7 Signs Your Sydney Roof Needs Repointing (Before It Leaks)
Failed pointing is the single most common roofing issue we see in Sydney. The good news: you can spot every warning sign from the ground — no ladder, no risk, no salesperson required.
The 7 signs to watch for
1. Mortar fragments in your gutters or garden beds
Small grey or beige crumbs in the gutter after a storm are pieces of the bedding mortar breaking down. It's the earliest warning sign.
2. Hairline cracks along the ridge line
Look up at the ridge cap line from across the street. Cracks running in a straight line mean the rigid mortar has lost its bond.
3. Visibly lifted or slipped ridge caps
A cap sitting even 5mm out of line lets driving rain straight in.
4. Stains on the underside of eaves
Brown tea-stain marks on the underside of your eaves are water tracking down the rafters.
5. Moss or lichen along ridge lines
Moss holds moisture against the mortar and accelerates breakdown.
6. Daylight visible through the roof from inside the cavity
If you can see pinpricks of daylight from inside the roof space, water is getting in too.
7. Rising insurance excess on roof claims
If your insurer has flagged the roof as ageing, repointing now is cheaper than a future excess.
How long do you have once you see the signs?
| Sign | Typical time before internal leak |
|---|---|
| Mortar fragments only | 2 – 4 years |
| Hairline cracking | 12 – 24 months |
| Lifted ridge caps | Next major storm |
| Internal ceiling stain | Already leaking |
FAQ
Can I repoint just one section?+
Yes, but it's rarely cost-effective. Once one section has failed the rest is usually 1–3 years behind.
How long does fresh pointing last?+
Flexible pointing properly installed lasts 15–20 years. Rigid mortar-only pointing fails in 8–12.
