Service · Membrane Roofing / Waterproofing
Durable membrane roofing and waterproofing.
Our Membrane Roofing Division is dedicated to elevating the standard of roofing solutions across Christchurch and beyond, combining the finest materials and cutting-edge technology to deliver unparalleled, flood-tested membrane systems.
Plain-English overview
What it is, who it’s for, when to call us.
Membrane roofing and waterproofing is how flat and low-pitch roofs, decks and below-grade structures are sealed against water. Our expertise spans a wide range of roofing methods, ensuring every commercial and industrial project is completed with precision and care, durable in any weather conditions.
Our innovative, sustainable membrane technology ensures exceptional durability, standing up to the harshest weather Christchurch and the wider Canterbury region can throw at it. Call us when you’re building or remediating anything that has to stay watertight, a commercial roof, an industrial deck or a podium over occupied space, or when an existing roof keeps leaking and nobody has found the source.
Common use cases
Where membrane roofing comes in.
Membrane roofing — TPO & PVC
Installing TPO and PVC membranes for durable, energy-efficient roofing that resists weathering, chemicals and UV exposure.
Liquid-applied membranes
Applying liquid membranes that cure to a seamless, waterproof barrier, ideal for complex roof shapes and detailed areas.
Torch-on roofing systems
Using torch-on membranes for a robust, weatherproof roof with excellent durability and resistance to extreme conditions.
Butynol roofing
Installing Butynol membranes for flexible, long-lasting waterproofing across diverse climates and roofing applications.
Warm roof systems
Constructing warm roofs with insulation above the waterproofing layer, improving thermal performance and energy efficiency.
Heat-reflective coatings
Applying reflective coatings that reduce heat absorption, lower cooling costs and enhance building energy efficiency.
Internal gutters
Installing and maintaining internal TPO guttering to manage roof drainage and prevent leaks and water damage.
Greywater retention
