Properties in Sandton are shaped by South Africa’s business capital — high-rise corporate towers and hotels sitting directly alongside large, established residential stands and new sectional-title developments, and that shows up on the roof. We assess what is actually there — the structure, the covering and the drainage — before quoting, because patching a roof that needs replacing is money spent twice.
Sandton is defined by South Africa’s business capital — high-rise corporate towers and hotels sitting directly alongside large, established residential stands and new sectional-title developments, and what people build here follows directly from that.
Sandton is governed by City of Johannesburg for building control, and by the National Building Regulations for how the work is actually built. We work to both, which is why our quotes include the approval stage rather than treating it as your problem.
Roofing & Structural Repairs services we provide in Sandton
Leak detection & repair
Tracing the entry point rather than sealing the stain, and repairing the cause.
Re-roofing & roof replacement
Full strip and replace in tile or sheeting, including new battens, underlay and flashings.
Timber & steel trusses
New truss roofs, plus repairs to sagging, rotten or borer-damaged timber and failed truss connections.
Waterproofing
Flat roofs, parapets, balconies, box gutters, valleys and the flashings where two materials meet — which is where most leaks start.
Ridging, flashings & gutters
Re-bedding and pointing ridges, replacing flashings, and installing gutters and downpipes that actually take the water away.
Ceilings after a leak
Replacing water-damaged ceilings, cornices and insulation once the roof above them is sound.
Structural repairs
Cracked walls, failed lintels, sagging beams and settlement, diagnosed with an engineer where the cause needs one.
Roof inspections & reports
A written assessment of condition and remaining life — useful before buying, and before an insurance claim.
What we see in Sandton
Business premises and trading hours
With the amount of commercial activity in Sandton, much of our work here has to happen around someone’s trading day. We schedule the disruptive stages outside business hours where we can, seal the work area properly, and hand the space back clean each morning.
Access, hours and the neighbours
Building in an estate or complex in Sandton means material deliveries booked in advance, controlled working hours, site security inductions, and neighbours a few metres away. We plan deliveries and noisy work around those constraints, because a contractor who ignores them gets the site shut down.
Ageing common areas
Common areas in older Sandton buildings are usually the least-maintained part of the property, because no single owner feels responsible. Roofs, gutters, external paint, balconies and parking are exactly where building inspections find problems and where deferred maintenance gets expensive.
Why roof leaks come back
Almost every roof we are called to in Sandton has been "fixed" at least once already. There are only a few reasons why it did not hold.
The leak was never where the stain is
Water enters at a flashing, a valley or a ridge, runs along a truss and drops somewhere convenient. Sealing the ceiling stain treats the symptom. We trace the entry point from inside the roof space first.
Sealant over a dirty surface
Waterproofing is mostly preparation. A coating applied over dust, chalk or damp will look perfect and fail within a season, which is why the cheap repair is usually the one that gets repeated.
The underlay had gone
Tiles shed most of the water; the underlay handles what gets past them. When it has perished, patching individual tiles just moves the leak. At that point a re-roof costs less than five more seasons of repairs.
Nobody looked at the structure
Sagging trusses, rot and borer damage cause leaks by changing the roof geometry. We assess the structure, not only the covering — and bring in an engineer where the timber is the actual problem.

Roofing & Structural Repairs in Sandton — your questions answered
Can you find a leak that others could not?
Usually, because we look for the entry point rather than the stain. Water travels, and a leak above a bedroom can enter the roof three metres away at a flashing or a valley. We trace it from inside the roof space first.
Should I repair or replace the roof?
It depends on the covering, the underlay and the structure. If the tiles are sound and the failures are at the details, repair. If the underlay is perished and the battens are going, you will be back every season — and we will say so rather than sell you repeated patching.
Do you work with insurance claims?
Yes. We assess and document damage in writing with photographs, which is what assessors need. We quote the repair honestly whether the claim succeeds or not.
How long does waterproofing last?
It depends on the system, the substrate and the sun. A properly prepared and correctly specified flat roof system should give you many years; a coat of sealant painted over a dirty surface will fail within a season. Preparation is most of the job.
Do you do structural work as well as roofing?
Yes — lintels, beams, crack repair and settlement work. Where the cause is structural rather than cosmetic we bring in an engineer, because a crack that is moving needs a design, not a filler.
Does a site visit cost anything?
No. We come and look, and the quote that follows is free and itemised. Nothing gets priced off a photograph or a phone call, because that is how quotes end up being revised later.
