Is Your Roof Cracking? Signs It’s Time to Repoint or Re-bed Terracotta Tiles
Terracotta tile roofs are a popular sight across Brisbane—and it’s easy to see why. They’re tough, stylish, and can last for decades with proper maintenance. But over time, the mortar that holds everything together can deteriorate. Cracked mortar, loose ridge caps, or even small leaks can all signal that your roof may need some professional attention.
Let’s explore the key signs that it’s time for repointing or re-bedding—and what those terms actually mean.
Repointing vs. Re-bedding: What’s the Difference?
• Re-bedding involves removing the old mortar underneath your ridge caps and applying a fresh base.
• Repointing is the process of adding a new layer of mortar over the bedding to seal and protect it from moisture and movement.
Often, repointing is all that’s needed. But if the bedding itself has failed, both services may be necessary to restore your roof’s integrity.
1. Cracked or Missing Mortar Along the Ridges
Take a walk around your home and inspect the ridge lines on your roof. If you notice gaps, crumbling mortar, or pieces of mortar in your gutters, it’s a clear indicator that maintenance is overdue. Damaged mortar allows water to seep in and tiles to shift out of place.
2. Loose Ridge Caps
Ridge capping plays a vital role in keeping roof tiles secure, especially along the roof’s highest point. If the caps are moving or seem unstable, the bedding beneath may have eroded. This weakens your roof’s ability to withstand strong winds—especially during Brisbane’s storm season.
3. Leaks or Damp Patches After Rain
Water stains on your ceiling or walls after a rainstorm can be a red flag. Even minor leaks could suggest that cracks in the mortar are allowing water into your roof cavity. Addressing the problem early helps prevent more serious water damage and insulation issues.
4. Sagging Rooflines or Misaligned Tiles
Your roof should have clean, straight lines. If it appears uneven or you see tiles that look out of place, loose bedding may be the cause. Misalignment tends to worsen over time, so it’s best to fix it before it leads to structural concerns.
5. Moss, Grass, or Weeds Growing Between Tiles
Vegetation growing on your roof is more than just an eyesore—it’s a warning sign. Moss or weeds along the ridges or between tiles indicate moisture is collecting and mortar has likely broken down. Left unchecked, this can significantly reduce the life of your roof.
Don’t Ignore Early Warning Signs
What starts as a small crack can turn into a major repair if neglected. Timely repointing or re-bedding keeps your tiles secure, prevents leaks, and extends the lifespan of your roof—saving you money in the long run.
