Why Roof Leaks Are More Likely to Happen in Winter

And What Queensland Homeowners Should Watch Out For

In Queensland, most homeowners brace themselves for summer storms, but did you know roof leaks are often more likely to appear in winter? Cooler months bring a different kind of weather challenge, especially for older tiled roofs that have quietly deteriorated over time.

At Storm Call Roofing Projects, we often see a spike in leak-related enquiries during the winter season. Here’s why that happens and how you can stay ahead of it.

Why Winter Exposes Roof Weaknesses

Even though Queensland winters are milder than other parts of Australia, they still present a perfect storm of conditions that can reveal hidden roof problems.

1. Cold Mornings and Dew

Heavy morning dew can settle into small cracks or gaps between tiles, especially on south-facing slopes that stay shaded longer. This consistent moisture can seep under the tiles, affecting underlayment and eventually causing leaks.

2. Wind-Driven Rain

Winter fronts often bring strong, gusty winds along with rain. If roof tiles or ridge capping are loose or damaged, wind-driven rain can easily force its way underneath.

3. Lack of Sunlight

In cooler months, tiled roofs dry more slowly after rain or morning dew. Prolonged moisture exposure can highlight issues like porous or hairline-cracked tiles that wouldn’t be obvious during drier, sunnier periods.

4. Blocked Gutters and Valleys

Falling leaves and debris often collect in winter, especially from deciduous trees. Blocked gutters and valleys can cause water to back up and overflow into roof spaces, leading to interior ceiling stains or water damage.

Common Winter Leak Hotspots on Tiled Roofs

Some areas are more prone to letting in water, especially during winter conditions:

  • Cracked or displaced tiles
  • Broken or deteriorating ridge capping
  • Roof valleys filled with debris
  • Skylight and vent flashings
  • Chimney surrounds and roof penetrations
  • Old mortar bedding that has crumbled or washed away

Warning Signs to Watch For

Catching a leak early is key. Look out for:

  • Damp spots on ceilings or cornices
  • Dripping sounds after rain
  • Mould or mildew in corners of rooms
  • Water stains near light fittings
  • Musty smells in the roof cavity

If you notice any of these signs, even if minor,  it’s time to have your roof inspected.

Preventing Winter Roof Leaks

Being proactive is always better than reacting to interior damage. Here’s how to minimise your risk:

  • Schedule a roof inspection before winter to catch loose tiles or weakened ridge caps.
  • Clear gutters and roof valleys of leaves and debris.
  • Check internal ceilings and roof cavity for early signs of moisture.
  • Trim overhanging branches to reduce leaf build-up and improve sunlight exposure on roof surfaces.
