IBR Metal Roof Waterproofing & Repaint in Alberton
Location: Alberton, Gauteng
Service: IBR Metal Roof Waterproofing & Painting
Steel IBR roofs are tough, but the coating and the fixings are where they age fastest. In this case study, an IBR sheeted roof had reached the end of its original coating life after years of sun, rain and thermal movement. The sheeting had weathered badly, rust was creeping in along the overlaps, and the screw lines had become the weak points where water could track through. The brief was simple: bring the roof back to a fully sealed, watertight, good-looking condition without a full replacement.
The problem
IBR profile sheeting is durable, but it lives or dies on its coating and its fixings. On this roof the paint had faded and chalked, exposing bare metal that was already showing rust bloom along the raised ribs and side laps. The self-tapping screws had loosened slightly over time, and the old sealant washers had perished, so every screw line was a potential leak path. Left untreated, that corrosion spreads under the coating and the joints keep opening up — a proper strip-back, treatment and re-seal was the only lasting fix.
The solution
As an approved SealPro applicator, the crew followed a full metal-roof remediation system rather than simply repainting over the problem:
- Access and prep. Any adjacent tiled sections were carefully lifted and stacked so the full IBR area could be worked, then the entire roof was high-pressure washed and degreased back to a sound surface.
- Rust treatment. All rusted sections were mechanically cleaned, treated with a rust converter and primed with Purple Prime to lock down the metal and give the coating system a stable base.
- Seal the weak points. Overlaps, joints and every screw line were reinforced with Flex and StretchSeal, and the fixings sealed with ScrewSeal, closing off the paths where water had been getting in.
- Waterproof membrane. HydroSeal HF was applied over the prepared and sealed sheeting to form a continuous, flexible waterproof layer that moves with the roof.
- Finishing coats. Two coats of high-quality roof paint were applied for a uniform, UV-stable finish, and the gutters were cleaned and waterproofed to complete the drainage.
The result
The roof now reads as a single clean, uniform plane — sealed overlaps, protected screw lines and a fresh, durable coating from ridge to eaves. The rust has been stopped and encapsulated, the leak paths are closed, and any reinstated sections tie the roofscape back together neatly. The outcome is a watertight, low-maintenance IBR roof built to give many more years of reliable service before it needs attention again.

Commercial Roof Slab Waterproofing in Alberton
Location: Alberton, Gauteng
Service: Commercial Roof Slab Waterproofing with Trafficable Top Coat
A commercial flat roof slab at a shopping centre needed a complete waterproofing overhaul before the exposed concrete could keep doing its job of protecting the units and trading floor below. Across roughly 190 square metres of roof deck, the bare slab and the crowded rooftop plant area around the HVAC units had no reliable waterproofing membrane in place, leaving the whole roof vulnerable to seasonal downpours. SealAll Roof Contractors was brought in to prep, waterproof and finish the slab as a fully trafficable roof.
The problem: an exposed, untreated concrete deck
On inspection, the roof slab was raw, unsealed concrete. Sections around the rooftop plant room, water tanks and air handling units were especially exposed, with no membrane protecting the surface from ponding water, foot traffic or UV degradation.
The main issues on site:
- Bare, porous concrete across the full slab with no waterproofing system installed
- Heavy rooftop plant congestion (HVAC units, water tanks, ducting) making the deck difficult to access and prep around
- A trafficable surface required, since technicians need regular access to the plant equipment for maintenance
Left as-is, an unwaterproofed slab like this was only a matter of time away from water ingress into the ceilings and plant room below.
The solution: the ArmTec system with a trafficable top coat
As an approved SealPro applicator, SealAll Roof Contractors specified the ArmTec waterproofing system finished with a trafficable top coat, built for exactly this kind of high-traffic commercial roof deck. Our crew worked through the following steps on site:
- Cleared the roof and carefully worked around the HVAC units, ducting and water tanks to access the full slab.
- Prepped and primed the substrate across the entire 190m² area, giving the concrete a sound, clean base to bond to.
- Applied the ArmTec waterproofing system as a continuous membrane over the full slab, sealing every joint, upstand and detail around the rooftop plant.
- Finished the surface with a trafficable top coat, giving the roof a durable, textured, walkable finish that can handle regular maintenance foot traffic.
The result: a fully waterproofed, trafficable roof deck
The slab now carries a single, continuous ArmTec waterproofing system finished in a durable trafficable top coat. Technicians can walk the roof safely to service the plant equipment, and the centre no longer has an exposed concrete deck sitting unprotected through the rainy season. The finished surface is watertight, textured for grip, and built to handle years of both weather and foot traffic.

Metal Roof Waterproofing & Painting in Alberton
Location: Alberton, Gauteng
Service: Metal Roof (IBR) Waterproofing & Painting
This case study looks at a large IBR sheeting roof that had done its job for years but was starting to show its age. Rust was creeping in around the screw fixings and the original coating had faded and chalked in the sun. The owner needed the roof brought back to a clean, protected, weathertight finish before small problems turned into costly ones — exactly the kind of job SealAll Roof Contractors handles for homes and complexes across the Vaal region.
The problem with the existing roof
Up close, the trouble spots were easy to find. Dozens of screw fixings across the roof had started to rust, with orange staining bleeding down the sheeting on either side of each point. Left alone, rusting screws don’t stay a cosmetic issue — moisture works its way past the washer, fixings lose their grip, and small leaks start finding their way into the roof structure. The original coating was also tired: sun-bleached, thin in places, and no longer giving the metal sheeting the protection it needed against South African heat and summer storms.
The SealPro solution
Working as an approved SealPro applicator, the team carried out a full maintenance and repaint programme across the roof:
- Wash and degrease the entire roof area to strip off dirt, chalking, and surface contaminants so the new system could bond properly.
- Treat every rusted section with a rust converter, neutralising corrosion at the screw lines and sheet joints before it could spread further.
- Prime the treated sections to lock down the converted rust and give the topcoat a stable, uniform base.
- Apply two full coats of a high-quality roof paint system, rolled and brushed by hand across the full profile of the sheeting for even, durable coverage.
- Reinforce the screw line, sealing each fixing point with FLEX and StretchSeal patches for an extra layer of waterproofing where the roof is most vulnerable to moisture ingress.
The team worked the roof section by section over several days, keeping full coverage consistent across every panel and ridge line.
The result
The roof now carries a fresh, even topcoat from ridge to eave, with every screw line sealed and protected against future rust. What was a patchy, corrosion-prone surface is now a uniformly coated, weather-ready roof built to hold up to years of sun and rain.
If your IBR sheeting, corrugated, or metal roof is showing rust at the screws or a coating that’s past its best, the same system can bring it back to a sealed, protected finish. SealAll Roof Contractors is an approved SealPro applicator serving Vereeniging, Alberton and the greater Vaal region.

Tile Roof Ridge & Valley Waterproofing in Alberton
Location: Alberton, Gauteng
Service: Tile Roof Ridge & Valley Waterproofing
A tiled roof on a residential home was showing its age at exactly the points where roofs fail first — the ridges and the valleys. SealAll Roof Contractors was called in to rake out, refill, waterproof and colour-match 45 linear metres of cracked ridge caps, clear and reseal the valley sections, and waterproof the flashings and screw lines on an adjoining sheeted roof area.
The problem
On inspection, the ridge cement running along the top of the tiled roof was cracked and missing in multiple sections, leaving open joints along almost the entire ridge line. Gaps like this are one of the most common entry points for water on a tiled roof — rain tracks straight along the ridge and into the roof structure below instead of running off. The valley sections, where two roof planes meet, were blocked with debris and had loose tiles, another classic weak point that lets water pool and force its way under the tile courses. Nearby, the flashings and screw lines on a section of sheeted roofing also needed attention, with exposed screw heads and open flashing joints creating further paths for leaks.
The solution
SealAll Roof Contractors, an approved SealPro applicator, worked through the full ridge line, the valleys and the sheeted section systematically:
- Rake out and re-fill the ridges — All 45 linear metres of cracked ridge cement were raked out back to a sound base and re-filled with fresh fibre cement to close the open joints.
- Prime the substrate — Each repaired ridge section was primed so the waterproofing membrane would bond correctly and last.
- Waterproof with the SealPro Stretch Seal system — The ridges were reinforced and sealed using SealPro’s Stretch Seal ridge system, a flexible membrane that moves with the roof under thermal expansion instead of cracking again.
- Colour code the ridges — Once sealed, the ridge caps were colour coded to blend back in with the surrounding roof tiles for a neat, uniform finish.
- Clear and reseal the valleys — The blocked valley sections were cleared of debris, filled with fibre cement where needed, primed and waterproofed with the same Stretch Seal system to restore free water flow off the roof.
- Seal the flashings and screw lines — On the adjoining sheeted roof section, all exposed flashing joints and screw lines were waterproofed to shut down the secondary leak points, with the gutter-line sheeting trimmed and flutes closed for a clean, weathertight edge.
The result
The ridges and valleys that were once cracked and open are now fully sealed, reinforced and colour-matched into the roof, closing off the paths where water was getting in. With the flashings and screw lines on the sheeted section also waterproofed, the homeowner now has a roof that’s protected at every joint — not just patched at the surface — giving lasting peace of mind ahead of the next rainy season.
This kind of ridge and valley failure shows up on tiled roofs across the region, and it’s exactly what the SealPro Stretch Seal system is built to solve permanently rather than patch temporarily.

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.
