Roof Repairs Sandton - compare quotes for flat roof waterproofing, leaks, slate and clay tile repairs, hail damage, apartment block roofs and commercial roof repairs.
Sandton roofs lean heavily towards flat concrete slabs on modern houses, apartment blocks and offices, with premium pitched materials on older large homes, so waterproofing and detailing make up much of the work.

Where Flat Roofs Leak
- Upstands and parapets. Membrane not taken high enough, or failed where it turns up the wall.
- Rainwater outlets. Leaves and dust block outlets, and a summer storm pools water behind them.
- Plant and penetrations. Aircon units, solar mounts and ducting cut in after construction and poorly flashed.
- Balcony and terrace junctions. Reported as roof leaks, often a threshold or balcony upstand.
- Expansion joints. Large slabs move between hot afternoons and cold nights, and rigid detailing cracks.
For a building with several roof areas, get one survey and scope before collecting quotes.
Compare Sandton QuotesRoof Repairs Sandton Apartment Blocks
On sectional title blocks the roof is common property, so trustees need comparable quotes to motivate spend from the reserve fund or a special levy. What works is a written condition survey producing a single scope, quotes priced against that scope, and a phasing plan owners can see. Where a block has been patching the same membrane every storm season, adding up three years of repair spend plus internal reinstatement and comparing it with a strip and re-waterproof usually settles the decision.
Frequently Asked Questions
What does flat roof waterproofing cost in Sandton?
Torch-on runs R280 to R550 per square metre and strip and re-waterproof R380 to R750. Access on a tall building is priced separately.
Torch-on or liquid membrane?
Torch-on suits large open slabs. Liquid-applied suits roofs with many penetrations, plant bases and awkward details.
Why is access so expensive on blocks?
Height, street-side scaffolding, and handling material on buildings with no roof access route. It is a genuine cost.
Who pays for a leak into a top-floor flat?
Normally the body corporate, as the roof is common property. Check the scheme rules for internal reinstatement.
Should solar mounts be flashed by a roofer?
Yes. Penetrations through a membrane should be detailed by someone who guarantees the waterproofing, not only the panels.
How often should flat roof outlets be cleared?
At least once before the summer storms, more where trees overhang.
Are slate roofs repairable?
Yes. Individual slates are replaced and hooked or nailed in, provided a contractor with slate experience does it.
