Roof Maintenance & Painting in Queenswood, Pretoria

Location: Queenswood, Pretoria
Service: Roof sheeting maintenance, waterproofing and painting

A large corrugated metal roof in Queenswood had reached the point where cosmetics and protection were both failing. The homeowner called Eco Seal for professional roof painting and maintenance — stripping back years of weathering, sealing the vulnerable joints and giving the roof a durable, freshly painted finish that would hold up to Pretoria’s sun and summer storms.

The problem

The roof sheeting had faded to a patchy, chalky orange and rust had taken hold across the panels. The worst damage was at the overlaps and screw lines, where old sealant had cracked and lifted and corrosion had eaten through in places, leaving open holes and blistered blue-green metal. Left as-is, those failed joints and rusted fixings are exactly where water finds its way in. A separate low-pitch slab section also needed attention, with the old waterproofing worn thin and no longer sealing reliably.

The Eco Seal solution

As an approved SealPro applicator, Eco Seal followed a full remedial system rather than simply painting over the problem:

1. High-pressure clean and degrease of the entire roof to strip chalking, dirt and loose material back to a sound surface.
2. Rust treatment — corroded sections were wire-cleaned and treated with a rust converter to stop the corrosion spreading.
3. Prime the sheeting with Purple Prime to lock down the substrate and give the coating system something to grip.
4. Seal the joints and screw lines — the weak points were reinforced with Flex and StretchSeal, and every fixing sealed with ScrewSeal so the overlaps and fasteners are fully watertight.
5. Waterproof the slab section using the ArmTec system — Penetrar primer, Flex and StretchSeal to the details, then HyperFlex with ArmTec reinforcing mesh and a HydroSeal HF top coat for a seamless membrane.
6. 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 now reads as a clean, uniform terracotta finish from ridge to eaves, with the joints and screw lines properly sealed underneath rather than just hidden. The slab section is protected by a continuous ArmTec membrane, and the whole roof is set up to shrug off Highveld weather for years to come. A cosmetic refresh and a genuine roof repairs and waterproofing upgrade in one project, the same approach we bring to waterproofing and roof painting across Pretoria East.
