Watertight where iron can't go
Rubber membrane is the solution for roofing flat and low-pitch areas, box gutters and decks: anywhere water moves too slowly for conventional long-run iron to shed it. Done properly, a membrane roof is a single continuous waterproof skin over the whole surface, protecting the interior of your home with no laps or fixings in the waterway.
Done poorly, membrane roofs are a liability, and Canterbury has plenty of history here. Earlier products like butyl rubber (Butynol) deteriorated in sunlight and leaked at their many glued seams. Modern TPO membrane solves both problems, but only if the installer is trained: seams are fused with hot-air welding, and that is a certified skill.
Why we install ecoTUFF TPO
Quality Roofing is a certified installer of ecoTUFF TPO, a copolymer of polypropylene and ethylene propylene rubber formed into a membrane sheet and reinforced with a heavy-duty polyester scrim. In practice, that means:
- Excellent resistance to weathering, temperature extremes and UV exposure (the Canterbury killer of older membranes)
- Wide rolls that minimise the number of seams on your roof
- Heat-welded joints that fuse into a single sheet, with no glue lines to age and fail
- Reinforcing scrim that resists punctures and foot traffic on decks
- A certified installation backed by the manufacturer
Where we use it
Flat and low-pitch roofs: additions, mono-pitch designs and mid-century homes where the pitch is below what long-run iron can safely handle.
Box gutters and internal gutters: a welded TPO lining turns the leakiest detail on many buildings into a continuous waterproof channel.
Decks and balconies: waterproofing over living spaces, with substrate replacement where the old deck has suffered, as in the before/after alongside.
Every membrane job starts with the substrate. We check falls, replace water-damaged ply and correct drainage before a single sheet goes down, because membrane over a bad substrate is a short-term fix.
