A roof leak is almost never where the water appears. It runs along a truss, across a ceiling and drops somewhere convenient, which is why so many leaks are sealed three times and still leak. We find where the water actually gets in.
Randburg is defined by a broad, mostly residential belt of 1960s–80s freestanding homes now mixed with townhouse complexes and busy neighbourhood retail strips, and what people build here follows directly from that.
Because Randburg sits within City of Johannesburg, the approval route, the building-line rules and the occupancy certificate all run through them. We manage that submission as part of the contract rather than leaving you to chase it.
Roofing & Structural Repairs services we provide in Randburg
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 Randburg
Layouts built for a different way of living
Houses in Randburg were planned around separate rooms, small kitchens and a formal lounge nobody now uses. The structure is usually sound; the plan is what is wrong. Most of the value in renovating here comes from removing the right two or three walls — which means knowing which ones are carrying the roof.
Buildings that work harder than houses
Industrial and commercial premises in Randburg take punishment domestic buildings never see: forklift traffic on floors, constant use of ablutions, roofs spanning far greater areas. Specifying a domestic solution in that environment is a false economy, and it is the most common reason we are called back to a building someone else refurbished.
Where the unit ends and the scheme begins
In sectional-title developments around Randburg, the most expensive disputes are about which side of the boundary a defect sits on. A roof leak, a drain or an external wall is often common property, not yours. Before we quote we establish who owns the problem, so you are not paying for the scheme’s repair out of your own pocket.
Why roof leaks come back
Almost every roof we are called to in Randburg 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 Randburg — 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.
Who does the electrical work?
Our electrical arm, Sirius Bright, handles the electrical installation and issues the Certificate of Compliance for it. It means the certification is done by people who do it daily rather than subcontracted out and chased later.
