TPO membrane roofing for Auckland flat roofs and decks, by certified applicators

The sheet is fully bonded to the deck with a spray-applied adhesive, and every seam is hot-air welded, which makes the join as strong as the sheet. Seams that rely on glue or tape alone give up long before the membrane does, and seam failure is the single most common reason we get called to a flat roof.

TPO needs no open flame at any point during installation, which suits occupied buildings and roofs close to timber framing.

The light surface reflects heat instead of absorbing it, which matters on a roof directly above a living space, and TPO is UV stable so it does not go brittle the way older membranes did.

Flat and low-pitch roofs, decks, balconies, parapets and internal gutters. Walk-on grades take artificial turf, tile or timber over the top, so a TPO deck can be a usable outdoor space rather than just a waterproof lid.

It suits new builds and extensions as readily as replacements, and because the sheet is light it does not add meaningful load to an existing structure.

The membrane out in the open field rarely fails. Roofs leak at the junctions, so that is where the time goes: upstands taken high enough for the exposure, outlets sized to the catchment with an overflow, penetrations collared and welded rather than sealed, and parapet caps dressed in properly.

Because we are certified applicators, the manufacturer's system warranty applies on top of our own 10-year workmanship guarantee. Both are handed over in writing.
