Reflective and protective coatings that seal, protect and extend; useful when a reserve fund cannot stretch to full replacement and the existing substrate is still sound.
When the existing roof is structurally intact but the surface is degraded, cracking or losing its weather resistance, a coating addresses the problem without the disruption and cost of a full strip and relay. A site assessment confirms whether the substrate is suitable, or whether a heavier intervention is needed first. Applied correctly to the right substrate, a coating adds a decade or more to a roof's working life.
White and light-pigmented reflective coatings reduce solar heat gain, which matters in Gauteng where UV exposure is high and occupied space below a flat concrete roof can become significantly hotter than it needs to be. The energy cost reduction from reduced air conditioning load is measurable. The coating also reduces thermal cycling stress on the substrate, extending its life further.
For metal roofs and sheeted surfaces exposed to UV and weather, a protective coating slows oxidation, seals minor gaps at laps and penetrations, and adds meaningful years to a roof that would otherwise need full replacement. Applied in the same mobilisation as other roof work, the additional cost of coating is marginal against the access that is already in place.
A coating applied over a dirty, chalky or poorly bonded surface fails early. Preparation, not the product, is what determines lifespan. This includes pressure washing, treating any biological growth, applying primer where the surface demands it, and addressing any penetration or joint failures before the coating goes down. Most early coating failures trace back to inadequate preparation, not product quality.
A roof coating is one of the more reserve-fund-friendly maintenance interventions available: it extends a roof's life by a decade or more at a fraction of the cost of a full re-roof, and the scope is easy to approve at a trustee meeting. Quotes are structured for trustee sign-off with a fixed price and a written scope, nothing added at invoice stage. A coating project is also routinely combined with waterproofing repairs or facade painting in the same mobilisation, so the building is not rigged twice and the combined access cost is shared across all the work. Sky Rig is SANS 10333 compliant; compliance documentation is ready before mobilisation to address OHSA Section 37 obligations before the first technician arrives on site.
Send us the details and we will assess the substrate, specify the right product, and quote you a system that will last, with documentation your trustees or managing agent can approve.
A roof coating is a liquid-applied or spray-applied product designed to protect, seal and reflect, applied over an existing sound substrate. Waterproofing usually refers to a membrane system, a more substantial intervention. Coatings are appropriate where the existing roof is structurally sound but degraded; waterproofing is more appropriate where there is active ingress or significant membrane failure.
