Metal Roof Waterproofing & Painting in Bryanston
Location: Bryanston, Johannesburg
Service: IBR metal roof maintenance, waterproofing and painting
Corroded IBR roof sheeting is one of the most common calls Prime Seal Spray gets from homeowners and body corporates across Johannesburg North. Years of sun, summer storms and thermal movement quietly eat away at a metal roof’s protective coating, and by the time rust stains start showing on the ceiling below, the sheeting underneath is usually already compromised. The case study below shows the full strip-clean, rust-treat, waterproof and repaint process Prime Seal Spray uses to bring a failing metal roof back to a watertight, factory-fresh finish.
The problem: a rusting, leaking IBR roof
An on-site inspection is always the starting point. On roofs like this, the IBR sheeting is typically heavily weathered, with rust blooming along the overlaps and around every fastener head. Debris collects in the box gutters and valleys, holding moisture against the steel and accelerating corrosion from underneath. Seams and screw lines open up over time, letting water track under the sheets and into the ceiling and structure below. Left untreated, this kind of deterioration only spreads — turning what should be routine maintenance into a full, costly sheet replacement.
The Prime Seal Spray solution: a SealPro metal roof system
As an approved SealPro applicator, Prime Seal Spray specifies a coating system built specifically for corroded IBR sheeting, working methodically across the entire roof area:
- High-pressure clean and degrease — the full roof is washed down to strip loose rust, dirt and old chalking, and every gutter and valley is cleared of debris.
- Rust treatment and priming — corroded sections are treated with a rust converter, then sealed with SealPro Purple Prime to lock down the metal and create a sound bonding surface.
- Waterproof the weak points — all overlaps, joints and screw lines are reinforced with Flex and StretchSeal, with ScrewSeal patches applied over every fastener head to seal each penetration.
- HydroSeal HF membrane — a flexible waterproof top layer is applied to bridge movement in the sheeting and lock out water for the long term.
- Two coats of premium roof paint — the roof is finished in two coats of high-quality roof coating for a uniform, UV-stable colour and a clean, protected surface.
The result: a watertight, refreshed roof
The transformation speaks for itself. Rust-stained, leaking sheeting becomes a crisp, uniform roof — fully sealed at every lap, screw and seam, and built to handle the next round of Highveld summer storms. Homeowners get a roof that sheds water reliably, looks brand new, and has years of extended service life without the cost of full sheet replacement.
