If your Epsom home has a COLORSTEEL roof, the warranty depends on washing the areas rain does not reach, such as under eaves and around gutters. The harsher the environment, the shorter the washing interval. We clean those sheltered areas, laps and fixings with a soft brush and a cleaner that is safe for the coating.
Epsom roof cleaning: big trees, big roofs and chimney valleys
Epsom's large early 20th-century homes sit among established gardens and big trees, which is exactly what moss and lichen like. Shaded roof faces stay damp, and leaves pile up in valleys and against chimneys, damming water where it should run off. A clean here usually starts with clearing the valleys, the spouting and the uphill side of each chimney by hand, then a biocide treatment on the growth before any washing.
The roofs are larger and more complicated than most. Hips, valleys and dormers create many sheltered corners that rain never rinses, so we work through them one at a time. Most villas and bungalows here have corrugated iron or longrun corrugate, which takes a soft brush and low pressure, with attention to the laps and old fixings. Some later homes have concrete tile or decramastic, and the latter is always checked for possible asbestos before anyone touches it. Where valleys meet dormers, debris builds into small dams, so those corners are cleared by hand before any product goes on.
Epsom is inland, so salt is generally less of a factor than on the harbour edges, though we still confirm the exposure for every address. Runoff from the treatment is captured so it does not reach the stormwater drains or the garden beds, which on established Epsom sections often run right up to the house. If the growth is heavy, we tell you up front that a second treatment may be needed.
Local tip: Ask for the uphill side of each chimney to be cleared during a clean, because leaves trapped there are a common cause of water backing up under the flashings on Epsom villas.
Roof Washing in Epsom: Local Conditions
Leafy streets in Remuera, Epsom and Mt Eden keep shaded roof faces damp and drop leaves into valleys and gutters, so moss and lichen are the usual targets on the isthmus. Harbour-edge homes in Parnell, Remuera and Onehunga also collect salt in sheltered areas that need regular washing.
Villa and bungalow roofs are usually steel corrugate, which we clean with a soft brush and a coating-safe cleaner rather than high pressure.
Homes in Epsom
Epsom's large villas and bungalows were mostly built with corrugated iron, and many have been re-roofed in longrun corrugate, which keeps the traditional look. Some later homes carry concrete tile or decramastic. Bigger houses mean bigger, more complex roofs, with hips, valleys, dormers and chimneys that all add cutting and flashing time. Disused brick chimneys are a frequent leak source, and removing one below the roofline can be a permanent fix. Older roofs may also have sarking boards, which can often stay under new underlay.

Roof Washing Epsom FAQs
How long does moss treatment take to work on a shaded Epsom roof?
Some treatments take up to 48 hours to kill the growth, and thick moss under big trees may need a second round. Lichen is slower to let go, so any faint marks that remain are usually left for the weather to finish.
How much does roof cleaning cost in Epsom?
It is quoted on the roof area and type. The amount of growth, the need for treatment and a return visit, pitch, height and access, runoff control and whether you want the gutters cleared all affect the price.
Does moss damage a roof?
Moss holds moisture against the surface, which speeds up erosion of tiles and keeps steel coatings wet. It also blocks gutters and valleys.
