Roofing help in TownsvilleAlthea wrote the rules. Your roof still has to keep them.

Townsville builds roofs for cyclones because of what Althea did in 1971, when the worst damage was to roofs that were poorly fixed or not fixed at all. Most roof work here comes down to keeping sheets, screws, battens and tie-downs sound, and keeping wet-season rain out. We pass jobs to licence-checked local roofers where we have them, and we'll tell you straight away if we don't.

What's different about roofs in Townsville

Althea is why the rules exist

Cyclone Althea crossed near Rollingstone, about 50 km north of the city, on Christmas Eve 1971, with gusts of 196 km/h recorded at the airport. Council later counted about 200 houses levelled and up to 4,000 damaged. Engineers found roofs took the most widespread damage, and Queensland brought in its first statewide cyclone building rules in 1975. Townsville was the first place to adopt them.

What a Townsville house is designed for

The Queensland Reconstruction Authority (QRA) puts coastal areas north of Bundaberg, Townsville included, in Wind Region C. Homes there are designed for gusts of 250 km/h, which the Bureau calls mid-Category 4. Each house then gets a rating from C1 to C4 depending on exposure, and the QRA's rule of thumb is simple: the better the view, the higher the rating.

Yasi felt smaller than the headlines

The media called it Category 5, but the QRA says Townsville homes felt only Category 1 or 2 winds in Yasi. Roofs still came off and went down streets. The QRA's lesson is that damage at winds well below a home's design speed points to a weakness, and it should be fixed during the repair, not patched over.

Older homes, weaker fixings

Homes built after the mid-1980s should have been designed for the wind at their site. Homes built before 1985 usually take more damage. Cyclone Testing Station investigations found a common fault in older houses: sheets screwed properly to battens, but battens poorly fixed to trusses, so the wind lifted the lot.

A wet season that swings wildly

Townsville Airport averages 1,095.3 mm a year (Bureau of Meteorology 1991 to 2020 normals, via Wikipedia), most of it between November and April. February averages 338.1 mm and September just 9.9 mm. Wikipedia calls the year-to-year swing almost uniquely large for a climate this wet, so a gutter that coped last year may not cope this year.

Salt along the Strand and the islands

The Strand at North Ward looks across Cleveland Bay to Magnetic Island, about 8 km offshore. In Althea an estimated 90% of the island's buildings were damaged, and at Pallarenda nearly every building lost its roof. Near the water, salt goes after the screws and straps that hold a roof down, which is why the building code wants heavily galvanised or stainless structural steel on homes within a kilometre of the shoreline. For the roof sheets, BlueScope classes the Strand areas as exposed, so they get the same strict distance rules as a surf beach.

The roof jobs that come up most in Townsville

Repairs before the wet. Replacing rusted screws and sheets, resealing flashings and fixing leaks while the weather's dry. The QRA warns cyclone winds can push rain up valley gutters and under flashings even when the structure holds, and wet ceiling insulation then feeds mould. See roof repairs in Townsville.

Re-roofing older houses. Althea damaged roughly 500 of the city's 700 War Service Homes, and pre-1985 houses are still the ones the QRA worries about. A new roof is the moment to check battens and tie-downs. Our Townsville roof replacement and Colorbond roofing pages cover it.

Gutters and roof plumbing. A February downpour tests every joint and downpipe. Start with gutter replacement, gutter cleaning or roof plumbing.

Newer homes in the growth areas. Much of the city's expansion is heading west and north into the former City of Thuringowa, including Elliot Springs and the North Shore estate. Those roofs are built to current rules, so the job is mostly maintenance. If a newer roof leaks, the Queensland Home Warranty Scheme treats a defect that lets water in as a structural defect.

Heritage homes. North Ward has heritage-listed houses such as Selhurst and Kardinia. For anything on the Queensland Heritage Register, most changes need approval first, and that can include repairs.

Cyclone season and the days after

Queensland's cyclone season runs from 1 November to 30 April, but Get Ready Queensland says coastal towns should prepare all year. Never go up on a roof once a cyclone is on its way, or while it's wet. For storm damage emergencies call the SES on 132 500, and stay out of rooms where the ceiling sags. Afterwards, be wary of door-knockers: the Insurance Council says insurers won't send a tradesperson without telling you first.

What we'd do in Townsville

If your house was built before the mid-1980s, we'd get the roof framing checked the next time any sheets come off, not just the sheeting. The QRA also suggests a professional look every seven to ten years, because steel straps corrode and timber rots or gets termites. Book it for the dry months, when roofers aren't chasing leaks.

Questions

Straight answers.

Is my Townsville house built to handle a cyclone?
It depends mostly on when it was built. The QRA says homes built after the mid-1980s should have been designed for the wind speed at their site, while homes built before 1985 usually take more damage. A builder, engineer or certifier can tell you what your roof's fixings are actually up to.
Can I still get a Household Resilience Program grant?
No. The program closed to new applications on 2 October 2026, with final approvals for existing applications due by 31 May 2027. Any roofer still quoting it as a way to pay for your roof is out of date.
Will a new or tied-down roof cut my insurance?
Maybe, but nobody can promise it. Under the Cyclone Reinsurance Pool, insurers can get a discount of 30% on the wind part of their pool premium for a new roof, or 20% for a tied-down roof. Each insurer decides whether to pass that on, so ask yours before you budget for it.
How do I check a Townsville roofer's licence?
Search their name or number on the QBCC licensee register, or call the QBCC on 139 333. Building work over $3,300 needs a QBCC licence, though the Queensland Government has flagged changes to that threshold, so check the current figure. Plumbing and drainage need a licence at any value.
