Metal Roof Waterproofing in Parkhurst
Location: Parkhurst, Johannesburg
Service: Metal roof sheeting waterproofing and screw replacement
Steel-sheeting roofs are common on homes, warehouses and commercial buildings across Johannesburg North, and they tend to fail in the same predictable places: the screw lines and the sheet joints. On a recent case study job, a steel-sheeting roof was showing water stains inside the building, and an inspection traced the damage straight up to the fasteners and seams holding the sheeting together.
The problem: failed screws and cracked joint seals
Metal roofs live and die by their fasteners and their joints. Years of sun, wind and summer storms had taken their toll: dozens of roofing screws had worked loose or corroded, breaking the seal at every fixing point. Along the sheet laps and ridge junctions, the old sealant had cracked, lifted and streaked with weathering, leaving open channels for rainwater to track straight into the building below. Corner flashings had broken away entirely, and every one of those gaps was a potential leak.
The solution: a SealPro metal-roof system
As an approved SealPro applicator, the team treated the roof as a complete system rather than patching isolated spots. Loose and failed roof screws were replaced, and the waterproofing was rebuilt across every joint and screw line using the SealPro metal-roof process:
- Purple Prime was applied to prepare and key the steel surface for maximum adhesion.
- Flex reinforced with StretchSeal was worked into every screw line, sheet lap and ridge junction to bridge movement and seal the seams.
- ScrewSeal patches were placed over individual fastener points and problem areas for a durable, watertight cap.
- HydroSeal HF was applied as the tough, flexible top membrane, locking the whole system together against water ingress.
Full supervision and quality control ran throughout the job, so every fixing and seam was checked before sign-off.
The result: a sealed, watertight roof
A neat membrane now runs the full length of every screw line and joint, the loose screws are replaced and sealed, and the flashings are watertight again. Instead of a patchwork of cracked seals and rust spots, the roof has a uniform, professionally waterproofed sheeting system built to shed heavy Highveld rain for seasons to come.
