Most roof leaks are a detail failure rather than a roof failure: a flashing, a lap, an outlet, a cracked tile.
Fixing the detail is a few thousand rand. Recovering the roof is not. Tracing services at Leak Detection Pretoria.
Send photos of the roof and the ceiling stain if you can get them safely.

| Roof | Usual failure and fix |
|---|---|
| Concrete or clay tile | Cracked and slipped tiles, perished ridge bedding, blocked valleys. Replace and repoint. |
| IBR and corrugated sheet | Failed screw washers, rusted laps, cut-edge corrosion. Refix, seal laps, treat rust. |
| Flat and torch-on | Failed upstands, blistering, ponding at outlets. Patch, or recover the section. |
| Slate and shingle | Slipped and broken units, failed underlay. Replace units, address the underlay. |
Coastal Roofs
Highveld hail splits sheeting and cracks tiles, and the UV load on an inland roof degrades sealants and membranes faster than most owners expect. Specify hail-rated sheeting and UV-stable coatings; a cheap sealant on a Pretoria roof can perish within a season or two.

Ask for the guarantee in writing and what it covers. Roof repair guarantees vary from three months on a patch to ten years on a full membrane system, and that difference is most of the value.

Frequently Asked Questions
How much does a roof leak repair cost?
Most single-defect repairs land between R800 and R5,000, with flashing and valley work at the upper end. Full flat roof waterproofing is a different scale of job, around R12,000 to R24,000 for a 40 m² section in torch-on.
Is roof damage covered by insurance?
Sudden storm damage is generally covered. Deterioration, rust and failed maintenance usually are not. Photographs dated to the storm help considerably.
How long should a roof repair last?
A properly executed flashing or tile repair should last the remaining life of the roof. A sealant smeared over a stain lasts one season, which is why the cheapest quote is so often the most expensive over three years.
