Weatherproofing Houses in New Zealand

New Zealand has a wet and windy climate particularly in certain locations, all the houses in those locations need to be built to be able to sustain bad weather. A number of specialist tradespeople are required in the process when building a new house or weatherproofing an existing house.

The builder is the obvious first tradesperson, as they need to build the house so that it can sustain high winds and driving rain. The most important requirement is that the house does not change shape in anyway during high winds, is this can open up small cracks in the cladding or the roofing that will let in cold air and moisture. The house must therefore be built as a rigid structure, aided must be firmly attached to it’s foundations it also must be built rigidly underground so that the house does not shift relative to the ground during an earthquake.

The regulations for building Framework and roof trusses and for attaching the frames to the foundations pretty much make certain that the house will not move or twist during high once. Almost all New Zealand Residential Housing using timber framing, and in previous decades the builders wood construct diagonal nogs in which wall to make sure that the wall cannot trust. In modern times diagonal bracing is simply a thin metallic strap that is attached between the floor and ceiling at opposite corners of each war.

Once the solid and rigid frame has been built then the Builder also needs to install cladding. Whether the cladding is brick or timber or some other product, it is absolutely vital that the cladding is firmly attached to the wall and cannot move during high winds. The cladding also needs to be isolated from the wall with waterproof paper so that anymore moisture that does get in behind the cladding can not get into the wooden framing. The choice of type of is very important in New Zealand’s climate, and the most popular cleaning by a long way is the trusted weatherboard which is relatively low cost and which reliably prevent moisture Ingress.

The roof and Gables and eaves also obviously vital to make a house weatherproof, and the choice of roofing material is very important here as well. The most popular roofing material in New Zealand is corrugated Steel, nowadays with a pre bonded colour, with tiles being a popular second choice. The early steel roofs had the problem of rust and leakage and movement of the lead head nails, and they require periodic maintenance and painting. However early tile roots also attract Moss and lichen, plus the tiles can move during high winds and the tiles are relatively fragile, so can break during high winds. A vital aspect for any roof is the flashings at the roof Peaks, corners, changes with angle, and around rooftop structures such as chimneys and skylights. It is the roofer’s or plumbers job to make sure the flashing is installed securely and will remain waterproof with a tight seal during the highest winds. The Builder also has to make absolutely certain yep the house is sealed around the gatherings in under the eaves.

What’s the roof and the cleaning has been securely installed then it is the painters job to make sure that the roof and cladding is painted in a professional manner that means it will be a good weatherproof seal for the next decade at least.
