Roof Cleaning Miramar

If your Miramar 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.

Miramar roofs: the sheltered basin and the salty hillsides

Miramar's flat basin was once a lagoon, and the homes that now fill it are more sheltered than most on the peninsula. Shelter is a mixed blessing for a roof. The ring of hills keeps some of the wind off, but that also means fewer gusts to clear debris and more salt left sitting on steel or iron where rain cannot reach it. With the harbour and Cook Strait close on every side, even a basin roof gets a regular dusting.

Up on the surrounding hills, roofs face the opposite problem, with wind from the airport side driving salt and grit into laps and around fixings. Many Miramar homes date from the tram era or from the state housing that started here in 1937, with corrugated iron, concrete tile or decramastic roofs. Each gets its own method: a soft brush along iron ribs, treatment left to work on porous tile, and testing before any work on decramastic or fibre cement that could contain asbestos.

For steel roofs a few hundred metres from the water, manufacturers set shorter washing intervals for the unwashed areas, and we follow those conditions so the coating stays protected. Runoff is captured rather than sent into the stormwater, which reaches the sea quickly from a peninsula this small. Before anyone walks on a tile or decramastic roof, we check for cracked or loose pieces, because stepping on a weak spot can do more harm than the moss ever did.

Local tip: If your Miramar home faces the airport or the strait, wash under the eaves and spouting more often than the open roof, since that is where salt sits longest.

Roof Cleaning in Miramar: 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 Miramar

Miramar's older homes from the tram era traditionally have corrugated iron roofs, and its state houses from the late 1930s onwards were roofed in tile or iron. Mid-century homes can carry concrete tile or decramastic, which are common tile to metal conversions. Homes on the surrounding hills have more exposed roofs, while those in the basin are more sheltered but still within reach of salt air.
