Roof Flashing Repairs fix the metal or membrane strips that seal joins where a roof meets a wall, chimney, parapet, skylight or pipe. Failed flashing is one of the most common causes of leaks on South African homes, on both tiled and sheeted roofs. One request gets you prices from local roofers who handle this work.

Get Roofing QuotesSigns of Flashing Problems
- Leaks along a wall. Damp patches on an inside wall or ceiling next to a parapet or double-storey wall.
- Lifted or loose strips. Wind and heat can pull flashing away from the wall or sheeting.
- Cracked sealant or mortar. Old silicone and mortar fillets crack and let water behind the flashing.
- Rust or holes. Galvanised flashing rusts through, especially in coastal salt air.
- Leaks around the chimney. Water running down the chimney stack into the ceiling.
What the Work Includes
- Locating the failure. Checking the flashing, the wall above it and nearby tiles or sheets.
- Removing old material. Stripping rusted metal, failed sealant or perished membrane.
- New flashing. Fitting new strips, chased into the wall or fixed with a counter-flashing where possible.
- Sealing. Using roof-grade sealant and fixings that suit the roof covering.
- Checking nearby areas. Re-bedding loose tiles or ridge capping at the join.
Materials and Methods
- Galvanised or coated steel. Common on IBR, corrugated and Chromadek roofs. Match the coating to avoid corrosion.
- Aluminium. Lightweight and rust-resistant, often used near the coast.
- Lead or lead-substitute. Dressed over tile profiles at walls and chimneys.
- Torch-on or membrane flashing. Used where flat roofs meet parapet walls.
Repair or Replace?
Resealing can work when the flashing itself is sound. If it is rusted, short or badly shaped, new flashing is usually the longer-lasting fix. If the leak source is unclear, start with roof leak detection.

- Length of flashing. Most work is priced per metre, so long wall junctions cost more.
- Type of join. Chimneys and skylights need more cutting and shaping than straight wall runs.
- Roof height and pitch. Steep or double-storey roofs need more safety equipment and time.
- Hidden damage. Rotten timber or wet ceilings found during the job add to the cost.

Roof Flashing Repairs FAQs
Can I just add silicone to leaking flashing?
Sealant can buy time, but it cracks in the sun within a few seasons. A proper repair addresses the flashing itself.
Why does my chimney still leak after resealing?
Water may be entering through porous brickwork or a cracked chimney cap above the flashing, so ask the roofer to check the whole stack.
Does flashing come in Chromadek colours?
Yes, coated flashing is available in common roof colours, so it can match a painted or Chromadek roof.
How long does a flashing repair take?
Most single-area repairs are finished in a few hours to a day, depending on access and weather.
