Why Rinocote Roof Armour?

Rinocote Roof Armour is a super tough, long-life roof membrane that will beautify your home, add value, and protect your roof against New Zealand’s harsh climate and extreme conditions for decades to come.


Rinocote has four unique roof membrane systems that can be applied to a range of substrates including: pressed metal tile, concrete tile and galvanised iron/faded steel.


For optimal performance and longevity, each roof type requires a specific coating system. Avoid companies who offer “ordinary paint” as the one solution for all roof types.


Rinocote is applied approximately 150% thicker than ordinary paint, providing optimal protection for your roof.

Is Rinocote Expensive?

No, renewing your roof in Rinocote Roof Armour generally works out to be half the price of a new total roof replacement, and in most cases not a lot more expensive than an average ordinary paint job.

Will this add value to my home?

Absolutely! A home with an attractive roof in good condition will sell more quickly and at a higher value than a house with a roof in poor condition.

Your roof is approximately a third of the exterior of your home and if not maintained will require costly replacement.


Many homeowners will renew their roof with Rinocote Roof Armour prior to selling their homes so they can price them at the top end of the market.

Yes, all roof substrates are repaired and cleaned before Rinocote Roof Armour is applied.
