IBR Metal Roof Rust Treatment & Waterproofing in Johannesburg South
Location: Johannesburg South, Gauteng
Service: IBR Metal Roof Rust Treatment, Waterproofing & Painting
This case study looks at a residential property with a large IBR (corrugated metal) roof that had gone years without maintenance. What started out as a straightforward repaint turned into a full rust-treatment and waterproofing job once the crew got up on the roof and saw the true condition of the sheeting.
The problem with the roof
From ground level the roof looked tired but manageable. Up close it was a different story. Large sections of the IBR sheeting had corroded down to a deep orange-brown, with the protective coating gone in places and rust breaking through the metal along the ribs and overlaps. The screw fixings and joint lines were the worst-affected areas — exactly where water finds its way in first — and a few pipe penetrations and gutter-box junctions had failing old sealant letting moisture track behind the brickwork. Left untreated, active rust like this doesn’t stay cosmetic for long: it eats through the sheeting and turns into leaks and structural replacement costs.
The SealAll solution
SealAll Roof Contractors, an approved SealPro applicator, followed a proper rust-remediation sequence rather than just rolling paint over the problem:
- High-pressure wash – The full roof area was stripped of loose scale, chalking and surface contamination before any product touched the metal.
- Rust conversion – Every corroded section was treated to chemically neutralise the active rust so it couldn’t keep spreading under the new coating.
- Waterproofing the overlaps, joints and screw lines – The highest-risk points on any IBR roof were sealed with a reinforced waterproofing system, embedding fibre mesh into the coating over each screw head and rib joint for a durable, flexible seal.
- Priming – The prepared sections were primed to give the topcoat proper adhesion and long-term rust resistance.
- Two coats of a high-quality roof paint system – This gave the sheeting a uniform, weather-resistant finish that reflects heat and sheds water instead of trapping it.
- Painting the gutters, fascias and pipe penetrations to match – The roof-edge detailing was finished as one consistent system rather than a patched-together repair.
The result
The rusted sections of sheeting are now sealed and neutralised instead of actively corroding, every screw line and overlap on the roof has a waterproof barrier built into it, and the gutter and edge detailing are cleanly coated and weather-tight. It’s the difference between a roof that’s merely been painted over and one that’s actually been treated at the source of the problem — which is what keeps a maintenance repaint from needing to be redone again in two years.
Metal roofs across the greater Vaal region face the same combination of intense summer sun, hail and seasonal storms that caused this damage, which is why catching rust early with a proper conversion-and-waterproofing sequence is far cheaper than waiting for a full re-sheet.

Metal Roof Waterproofing & Painting in Sasolburg
Location: Sasolburg, Free State
Service: Metal Roof Rust Treatment, Waterproofing & Painting
Corrugated metal roofs take a beating from Highveld sun and summer hail, and once the paint layer starts to chalk and the joints start to lift, rust moves in fast. This case study walks through a typical metal roof rescue: a sheeting roof that had gone from faded and rusted to fully sealed, waterproofed and repainted.
The problem
The roof sheeting had faded to a patchy, chalky finish, with rust taking hold across several panels. The worst damage sat at the overlaps and screw lines, where old sealant had cracked and lifted and corrosion had eaten right through in places, leaving open holes and blistered metal. Left alone, those failed joints and rusted fixings are exactly where water finds its way into the roof structure. A low-pitch section of the roof also had old waterproofing that had worn thin and was no longer sealing reliably.
The solution
As an approved SealPro applicator, the crew followed a full remedial system rather than simply painting over the damage:
- High-pressure clean and degrease of the entire roof to strip chalking, dirt and loose material back to a sound surface.
- Rust treatment — corroded sections were wire-cleaned and treated with a rust converter to stop the corrosion spreading further.
- Prime the sheeting with a purpose-made metal primer to lock down the substrate and give the coating system something to grip.
- Seal the joints and screw lines — weak points were reinforced with a flexible sealant and stretch tape, and every fixing sealed so the overlaps and fasteners are fully watertight.
- Waterproof the low-pitch section with a reinforced membrane system — primer, flexible detailing at the joints, then a fibre-reinforced topcoat for a seamless, durable membrane.
- Paint the roof with two full coats of high-quality roof paint for a rich, even, UV-stable finish.
The result
The tired, rusted roof reads as a clean, uniform finish from ridge to eaves, with the joints and screw lines properly sealed underneath rather than just hidden. The low-pitch section is protected by a continuous waterproof membrane, and the whole roof is set up to handle Vaal-region weather for years to come. A cosmetic refresh and a genuine waterproofing upgrade in one project — the kind of job that keeps a metal roof watertight for another decade instead of just looking good for one season.
If your roof sheeting is showing the same warning signs — chalky paint, rust at the overlaps, sealant lifting at the screw lines — it’s worth having it inspected before the next heavy rain finds the gap.

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 & Painting in Vanderbijlpark
Location: Vanderbijlpark, Gauteng
Service: Tile Roof Ridge Repair, Waterproofing & Painting
Here’s a recent tile roof project from the SealAll Roof Contractors team that shows what a properly sequenced ridge repair and repaint can do for a roof nearing the end of its protective life. The concrete tile roof had reached the point where the ridge line was failing and the paint system underneath it had given up entirely.
The problem
Along the ridge line, the bedding cement holding the ridge caps in place had cracked and, in several spots, had gone missing altogether — leaving ridge caps loose and unsealed at the highest, most exposed point of the roof. That’s exactly where rain finds its way in first once the cement lets go. Across the tile field itself, the original protective top coat had failed under years of sun exposure: the colour had UV-faded and chalked out, patches of bare concrete tile were left exposed to the weather, and algae and fungal growth had taken hold across large sections, dulling the tiles and holding moisture against the surface.
The SealAll solution
As an approved SealPro applicator, SealAll Roof Contractors worked through the roof in two coordinated stages rather than just patching the visible damage:
- Ridge repair. All damaged ridge caps were raked out to remove loose, failing cement and refilled with fresh fibre cement to rebuild a solid, even substrate.
- Ridge priming and waterproofing. The repaired ridges were prepped and primed, then sealed with the SealPro Stretch Seal waterproofing system to keep the ridge line watertight and flexible under thermal movement.
- Full roof pressure wash. The entire tile roof was high-pressure washed by hand to strip off dirt, loose material and surface grime ahead of painting.
- Algae and fungal treatment. A dedicated algae cleaner was applied across the tiles to kill off fungal growth and stop it returning under the new coating.
- Two-coat roof paint system. The full roof was painted in two coats of premium roof paint in a slate finish, rebuilding UV protection and giving the roof a uniform, modern look.
The result
The roof went from a faded, algae-marked finish with an unsealed ridge line to a crisp, uniform slate-grey coat from ridge to eave. With the ridge caps rebuilt and waterproofed and a fresh two-coat paint system locking out UV and moisture, the roof is both weatherproofed at its most vulnerable point and refreshed cosmetically — the kind of result that adds years of protection from a single, well-sequenced project.

Tile Roof Waterproofing & Repaint in Alberton
Location: Alberton, Gauteng
Service: Tile Roof Preparation, Waterproofing & Painting
A weathered tile roof does more than let a home down at the kerb. Once the original glaze and colour have faded, the tiles start to soak up rain, grow moss and lichen, and lose the protective surface that keeps water moving away from the substrate. Here’s a recent tile roof project from the SealAll Roof Contractors team, tackled on a concrete tile roof of roughly 321 square metres that had reached exactly that point.
The problem
Years of Highveld sun and rain had left the concrete tiles chalky, patchy and discoloured. The colour had washed out to a dull, uneven green-grey, and the ridge caps had weathered along the mortar joints, the exact places where wind-driven rain likes to find a way in. Left untreated, a roof in this condition keeps deteriorating: porous tiles hold moisture, the ageing surface breaks down further, and small ridge gaps grow into leaks.
The SealAll solution
As an approved SealPro applicator, SealAll Roof Contractors followed a proper preparation and coating sequence rather than simply rolling paint over dirty tiles:
- Deep clean and prep. The entire roof was high-pressure washed and scrubbed by hand where needed, stripping away dirt, moss, chalking and loose material so the new coating could bond to sound tile.
- Ridge and profile attention. The ridge line and tile profile were assessed and prepared, with the ridge caps sealed so the weakest points of the roof were locked down before painting began.
- First colour coat. With the surface clean, dry and sound, the first full coat of high-quality roof paint was applied across the full tiled area, working with the tile profile and pitch of the roof.
- Second colour coat. A second coat followed to build an even, durable film, deepen the colour and give the tiles a consistent, protective finish from ridge to eaves.
The result
The transformation is hard to miss. The tired, faded roof became a rich, uniform green that reads crisp and clean under a clear Highveld sky. The finish sheds water instead of soaking it up, the ridges are sealed and tidy, and the whole home looks years younger. It’s a roof that not only looks the part but is far better protected against the next round of sun and rain — the kind of result homeowners across the Vaal can expect from a properly specced tile roof waterproofing job.
SealAll Roof Contractors is an approved SealPro applicator serving Vereeniging, Alberton and the greater Vaal region. If your tile roof is chalky, faded or showing signs of wear at the ridges, it’s worth getting it inspected before small problems turn into leaks.
