When and why Gold Coast roofs leak
Four wet months in a row
February averages 183.4 mm at the Gold Coast Seaway, with January at 136.7 mm, December at 135.4 mm and March at 134.0 mm. December and March also bring the most rainy days. A roof that stays dry all winter can start dripping in the first proper summer storm.
Downpours, not drizzle
During ex-Tropical Cyclone Alfred, the Albert River catchment behind the Gold Coast averaged about 400 mm over five days in March 2025. Rain that heavy overfills gutters and valleys, and water backs up under tiles and flashings that cope fine in ordinary showers.
Rain blown sideways
Strong winds like those in the Christmas 2023 storms drive rain under ridge caps and past flashings. If a leak only appears when the wind comes from one direction, the entry point is usually on the side of the roof facing it.
Damp air that mimics a leak
Afternoon humidity averages 70% in January and February. Condensation on the underside of a metal roof can drip like a leak, so a good roofer rules it out before pulling anything apart. Our guide to condensation or a leak explains the difference.
How a roofer tracks it down
Water usually comes through the ceiling some distance from where it gets in. It runs along battens and sarking first, so the roofer works uphill from the stain, checking tiles, ridge mortar, flashings around anything that pokes through the roof, and the valleys where two slopes meet.
Stubborn leaks may need a hose test on a dry day, with someone watching inside. Once it's found, the fix is usually a replaced tile, a resealed flashing, a cleared valley or new screws on metal. See leak detection and our national roof leak repair page.
If the ceiling is bulging
Keep everyone out of a room where the ceiling is sagging or bulging. Switch the power off at the switchboard if water is near light fittings. For storm damage emergencies, call the SES on 132 500.
If the leak is in recent work, or came with a flood
Under Queensland's Home Warranty Scheme, a defect that lets water into a home counts as structural. To keep a warranty claim open, lodge a complaint with the QBCC within 3 months of noticing a structural defect.
Storm or flood makes a difference for insurance. Moneysmart says most home policies cover storm and rainwater damage, but flood has its own definition and may be excluded. If you're near the Nerang River or the canals, read your PDS.
Questions for a Gold Coast roofer about a leak
- How will you find the entry point, and will you water-test it?
- Could this be condensation rather than a leak?
- Can you send photos of where the water gets in, before and after?
- Is this a one-off fix, or a sign the valley or flashing needs replacing?
- Will the repair hold through the February downpours, or is it temporary?
Your part, and the roofer's
You can
- Catch drips and move furniture and electronics away
- Note when it leaks: every shower, only in storms, or only in wind from one side
- Photograph the stain and write down the date it appeared
Leave to a roofer
- Tracing the leak from the roof
- Replacing tiles, flashings or screws
- Clearing valleys and box gutters
- Anything on a wet roof
Where we'd start
We'd book a roofer in September, the driest month on average, or soon after, to check valleys, flashings and ridge mortar before the summer rain. If a leak only shows up in big storms, we'd still chase it, and we'd tell the roofer which way the wind was blowing. That one detail often points straight to the cause. See the Gold Coast hub for more on local conditions.
