How to prepare your roof and gutters for summer in Sydney

After a pretty wet and woolly winter, many homes across Sydney’s North Shore are showing signs of wear. The combination of consistent rainfall, mature trees shedding leaves, and ageing roofing materials puts local properties at higher risk of water damage, especially as we head into summer.

Although Sydney doesn’t have a defined “storm season”, data shows that heavy rain, flash flooding and high winds are most common from October through March. And for homes with older roofs or blocked gutters, these seasonal events can quickly turn into costly repair jobs.

As a trusted roof plumber in North Shore, STS Plumbing has helped hundreds of local homeowners prepare for the summer months with reliable roof and gutter inspections, targeted repairs, and expert advice.

Here’s everything you need to know to safeguard your home.

Why Sydney roofs need more attention than you think

Roofs in Sydney, particularly on the leafy Lower North Shore, face a perfect storm of environmental stressors:

Tree debris from gums, jacarandas and plane trees clogs gutters and corrodes flashing
UV exposure and changing temperatures wear down tiles, seals and membranes
High winds can dislodge tiles and break down ridge capping
Persistent moisture leads to mould, rot and sagging roof structures

And because many roofing issues develop slowly and silently, they’re often discovered only when it’s too late, like during a major rain event.

At STS Plumbing, we believe prevention is always cheaper than cure. That’s why we offer comprehensive roof and gutter inspections in Lane Cove and surrounding suburbs, helping local homeowners avoid unexpected damage and expense.

The risks of ignoring minor roof and gutter problems

Small issues can turn into big ones quickly, especially during periods of heavy rain or storms. Here’s what can happen if you delay:

Internal leaks leading to ceiling stains, bubbling paint and water-damaged insulation
Overflowing gutters flooding garden beds, walkways or foundations
Mould growth in roof cavities or wall voids
Structural damage from prolonged exposure to moisture
Pest infestations, with rodents and insects attracted to damp timber

Our licensed roof plumbers on the North Shore are trained to identify the early signs of these problems and recommend proactive repairs to protect your home and save you money.

How to prepare your roof and gutters for summer

If you’re unsure where to start, here’s our proven checklist for getting your roof and gutters summer-ready.

1. Clean out your gutters and downpipes

The number one cause of water ingress we see is blocked gutters. Leaves, sticks and silt accumulate quickly, especially in tree-lined suburbs like Mosman, Willoughby and Artarmon. If water can’t flow properly through your gutter system, it will find its way into places it shouldn’t.

Tip: Consider installing quality leaf guards, particularly if you’re surrounded by tall trees.

2. Inspect for cracked or slipped tiles

Even a single broken tile can allow water to seep into your roof cavity. Look for signs of shifting or cracking, especially along roof ridges and valleys. Don’t attempt to walk on your roof, this is best left to a qualified roof plumber.

3. Check for rusted flashing and loose fittings

Metal flashing around chimneys, skylights and vents is designed to keep water out. But if it’s rusted, cracked or lifting, it’s a likely entry point for moisture.

4. Clear roof valleys

Valleys are designed to channel water efficiently, but when they’re full of debris, they can redirect water under your tiles. Regular clearing is essential to maintain proper flow.

5. Examine gutter alignment

Gutters should have a consistent fall toward the downpipes. Sagging or back-falling gutters trap water and increase the risk of corrosion and overflow.

6. Look for signs of internal damage

Check inside your roof cavity (if safely accessible) for signs of moisture: dark patches, mould, or musty smells. Watermarks on ceilings or peeling paint indoors are also red flags.

7. Book a professional roof inspection

Many problems can’t be seen from ground level. Booking an annual roof and gutter inspection with a licensed roof plumber in Lane Cove or your local suburb ensures hidden issues are uncovered and resolved.
