Weathertightness
Pre-purchase Weathertightness Inspections, by a Experienced Weathertightness Building Inspector.
Our years of Pre-purchase building inspections and Weathertightness training, combined with our specialist building inspection tools ensures you achieve peace of mind for your building purchase.
Weathertightness Inspection report.
The report includes the details of our findings and provides interior percentage readings for each room; including around all wet room fittings. Plus suspected causes, photos of defects found and repair recommendations .
The exterior assessment covers the roof, gutters, penetrations, joinery, cladding, flashings, ground clearance, and decks.etc. In which we highlight any potential shortcoming sighted.
No matter which cladding you have there is potential for water ingress, as in the testimonial by Evan:
“You picking up those issues that the other building inspection missed, really meant I dodged a bullet. For the sake of $…. your work has saved me at least $50,000, a great payback ratio in anyone’s books”
Weathertightness Ingress Issues.
Weathertightness is a term that describes how resistant a building is to the weather.
In Auckland buildings are exposed to significant rainfall, which is often excessively heavy; making it difficult for roofs and gutters to cope. Often almost horizontal wind pressures threaten the smallest opening and high UV rays tests the limits of many exterior building products. Therefore it is understandable that the building’s exterior envelope (particularly the roof, cladding junctions, and waterproof decks) require a high level of weathertightness, to provide the durability we expect. Rainwater needs to be deflected, drained, or dried off exterior surfaces and prevented from penetrating the building. As water drains down wall surfaces or across roofs and decks, it passes over joints, junctions, intersections, around joinery, and other cladding penetrations that need to be watertight and well maintained.
Many factors have contributed to problems with weathertightness in our buildings especially since the mid-1990s, with poor design, project management, inferior products, building practices and lack of maintenance all contributing to a high level of failure. Leading to structural damage, great expense, anguish, and health problems.
A high percentage of homes inspected have moisture issues, interior, exterior or both.

Plaster Homes
As part of the leading process, most banks request Weathertight Inspections, especially on Monolithic ( plaster homes). Being a bank preferred inspection company, North Star Inspections, offer a Weathertightness Inspection with or without Infrared.
The addition of the infrared camera expands our ability to locate moisture and ingress points; assisting the inspector in the detection process. It is important to note has thermal imaging has limitations and should only be used in conjunction with other moisture meters.
The inspector will not only work to try and locate accessible moisture but attempt to narrow down the likely failure mechanism and advise what could be done to help prevent any further ingression and what other steps need to be taken.
These images highlight some of the defects you need to know about.
Leaks
Do you have a leak that only comes in when it rains, or when the wind blows from one direction?
Possibly it’s a leak which has not happened before or a leak you just can’t locate.
Call North Star Inspections – this is our speciality.
Invasive Weathertightness & Moisture Ingress Investigation Surveys
For leaking homes or commercial properties with ingress issues. 
This survey will involve both invasive and non-invasive Inspection tools, including Infrared, in order to identify the extent of the ingress issues and damage caused.
The ingression locations, causation, and exterior weathertightness shortcomings are noted in a report for further investigation, upon which a scope of works can be prepared, for a repairer. More in-depth invasive investigations and timber sampling may be required in some areas .
