The roof will be waterblasted to remove all dirt, loose and flaking material.  If moss and mould is present, the roof will be treated with Kowhai Koklean Green, a slow release, biodegradable, antifungicide treatment before applying the Kowhai TileCoat Coating System.

All loose nails will be removed and refixed with screws.  All ridges, valleys and flashings will be checked and repaired or replaced as required.

Any areas of red or white rust will be treated with a rust converter or anti-corrosive primer to hold and prevent any further rusting.

The Kowhai IronCoat Colourcoat will then be applied.  IronCoat is a 100% acrylic, high build, made to the colour selected from our Kowhai Colour Chart.
