Roof repairs in Hamilton
Repairs are most of the work we do across Hamilton, and every repair below is on a long run or metal tile roof. The full list of roofing services we offer also covers spouting and downpipes.
01
Roof leak repairs
We trace roof leaks from the ceiling stain back to where the water gets in, which is often a metre or more upslope. Water runs along the purlins and underlay before it drops.
On long run iron the usual causes are lifted nails, perished washers and rust at the end laps. We swap failed fixings for new screws and seals and replace rusted sheets that will not take a patch.
Note whether the drip comes in heavy rain or on still, cold mornings. The second is often condensation.
02
Flashing, valley and flue repairs
Flashings fail before roof sheets do, so most of the leaks we fix sit at a flue, a skylight, a valley or the apron where the roof meets a wall.
Sealant smeared over a lifted flashing lasts a season at best. We refit or replace the flashing in folded COLORSTEEL to match your roof and seal it to the sheet profile.
Tell us if the leak started after a flue, skylight or solar panels went in. The flashing around that job is the first place we look.
03
Metal tile roof repairs
Our metal tile roof repairs cover lifted tiles, loose ridge caps, worn chip coating and leaks in the valleys.
Pressed metal tiles interlock and are nailed through the front edge into the batten, so one lifted tile lets wind under its neighbours. We re-fix or replace single tiles and ridge caps with matching profiles where they are still made.
A photo of your tile profile helps us check supply before the visit.
04
Rusted sheet and fixing replacement
Rust on an older long run roof starts where water sits, under lapped joints, around fixings and on the lower sheets above the spouting. Replacing those sheets and fixings keeps the roof going for years without a full reroof.
Once rust has spread across more than a few sheets, patching stops being good value. At that point we quote the repair and a full roof replacement side by side so you can compare.
05
Spouting and gutter repairs
Blocked or sagging spouting looks like a roof leak from inside. Water backs up behind the fascia, runs into the soffit and stains the ceiling near an outside wall.
We reset brackets for a steady fall, reseal joints and replace corroded downpipe outlets. Where a run is past saving, our spouting and gutter replacement crew fits new spouting in matching COLORSTEEL.
Not sure which repair your roof needs?
We inspect the roof for free, find where the water gets in and give you a written quote before any work starts.

Roof replacement and reroofing in Hamilton
When repairs stop holding, we replace the roof covering and keep the house frame. Every roof replacement we do includes new underlay, new flashings and new fixings.
01
Long run roof replacement
Long run COLORSTEEL is the roof we fit most often, because it runs in single sheets from ridge to spouting on most Hamilton house roofs. Fewer end laps leave fewer places for water to get in.
A long run roof replacement in Hamilton keeps the house dry while the work happens. We strip one section at a time and close it in before we leave site that day.
02
Metal tile roof replacement
A metal tile roof replacement suits owners who like the look of a tiled roof and want a lighter one. Pressed metal tiles weigh far less than concrete tiles, which takes load off an older frame.
We lay them on new battens over new underlay, with matching ridge, barge and apron trims. Pick the profile and colour at the quote stage, because the tiles are ordered for your roof before the start date.
03
Concrete and decramastic tile conversions
Our answer to a concrete or decramastic tile roof that keeps leaking is a conversion to pressed metal tiles or long run iron. We do not patch those tiles.
Cracked concrete tiles and decramastic tiles losing their chip both convert well. The old tiles and battens come off, the timber gets checked, and the new roof goes on over fresh underlay.
A lighter roof feels wind uplift more, so we upgrade batten fixings that fall short.
New roofs and roof maintenance in Hamilton
New roof installation
We install long run and metal tile roofs on new houses, extensions and garages for Hamilton builders and owner-builders.
Hamilton keeps building. Rototuna North went from 225 private dwellings at the 2018 Census to 840 at the 2023 Census, and Flagstaff South grew by about half.
Send us the plans and the roof pitch. We price the roofing, flashings and labour from the drawings and book the install around your builder's programme.
Roof inspections and maintenance
House buyers book our roof inspections before going unconditional, and owners book one once a roof passes about 15 years. We check the coating, fixings, flashings, valleys and spouting, then say what needs doing now and what can wait.
Maintenance means clearing valleys and spouting, re-fixing lifted screws and resealing flashings. COLORSTEEL warranty terms also ask owners to wash areas the rain does not reach, such as under the eaves.

What moves the price of a Hamilton roof
Roof size and shape
Hips, valleys and dormers add cutting, flashings and hours on the roof.
What comes off
Concrete tiles take longer to strip and cart away than old iron.
Timber under the roof
Rotten battens or purlins found during the strip get replaced before new roofing goes on.
Flues, skylights and solar
Every penetration through the roof needs its own flashing.
Height and access
Two-storey houses and steep sections need more scaffolding and edge protection.
Spouting at the same time
New spouting during a reroof shares the scaffold hire with the roof.

500+ roofs and 20+ years on Waikato roofs
We have completed more than 500 roofs across Hamilton and the Waikato. Our roofers bring more than 20 years of trade experience, and the business has worked across the Waikato for over a decade.
Each section closed the same day
No part of your roof is left open overnight during a reroof, whatever the forecast says.
New underlay on every reroof
Underlay carries condensation and wind-driven rain out to the spouting. We fit new underlay on every reroof, including roofs where the old layer still looks sound.
Before and after roof replacements in Hamilton
Hamilton damp homes, condensation and roof leaks
At the 2023 Census, 18.8% of occupied homes in Hamilton City were reported as always or sometimes damp, close to 10,000 households. A damp patch on a ceiling under the roof space is either a leak or condensation. The two need different fixes.
Condensation forms when warm, moist air from inside the house meets the cold underside of a metal roof on a clear night. Roof underlay catches those drops and runs them out to the spouting. On older Hamilton roofs we often find the underlay torn, sagging or missing, and the ceiling stains then look exactly like a leak. New screws will not stop condensation. New underlay, better ceiling insulation or more ventilation will.
A true leak follows rain. The stain grows after each heavy or windy fall, and it often sits under a flashing, a valley or a rusted lap. If you can, photograph the stain on a dry day and again after rain before we visit.
Hamilton City had 64,890 private dwellings at the 2023 Census, up 11.6% from 2018, so the roofs we work on range from new Rototuna builds to older houses now on their second roof. We wrote up the roof problems we see most across the Waikato for owners who want to check their own roof first.
