Re Roofing Older Houses in New Zealand

New Zealand has a very large stock of older houses that were built before the 1950’s and earlier. These houses are almost all timber framed on wooden piles, and unless they have been meticulously maintained then they will require periodic renewal.

This renewal will generally involves repiling the house at least once that’s life, repainting the house at least every 10 to 15 years, and re roofing the house every 20 to 30 years. Re roofing an old house is not that expensive in the scheme of things, but it can make a huge difference to how weather proof and storm proof the house is and to how attractive it looks. In general the new roof will be long run colour Steel, and this is both strong and very long life is the colour is coated on the steel during manufacturer and will not fade or deteriorate over a number of decades.

Many older houses have earthenware tile roofs which were stylish back in the day but are now a source of leaks and ongoing maintenance as individual tiles deteriorate. Tiles can also accumulate Moss and lichen, which weakens the tiles causing them to break or crack and two leak and be vulnerable during very strong storms.

The only problem for the roofing company who is replacing and earthenware tile roof is that they must dispose of the old tiles, and this can amount to a tonne or more of broken tiles. Removing the tiles from the roof and the building site his basically hard physical labour. However once the tiles have been removed from the site then putting up the new roof is a much easier proposition. The existing roof frames are generally made from original very strong native timber and were built to support a very heavy load, and in most cases for the roofer there is no repair work required to the frame.

The new roof is mounted on top of sheets of roofing paper, and is attached using self tapping roof screws. This attachment method virtually never results in damage to the roof, and is very easy for the roofer with a modern battery powered screwdriver. The attachment process is fast, efficient and safe, and the final result is a roofing Hamilton that is very firmly attached to what is generally a very strong existing timber frame. Modern steel roofs also have very good flashing options for the corners and bends, and the end result is always a very tidy job that is extremely waterproof and resistance to the wildest storms.
