Roof Repointing Melbourne
Roof repointing across Melbourne.
The mortar holding your ridge capping does not last forever. When pointing cracks and bedding breaks down, caps come loose and water gets in at the highest point of the roof. We re-bed and re-point with flexible compounds made for the job.

Ridge capping, bedded and pointed right.
Bedding and pointing, explained
Ridge and hip caps are held by two layers. The bedding is the mortar the cap actually sits on, and the pointing is the weather seal applied over the bedding edge. On older Melbourne roofs both were done in rigid sand-and-cement mortar, which is exactly why both eventually fail. Knowing which layer has gone is the difference between a proper quote and a guess.
Why the old mortar cracks
Roofs move constantly. Tiles expand in the afternoon sun and shrink at night, the frame settles, and wind works on the ridge line. Rigid mortar cannot move with any of that, so it cracks, then crumbles, then lets go. Melbourne’s big temperature swings make it worse. The first signs are hairline cracks along the pointing and grit washing into the gutters.
Repointing or rebedding?
If the bedding is sound and only the pointing has cracked, a repoint is enough. If the caps rock when pressed or have drifted out of line, the bedding underneath has failed and the caps need lifting and re-bedding on fresh mortar first. Plenty of cheap quotes skip that question and point over loose caps, which looks fine for a year and then fails. We check every cap and quote what the roof actually needs.
Flexible pointing compounds
Modern pointing is a flexible acrylic polymer compound, not mortar. It bonds to both the cap and the bedding, stays slightly elastic for years and moves with the roof instead of cracking. It comes in a full colour range so the new pointing matches your capping. Applied at the right thickness over sound bedding, it is the lasting fix for a problem rigid mortar could never solve.
Storm damage and loose caps
When a front comes through Melbourne, caps with failed bedding are the first thing to move. A loose ridge cap in a storm is both a leak and a falling hazard. If your ridge line has shifted after wind, treat it as urgent. We make it safe, re-bed what has moved and point the line properly.
Why early repointing matters
The ridge is the highest point of the roof, so water that enters there can travel anywhere below it. Repointing is one of the cheapest jobs in roofing relative to what it prevents, and it is the single most common fix behind the leaks we attend across Melbourne’s tiled suburbs. Left alone, failed pointing becomes failed bedding, and failed bedding becomes caps on the ground.
