Why Do New Zealand Buildings Leak?
Leaky buildings have been a significant issue in New Zealand, particularly affecting homes built between the late 1980s and early 2000s. The problem, often referred to as the "leaky homes crisis," is attributed to several factors:
1. Changes in Building Regulations
In the 1990s, New Zealand's building regulations underwent significant changes, promoting more flexible and less prescriptive standards. This deregulation allowed for innovative designs and materials but also led to inadequate oversight and quality control.
2. Use of Inappropriate Materials
Many builders used materials that were not suitable for New Zealand's climate. For instance, monolithic cladding systems were popular but often failed to provide adequate waterproofing, especially when not installed correctly.
3. Design and Construction Flaws
Architectural trends favored complex designs with flat roofs and minimal eaves, which are more prone to water ingress. Additionally, poor workmanship and a lack of understanding of how to waterproof these new designs contributed to the problem.
4. Lack of Skilled Labor
During the building boom, there was a shortage of skilled labor, leading to inexperienced workers undertaking complex construction tasks without the necessary expertise.
5. Climate Impact
New Zealand's climate, characterized by high rainfall and humidity, exacerbates the problem. Buildings not designed to withstand these conditions are more susceptible to leaks and water damage.
6. Inadequate Maintenance
Regular maintenance is crucial for preventing leaks, but many homeowners were unaware of the need for ongoing upkeep, leading to deterioration over time.
Addressing the Issue
Efforts have been made to address the leaky building crisis, including:
- Regulatory Reforms: Stricter building codes and inspection processes have been implemented to ensure better construction practices.
- Remediation Programs: Government and local councils have initiated programs to assist homeowners in repairing leaky homes.
- Increased Awareness: Educating builders and homeowners about proper building techniques and maintenance has become a priority.
The leaky building crisis has been a costly lesson for New Zealand, highlighting the importance of robust building practices and regulations tailored to local environmental conditions.
This is why getting a Pre Purchase inspection report done before you purchase a property is necessary. This ensures that any signs of water ingress or defects are identified and dealt with before purchasing the property.
