The Basics

Common flat roof and membrane questions

I've been told I have a butynol roof. Does it have to be replaced?

If it's under about 15 years old and the seams are sound, a repair can be worthwhile. Past that, patches fail within a season or two because the membrane itself has lost flexibility. Send us photos and we'll give you an honest call. We'd rather do one proper job than three patches.

Can you lay the new membrane over the old one?

No, and be wary of anyone who offers to. Old membrane traps moisture against the substrate and hides rot. We strip it, inspect and repair the deck, then install new. It's the only way the warranty holds.

What does a membrane roof replacement cost?

Membrane replacement starts from around $160 per square metre. A typical Auckland home runs $15,000 to $25,000 depending on size, detailing and how much substrate repair is needed. Asphalt shingle reroofs are typically $20,000 to $30,000. Every quote is fixed, itemised and free.

What warranty do I get?

Two: the manufacturer's system warranty, which applies because we're certified applicators, and our 10-year workmanship guarantee. Both in writing at handover.

How long is my house exposed?

We only strip what we can re-lay the same day. Most residential membrane jobs take two to four days, and the roof is watertight every night.

Is this going to turn into a reclad?

Not without you knowing first. Substrate inspection is part of every job. If we find rot, we stop, show you photos and price the repair before going further. No surprises on the invoice.

More questions we get asked

TPO or torch-on: which one and why?

TPO is a single-ply sheet with hot-air welded seams, no flame, UV stable and the go-to for most residential flat roofs and decks. Torch-on is a heavier bitumen system, better suited to some commercial and heavy-traffic applications. We install both and recommend based on your roof, not on what's easiest for us.

Can you do the deck over the garage and the internal gutter in the same job?

Yes. Internal gutters, decks, balconies, parapet flashings and the main roof are usually one scope for us. Doing them together is cheaper than piecemeal and avoids joins between old and new work.

Why are you more expensive than the roofer who quoted long run?

Long run is a different product and often the wrong one for a flat or low-pitch roof. Under about 3 degrees of pitch it will pond and leak. Membrane is the correct system, and installing it to warranty standard takes certified applicators.

Why choose you over a big commercial roofing company?

No minimum job size, no call centre, no sub-crew. You deal with the licensed applicator who does the work, from the first site visit to handover. The big firms are built for factories and schools. We're built for Auckland homes and small buildings.

You don't have many Google reviews yet. How do I know you're any good?

Most of our work comes from other roofing companies and from the neighbours of jobs we've done, so our Google profile is thinner than our job list. We're happy to give you references from recent membrane and shingle jobs, and our Membrane Roofer of the Year award is a national, category-specific credential you can verify.

Do you do small repairs?

We do flat roof and membrane repairs across Auckland. For very small jobs a long way from Manurewa, travel makes it uneconomic and we'll tell you so upfront rather than overcharge you.

What areas do you service?

All of Auckland, from our base in Manurewa.
