Roof Washing North Shore

Moss and lichen on a the North Shore roof are more than a cosmetic problem. They hold moisture against the surface, which speeds up erosion of concrete tiles and keeps steel coatings wet for long periods. We kill the growth first so it can be removed gently, and some lichen residue is best left to weather away after treatment.

North Shore roof cleaning from the bays to Glenfield

North Shore roof cleaning depends on how close you are to the water. Along the bays from Devonport to Browns Bay, many homes are within about 500 metres of the coast and in the highest sea spray zone, so the work centres on washing salt off the eaves, the underside of the spouting and roof sections tucked out of the rain. Milford and Takapuna homes near the beach and Lake Pupuke fall into the same pattern. Older Takapuna villas often still have original chimneys, and we clear the debris that gathers behind them.

Inland, the jobs change. Glenfield and the older East Coast Bays streets have many 1960s and 1970s concrete tile and decramastic roofs. Concrete tiles there carry moss and lichen on shaded faces and need treatment before washing, while decramastic is tested for asbestos first and only soft washed. Albany's 1990s and 2000s homes have parapets and internal gutters, so we keep pressure low around junctions and clear outlets by hand.

Devonport and Northcote Point villas are usually iron or longrun corrugate, cleaned with a soft brush and attention to old fixings and laps. Exposed ridges on the East Coast Bays catch strong winds, and we note any lifted flashings or loose screws found while cleaning, with photos, so you can decide what to do about them. Runoff is captured on every job, as stormwater drains on the Shore lead to streams and the sea.

Local tip: If you live on the bays, ask for a washing schedule for the sheltered areas of your roof, because that routine is what COLORSTEEL warranty conditions rely on.

Roof Washing in the North Shore: Local Conditions

Large parts of the bays from Devonport to Browns Bay sit within about 500 metres of the coast, where salt builds up on soffits, spouting undersides and sheltered roof sections. Regular manual washing of those areas is part of keeping a COLORSTEEL warranty valid, and we schedule cleans to suit.

Roofs in the North Shore

Devonport and Northcote Point villas mostly started with corrugated iron, and many are now on longrun corrugate. The post-bridge suburbs of Glenfield, Browns Bay and the East Coast Bays have a high share of 1960s and 1970s homes with concrete tile or decramastic roofs, which are the most common tile to metal conversions we see. Albany's 1990s and 2000s houses often combine metal tile or longrun roofs with monolithic cladding, parapets and internal gutters, where the junction details matter more than the roof sheets.

How We Handle Roof Washing in the North Shore

We wash with low pressure and a soft brush, paying attention to valleys, laps, fixings and the sheltered areas rain never reaches. Debris is cleared from the gutters and taken away rather than left in the drains.

Pricing: every roof gets a free on-site measure and an itemised written quote, with a fixed price agreed before any work starts.
