As winter begins, it’s time to think about the impact that Perth’s unique weather patterns could have on your home. Prevailing winds paired with heavy rains can cause significant water intrusion and damage. We encourage you to take steps to protect your home.

Common Winds in Perth

The Fremantle Doctor:  This well-known sea breeze typically occurs in the afternoon, bringing cooler air from the southwest. While refreshing, this breeze can also carry moisture from the ocean, which can seep into cracks and openings in your home, leading to water damage over time.

Easterlies: These winds blow from the east, often carrying hot, dry air during the summer months. However, during periods of high humidity or rain, these winds can push moisture into your home from the opposite direction, catching homeowners off guard.

Westerlies: Often associated with storm systems, these winds can be particularly strong and bring significant rainfall. Homes that are not adequately sealed or have structural vulnerabilities can suffer from water intrusion during these periods.

Rain driven by strong winds can penetrate your home through various openings, leading to water intrusion. This can occur through:

Partial Vacuum: A partial vacuum can occur when strong winds draw air out from one end of the roof, creating a suction effect. This suction can cause water to be pulled into the roof space through any small openings or gaps, leading to water ingress.

Cracks and Gaps: Even small cracks in the slab, brickwork, or around windows and doors can allow water to seep in. It’s essential to seal these gaps to prevent water ingress.

Roofing: Missing or damaged tiles, deteriorated flashings, and blocked gutters can lead to water entering the roof space or ceiling cavities. Regular roof maintenance is crucial to prevent leaks.

Cladding: Poorly sealed or damaged cladding can allow water to penetrate the exterior walls. Ensuring that your cladding is properly installed and maintained can help protect against water damage.
