Ridge re-bedding, wind-damage repairs and re-roofs for Hillsborough homes on slopes above the Manukau.
Roofing in Hillsborough
- Mostly 1940s-70s homes
- Hillside sections
- Wind exposure
- Harbour edge
Hillsborough sits on the slopes south of Mount Roskill, running down toward the Manukau Harbour, with Hillsborough Road winding along its length and Waikowhai bush reserves near the coast. Plenty of houses here were sited for harbour views, which means they face straight into the prevailing weather. That single fact explains a lot of the roofing calls we get from Hillsborough: storm damage, loose ridges and flashings that have taken one westerly too many.
Homes in Hillsborough
Most homes date from the 1950s to the 1970s, a mix of weatherboard, brick veneer and some fibrolite-clad houses, many single storey but plenty split over two levels to follow the slope. More recent decades have brought infill houses, townhouses and some larger new builds on the view sites. Driveways are often steep and sections sloping, which affects access and how scaffolding is set up.
The roofs we work on here
Concrete tiles are very common, alongside decramastic and corrugated or trough-section iron on the later houses. On exposed faces, ridge and hip caps loosen as their mortar bedding cracks, and wind can then strip them or shift tiles. Decramastic rusts once the chip coating wears thin. Low-pitch roofs on split-levels can leak where roof planes step down. Typical work includes ridge re-bedding, tile replacement, restorations, and long-run re-roofing for roofs that have reached the end. Garage roofs tucked under the house are another regular culprit, since their membranes or low-slope iron rarely get looked at until water shows on the ceiling below.
Weather and exposure
Hillsborough's south and west-facing slopes take the brunt of storms coming in across the Manukau. Wind is the main stress, followed by salt carried on those winds, especially on houses closest to the harbour edge. Down near the bush reserves, shade and native trees add moss on roofs and leaves in spouting. Higher, open streets dry faster but suffer more wind uplift.
