IBR Metal Roof Waterproofing & Repaint in Rosebank

Location: Rosebank, Johannesburg
Service: IBR metal roof sheeting maintenance, rust treatment, screw-line waterproofing and full repaint

Metal roofs are common on both commercial buildings and modern homes across Johannesburg North, and they all face the same enemy: time. A recent case study on a large commercial IBR sheet roof shows exactly how a tired, rust-streaked metal roof can be brought back to a fully sealed, weather-tight finish — the same system Prime Seal Spray applies for property owners in Rosebank and the surrounding Johannesburg North suburbs.

The problem

Metal roofs fail from the fasteners outward. On the roof in this case study, years of sun, rain and thermal movement had chalked and dulled the original paint, and the curved IBR profiles showed clear rust streaking down the pans. Around every screw and every mounting bracket for the building’s solar array, the old sealing had perished, leaving hundreds of small entry points for water. Left untreated, that rust spreads under the coating and the screw penetrations become active leaks — exactly the kind of slow damage that stains ceilings and rots roof structure from above. The work also had to be carried out carefully around the live solar panels and their mounting brackets, which added an extra layer of care to the project.

The SealPro solution

Working off a scaffolding tower and boom access, with a full health and safety file in place, the applicator team followed a proven metal-roof system across the full roof area:

  1. High-pressure washed and degreased the entire roof to strip chalk, dirt and loose material back to a sound surface.
  2. Treated every rusted section with a rust converter to neutralise corrosion and stop it spreading.
  3. Primed the prepared steel with SealPro Purple Prime for a strong, uniform bond to the metal.
  4. Reinforced every screw line, sheet lap and bracket mount with Flex and StretchSeal, then sealed each fastener head with ScrewSeal.
  5. Applied two full coats of SealPro HydroSeal HF roof coating over the whole roof for a tough, waterproof, UV-stable finish.

The result

The tired, rust-streaked roof became a clean, uniform sheet from ridge to gutter. Every screw and bracket is sealed, the rust is arrested, and the whole surface carries a fresh flexible coating built to move with the steel through Highveld heat and summer storms. The building is protected, the rooftop solar array sits on a sound roof again, and the owner has a repaint that will hold for years rather than months.
