Roof Pointing vs Re-Bedding in Brisbane: What's the Difference?

If you've had a quote for roof pointing in Brisbane, you may have seen "re-bedding" listed alongside it and wondered whether you're being charged twice for the same thing. You're not. Bedding and pointing are two distinct layers that work together to hold and seal the ridge and hip caps on a tiled roof. They're easy to confuse because you see them in the same spot, on the same caps, but they do different jobs, and they wear out at different rates.

What is roof re-bedding?

Bedding is the mortar bed that the ridge caps and hip caps sit on. It's a sand-and-cement mix laid along the apex of the roof to set each cap firmly in place and bridge the gap between the rows of tiles. Over time, and Brisbane's heat, storms and movement speed this up, that mortar cracks, crumbles and loses its grip, leaving caps loose or rattling. Re-bedding means removing the old, failed mortar and laying a fresh bed so the caps are solidly seated again. It's the structural part of the job.

What is roof pointing?

Pointing is the flexible compound applied over the bedding to seal and finish it. Modern pointing uses a flexible polymer-based compound (rather than plain mortar) that bonds the cap to the bedding, seals out water, and flexes with the natural expansion and contraction of the roof instead of cracking. When people talk about roof pointing in Brisbane, this is usually the visible top layer they mean, the neat line of colour running along the ridge. Good pointing is what keeps wind-driven rain from getting under the caps during a storm.

Why your roof needs both

Here's the part that surprises people: pointing on its own can't fix a failed bed. If the mortar underneath has crumbled, fresh pointing applied over the top has nothing solid to bond to, so it lifts and fails early. Likewise, new bedding without proper pointing is left exposed to weather and won't stay watertight. That's why a thorough roof restoration almost always includes both, re-bedding to re-seat the caps and pointing to seal and protect them.

• Bedding is the mortar base the caps sit on; pointing is the flexible seal over the top.
• Re-bedding fixes loose or rattling ridge and hip caps.
• Pointing seals out wind-driven rain and flexes instead of cracking.
• Pointing applied over failed bedding has nothing solid to bond to and fails early.
• A proper restoration does both together so the caps stay secure and watertight.

If your ridge caps are loose, your pointing is cracked, or you're simply not sure what's going on up there, a quick inspection will tell you whether you need targeted roof repairs or a full restoration. We'll explain what we find in plain language and give you an honest, free quote.
