Most roof leaks at wall junctions, skylights, and chimneys are flashing failures, not tile failures. We see this in homes across Gauteng, from older suburbs around Johannesburg’s Constitution Hill to newer developments near Centurion Mall, where silicone has been applied over a failed flashing and water is still getting in every rain. We fix flashings properly. Call 081 016 3479.
When You Need Flashings Waterproofing
Flashings need attention when you see water staining on internal walls just below where the roof meets a vertical surface, a parapet wall, chimney, gable end, or the wall of a room above. Water appears during rain and may not show immediately. Step flashings, apron flashings, soakers, and lead or fibre cement flashings all deteriorate over time. Silicone sealant applied over failed lead flashings works briefly but cracks within a season, it’s a patch, not a fix.
Our Flashings Waterproofing Process
We inspect all flashings, noting areas of corrosion, lifting, cracking, or failed sealant. Lead flashings that have cracked or lifted at the upstand are repaired or replaced with new lead. Fibre cement flashings are replaced where deteriorated. Where re-flashing isn’t possible, we apply a compatible flexible flashing tape system with proper primer and sealed termination edges. Counter-flashings that have lifted from chase cuts in brickwork are re-fixed and pointed. We leave nothing exposed that water can get behind.
