Signs of a leaking roof

What can cause a roof leak?

There are several factors that can contribute to a leaking roof; it pays to familiarise yourself so you know when to give us a call.

Damaged Roof Tiles

Extreme weather is one of the most common causes of sudden tile damage. High winds, heavy rains, and falling debris can bruise or dislodge shingles, create movement in your roof tiles and even crack them. Roof tiles are designed and aligned in a specific way so that water runs off them; even a small gap in the roofing can cause water to leak through.

Rusted Flashings

Roof flashings are thin metal strips that cover the joinings in your roof. Over time, they can rust, crack, or corrode, letting water seep into vulnerable areas. 

Blocked Gutters

When gutters fill with leaves and debris, water falling on the roof has nowhere to go or drain. Water can back up and overflow, eventually finding its way under the roofing materials. It may also run down walls, soak footings, and undermine your home's foundations. 

Roof Valleys

Roof valleys, where two slopes meet, provide the means for water to travel off metal roofs. Leaks commonly occur here if the metal liner has perished over time from UV or rain exposure. 

Skylight Issues

The seals around skylights often perish over time, leading to leaks. Once the flashing has rusted, water can run down the skylight shaft into your interior walls.

A word of advice from our roof plumbing experts:

"The key to preventing roof leaks is regular inspection and maintenance. By catching small issues early, you can avoid larger, more costly problems down the line."

By keeping an eye on these potential problem areas and addressing any issues promptly with a roof plumber, you can extend the life of your roof and maintain the integrity of your home. Whether you're dealing with damaged shingles or clogged gutters, understanding what causes roof leaks is the first step in keeping your home dry and protected.

How does weather impact roof integrity?

We all know that Melbourne’s weather is wildly unpredictable; one minute it’ll be beautifully sunny and the next it’ll be torrentially raining. Extreme weather conditions can take a significant toll on your roof's structure and materials. For instance, heavy rain and hailstorms can cause immediate damage by cracking roof tiles and denting roof surfaces. Over time, UV rays from the sun can also degrade roofing materials, causing them to break down and become less effective at repelling water. 

Even wind can be a culprit. High winds can lift or remove roof tiles, especially if they are already compromised or improperly installed. Gusts may also dislodge roof flashing, gutters, and other critical components, creating vulnerabilities that allow water infiltration. 

Considering these risks, it's advisable to conduct a visual check of your roof following severe weather events and perform regular inspections throughout the year. You want to keep your roof well maintained year-round, as each season brings different challenges. Professional roof inspections can help catch early signs of damage, ensuring timely repairs and prolonging the life of your roof.

Note: Water stains can appear far from the actual leak

Don’t be fooled by the damp patch on your ceiling. Because water runs along rafters and joists before it drops, there can be metres between the water stain and the roof leak. The only way to be 100% sure is to get up on the roof and assess it.  A professional roof plumber will identify whether it’s because your gutters are overflowing or there’s a crack in your roofing . We recommend having an expert do this, especially after a storm when it’s slippery and the risk is higher. A professional roof plumber will know what to look out for and will provide a targeted fix.

Regular maintenance of your roof is recommended

Look out for signs of damage such as small holes, rust, corrosion, missing pieces, or any bends, cracks, and dents on the flashing. If you're unsure, getting a professional roof inspection a couple of times a year can be invaluable. This proactive approach helps ensure the longevity of your roof and prevents small issues from turning into major repairs. 

Consider getting a professional roof inspection at least once a year. A skilled inspector can identify potential problem areas and recommend timely fixes, ensuring your roof remains in excellent condition and leak-free.
