Why ridge caps fail on Preston tile roofs
Preston's mix of period terracotta and post-war concrete-tile homes means a lot of aged ridge lines, and aged ridges are where these roofs leak first. The original cement bedding cracks and crumbles over the decades, the caps loosen, and water finds its way in behind them. Repointing fixes it properly: we re-bed the caps that have moved on fresh mortar, then re-point the ridge and hip lines with a flexible compound that moves with the roof rather than cracking like the old cement. On Preston's period terracotta we colour-match the pointing so the repair suits the character of the home, and where only the ridges have failed we do the repoint on its own rather than pushing a full restoration.
On Preston's older terracotta homes the ridge capping is often the oldest, most weathered part of the roof, so it is usually the first thing to fail and let water into the cavity — well before the tiles themselves give out.

Roof weather in Preston
Melbourne's swing from hot days to cold, wet ones works rigid old mortar loose, and with rain on roughly ~120 days a year, cracked pointing in Preston 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 Preston
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
Preston roof repointing — your questions
Yes. On Preston's period homes we re-bed and re-point the terracotta ridge caps and colour-match the pointing so it suits the roof. Flexible pointing is used so it does not crack again the way the original cement did.
The original rigid cement cannot handle the roof expanding and contracting through Melbourne's hot and cold swings, so it cracks. Flexible pointing compound moves with the roof instead, which is why it stays sealed far longer.
If the tiles are sound and only the ridge lines have failed, a repoint is the right fix. If the tiles are also porous or fading, a restoration may be better value. We look and tell you honestly which yours needs.
