Roof Plumbing Repairs and Why It Is Crucial Before the Sydney Rainy Season

19 December, 2024

Sydney is one of Australia's rainiest state capitals, with an estimated annual rainfall of 1044 mm. Of that, there are two distinct "seasons" of rainfall, a relatively dry period between July and December, and a much wetter January to June, with the highest monthly rainfalls occurring in February and April as the heat of summer begins to cool into the milder temperatures of autumn.

This weather pattern can bring incredible deluges, with 111 mm recorded in just 24 hours in April 2024 at Observatory Hill in the city's CBD. With such powerful wet weather systems increasing, the impact on Sydney's roofs has never been more intense. This makes the time leading up to the holidays and the new year the perfect opportunity to assess the condition of your roof and plumbing to make sure that wild weather stays where it belongs—outside.

Common Roof Plumbing Issues in Sydney

Heavy rain, particularly from storms with high winds, has a way of finding any gaps in the shingles or roof tiles that milder rain events might not reveal. Most of us probably don't make a habit of going up onto the roof very often, so we're likely unaware of issues until the storm reveals them. However, by the time we do notice drips coming from the ceiling, that means rainwater has already invaded the ceiling space, causing wet insulation and electrical wiring.

There's no one reason why water finds its way inside the roof, but the most common roof plumbing problems exacerbated by heavy rain include:

  • Leaks and poor drainage: Over time, roof sarking (waterproof sheets laid beneath roof tiles) can fray or come unstuck. Water can also begin to pool in places where the angle of run-off is interrupted, forcing the water to find another way to escape.
  • Broken or blocked gutters and downpipes: A blockage of debris, such as sticks and leaves, can interrupt drainage and cause water to overflow, resulting in localised flooding that can leak into the house.
  • Cracked or missing tiles: Roof tiles are a house's primary defence against the elements, and if one has become dislodged or broken in some way, it creates a gap in this defence that rainwater is sure to find.
  • Flashing issues around chimneys or skylights: Flashing is the protective layer or frame around a chimney or skylight, which provides a waterproof seal between the feature and the roof's weather-resistant integrity. Over time, the weather can create cracks or force leaks in this flashing.

The Risks of Neglecting Roof Repairs

The consequences of ignoring roof plumbing issues include inviting moisture into your living space, which can create a wide range of costly problems down the line. Water can damage your home's interior and compromise its structure, causing rippling in the plasterboard, flaking paint, and weakened joins. Over time, this can sharply reduce property values as potential buyers will see the cost involved in renovation and repair.

More than that, once inside the ceiling space or walls, the rain and moisture has a difficult time escaping again with little or no ventilation, creating a haven for mould growth, which comes with health risks, such as severe respiratory illness. Additional health issues arise from moisture coming into contact with your home's electrical circuits, causing corrosion and damage, and the risk of electrical shock when using appliances or taps.

How to Tell If Your Roof Needs Repairs

While the presence of water dripping from your ceiling during a thunderstorm is the most obvious sign of roof issues, there are several more subtle signs that homeowners should look out for regularly, not just during periods of wet weather:

  • Make regular rounds around your home, paying attention to those least-frequented rooms, to check for moisture beading on the walls or water stains on the ceilings.
  • Take a walk around the perimeter of your house and inspect your gutters for signs of visible damage or debris. If you're able, use a ladder to inspect more closely any issues you spot from the ground.
  • Check your attic or ceiling space for signs of dampness or mould. You should be able to feel and smell if the air is substantially more humid or damp, while a visual inspection by torchlight should reveal the presence of any mould.

If you notice any of these signs in or around your property, it is best to organise a professional inspection with a qualified plumber, who can then diagnose the source of the leak and provide solutions to reduce and repair water damage.

Roof Plumbing Repairs vs. Replacement

Whether you need repairs or replacement depends on how severe the damage to your roof is and how long it has been allowed to accrue. Roofing materials are sturdy and can handle wear from Australia's harshest elements, but their longevity comes with a need for intervention and frequent inspections.

Roofing repairs include realigning tiles, using epoxy to seal minor cracks or holes, or removing clogs and debris from downspouts and drains.

Replacements, on the other hand, involve removing tiles to replace sarking, installing new skylight flashing, and the installation of new sections of damaged guttering or piping, broken tiles, or laying down new layers of weatherproofing materials.

Benefits of Roof Plumbing Repairs Before the Rainy Season

Prevention and preparation for storm season increase the longevity of your room and the home sitting dry and comfortable beneath it. Taking advantage of the lower rainfall in Sydney from July to December means that repairs and replacements have a longer time to settle and sealant can dry more effectively in less humid air.

Being proactive about repairs helps you to avoid costly damage, both to the roof and inside the home when it is exposed to water. Maintenance also increases the roof's lifespan, by repairing or replacing minor parts before the damage has a chance to spread to require a full replacement.

Finally, you can enjoy Sydney's storm season without fear, enjoying peace of mind even during periods of heavy rain.

How to Choose a Roof Plumbing Service in Sydney

If you've conducted your own checks and found evidence of damage or moisture in or around your roof, it's now time to find a reputable and trusted plumber to help you solve the problem. But how do you know which plumber is best for you?

First, search for local Sydney plumbers, specifically those local to your area as they will have the local expertise of both local council regulations and compliance, as well as the specific drainage systems, roof styles, and common problems found in your area. Next, check their website for evidence of licences and insurance, while a quick online search can bring up a wealth of reviews from previous customers that you can peruse.

Another important note is to check the warranties offered on plumbing work to ensure any repairs that aren't up to the test will be fixed at no extra charge.
