Roof Cleaning Island Bay

If your Island Bay 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.

Island Bay roof cleaning from The Parade to the hill streets

Island Bay's houses split into two broad groups when it comes to cleaning. Down on the flat around The Parade and the beach, the 1920s houses and bungalows from the suburb's busiest decade of building have corrugated iron roofs facing straight out to Cook Strait. Southerlies carry salt off the water and leave it under the eaves, behind the spouting and along the sheltered side of each lap. Those are the places an iron or steel roof starts to corrode, and they are exactly the areas rain cannot rinse for you.

Climb the hill streets and the job changes. Later homes on the slopes can have tile or decramastic, they sit further from the spray, and moss becomes more of an issue than salt on the faces turned away from the sun. Tile is treated and given a day or two for the growth to die before a gentle wash. Any decramastic laid before asbestos was phased out gets tested first and is never water blasted.

For the beach-side homes, cleaning works best as a routine rather than a one-off. Steel roofs this close to the sea have shorter washing intervals in their warranty conditions, and a regular wash of the unwashed areas is far easier on the coating than a heavy clean every few years. Runoff is collected at the downpipes, because stormwater here ends up in the sea, and this stretch of coast includes the Taputeranga Marine Reserve around Tapu Te Ranga Island.

Local tip: Ask for the eaves and spouting undersides to be washed on your Island Bay home even in years when the roof itself looks clean.

Roof Cleaning in Island Bay: Local Conditions

Much of the south coast and the Miramar Peninsula sits close enough to the sea that salt collects on soffits, spouting undersides and sheltered roof areas. Regular washing of those spots matters more here than moss treatment does.

Salt builds up under eaves, around spouting and in other sheltered spots, and that is where corrosion starts on steel roofs.

Homes in Island Bay

Island Bay's 1920s houses and bungalows traditionally have corrugated iron roofs, and longrun corrugate keeps that character on a re-roof. Later homes on the surrounding hills can carry tile or decramastic. Homes near The Parade and the beach need coastal-grade steel and fixings, while hill homes need fixings suited to their wind exposure.

Roof Cleaning Island Bay FAQs

Does my Island Bay roof need cleaning if there is no moss on it?

Often, yes. Near The Parade and the beach, salt is the bigger threat, and it collects in sheltered spots that look clean from the ground. Washing those areas regularly keeps the coating protected and is usually part of a steel manufacturer's warranty conditions.

Could my Island Bay roof contain asbestos?

Super Six and other fibre cement sheet, some cement tiles and some decramastic roofs laid before asbestos was phased out can contain it. If yours could, we arrange testing before any cleaning and use low-pressure methods only.

How often should I clean my roof?

It depends on the roof and the exposure. COLORSTEEL sets manual washing intervals by environment category, and coastal sites need washing far more often than sheltered inland ones. Tile roofs under trees often need moss treatment every few years.
