Roof Ridge Repairs Cape Town deals with the capping along the top and hips of a roof: cracked mortar, loose or slipped ridge tiles and the leaks they cause. Get prices from roofers who repoint and rebed ridges as routine work.
The ridge is the highest, windiest part of any roof, and the mortar holding the ridge tiles is normally the first part of a tile roof to give out. Sorting it early costs little, while ignoring it lets water into the roof structure at its weakest spot.
About how many metres of ridge and hip there are, and whether any capping is loose.

| Method | What it involves | Life span |
|---|---|---|
| Repointing | Raking out and renewing the visible mortar joint only | 5 – 10 years with sand-cement |
| Repointing with flexible compound | Same, using a polymer-modified pointing product | 10 – 20 years |
| Rebedding | Capping raised off, bedding mortar renewed underneath, capping relaid | 10 – 20 years |
| Mortar-free dry ridge | Mechanically fixed capping with an aired roll, no mortar | 25 years plus |
| Metal ridge capping | Sheet metal capping with closures, used on sheeted roofs | 20 – 40 years |
Repointing only looks tidy if the bedding below has failed. If a ridge tile lifts or rocks when you push it, new pointing will not keep it in place and the ridge has to be rebedded. That difference explains why two quotes for the same ridge can be three times apart.
What Makes Ridge Mortar Crack
- Heating and cooling. The ridge heats up and cools down more than any other part of the roof, and rigid sand-cement cannot flex.
- Wind exposure. The apex takes the complete force of the south-easter, working at anything by now loose.
- Age and the original mix. A weak or sandy mix crumbles long before a properly proportioned one.
- Roof movement. Settlement and truss deflection over many years opens joints at the ridge first.
- Earlier patch jobs. Fresh mortar smeared over cracked bedding does not bond well and lifts within a season.

Ballpark Cape Town figures, not firm quotes. The combined length of ridges and hips is normally more than owners think, since the hips on a complicated roof can total more metres than the main ridge. Measure both when you compare prices.
Ask whether the quote is for repointing or for rebedding, because they are different jobs.
Compare Ridge Repair QuotesVentilating At The Ridge
A traditional ridge bedded in mortar closes the top of the roof completely, which is exactly where warm, damp air from the roof void would otherwise escape. Dry ridge systems come with a ventilated roll, so replacing a failed mortar ridge is an easy chance to improve airflow too. This counts most on insulated roofs where condensation in the roof void is a genuine problem. See roof ventilation in Cape Town.
Sort This Out Before Painting
Do ridge repairs before the roof is painted, not afterwards. Repointing after painting leaves new mortar showing against the fresh coat and damages the finish along the entire ridge. If both jobs are planned, schedule the repairs first and get one quote for the two.
Common Questions
How can I tell if the ridge needs repointing or rebedding?
If the mortar has cracked but the capping is still firm, repointing will do. If you can lift or rock a ridge tile by hand, the bedding below has failed and pointing alone will not keep it in place.
What does ridge repointing cost in Cape Town?
Approximately R180-R320 a metre with sand-cement and R280-R480 with a flexible compound. A usual home with 25 metres of ridge and hip lands around R6,500-R16,000 depending on method.
What lifespan does ridge pointing have?
Sand-cement pointing often lasts five to ten years in Cape Town conditions. Flexible polymer-modified compounds normally last ten to twenty because they shift with the roof instead of cracking.
What does a dry ridge system consist of?
Mechanically fixed ridge capping using clips and a vented roll instead of mortar. It costs extra upfront, lasts substantially longer, and ventilates the apex, which mortar bedding does not.
Can a cracked ridge let water in?
Yes. The ridge is the highest part of the roof, and water getting in there can run the whole length of the structure before it shows on a ceiling, often far from the ridge.
Should ridge lines be repaired before painting the roof?
Yes. Doing it later leaves fresh mortar against a new coat and disturbs the finish along the entire apex. Sequence the repairs first and have both quoted at the same time.
Are hips priced the same as the main ridge?
A metre, yes. What unexpected extras homeowners is the total length, because hips on a complex roof frequently add up to more metres than the main ridge does.
What is the normal timeframe for ridge work?
On an average house, repointing takes one to two days and rebedding two to three, plus time for a cement-based product to cure before rain.
Ridge repairs are a common preventative project requested through Roof Repairs Cape Town, normally ahead of the winter rainfall.
