Get Waterproofing QuotesWhere Roofs Usually Leak
- Flashings. Where the roof meets walls, chimneys, parapets and pipes.
- Laps and screws. Metal sheet overlaps and rusted or loose screws.
- Ridges and valleys. Cracked ridge mortar and blocked or rusted valleys.
- Outlets and gutters. Blocked downpipes and box gutters that overflow.
- Membrane damage. Split, blistered or lifted torch on and coatings.
- Penetrations. Solar mounts, aerials, vents and geyser pipes.
Finding the Leak
Water often shows inside far from where it enters.
- Roof space check. Tracing stains and wet timber back to the entry point.
- Roof inspection. Checking details, joints and fixings from above.
- Water testing. Wetting one section at a time to confirm the source.
- Moisture meter. Mapping wet areas in ceilings and slabs.
Repair or Re-waterproof
- Spot repair. Fits when one detail has failed and the rest of the roof is sound.
- Section repair. Fits when one area, such as a valley or parapet, has failed.
- Full re-waterproof. Fits when the system is old, cracked or leaking in many places.
The right repair depends on what the inspection finds. Sealant over a failed detail is usually a short-term fix.

- Finding the source. Hard-to-trace leaks take more time and testing.
- Access. Steep, high or fragile roofs need ladders, scaffolding or roof boards.
- Extent. One failed detail costs far less than a failed system.
- Urgency. Emergency or after-hours call-outs may cost more.
How a Leak Repair Works
- Report. You say where water shows inside and when it leaks.
- Inspect. The contractor checks the roof space and the roof.
- Confirm. The entry point is confirmed, by water test if needed.
- Repair. The failed detail is fixed with a suitable system.
- Recheck. The area is checked after the next rain.
Before the Contractor Arrives
- Photos. Take photos of stains and drips inside.
- Timing. Note whether it leaks in all rain or only wind-driven rain.
- Access. Clear the roof hatch and the area below the leak.
- Protect. Move furniture and put buckets under drips.
Questions to Ask
- Cause. Where exactly is the water getting in?
- Scope. Is this a spot repair or is the system failing?
- Method. What materials will be used on the detail?
- Comeback. What happens if it still leaks after the repair?
Roof Leak Repairs FAQs
Why does the leak show far from where it enters?
Water runs along slabs, sheets and timber before it drips, so the stain is often metres away from the entry point.
Can a roof leak be fixed while it is raining?
A contractor can often make a temporary fix, but most permanent repairs need a dry surface.
Is silicone a good leak repair?
Rarely. Silicone and general sealants often fail on roofs. A proper flashing, membrane patch or reinforced coating usually lasts longer.
How much does a roof leak repair cost?
Small repairs usually cost about R1,500 to R5,000, plus a call-out of about R500 to R1,500 if it is charged separately.
When should I re-waterproof the whole roof?
When leaks keep appearing in different places or the membrane is cracked and blistered across the roof.
