Roofing in Mangere Bridge: Coastal Re-Roofs & Flashings

Roofing in Mangere Bridge

• Mostly 1940s-70s homes
• Coastal exposure
• Harbour edge
• Wind exposure

Mangere Bridge is the small village at the northern tip of the Mangere peninsula, looking across the Manukau Harbour to Onehunga. The old bridge is now a walking and fishing spot, Mangere Mountain rises behind the shops, and the coastal walkway draws people out along the water. It feels quieter than the rest of Mangere, and the harbour shapes just about everything to do with roofs here.

Homes in Mangere Bridge

Homes in Mangere Bridge are mostly 1950s to 1970s, with weatherboard and brick bungalows, some state houses and a handful of older cottages near the village. Waterfront and elevated streets have attracted renovations and newer architectural homes over the last twenty years. Sections around the mountain slope gently, and some properties near the coast are small and tightly spaced, which can make access for scaffolding and materials a consideration.

The roofs we work on here

Corrugated iron, concrete tile and long-run are the common coverings, with some flat membrane roofs on renovated and newer homes. Salt air is what sets the pattern of failure. Steel roofs corrode first at cut edges, laps, fixings and under-eave areas that rain never washes clean. Galvanised nails and older flashings rust long before the sheets themselves. Concrete tiles weather faster and gather lichen. Re-roofing in a coastal-rated steel, replacing corroded flashings and switching to stainless or appropriately rated fixings are the typical jobs. Spouting corrodes quickly here too.

Weather and exposure

This is genuinely exposed coastline. Wind comes straight across the Manukau with nothing to slow it, and salt spray settles on roofs closest to the water. Homes on the higher ground near the mountain catch more wind again. Regular rain washes the exposed parts of a roof, but sheltered areas under eaves, behind parapets and beneath overhangs build up salt and corrode quietly.
