Understanding Deck Leak Issues

Decks are wonderful additions to homes, offering outdoor space for relaxation and entertainment. However, they can also become sources of significant headaches when they start to leak. Deck leaks can cause severe damage to a home’s structure, leading to costly repairs. In this blog, we’ll explore the common causes of deck leaks, effective prevention strategies, and how Sound Homes, weathertightness specialists in Auckland, can help ensure your deck remains leak-free and your home protected.

The Importance of Deck Weathertightness

According to BRANZ (Building Research Association of New Zealand), recent news reports highlight that decks and balconies are critical areas of concern regarding a building’s weathertightness. They can impact the durability of construction components and, over time, their structural integrity. The E2/AS1 risk matrix (weathertightness risk) classifies two types of decks:

  1. Enclosed (Waterproof) Decks: These have an impermeable upper surface and are closed on the underside, often with habitable space below. They are likely to incorporate a solid framed balustrade.
  2. Open Timber-Slatted Decks: These are usually constructed with an open barrier.

Leaky building statistics have revealed that waterproof decks are a significant cause of problems. Nationally, approximately 14% of new buildings consented have waterproof decks, but in around 67% of cases reported to the Weathertight Homes Resolution Service, the leak was attributed to the deck and/or balustrade walls—a disproportionately high rate. All decks pose some risk where they are attached or incorporated into the building’s weatherskin. (Source: Trevor Pringle, BRANZ)

Common Causes of Deck Leaks

Deck leaks can stem from a variety of issues, including:

  1. Poor Construction: Inadequate or incorrect construction techniques are primary culprits. This includes improper sealing, lack of flashing, and incorrect slope.
  2. Aging Materials: Over time, the materials used in deck construction can deteriorate, leading to cracks and gaps through which water can penetrate.
  3. Inadequate Waterproofing: Insufficient waterproofing measures, such as failing to apply sealants properly or using subpar waterproofing materials, can leave a deck vulnerable to leaks.
  4. Drainage Issues: Poor drainage systems that allow water to pool on the deck surface can contribute to leaks. Water should always flow away from the deck, not towards the house.
  5. Climate Factors: Exposure to harsh weather conditions, such as heavy rainfall, can exacerbate existing vulnerabilities and lead to leaks.

Prevention Strategies

Preventing deck leaks involves a combination of good design, quality materials, and regular maintenance:

  1. Proper Design and Construction: Ensuring that the deck is designed with an adequate slope to facilitate water runoff and that proper flashing is installed to direct water away from vulnerable areas.
  2. High-Quality Waterproofing: Using top-grade waterproofing materials and techniques during construction. This includes applying durable sealants and coatings.
  3. Regular Maintenance: Conducting regular inspections and maintenance to address small issues before they become major problems. This includes reapplying sealants and checking for signs of wear and tear.
  4. Effective Drainage Systems: Installing and maintaining efficient drainage systems to ensure water does not accumulate on the deck surface.
  5. Professional Inspections: Having your deck inspected by professionals periodically to catch potential issues early.
