Roof leak detection and assessment

Roof leaks rarely appear directly above the wet patch you see inside. We inspect the roof surface, valleys, flashings, ridges, vents, geyser outlets and gutters to trace the water back to its entry point before any work starts.

Getting the diagnosis right means the repair is done once, not repeatedly.

  • Tile roof leak detection
  • Valley, flashing and ridge inspections
  • Geyser and vent pipe penetrations
  • Ceiling and internal damage tracing

House roof waterproofing systems

Depending on the roof type and condition, we apply torch-on bitumen membranes, liquid waterproofing coatings, or repair and re-seal specific areas. Flat roofs, parapet walls and hidden box gutters get particular attention because they hold water.

  • Liquid roof coating applications
  • Parapet and box gutter sealing
  • Tile roof re-bedding and pointing

Roof repairs that stop recurring leaks

Failed flashings, cracked ridge capping, blocked valley channels and loose tiles all let water in during heavy Johannesburg storms. We repair the actual source so the leak stops instead of moving to another part of the ceiling.

Ceiling and plumbing leak crossover

Some ceiling stains come from the geyser or supply pipe, not the roof. We confirm whether the water is roof-runoff or plumbing-related before waterproofing, so you do not pay for a roof repair when the problem is a leaking pipe or geyser tray.

House Roof Waterproofing: common questions

How do I know if my ceiling stain is from the roof or a plumbing leak?
Roof leaks usually worsen during or after rain and may follow a line from the highest point. Plumbing leaks are often constant, warm if they are hot-water pipes, and show a moving water meter. We test to confirm the source before quoting.
Do you waterproof tile roofs or only flat roofs?
Both. Tile roofs need re-bedding, pointing, valley repairs and flashing work. Flat roofs, parapets and box gutters typically need a membrane or liquid coating system.
How long does roof waterproofing last?
A properly applied membrane can last many years, but it depends on the product, roof movement and maintenance. We use quality materials suited to the roof type and explain what to expect.
Can you fix the ceiling damage too?
We stop the leak and make the area sound. Ceiling repairs, repainting and full reinstatement can be quoted as part of a broader renovation if needed.
