Why ridge caps fail on Thornbury tile roofs
Thornbury's Edwardian and bungalow-era roofs carry ridge lines a century old in many cases, and the bedding and pointing are usually the first things to fail. The original cement has cracked and crumbled over the decades, the caps have loosened, and water works in behind them. Repointing re-secures the ridge line: we re-bed the caps that have moved, then re-point with a flexible compound that flexes with the roof instead of cracking, colour-matched to suit a period roof. It's careful work that keeps water out without disturbing the character of the home below.
Thornbury's century-old terracotta ridge lines have often been patched before with rigid cement that's since cracked again — flexible, colour-matched pointing is what finally holds on these old ridges.

Roof weather in Thornbury
Melbourne's swing from hot days to cold, wet ones works rigid old mortar loose, and with rain on roughly ~125 days a year, cracked pointing in Thornbury lets water into the roof long after the storm passes.

The process
How a True Roof repointing job works
2
Re-bed where needed
Caps that have lifted or lost their bedding are re-set on fresh mortar so they sit true and secure.
3
Re-point with flexible compound
A flexible pointing compound is applied over the bedding — it moves with the roof through heat and cold instead of cracking like old cement.
4
Finish & check
We colour-match the pointing, clean up, and confirm the whole ridge line is sealed and secure.
Roof types in Thornbury
Repointing applies to tiled roofs — terracotta and concrete — where the ridge and hip caps are mortar-bedded. It is often done as part of a full restoration, but a stand-alone repoint is the right call when the tiles are otherwise sound and only the ridge lines have failed.
Our standard
Our repointing uses a flexible pointing system and is backed by a 7-Year Workmanship Guarantee and a 10-Year Dulux Acratex Material Warranty.

Cracked mortar is a slow-motion interior flood.
A hairline crack in ridge pointing looks minor. But every Melbourne downpour pushes water through that gap and into the roof cavity. Over months, insulation gets waterlogged, plaster softens, and ceiling cornice begins to fail. By the time the stain appears on your ceiling, the damage has already spread further than you can see. Repointing the ridge today, for a fraction of the cost, closes the door on that entire cascade before it starts.

What Melbourne homeowners say
Thornbury roof repointing — your questions
Yes. We re-bed and re-point period terracotta ridge lines with flexible, colour-matched pointing that suits the roof, using materials that won't crack again the way the original cement did.
Almost always because rigid cement was used, which can't handle the roof moving through heat and cold. We use flexible pointing that flexes with the roof, so it holds where the old mortar failed.
On many Thornbury period roofs the tiles are sound and only the ridge lines have failed, so a repoint is the right fix. If the roof needs more, we'll say so.
