Weathertightness to Protect Your Home, Health and Wallet

When it comes to owning a home, ensuring that it is weather-tight is as important as locking your doors at night. Weather tightness, the ability of a home to resist harsh weather like wind, rain, and other environmental elements, is not just a feature – it is a necessity.

The main reason for maintaining a weather-tight home is to protect its structural integrity. Water is a notorious enemy of many construction materials, especially wood, which is commonly used in framing and detailing. When water penetrates gaps in a home’s envelope – whether that be through the roof, walls, or windows—it can cause the wood to rot, metals to corrode, and mould to form. These issues can weaken the structure of your home, potentially leading to costly repairs and even fatal deterioration if left unaddressed.

Mould and mildew growth is a common result of moisture entering your home, and it presents more than just an aesthetic problem. Mould spores can lower air quality and pose health risks, especially to those with allergies or respiratory conditions. Ensuring your home is weather-tight keeps the indoor environment dry and free from harmful organisms, enabling healthier living conditions.

A weather-tight home is also an energy-efficient home. Gaps and leaks in a home’s exterior can lead to air infiltration, which makes heating and cooling systems work harder to maintain comfortable temperatures. This not only leads to higher bills but also increases your home’s carbon footprint. By making sure your home is sealed against the elements, you can keep your energy consumption lower and your home more comfortable throughout the year.

From a financial perspective, a weather-tight home is a valuable home. Potential buyers assess the condition of a home’s exterior and its resistance to weather-related damage when making a purchase. A well-maintained and weather-tight home is more appealing and can command a higher market price. Regular checks and maintenance can be a smart investment that pays dividends in terms of property value.

Checking your home’s weather tightness involves having a look at several key areas:

• Roof and Shingles: Look for missing, damaged, or aging shingles that may allow water ingress
  
• Windows and Doors: Check for gaps or failing seals around windows and doors where air and water could potentially enter
  
• Walls: Examine the exterior walls for any signs of damage or wear, such as cracks or missing pieces in the siding
  
• Foundation and Basements: Ensure there are no cracks or leaks in the foundation or basement areas that could let in moisture

The importance of checking if your home is weather-tight can’t be overstated. It is vital for maintaining the safety, efficiency, comfort, and value of your property. Homeowners should prioritise regular inspections and maintenance to address any potential issues before they become serious issues. By doing so, you protect your investment and ensure your home remains a safe shelter against the unpredictability of New Zealand weather.
