Weathertightness Worth It?

We all know the saying, Auckland has four seasons in one day. One second it will be blue sky’s out and the next minute you are fighting hail as you walk back to your car. So when it comes to building a new home, its important to get the weathertightness right, helping you protect your home against the unpredictable weather Auckland has to offer.

Weather tightness can be broken down into the 4 D’s – Deflection, Drainage, Drying and Durability. Let’s look at what they are and how they can help protect your home.


The best way to protect your home from the Auckland elements is by deflection. Deflecting the harsh winter rain with quality cladding and joinery will stop the weather getting into your home. Looking at designs with eves on the roof and is also another feature that can be used in the deflection element of weathertightness. Deflection elements are designed to take the hit of the elements and direct rainwater away from structural elements of your home. It might be a simple design choice during the early stages of your build that can have the greatest effect on your homes weathertightness.


When the winter rain targets your new home, where will it go? Any new build should have a suitable drainage system in place to help take the water away from your home. Whether your drainage system is designed to be invisible to the eye or becomes a part of the home design itself, your drainage system should be able to protect your new home in any weather situation. Don’t worry, our project managers and architects will work with you to ensure your home has the best drainage system in place ready for your when you move in.


Referring to the ventilation in your home, having systems in place to help keep your home dry is essential for any new build. By taking air from the roof space and filtering and pumping it into the main living areas via ducting and vents or self-contained ceiling vents that have their own built-in fans, home ventilation systems help draw excess moisture out of the air and preventing mould and condensation from damaging your house.


We have discussed deflection, drainage and drying and how they all impact your homes weather tightness, but what about durability? Durability refers to the durability of the materials you used to construct your home. Using high quality, durable materials throughout the build might be the more expensive option to start with, however investing in a little now will save you a lot in weathertightness in the long run.
