining away.
- Perished waterproofing — on flat roofs, balconies and parapets, old membrane simply gives out.
- Ageing thatch — older thatch thins and rots, and once it leaks it rarely stops (often the point people decide to convert to tile or slate).
How to tell you've actually got a leak
Watch for yellow or brown stains on the ceiling or walls, a persistent damp, musty smell, paint or plaster bubbling, and of course an actual drip in heavy rain. A patch of black mould in a ceiling corner is another tell — where there's mould, there's moisture getting in.
Tip: the wet mark on your ceiling is often not directly under the leak. Water runs along timber and tracks sideways before it drips, which is exactly why finding the true source takes a trained eye.
What to do the moment you spot one
- Contain it. Bucket under the drip, move furniture and anything that can be water-damaged.
- Relieve a bulging ceiling. If water is pooling above the ceiling board, pierce a small hole to let it drain into a bucket — a waterlogged ceiling can come down.
- Don't climb up in the wet. Get it looked at properly before the next front comes through.
A small leak is cheap to fix. The same leak ignored for a season rots roof timber, ruins ceilings and insulation, and turns into damp — a much bigger bill.
Should you patch it yourself?
Honestly — we'd rather you didn't get up on a wet roof. It's dangerous, and because leaks travel, a DIY patch over the stain usually misses the real source and just moves the problem along. Far better to have someone find where the water is genuinely getting in and seal it properly the first time.
How to stop it happening next winter
Two things save most people a lot of grief:
- Clear your gutters before the rains — blocked gutters cause a surprising number of leaks.
- Get a pre-winter roof check — flashing, valleys, ridges and loose tiles inspected and sealed while it's still dry. A short inspection now is a fraction of the cost of a water-damaged ceiling later.
