Roof Cleaning Mt Victoria

If your Mt Victoria home has a COLORSTEEL roof, the warranty depends on washing the areas rain does not reach, such as under the eaves and around the spouting. The harsher the exposure, the more often that needs doing. We clean those sheltered areas, laps and fixings with a soft brush and a coating-safe cleaner.

Mt Victoria cottages: cleaning old iron, lean-tos and hidden gutters

A typical Mt Victoria roof is really several roofs. Behind the original 19th century cottage or villa there is often a lean-to, a later addition and an internal gutter where two sections meet, and every one of those junctions collects silt, leaves and moss. When we clean here, we spend as much time on those meeting points as on the open sheets, because a blocked internal gutter on an old house sends water inside rather than over the edge.

Position on the slope changes the job. Houses up on the ridges are taller and catch the full wind, so treatment is applied on a calm day and ladders are set with care. Down in the hollows around Brougham Street and Austin Street, roofs are lower and hemmed in by neighbours, which keeps them shaded and damp and gives moss a head start. Trees on the Town Belt above add needles and leaves to the roofs closest to it.

Original corrugated iron carrying several coats of paint is cleaned at low pressure only, working along the ribs so water is not driven back up under the laps. If paint is lifting or rust is showing at the nail heads, we photograph it so you can decide whether a repaint is due. Narrow side yards and little off-street parking mean gear is carried in, and runoff is kept off neighbouring sections.

Local tip: Ask us to check the internal gutter between your cottage and its lean-to at every clean, since that is where Mt Victoria roofs most often overflow.

Roof Cleaning in Mt Victoria: Local Conditions

In Kelburn and Thorndon, mature trees and the shade of steep hillsides keep some roof faces damp for much of the year, which suits moss and lichen. Many central villas have old painted iron, which needs a gentle clean so the existing coating is not lifted.

On hillside sections, runoff heads downhill fast, toward neighbours, banks and drains.

Homes in Mt Victoria

Corrugated iron is the original roof on most Mt Victoria houses, and longrun corrugate keeps that look on a re-roof. Decades of additions mean many roofs have junctions between old and new sections, internal gutters and lean-tos, which is where leaks tend to start. Taller houses on the ridges need more scaffolding, while houses in the hollows are often hemmed in by neighbours.

Roof Cleaning Mt Victoria FAQs

Can you clean the roof of a Mt Victoria cottage that sits hard against the next house?

Yes. We work from your side of the boundary, keep runoff and debris off the neighbouring roof, and tell you beforehand if we need to step onto a shared gutter or parapet so you can talk to your neighbour first.

How long until the moss dies after treatment?

It depends on the product and how heavy the growth is. Some products take a couple of days to work, heavy growth may need a second treatment, and lichen residue can take longer to weather away.

Can you clean a roof before painting it?

Yes. Cleaning and treatment are the first stages of every roof painting job we do, and we also clean on its own as maintenance.
