Butynol & TPO Deck and Roof Remediation

Specialist Butynol and TPO membrane remediation for decks, flat roofs and deck-over-living-space failures across the Bay of Plenty.

Failed membranes are one of the most common — and most damaging — building failures in New Zealand homes. Water gets behind the membrane, rots the substrate, and what looks like a small leak quietly destroys the structure underneath. BUCO removes failed Butynol and TPO membranes, corrects falls, replaces flashings, and reinstates decks and flat roofs the way they should have been built in the first place.

Over 1,500 projects delivered across Tauranga and the Bay of Plenty, including some of the trickiest deck-over-living-space and flat-roof remediation work in the region. We work with both Butynol and TPO, depending on what's right for the substrate, the spans and the design. LBP-licensed, Site Safe Gold, with internal make-good (linings, paint and flooring) handled in-house — so the fix doesn't end where the membrane ends.
