Exterior cleaning in Pukekohe

Pukekohe is at the far southern edge of the area we cover, and its weather is noticeably different from the city’s. It’s wetter, calmer and gets less sunshine than most of Auckland, which is great for the market gardens on its volcanic soils and less great for anything that has to dry out after rain, including your roof.

Why do Pukekohe roofs and walls stay damp for so long?

Three things combine. NIWA’s normal annual rainfall at Pukekohe is about 1,283 mm, roughly 146 mm more than central Auckland, with each winter month getting around 140 to 150 mm. The southern parts of the region around Pukekohe also get the least bright sunshine in Auckland, and Pukekohe has the lowest average wind speed of NIWA’s regional stations, about 9 km/h against 18 km/h at the airport.

More rain, less sun and little wind means surfaces dry slowly. That is the general pattern moss, lichen and algae like best, so shaded roof slopes and south walls here tend to go green sooner than the same house would in the city. A spray-applied roof moss and lichen treatment kills the growth, and the weather clears it over the following months.

How important are clear gutters in Pukekohe?

Very, because heavy rain does happen. NIWA records a January 1999 storm in which Pukekohe received three times its normal January rainfall in two hours, an event it rates as rarer than once in 150 years, which flooded homes and destroyed crops. You can’t plan for a storm like that, but you can make sure the gutters and downpipes aren’t already half blocked when one arrives.

A gutter clean in late autumn, before the wet months, is the most useful timing. Homes with big trees nearby may need a second clean in spring. If your downpipes feed a rainwater tank, mention it when you book so the crew can keep debris and any roof treatment out of the tank.

What else do Pukekohe homes book?

A house wash is the other regular job, usually in spring once the wet season eases. Because walls here stay damp longer, mould on the shaded side comes back sooner, so a yearly soft wash suits most homes. Paths, patios and driveways that go slippery through winter are cleaned with a surface cleaner, with the wash water kept out of the stormwater system.

Older homes in town follow the same rules as anywhere else in Auckland: assume lead in the paint of any pre-1990 home and the chance of asbestos in anything built before 2000, so older walls and roofs are cleaned at low pressure.

Questions from Pukekohe

Do you cover the rest of Franklin?

We quote in Pukekohe and nearby, and we’ll tell you straight away whether we can reach smaller towns further out. Pukekohe is a long way from our North Shore base, so grouping a few jobs into one visit, such as gutters, roof treatment and a house wash, usually makes the trip worthwhile for everyone.

Is roof treatment safe if I collect rainwater?

It can be, with care. Roof treatment products carry label instructions about rainwater tanks, typically asking for the tank to be disconnected for a set period or amount of rain. Tell us about the tank when you book, and the crew will disconnect and reconnect the downpipes as the product label requires.
