Expert Butynol & Flat Roof Repairs in Christchurch
Christchurch is hard on roofs. Intense UV, hot nor'westers and frosty winters all wear down butynol membranes, seams and flashings — and once water gets in, it quickly damages ceilings, framing and insulation.
We specialise in butynol roof repairs in Christchurch: finding leaks, re-sealing joints, patching splits and replacing membranes that have reached end of life. Our team also handles metal roof repairs, nail to screw conversions and full re-roofing, so one call covers the whole roof.

Butynol, Membrane & Flat Roofs
Butynol Leak Repairs
We trace leaks to the source — seams, outlets, flashings or punctures — and make the roof watertight fast.
Butynol Membrane Replacement
When the membrane has reached end of life we strip, check the substrate and install a new butynol or TPO system.
Patching & Seam Re-Sealing
Splits, blisters, lifted joints and punctures repaired with professional-grade materials for a seamless finish.
Flat Roof & Deck Waterproofing
Flat roofs, decks, balconies and internal gutters waterproofed with GAF and SEALCO approved membrane systems.
Metal Roofing & Re-Roofing
Metal Roof Repairs
Rust treatment, sheet replacement, ridge capping and flashing repairs on corrugated and long-run roofs.
Nail to Screw Conversion
Old nailed roofs upgraded to modern screw fixings — far better hold against Canterbury nor'westers.
Re-Roofing
Complete roof replacement: removal, structural check, new roofing, clean-up and workmanship warranty.
Gutters, Tiles & Downpipes
Cracked tiles, leaking gutters and blocked downpipes repaired before they cause interior damage.
Why Christchurch Roofs Leak
Most roof leaks we see in Canterbury come down to the same five causes. Catching them early is far cheaper than repairing water damage later.
High UV exposure
Canterbury's clear skies bake dark butynol membranes, drying seams and causing cracking over time.
Hot nor'westers
Strong, dry winds lift weak joints and loosen nailed roofing sheets and flashings.
Frosty winters
Freeze-thaw cycles expand small splits and open up failing laps and penetrations.
Building movement
Settlement and seismic movement stress membranes at upstands, parapets and junctions.
Ponding water
Poor falls and blocked outlets leave water sitting on flat roofs, accelerating membrane failure.
How It Works
Simple, transparent and no surprises.

Christchurch Roofing FAQs
Do you do butynol roof repairs in Christchurch?
Yes. Membrane Roofing Applicators repairs and replaces butynol roofs across Christchurch and greater Canterbury, including leak detection, seam and joint re-sealing, patching of splits and punctures, blister repair, flashing repairs and full membrane replacement.
How long does a butynol roof last in Christchurch?
A correctly installed butynol roof typically lasts around 20 to 30 years. In Canterbury, strong UV, hot nor'westers and frosty winters speed up ageing, so roofs over 15 years old should be inspected regularly. Fixing small failures early is the best way to extend the life of the membrane.
Should I repair or replace my butynol roof?
Most localised problems — leaks, splits, punctures, lifted seams and failed flashings — can be repaired without replacing the whole roof. Replacement is usually only recommended when the membrane has widespread deterioration or the substrate has been damaged by long-term water ingress. Our free inspection tells you which option makes sense.
Do you also repair metal and long-run roofs in Christchurch?
Yes. As well as butynol and membrane roofs, our Christchurch team handles metal roof repairs, corrugated and long-run roofing, rust treatment, flashing and ridge capping, nail to screw conversions, re-roofing, tile repairs and gutter work.
Can you fix a leaking roof urgently?
We prioritise active leaks. Call 027 209 1839 and we will arrange the fastest available inspection to find the source of the leak and make the roof watertight.
Are roof inspections and quotes free?
Yes. Roof inspections and written quotes in Christchurch are free and there is no obligation to proceed.
Which membrane systems do you use?
We install and repair butynol, TPO, PVC, EPDM and torch-on membranes, and work with approved membrane systems from GAF and SEALCO.
