Terracotta tiles are a classic roofing choice across Brisbane—durable, attractive, and ideal for handling Australia’s hot climate. But like any part of your home, they need maintenance to stay in good shape. One of the most common areas that deteriorate over time is the mortar under and around your ridge capping. If left unchecked, this can lead to serious issues.
So, how can you tell when your terracotta roof needs attention? Let’s explore the key signs that indicate it’s time for repointing or re-bedding.
What’s the Difference Between Repointing and Re-bedding?
• Re-bedding involves removing the old mortar beneath the ridge caps and laying fresh mortar to create a stable base.
• Repointing is the process of applying a new layer of mortar over the bedding to seal any gaps and reinforce weather protection.
If your roof’s bedding is still solid, repointing alone may be enough. However, when bedding becomes loose or starts to disintegrate, both processes are typically needed.
1. Cracked or Missing Mortar on the Ridges
Take a walk around your home and inspect the ridge lines. If you spot missing mortar, visible cracks, or debris in the gutters, your roof likely needs work. Gaps in the mortar can let water in and loosen the tiles, making the roof more vulnerable to damage.
2. Loose Ridge Capping
Ridge capping plays a key role in securing the tiles at the roof’s peak. If the capping shifts or feels unstable, the bedding underneath has likely broken down. This makes your roof more susceptible to wind uplift during Brisbane’s intense storm seasons.
3. Leaks or Damp Patches After Rain
Noticing water stains or damp spots in your ceiling after rainfall? Even minor leaks could signal a breakdown in the mortar. Moisture can easily find its way through cracked bedding and compromise your insulation and roof structure over time.
4. Uneven Rooflines or Misaligned Tiles
Your tiled roof should have clean, even lines. If tiles look out of place or the roofline appears to sag, it’s often due to worn or loose bedding. While the change might be gradual, it tends to accelerate if not addressed early.
5. Moss or Plants Growing in the Gaps
Any vegetation on your roof—moss, grass, or weeds—is a red flag. This indicates moisture is being trapped, usually because of deteriorating mortar. Beyond being unsightly, it can significantly shorten your roof’s lifespan.
Don’t Wait Until the Damage Worsens
Small cracks in mortar may seem harmless at first, but they can lead to major problems if ignored. Early maintenance not only saves you money in the long run but also extends the life of your roof and prevents the need for more extensive repairs.
