When to book in Ngaio
Late summer into autumn is the best window for a Ngaio roof — dry enough for the biocide to bind, before winter rain.
From hillside homes above the gorge to properties near the railway, we treat concrete tile, long-run iron and Colorsteel without high-pressure damage. Pair roof treatment with gutter clearing — tree debris in Ngaio gutters is almost always part of the job.
