Roof & Balcony Slab Waterproofing in Vereeniging
Location: Vereeniging, Gauteng
Service: Roof Slab & Balcony Slab Waterproofing (ArmTec HyperFlex System)
This case study looks at a double-storey home with two exposed concrete slabs working against it: a flat roof slab and an upstairs balcony slab, both structurally sound but neither properly sealed against summer downpours. With turnups, outlets, and slab edges left vulnerable, it was only a matter of time before water found its way in. A SealPro-approved applicator was brought in to waterproof both slabs before the damage could spread into the structure below.
The problem the homeowner was facing
Standing water was already pooling against the parapet wall at roof level, sitting for long enough to leave dark staining and silt across the slab surface. Around the turnups and outlets — the weak points where water pressure concentrates first — the substrate had no membrane protection at all. On the balcony slab, the same risk existed one floor down, directly above living space, where a slow leak is far harder to spot until it shows up as a stain on a ceiling. Left untreated, both slabs would have continued absorbing moisture through hairline cracks and unsealed joints, risking damp patches, reinforcing steel corrosion, and costly interior repairs.
The waterproofing solution
The crew approached both slabs with the same disciplined sequence, using the ArmTec waterproofing system as an approved SealPro applicator:
- Prep and prime the substrate — the roof and balcony slabs were cleaned back to a sound surface and primed to give the waterproofing membrane a surface it could properly key into.
- Strengthen turnups and outlets — every turnup and outlet was reinforced with a stretch-seal membrane, closing off the exact points where roof leaks typically start.
- Apply the ArmTec waterproofing system — a fibre-reinforced membrane was rolled out across the full roof slab and balcony slab, tying the parapet turnups into a single, continuous waterproof layer.
- Finish the balcony with a tile-ready topcoat — since the balcony doubles as a walked-on surface, a tile-ready topcoat was applied over the membrane, giving it a durable, textured finish ready for foot traffic or tiling.
The result
Both slabs now carry a continuous, reinforced waterproof membrane from the parapet edges right across the deck, with the balcony finished in a tough, tile-ready surface that can take daily use. The ponding and staining that had built up at the roof edge is gone, and the turnups and outlets — the areas most likely to fail first — are fully sealed. The homeowner now has two fully protected concrete slabs backed by manufacturer warranty on the ArmTec system.

Commercial IBR Metal Roof Waterproofing in Vereeniging
Location: Vereeniging, Gauteng
Service: IBR Metal Roof Maintenance & Waterproofing (Commercial)
A large commercial IBR sheet-metal roof had reached the point where its original coating was breaking down. The owner needed the roof stripped back to sound metal, every leak path sealed, and the whole surface re-coated so the building was protected and looking sharp again — a job carried out across the full roof, plus remedial work to the surrounding walls.
The problem: rust, failing overlaps and worn coating
Years of sun, wind and rain had taken their toll on the IBR sheeting. Rust had broken through along ridge caps, sheet overlaps and around screw fixings, spreading in tell-tale orange streaks down the pans. The old coating had chalked and thinned, several joints and screw lines were no longer watertight, and moisture was tracking into the structure. Left unattended, corrosion like this eats through metal sheeting and turns a maintenance job into a full re-sheet.
The solution: a full remedial coating system
Following a proven metal-roof remedial sequence:
- High-pressure clean and degrease the entire roof to strip chalk, dirt and loose material back to a sound surface.
- Treat all rusted sections with a rust converter to neutralise corrosion, then spot-prime the bare metal with a purple metal primer.
- Seal every overlap, joint and screw line — the primary leak paths — bedding a flexible reinforcing tape into the seams and capping each fastener with a dedicated screw-seal compound.
- Apply a high-build waterproofing membrane across the treated areas to lock everything in as one continuous, flexible skin.
- Finish with two coats of high-quality roof paint for UV protection, a uniform colour and long service life.
Scaffold-tower access and a full health-and-safety file kept the crew working safely at height throughout, and the adjoining walls were prepped and repainted to match.
The result: a sealed, protected roof built to last
The finished roof is watertight, corrosion-free and finished in a clean, uniform coat that lifts the whole building. Overlaps, ridges and screw lines are sealed, the rust is gone, and the client has a durable coating system with a workmanship guarantee behind it — turning a deteriorating roof back into a low-maintenance asset for years to come.
This case study reflects the standard remedial process used on rusted IBR and metal roofs across the region — the same system applied on request in Vereeniging and surrounding areas.

Tile Roof Ridge Waterproofing & Full Repaint in Vereeniging
Location: Vereeniging, Gauteng
Service: Tile Roof Ridge Waterproofing & Full Roof Repaint
This double-storey tiled roof had reached the point where age was starting to show. Cracked ridge cappings, missing pointing, and a handful of broken tiles had left the roof vulnerable to leaks, while the overall finish had faded and dulled over the years. The homeowner called in SealAll Roof Contractors to rebuild the ridge line, seal off the vulnerable points, and refresh the entire roof with a durable coating.
The problem was cracked ridges and a tired, faded finish
Up close, the ridge cappings told the real story. The cement pointing between the ridge tiles had cracked and, in places, crumbled away completely, leaving open gaps along the roofline. One ridge section had slipped out of place entirely and needed to be rebuilt from scratch. Scattered tiles across both the older and newer sections of the roof were cracked or broken, and several had slipped on the flashing. Left unaddressed, gaps like these are exactly where water finds its way into the roof structure during Highveld summer storms.
The SealAll solution: rebuild, waterproof, repaint
The crew worked through the roof section by section:
- Prep and rebuild – Loose, cracked cement was raked out of the ridge joints and the slipped ridge section was fully rebuilt using the existing tiles on site. Broken and slipped tiles were replaced and resealed.
- Prime and waterproof the ridges – The prepped ridge substrate was primed, then sealed using a Stretch Seal ridge waterproofing system, an elastomeric membrane built to flex with the roof rather than crack again under thermal movement.
- Wash and prep the full roof – Every section of tile, old and new, was pressure-washed and cleaned back to a sound, dust-free surface ready to hold a fresh coating.
- Two-coat roof repaint – The entire roof, including both the newer sections and the original tile roof over the main structure, was coated in two coats of a high-quality roof paint in a slate finish, chosen to match and unify the different roof sections into one consistent look.
SealAll Roof Contractors is an approved SealPro applicator, and this project used SealPro’s Stretch Seal ridge waterproofing system, matched to the tile profile and pitch of the roof.
The result: a sealed, uniform slate-grey roof
The finished roof reads as one cohesive surface rather than a patchwork of old and new sections. Every ridge is sealed and flexible, the previously cracked and slipped tiles are secure, and a fresh slate-grey coating has replaced the faded, uneven tone across the whole roof. The homeowner now has a weatherproofed roof with a clean, uniform finish and the manufacturer-backed protection of a proper waterproofing and coating system.
This is the standard of work homeowners in Vereeniging and across the Vaal Triangle can expect when a tile roof needs more than just a coat of paint — it needs the ridges, the tiles, and the surface all brought back to a sealed, sound condition together.

Metal Roof Waterproofing & Painting in Vereeniging
Location: Vereeniging, Gauteng
Service: IBR Metal Roof Maintenance, Waterproofing & Painting
Here’s a recent metal roof project that shows exactly the kind of damage a corrugated IBR sheeting roof builds up after years without proper maintenance. The roof in question was a large IBR steel installation that had never had a real service beyond the occasional touch-up coat of paint. The homeowner wanted the roof properly restored before small issues turned into structural ones, so the job covered the full roof area, including bargeboards, gutters, downpipes, and an attached carport.
The problem with the existing roof
Up close, the sheeting told the story of a roof well past due for attention. The original coating had faded and chalked, with sections of paint peeling away to bare, corroding metal along the ridges and screw lines. Rust had taken hold around several fixing points and joints, and the overlaps where the sheets meet were no longer sealed, leaving the roof vulnerable to leaks during heavy Highveld storms. With solar panels already mounted on the roof, any future leak repair would mean working around fixed obstacles, so getting ahead of the corrosion mattered even more.
The solution
SealAll Roof Contractors is an approved SealPro applicator, and the scope on this project combined SealPro’s waterproofing range with a dedicated roof paint system to cover both structural sealing and long-term surface protection:
- High-pressure wash and degrease the entire roof area to strip away years of grime, chalking paint, and loose debris, giving every subsequent layer a clean surface to bond to.
- Rust conversion and priming on all corroded sections, treating the metal before it could spread any further under the new coating.
- Waterproof the joints, overlaps, and screw lines using SealPro Flex, an elastic waterproof coating applied by hand across every vulnerable fixing point and sheet overlap on the roof.
- Prime the full roof surface ahead of topcoating, locking in adhesion for the paint system that followed.
- Apply two coats of Plascon NuRoof roof paint across the entire IBR sheeting, plus the bargeboards, gutters, and downpipes.
- Paint the carport roof and structure, bringing the attached carport in line with the newly restored main roof.
The crew worked the job over several visits, moving section by section across the roofline so each stage of waterproofing and coating could cure properly before the next layer went on.
The result
The roof now presents as a single, uniform charcoal-grey surface from ridge to eave, with every screw line and overlap sealed rather than just painted over. The peeling and rust that had built up around the fixing points and joints is gone, replaced by a roof system that’s properly waterproofed underneath the new coating. The carport now matches the main roof, and the solar installation sits on a roof that’s been fully protected around it rather than worked around. It’s the kind of maintenance job that adds years back onto a roof’s service life instead of just improving its appearance for a season.

Tile Roof Ridge Waterproofing & Repainting in Vereeniging
,Location: Vereeniging, Vaal Triangle
Service: Tile roof ridge repair, waterproofing and full roof painting
Cracked ridge caps and a UV-faded coating are one of the most common ways a tile roof starts to fail. Here’s a recent tile roof waterproofing and repainting project from the SealAll Roof Contractors team, carried out on a large concrete tile roof of roughly 352 square metres that had reached exactly that point.
The problem
Years of sun exposure had left the original roof coating oxidised, chalky and washed out, offering almost no protection against water, moss or further UV breakdown. Along the ridge line, the cement pointing had cracked, crumbled and pulled away in several places, leaving open gaps straight through to the substrate. A tile roof is only as watertight as its ridges — once the mortar starts letting go, it’s only a matter of time before wind-driven rain finds its way through the gaps and into the roof timbers below.
The SealAll solution
As an approved SealPro applicator, SealAll Roof Contractors doesn’t just paint over a tired roof — the full roof waterproofing system goes down in the correct sequence, so the repair actually holds:
- High-pressure clean. The entire tile roof was pressure-washed and scrubbed to strip dirt, moss and loose, chalking paint so the new coating could bond properly to sound tile.
- Rake out & fill. Every deteriorated ridge was raked out and all gaps, cavities and open bedding were filled with a flexible, purpose-made repair mortar.
- Prime. The repaired ridges were sealed with a deep-penetrating primer, so the waterproofing bonds properly to the porous tile and the cured filler.
- Ridge waterproofing. Each ridge was reinforced and sealed with a flexible, crack-bridging membrane system, creating a watertight cap that flexes with the roof instead of cracking again — the same approach as our weatherproof roof tiles work.
- Roof painting. The full roof was primed and finished with two coats of premium roof paint in a deep charcoal-grey, restoring an even, UV-resistant finish from ridge to eaves.
The result
The finished roof looks completely renewed — crisp, uniform ridges with no more open cracks, and a durable coating built to handle the Highveld’s heat, hail and summer storms. What was a tired, faded roof with failing ridges is now sealed, weatherproof and finished in a rich charcoal-grey that lifts the look of the whole property — the kind of roof coating and painting transformation homeowners across the Vaal Triangle can expect.
