Types of Tiled Roof Problems

When you own a home with a tiled roof, there are a few things you should keep an eye on that may cause problems in the future.

Cracks in Tiles

Hailstorms, falling branches, or just old age can leave unsightly cracks in your tiles. These fissures open the door for water infiltration, potentially leading to roof leaks and interior damage.

For minor cracks, specialised sealants can mend the gap. However, large cracks or broken tiles demand immediate replacement. Match the new tile’s colour and type to maintain your roof’s cohesive look.

Dislodged Tiles

Dislodged tiles can compromise how watertight your roof is. This often happens due to improper installation, worn-out sealant, or water damage to the underlying structure.

To fix this issue, your tiles need to be re-fastened with appropriate fixings. If water damage is the culprit, address the underlying issue and have any decayed materials replaced before re-fastening the tiles.

Moss and Mildew Growth

While it may add a touch of fairytale charm, moss growth can wreak havoc on your roof. It retains moisture, accelerates tile erosion, and even attracts insects.

If you find your roof tiles are growing moss or mildew, gently remove with a stiff brush and eco-friendly cleaning solutions. Avoid harsh chemicals, as they can damage the tiles. Regularly clear debris like leaves and branches to prevent moss from thriving in the first place.

Clogged Gutters

Clogged gutters can cause water to back up under your tiles, leading to leaks and interior damage.

You should ensure that your gutters are cleaned regularly, especially after heavy rain or winds. You may want to speak to a roofing specialist about whether installing gutter guards will help to minimise future clogging.

Roof Leaks

A roof leak is any homeowner’s worst nightmare. Identifying the source can be tricky, as water can travel long distances before showing signs of damage.

If you notice water marks on your ceiling, it is time to call a professional roofer to pinpoint the leak. They have the expertise to trace its source and recommend the appropriate repair or replacement.

Tiled Roof Maintenance Tips

When you own a home, maintaining your roof tiles is just another job to add to the list. But because these tiles protect your home, and are constantly in the weather, the maintenance is essential to ensure your home stays safe.

Here are our top tips on maintaining your tiled roof in Brisbane.

Regular Inspections

Aim for at least two inspections per year, ideally in spring and autumn. After severe weather events, like hail storms or strong winds, you should perform an additional check for damage. Check for cracked, chipped, or missing tiles, loose mortar joints, moss or algae growth, and any signs of water infiltration, such as stains or sagging.


Book a roof clean every two to three years, depending on the amount of debris accumulation and environmental factors. This can help to remove moss, algae, lichen, and any accumulated leaves or debris. You should also be sure to clear gutters and downspouts to ensure proper drainage.

Repair and Replacement

Address any cracked, chipped, or missing tiles promptly. Delaying repairs can lead to water damage and further deterioration. You should also secure loose mortar joints to prevent water infiltration and maintain the structural integrity of the roof.

Our other tips for regular maintenance include:

  • Trimming overhanging branches to prevent them from scratching or damaging the tiles.

  • Install gutter guards to minimise debris buildup and make cleaning easier.

  • Invest in professional roof inspections every five to ten years for a thorough assessment and preventive maintenance recommendations.

As with many things, early detection is key to tackling tiled roof problems. Regularly inspect your roof for signs of damage, including missing tiles, cracks, moss growth, and water stains.

Proactive maintenance is your best bet for a long-lasting, trouble-free tiled roof.
