Flat roof or internal gutter letting you down?
Restore it — don’t replace it.
Cohe’s Ultra Flex Pro delivers up to 20 years of waterproofing protection, at less the cost of a full reroof.
When coatings on flat roofs and internal gutters fail, the damage compounds fast – water ingress, ceiling staining, mould, structural deterioration, disrupted tenants.
The usual answer is a full reroof which is expensive, disruptive and often unnecessary.
Our Ultra Flex Pro is a system developed specifically for flat roofs and internal gutters
A flexible, antimicrobial, UV-resistant waterproofing membrane, formulated and manufactured in New Zealand for New Zealand conditions. Applied as a seamless liquid membrane over your existing surface, it bonds to metal, concrete, modified bitumen, EPDM, PVC, TPO, and timber, without tear-off of existing, heavy equipment or structural disruption.
Up to 20-year waterproofing warranty
Backed by Cohe as the manufacturer. One company responsible for the product and the install.
Manufactured in Auckland, New Zealand
Formulated for NZ UV levels, temperature variation, and weather conditions. Not adapted from an overseas product.
Fully managed supply and install
From initial assessment through to warranty registration. One point of contact throughout
Why it works
Moves with your property
Buildings expand and contract daily. Rigid coatings crack under stress. Ultra Flex Pro maintains permanent flexibility, accommodating substrate movement and thermal cycling without compromising the waterproof seal.
Built-in UV protection
New Zealand's harsh UV conditions destroy imported products within years. Ultra Flex Pro is formulated locally with advanced UV absorbers that prevent yellowing, crazing, and degradation.
Resists biological growth
Silver ion technology doesn't just keep your roof clean, it stops moss, lichen, and mould from keying into the membrane and breaking it down.
See the difference
One company. From product to warranty
Most waterproofing jobs involve multiple parties. When something goes wrong, they may point at each other and the problem takes time to resolve.
We manufacture Ultra Flex Pro in New Zealand and manage installation through our certified applicator network. Your warranty isn’t split, it sits with one.
We’ve been working in remedial waterproofing for over 10 years, across residential, commercial, and body corporate properties throughout New Zealand. You can count on us ti tell you upfront if restoration isn’t the right solution for your situation.
