South African summers can be relentless — bright, hot days with temperatures soaring well into the 30s. While air conditioners work overtime indoors, the roof above you could be absorbing and radiating even more heat into your home. That’s where a reflective roof coating can make all the difference.
Prominent Neuklad Cool Roof is one of the most heat-reflective coatings in our professional range. With up to 30% heat reflectance, it helps your roof run cooler, reducing indoor temperatures and potentially easing the load on your cooling systems. Engineered for UV and water resistance and formulated with excellent flexibility, it’s built to withstand the harsh South African climate — from blazing sun to heavy summer storms.
Why Cool Roof Coatings Work
A reflective coating like Neuklad Cool Roof bounces back a portion of the sun’s infrared energy, reducing heat transfer into the building. This means your roof surface can be significantly cooler on a hot day, which:
– Improves indoor comfort in non-air-conditioned spaces.
– Reduces strain on air conditioning, lowering energy costs.
– Extends the roof’s lifespan by limiting thermal expansion and contraction.
Step-by-Step: From Cleaning to Coating
1. Inspection and Safety
Before you start, identify your roof type — cement tiles, fibre cement sheets, or galvanised steel. Plan for safe access and fall protection, and always work with a stable ladder or scaffolding. Inspect for cracks, broken tiles, loose fasteners, or leaks. Address these issues before coating to ensure a sound substrate.
2. Remove Organics and Contaminants
Clear algae, moss, and fungus thoroughly. For cement tiles, the Neuklad Cool Roof Technical Data Sheet (TDS) recommends Prominent Fungal Wash to eliminate spores and prevent regrowth. Rinse well and allow the surface to dry completely before proceeding.
3. Surface Prep and Repairs
– High-pressure wash or scrub to remove chalking, dust, and dirt.
– Fill cracks and repair defects to create a stable, uniform surface.
– Avoid painting in high humidity or cold conditions, as these can cause adhesion problems or uneven curing.
4. Priming (If Required)
Depending on your roof’s condition, priming may be essential. For example:
– Bare galvanised steel: Use a suitable metal primer to prevent corrosion.
– Porous cement surfaces: Apply a penetrating primer for optimal adhesion.
Check the TDS substrate preparation table for the correct system for your roof type.
5. Apply Neuklad Cool Roof
– Stir thoroughly before use.
– Apply the recommended number of coats, following recoat intervals and drying times.
– Work during cooler parts of the day and avoid painting onto sun-heated metal or damp surfaces.
How Much Do I Need?
Use our Roof Paint Calculator to estimate your roof’s paint requirement based on area and profile. Add an extra 5–10% as a safety margin for touch-ups and wastage.

With its 100% lead-free formula, anti-fungal properties, and wide substrate compatibility, it’s a true multi-surface performer.
SA Weather Tips for the Best Results
– Apply in moderate, dry conditions — ideally between 16°C and 28°C.
– Avoid painting in high humidity or just before dew formation.
– In summer, work in the early morning or late afternoon to prevent flash-drying.
– In winter, aim for late morning to mid-afternoon to take advantage of warmer conditions.
