What to Check Before the Rain and Wind Set In
Winter has a habit of finding the weak spots in a roof. What looks fine or minor through summer can quickly turn into leaks, water damage and stress once the rain and wind arrive.
The lead-up to winter is the right time to deal with those issues or potential issues, before they start affecting the inside of your home. Your roof protects everything underneath it — ceilings, walls, insulation and structure — and once water gets in, the damage can add up fast.
A simple roof inspection before winter can save a lot of hassle and, in many cases, help you avoid unnecessary and expensive internal repairs when left too late.
Why Winter Is Hard on Roofs
South Australian winters don’t need extreme weather to cause problems. A combination of steady rain, cold nights and strong winds is enough to expose small roofing issues.
- Cold temperatures cause roofing materials to expand and contract
- Rain is heavier and more consistent
- Wind pushes water into areas it normally wouldn’t reach
- Shaded sections of roof stay damp longer, increasing rust and deterioration
Older roofs are especially vulnerable, but even newer roofs can struggle if not installed correctly.
What to Check Before Winter
Look for signs of rust in iron roofing, or lifting, cracks or movement in tiled roofing and tile capping’s.
Old concrete tiled roofing, Asbestos Roofing or Terracotta tiled Roofing are especially susceptible to getting brittle and cracking.
Even minor movement can let water in once rain is driven sideways by wind and often worsen quickly.
Fixings and Flashings
Old screws, perished seals and tired flashing are one of the most common causes of leaks.
Gutters and Downpipes
Leaks in joins often damage timber increasing the scale of repairs required.
Water stains in gutters are solid signs that gutters are not draining correctly.
Cleaning Gutters regularly is also important to protect your home. Blocked gutters overflow quickly in heavy rain, forcing water back into eaves, walls and ceilings causing expensive repairs.
Valleys and Low Points
Valleys are where roof intersects and handle large volumes of water, Valleys are often the first to show signs of rust and where leaks appear.
Roof Age
Roofs over 20–25 years old are more likely to struggle during winter, particularly if they’ve never been restored or upgraded.
Early Warning Signs You Shouldn’t Ignore
Some roof problems aren’t obvious until winter arrives. Keep an eye out for:
- Water stains on ceilings or walls
- Damp or musty smells inside the home after rain
- Rust marks or discolouration on roof sheets or gutters
- Loose or rattling roof sheets during windy weather
- Gutters overflowing even in moderate rain
Roof Replacement vs Roof Restoration
Roof replacement means removing the old roofing and installing a completely new roof.
We use Colorbond steel because it’s designed for Australian conditions and looks great when properly installed. A new roof improves weather protection, drainage and long-term reliability and protection for your most valuable asset.
Colorbond roofing products are backed by a manufacturer warranty from BlueScope Steel for up to 36 years.
Roof replacement is usually recommended when the existing roof has widespread corrosion, ongoing leaks, or is beyond restoration. However, many homeowners also choose a new Colorbond roof for its clean, modern appearance and the confidence that comes with a brand-new roofing system.
A well-installed Colorbond roof can significantly improve both the performance and appearance of a home.
A roof restoration is about extending the life of your existing roof, not replacing it. It’s a great option if your roof is still in reasonable condition and you’d like to improve its appearance while restoring weather protection.
