Why Tauranga roofs get damaged where they do
South-westerlies do most of the work
Winds from the west and south-west prevail here. The airport's strongest recorded gust, 119 km/h, came from the southwest on 15 April 1969, and gusts over 96 km/h turn up on about 0.2 days a year. After a blow, look along the south-west edges, barge flashings and ridge line from the ground first.
Tornadoes hit narrow strips
A tornado at Mount Maunganui on 13 May 2015 damaged homes and Baypark Stadium, and another at Pāpāmoa on 27 June 2020 damaged some houses. The April 2026 tornadoes peeled back part of a Maungatapu roof and left five Welcome Bay properties deemed dangerous or insanitary. One street can need a new roof section while the next needs nothing.
Hail is rare, but it has been big
The airport averages just 1 hail day a year. Then in May 2009 a western Bay of Plenty hailstorm dropped stones from marble size to half the size of golf balls. Hail like that can dent longrun, crack brittle old tiles and split skylight domes, so get a roofer to look rather than assume all's well.
What a typical repair visit involves
On longrun (long metal sheets that run from ridge to spouting), it's usually replacing loose or rusted screws, re-fixing lifted sheet edges and resealing flashings around chimneys, vents and skylights. On concrete tile, it's swapping cracked tiles and rebedding or repointing ridge capping (relaying or refacing the mortar that holds the caps down).
Decramastic roofs (pressed steel tiles with a stone-chip coating) tend to dent or lose chips, and our decramastic repairs page covers that. Flat butynol roofs split at joints and corners; see butynol repairs. If the roof is older, keep in mind that WorkSafe says any home built before 1 January 2000 may contain asbestos, so nobody should drill, cut or water-blast a roof until that's ruled out. Our guide on whether your roof is asbestos explains how to check.
Storm damage, insurance and consent
House insurance is meant for sudden damage. The Insurance Council's own example is a tree falling on a roof. Wind and tornado damage to the house goes to your private insurer, because the Natural Hazards Commission (NHC) covers only your land after a storm. Rust, age-faded paint and general wear aren't sudden, so a policy won't pay for them. Photograph everything before temporary repairs, and see our guide to storm damage roof claims.
Most repairs don't need a building consent. Schedule 1 of the Building Act lets you repair and maintain with a comparable product, and replace parts with a comparable product in the same position. The exemption doesn't cover complete or substantial replacement of structural parts, or repairing a part that failed the Building Code's durability rules, for example by letting water in. If you're unsure, ask Tauranga City Council before work starts.
What makes a repair bigger or smaller
The size of a Tauranga repair depends on how many spots need work, whether matching tiles or sheets can still be found, how steep or high the roof is, and whether scaffolding or edge protection is needed. A good written quote lists each repair, the materials going in, any access equipment, and what's covered if the same spot leaks again. Our guide to reading a roofing quote shows what to look for.
What to ask a Tauranga roofer before they start
- Is this storm damage, and will you photograph each spot for my insurer?
- Are you fixing the cause, or sealing over the symptom?
- Are the replacement screws, flashings and fixings suited to my exposure zone near the coast?
- Is this a fixed quote or an estimate? Once you accept a quote, the roofer can't charge more unless the job changes; an estimate is only a best guess.
- Does any part of this need a building consent, and if so, who's the LBP?
What you can safely do, and what to leave
You can
- Scan the roof from the street or backyard with binoculars after a gusty day
- Check ceilings and the tops of walls for new stains after rain
- Take dated photos of any damage before anyone touches it
Leave to a roofer
- Anything that means standing on the roof, wet or dry
- Tarping a storm-damaged roof
- Replacing screws, sheets, tiles, ridge capping or flashings
Our take on Tauranga repairs
We'd get a lifted flashing or loose sheet fixed within days of a blow, before the next rain gets driven in under it, and we'd keep the roofer's photos with the insurance claim. If the same roof needs patching after every storm, ask the roofer straight out whether a section re-roof in Tauranga would make more sense than another round of patching.
