Affordable leak repair
For roofs that leak, but do not need to be completely replaced yet.
The ORI membrane is installed over prepared roof areas to create a continuous waterproof layer. It is especially useful when leaks are coming from ageing metal roofing, roof laps, low-slope areas, rubber/membrane details or junctions that are expensive to rebuild.

FAQ
ORI Roof Waterproofing questions
Is this a replacement for a new roof?
No. It is a repair-first option for suitable roofs. OBS checks the roof first and will tell you if replacement is still the better direction.
What roof types can it suit?
It can suit selected metal roofs and rubber/membrane roof areas on homes, farm buildings, animal sheds, factories and warehouses.
How much cheaper can it be?
On suitable roofs, the repair path can be up to 70% cheaper than full replacement. Final cost depends on roof size, access, condition and preparation.
Does the membrane help with insulation?
Yes. The product includes an insulation layer, so it can add a thermal benefit while improving waterproofing on the repaired roof area.
Can OBS handle scaffolding and height work?
Yes. OBS can plan roof access, arrange scaffolding where needed and use height-work-certified personnel for suitable New Zealand roof-access requirements.
