When it comes to storm protection, most homeowners think of gutters, drainage, or flashing — but ridge capping plays one of the most critical roles in keeping your roof safe and watertight.
Especially for tile roofs in coastal Queensland, poorly maintained ridge capping can lead to water ingress, structural damage, and fast erosion during summer storms.
Here’s why it matters — and what you need to do about it.
What Is Ridge Capping?
Ridge capping refers to the curved or angled tiles that sit at the peak of your tile roof — where two roof faces meet.
These tiles are: - Held in place by mortar (which can crack over time) - Sealed to prevent water entry - Vulnerable to wind, movement, and moisture
How Ridge Capping Protects Your Home
- Prevents water from seeping into your roof cavity
- Seals the vulnerable highest points of your roof
- Maintains structural integrity under high winds
- Stops tile movement during strong weather
“We see more leaks start at ridge capping than almost any other point on tile roofs — especially after storms.”
Common Ridge Capping Issues in Coastal Homes
- Cracked or missing mortar (pointing)
- Loose or shifted capping tiles
- Water stains or leaks inside after storms
- Accelerated wear due to salt and sun exposure
Why Storms Accelerate Ridge Capping Damage
- Wind uplifts capping tiles if pointing is weak
- Heavy rain finds its way into cracks
- Salt air dries and weakens old mortar
- Heat expands and shifts poorly set tiles
That’s why pre-storm repointing is one of the best preventative investments you can make.
How to Maintain Ridge Capping
- Have it inspected every 2–3 years in coastal areas
- Repoint every 10–12 years (more often if near sea air)
- Look for signs of movement or cracking
- Always repoint as part of a full roof restoration
Why JMZ Repoints Better
- 30+ years of tile roof restoration
- Use of high-bond, flexible pointing materials
- Clean, even finish with improved visual appeal
- Local teams with coastal repointing experience
We don’t cut corners — especially at the top of your roof.
