How long does roof paint last in New Zealand's UV conditions?
A properly applied professional roof painting job using high-quality roof paint typically lasts ten to fifteen years in New Zealand UV conditions. Surface preparation quality and the coating system chosen are the two biggest factors in longevity.
Do you provide rust treatment and leak repairs before painting?
Yes. Rust treatment and minor leak repairs are completed as part of the roof painting project preparation stage on every job. Painting over untreated rust or active leaks shortens the life of the coating significantly.
What is the best type of paint to use for concrete tile vs. corrugated iron roofs?
Concrete tile roofs need a breathable, flexible coating that allows moisture to escape without lifting. A corrugated iron roof needs a metal-specific primer and topcoat system that handles expansion, contraction, and rust inhibition across New Zealand conditions.
Does roof painting help with home insulation or solar heat reduction?
Yes. Light-colored, high-quality roof paint reflects solar heat rather than absorbing it, which reduces heat transfer into the ceiling space. This is particularly effective on corrugated iron roof surfaces that heat up quickly during Auckland summers.
