On Johnsonville roofs we look for rust through the paint at laps and eaves, leaks that move or return after repair, popped or corroded fixings, decramastic shedding its chip, tiles that keep cracking and underlay that has gone brittle. One of those usually means a repair. Several together usually mean the roof is near the end.
Replacing the roof on a Johnsonville state house
Between 1938 and 1956, 329 state houses were built in Johnsonville, starting in Bould Street on the former Native Reserve between Broderick Road and Fraser Avenue. They were built to standard designs, and their roofs, underlay and spouting have been on the house for well over half a century. That shared design is helpful: the roof shapes are simple and predictable, so once one is measured the quote is clear, and a COLORSTEEL re-roof suits them well. The timber under the roofing is the main unknown, and it is checked once the old sheets are off.
Further out, towards the base of Mt Kaukau and over the hill to Newlands, later homes carry concrete tile, decramastic or longrun steel, and infill units add low-pitch roofs. On the infill units, a leak is more often a flashing or penetration fault than a worn-out roof, so we check those before talking about replacement. Where a later home has decramastic, a sample is tested for asbestos at the start.
Johnsonville sits in a basin at the top of the Ngauranga Gorge, on the high ground beside the Wellington Fault, and homes on the basin slopes are exposed. The zone recorded for the property sets how the new roof is fixed. Where a tile roof is replaced with steel, the weight saving is real, and the lighter roof is held down to suit that zone. Downpipes on sloping sections go to stormwater throughout.
Local tip: If you own one of the older Johnsonville state houses, look in the roof space for brittle or torn underlay, because on a roof this age it can fail before the iron does.
Roof Replacement in Johnsonville: Local Conditions
Karori, Ngaio and Khandallah carry roofs from almost every era, from 1920s bungalows to 1960s weatherboard homes, while Churton Park's 1970s and later houses are only now reaching their first replacement. Hillside access is a big part of the cost here, so planning ahead pays.
State houses were built with tile or corrugated roofs, and many still have the original.
Homes in Johnsonville
Johnsonville's state houses from 1938 to 1956 were built to standard designs, and their roofs, underlay and spouting are now many decades old. Later homes towards Mt Kaukau and Newlands can carry concrete tile, decramastic or longrun steel, and infill units add low-pitch roofs. A COLORSTEEL re-roof suits most of these homes.

Roof Replacement Johnsonville FAQs
Is it worth re-roofing a 1940s Johnsonville state house or just repairing it?
If the underlay and fixings have failed across the roof, patching tends to buy little time. An inspection from the roof and the roof space shows which applies, and where both are reasonable we quote both.
Can you replace just part of the roof?
Sometimes. If one face has failed and the rest is sound, a partial replacement can work, for example the face that takes the prevailing wind. Joining old and new steel and flashing the join properly matters, and we will say if it is not sensible.
How far ahead should I plan a roof replacement?
Getting quotes a few months ahead gives you time to compare and choose materials. Late spring and summer give the most settled weather, though roofs are replaced all year round, and our written quote states how long the price is held.
