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:

1. 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.
2. Rust conversion and priming on all corroded sections, treating the metal before it could spread any further under the new coating.
3. 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.
4. Prime the full roof surface ahead of topcoating, locking in adhesion for the paint system that followed.
5. Apply two coats of Plascon NuRoof roof paint across the entire IBR sheeting, plus the bargeboards, gutters, and downpipes.
6. 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.
