WHAT DOES WEATHER TIGHTNESS MEAN IN AUCKLAND? Weathertightness refers to the resistance against the elements, keeping a building completely waterproof and undamaged from wet weather.
In New Zealand, particularly, weathertightness (otherwise known as “leaky building syndrome”) is a massive issue due to the previous widespread popularity of Mediterranean style builds that were not very well built and suffered major water damage, which is very costly to fix if left undiagnosed. Leaky buildings cannot fix themselves!
