WATERPROOF MEMBRANES
TPO MEMBRANE ROOFING
Keep the weather outside, where it belongs. DCM Roofing provides TPO membrane roofing for homes and commercial buildings across Christchurch and Canterbury, with practical solutions for new roofs and roof replacements.
A SMART WATERPROOFING SOLUTION FOR YOUR HOME OR BUSINESS
Planning a new build with a low-pitched roof? Updating a commercial property? Or dealing with an older roof that has seen better days? TPO membrane roofing could be the answer.
TPO stands for Thermoplastic Polyolefin. It’s a flexible roofing membrane that creates a waterproof covering, particularly suited to flat and low-pitched roofs. The overlapping edges are welded together using hot air, creating secure seams that help keep water out.
We’ll take a look at your roof, talk through your plans and help you decide whether TPO is the right fit.
PROTECTION THAT LASTS
TOUGH ON WEATHER. SMART ON YOUR ROOF.
Your roof has a big job to do, from handling summer sunshine to keeping out winter rain. TPO membranes such as Viking Roofspec’s Enviroclad combine a reinforced sheet with resistance to UV exposure. Wide rolls reduce the number of seams, while heat-welded joins create a continuous waterproof covering. There’s a choice of colours too, so a practical roof can still look the part.
BEYOND THE ROOF
WATERPROOFING FOR BALCONIES
AND FLOATING DECKS
A balcony or deck above a living space needs dependable waterproofing underneath. Suitable TPO systems can provide a waterproof layer beneath floating decks, helping protect the rooms below. The membrane sits beneath the finished decking surface, with drainage and detailing planned as part of the system. Talk to us about your outdoor space and we’ll help work out a suitable solution.

Frequently Asked Questions
WHAT IS TPO ROOFING?
TPO is a flexible waterproof membrane used to cover roofs. Its full name is Thermoplastic Polyolefin, but we’re happy to stick with TPO!
IS TPO THE SAME AS BUTYNOL?
No. They both provide waterproofing, but they are different materials. Butynol is a synthetic rubber membrane, while TPO is a thermoplastic membrane with heat-welded seams.
IS TPO SUITABLE FOR MY ROOF?
It’s particularly suited to flat and low-pitched roofs. We’ll check your roof’s condition, design and drainage before recommending the right system.
DOES MY EXISTING ROOF MEMBRANE NEED TO COME OFF?
Not always. Some fleece-backed TPO systems can be installed over suitable existing membranes. We’ll assess what’s underneath before recommending an overlay or replacement.
DOES TPO COME IN DIFFERENT COLOURS?
Yes. Products such as Viking Enviroclad come in several colours, including white, grey and darker shades. We can talk you through the options.
CAN I USE TPO ON A DECK?
Suitable TPO systems can waterproof beneath floating decks. If you need an exposed surface to walk on, let us know so we can recommend an appropriate decking system.
