Roof Ridge Repairs Cape Town covers the capping along the apex and hips of a roof: cracked mortar, loose or displaced ridge tiles, and the leaks that follow. Compare quotes from contractors who repoint and rebed ridges regularly.
Ridges are the highest and most wind-exposed part of a roof, and the mortar bedding them is usually the first thing on a tile roof to fail. Attending to it early is cheap; leaving it lets water into the roof structure at its most vulnerable point.
Roughly how many metres of ridge and hip, and whether 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 lifted off, bedding mortar renewed underneath, capping relaid | 10 – 20 years |
| Dry ridge system | Mechanically fixed capping with a ventilated roll, no mortar | 25 years plus |
| Metal ridge capping | Sheet metal capping with closures, used on sheeted roofs | 20 – 40 years |
Repointing is cosmetic if the bedding underneath has failed. Where you can lift a ridge tile by hand or rock it, pointing will not hold it and the ridge needs rebedding. That distinction is the main reason two ridge quotes can differ by a factor of three.
Why Ridge Mortar Cracks
- Thermal movement. The ridge heats and cools more than any other part of the roof, and rigid sand-cement has no give in it.
- Wind exposure. The apex takes the full force of the south-easter, working at anything already loose.
- Age and mix. A weak or over-sanded original mix crumbles well before a correctly proportioned one.
- Roof movement. Settlement and truss deflection over decades opens joints at the ridge first.
- Previous patching. New mortar smeared over old cracked bedding bonds poorly and lifts within a season.

Indicative Cape Town ranges, not quotations. Total ridge and hip length is usually more than owners estimate, because hips on a complex roof can add up to more metres than the main ridge. Measure both when comparing quotes.
Ask whether you are being quoted for repointing or rebedding, because they are not the same job.
Compare Ridge Repair QuotesRidge Ventilation
Traditional mortar-bedded ridges seal the apex completely, which is where warm moist air from the roof space would naturally escape. Dry ridge systems include a ventilated roll, so replacing a failed mortar ridge is a convenient moment to improve airflow at the same time. That matters more on insulated roofs where condensation in the roof space is a real issue. See roof ventilation in Cape Town.
Do It Before Painting
Ridge work should be done before a roof is coated, not after. Repointing after painting leaves fresh mortar visible against the new coating, and disturbs the finish along the whole apex. Where both are planned, sequence the repairs first and have them quoted together.
Frequently Asked Questions
How do I know if my ridge tiles need repointing or rebedding?
If the mortar is cracked but the capping is firm, repointing is enough. If a ridge tile can be lifted or rocked by hand, the bedding underneath has failed and pointing alone will not hold it.
How much does ridge repointing cost in Cape Town?
Roughly R180 to R320 per metre with sand-cement and R280 to R480 with a flexible compound. A typical house with 25 metres of ridge and hip lands around R6,500 to R16,000 depending on method.
How long does ridge pointing last?
Sand-cement pointing commonly lasts five to ten years in Cape Town conditions. Flexible polymer-modified compounds typically last ten to twenty because they move with the roof instead of cracking.
What is a dry ridge system?
Mechanically fixed ridge capping using clips and a ventilated roll instead of mortar. It costs more upfront, lasts considerably longer, and ventilates the apex, which mortar bedding does not.
Can a cracked ridge cause a leak?
Yes. The apex is the highest point of the roof and water entering there can run the full length of the structure before it shows on a ceiling, often well away from the ridge itself.
Should ridges be repaired before painting the roof?
Yes. Doing it afterwards leaves fresh mortar against a new coating and disturbs the finish along the whole apex. Sequence the repairs first and have both quoted together.
Do hips cost the same as the main ridge?
Per metre, yes. What surprises owners is the total length, because hips on a complex roof frequently add up to more metres than the main ridge does.
How long does ridge work take?
A typical house is one to two days for repointing and two to three for rebedding, plus curing time before rain if a cement-based product is used.
Ridge repairs are a common preventative job requested through Roofing Contractors Cape Town, usually ahead of the winter rainfall.
