What Starts as a Stain Could Cost You Thousands: Why Roof Leaks Are Sydney’s Silent Killer
Water damage is one of the most common — and most costly — building issues in Australia. And more often than not, it starts with something that looks harmless: a ceiling stain, a swollen cornice, or a bit of peeling paint after rain.
But what you see on the surface is rarely the full story.
At Projex Pro, we’ve been called to sites where a minor drip turned out to be a major defect. Water that enters through a cracked tile or blocked gutter can travel down internal walls, soak into insulation, corrode fixings, and even compromise your home’s fire safety or structural integrity.
In fact, over 40% of building complaints in NSW strata schemes are linked to water-related defects, according to Fair Trading and Deakin University. And for private homes? Roof and gutter failures consistently rank among the top three causes of insurance claims nationwide.
What Causes Most Roof Leaks?
Blocked or overflowing gutters
Cracked or missing tiles
Lifting or deteriorated flashing around skylights, chimneys, or vents
Poor maintenance of tree overhang and leaf build-up
Wind-driven rain entering vulnerable roof junctions
The scary part? Most of these issues aren’t visible from the ground.
What You Can Do Now to Stay Ahead
Walk your home after a heavy rain. Look for drips, stains, or swelling in ceilings or corners.
Clean your gutters every 3–6 months — more often if you’re surrounded by trees.
Book a professional roof inspection if you’ve had recent storms, visible staining, or your roof is over 10 years old.
Most serious leaks can be prevented with regular maintenance. And if you do spot something, acting quickly can save you thousands.
