If the mortar under your ridge caps is cracking or crumbling, your roof is no longer sealed the way it should be. Roof repointing and rebedding — also known as ridge cap restoration — resecures and reseals the ridge capping on a tiled roof to keep it watertight and structurally sound. In most cases, repointing alone fixes the problem; rebedding (partial or complete) is only needed where the mortar bedding itself has been damaged.
Roofing Hobart Pty Ltd (Licence 505200030) carries out this work across greater Hobart and Southern Tasmania, on residential and commercial tiled roofs. It’s one of the most common repairs we’re called out for — and one of the most common ways older tiled roofs fail quietly, until a leak shows up inside the house.

Getting this right depends on two things: correctly mixed, structurally sound bedding to begin with, and pointing that’s kept in good repair afterward to stop water getting in. Sound bedding with failing pointing will eventually let water through and start to degrade; pointing that fails on bedding that’s still sound can usually just be repointed on its own.
Rebedding only comes into it once the bedding itself is damaged — from long-term water ingress or an incorrectly mixed original pour. Where the damage is limited to a few sections, a partial rebedding can keep costs down. But if the pointing has gone unmaintained for a long period, the damage is usually widespread enough that a full rebedding is required as well. We confirm which applies after inspecting in person.

A professional step-by-step approach for a roof that’s built to last.
Every ridge cap is checked individually, including the pointing and the mortar bedding underneath.
Pointing, and bedding where damaged, fully removed rather than covered over.
Affected sections rebedded with correctly proportioned, fresh mortar. Flexible pointing compound applied to seal the joint and allow for roof movement.
Modern flexible pointing compounds are generally more resistant to the cracking that affects traditional lime mortar under repeated temperature cycling, which is part of why we recommend it as the standard approach for Hobart's climate rather than like-for-like mortar replacement.
It depends on roof size, how much ridge capping needs attention, and whether repointing alone will do it or rebedding's needed too. We provide a free quote after inspecting in person.
Not recommended — getting the mortar mix right, working safely at height, and correctly assessing what actually needs replacing all take experience. A poorly done repoint often fails faster than the one it replaced.
At least every 10 years, even without an obvious leak. Left unaddressed, water ingress through the ridges can lead to rotting roof timbers, mould in the roof cavity, and in some cases reach electrical wiring — increasing the risk of an electrical fault. Waiting for a visible leak usually means the damage, and the cost, is already well beyond the ridge line.
