Defending Against Roof Leaks

At Sound Homes, we understand the importance of a sturdy roof. It’s not just about providing shelter; it’s about safeguarding homes from the elements. Roof leaks can wreak havoc on property, leading to costly repairs and potential health hazards from mold and mildew. That’s why we’re here to shed light on the causes of roof leaks, offer effective remedies, and demonstrate how Sound Homes can be your trusted partner in ensuring a weathertight roof.

Common Causes of Roof Leaks

According to BRANZ (Building Research Association of New Zealand), roof leaks can stem from various sources, each requiring attention to prevent further damage:

  1. Cracked, Missing, or Dislodged Tiles or Shingles: Over time, wear and tear can cause roofing materials to crack, break, or become dislodged, creating openings for water infiltration.
  2. Roofing Sheets Without Turn-Ups: Inadequate roofing design, such as sheets without turn-ups at the top end, can allow water to seep underneath, leading to leaks.
  3. Missing Nail Heads or Waterproofing Washers: Improper installation or deterioration of fasteners like nail heads or waterproofing washers can compromise the integrity of the roof, allowing water ingress.
  4. Lifted, Corroded, or Damaged Flashing: Flashing serves as a barrier against water intrusion around roof protrusions and joints. When flashing becomes lifted, corroded, or damaged, it loses its effectiveness, leading to leaks.
  5. Corroded, Damaged, or Blocked Valley or Internal Gutters: Valleys and internal gutters are critical drainage pathways on roofs. Any corrosion, damage, or blockage in these areas can impede proper water flow, resulting in leaks.

Effective Remedies for Roof Leaks

Addressing roof leaks promptly is crucial to prevent further damage to your property. Here are some effective remedies:

  1. Roof Inspection and Maintenance: Regular inspections by professionals can catch potential issues before they escalate. Sound Homes offers comprehensive roof inspection services to identify vulnerabilities and provide proactive maintenance solutions.
  2. Tile or Shingle Replacement: Repairing or replacing cracked, missing, or dislodged tiles or shingles can restore the weathertightness of your roof and prevent water infiltration.
  3. Proper Flashing Installation or Replacement: Sound Homes specializes in expert flashing installation or replacement, ensuring that vulnerable areas of your roof are adequately protected against leaks.
  4. Gutter Cleaning and Maintenance: Clearing debris and ensuring proper drainage in valleys and internal gutters can prevent blockages and water buildup, mitigating the risk of leaks.
  5. Sealing and Waterproofing: Applying appropriate sealants and waterproofing solutions to vulnerable areas can enhance the resilience of your roof against water penetration.

Your Home May Benefit from Membrane Roofing

Membrane roofing presents an excellent choice for various roof types, including flat roofs, low-slope, or pitched roofs, and can even extend to decking and below-ground tanking applications. It serves as a reliable solution to maintain optimal warmth and dryness within your home. 

Breathable membranes are positioned within roof structures to thwart water infiltration while permitting moisture to dissipate due to their vapor-permeable nature. This quality facilitates ventilation, enabling buildings to effectively breathe and maintain optimal indoor conditions.

Most Common Types of Membrane Roofing:

1. TPO Waterproofing Membrane: A TPO (thermoplastic polyolefin) is a favoured thermoplastic roofing membrane for its energy efficiency and straightforward installation process. TPO roofs are fused together at seams using heat-welding techniques, resulting in a robust and enduring watertight seal. TPO membranes also boast energy efficiency, as they reflect sunlight and heat, thereby aiding in decreasing the cooling demand for buildings in Auckland.

2. Torch-On – Bituminous Membrane Systems: A dual-layer torch-on roof membrane designed to endure the diverse climatic conditions of New Zealand.

3. PVC Membrane: PVC (Polyvinyl Chloride) roofing is a thermoplastic membrane recognized for its robustness and resilience against water, fire, and chemicals. It is frequently selected for restaurants and other commercial establishments because of its capacity to endure grease and oil.

4.Rubber Membrane: EPDM (Ethylene Propylene Diene Terpolymer) stands as a synthetic rubber single-ply roofing membrane crafted from ethylene and propylene, sourced from oil and natural gas. Renowned for its durability and affordability, EPDM has maintained its popularity for nearly six decades, remaining one of the foremost roof systems utilized today. A significant advantage of EPDM as a roofing membrane material is its fire resistance, surpassing mere resistance to actively impeding the spread of fires.
