Is your roof leaking, fading or rusting? It may not need replacing.
A worn roof doesn’t always mean a new roof. In many cases, a Cohe coating system can seal, protect and restore what’s already there – for less cost and far less disruption than a full re-roof.
Lower cost
Restoring your existing roof is typically a fraction of the cost of replacing it.
Less disruption
No tear-off and no heavy equipment. Most projects are finished in around 5 days, depending on weather and roof pitch.
Long-term protection
Flexible, UV-resistant coatings that move with your building and resist moss, mould and lichen.

Your questions answered
How much does roof restoration cost?
Every roof is different, so we quote each project individually based on size, roof type and condition. Restoring your existing roof is typically a fraction of the cost of a full re-roof. Quotes are free and no-obligation.
Is my roof suitable for coating?
Most roofs are, including long run iron, tiles, flat roofs, torch-on, butyl and EPDM. Some roofs are too far gone to restore, and we’ll tell you honestly if that’s the case. The quickest way to find out is to send us a photo.
How long does it take?
Most projects are completed in around 5 days, depending on weather, roof pitch, size and preparation. We’ll give you a clear timeline with your quote.
Will it disrupt my home or business?
Very little. There’s no tear-off and no heavy equipment, and most commercial projects go ahead without interrupting day-to-day operations.
Do you take on commercial and body corporate projects?
Yes. We work with property managers, body corporates and building owners on projects of all sizes, from apartment roofs and internal gutters to carparks. Select your property type in the form and we’ll be in touch.
What does the warranty cover?
You’ll receive a project-specific waterproofing warranty of up to 10 years with C200, or up to 20 years with Ultra Flex Pro. Because Cohe manufactures the products and manages the installation, the warranty comes directly from us.
Can I still collect rainwater from my roof?
Our systems are suitable for rainwater collection once fully cured.
Do you work with asbestos roofs?
Yes. We can encapsulate asbestos roofing, sealing it in place without the cost and risk of removal.
Do you cover my area?
We have a team of 100 installers across New Zealand. Tell us where you are in the form and we’ll confirm.
