Solar Reflective Roofing — White Roof Coating That Cools the Building
A dark roof in summer can run 40–50°C hotter than the air around it — and every degree ends up in the rooms below. A solar reflective roof coating turns that around: The GOAT in solar reflective white bounces solar radiation back before it becomes heat, cooling the roof surface, easing the load on air conditioning, and protecting the membrane itself from UV and thermal stress. And unlike traditional "solar reflective paints" that just decorate a tired felt roof, this is the roof — a seamless, cold-applied, ETA-certified liquid waterproofing membrane with a 25-year assessed working life.
Proven in Dubai: roof surface up to 30–45% cooler
We put the white GOAT where the sun fights hardest — a rooftop in Dubai, sprayed as one continuous membrane across the deck, upstands, plant bases and pipework. The result: surface temperatures running up to 30–45% cooler than a dark roof in the same sun — on this project the coated surface was measured 15°C cooler in the full heat of the day. In a climate where roofs bake at 80°C+ and air conditioning is the biggest bill in the building, that difference is felt in the top-floor rooms and on the electricity meter. If it performs in a Dubai summer, a UK heatwave is light work.
What a cool roof actually does
- Reflects solar radiation — a white surface reflects most of the sun's energy instead of absorbing it
- Cuts summer overheating — cooler roof deck, cooler rooms beneath, less air conditioning demand
- Extends membrane life — UV and daily thermal cycling are what age a roof; a reflective surface takes the sting out of both
- Waterproofs while it cools — this is a full liquid roofing membrane, not a paint-over: seamless, flexible, fully bonded
An honest word about reflective coatings
A reflective roof is not a substitute for insulation — if anyone tells you white paint replaces PIR, walk away. Its wins are specific and real: buildings that overheat in summer, hot climates, plant rooms and top floors that cook, warehouses with big uninsulated roof areas, and any membrane you want to last longer under UV. In winter the effect on heating is small, because the sun is low and weak when you'd want the gains. Design accordingly — we'll tell you straight whether your building is a good fit: ask our technical team.
Where it makes sense
Flat roofs over bedrooms and offices that overheat · plant rooms and server rooms · schools and care settings with summer overheating obligations · warehouses and industrial units chasing cooling costs · balconies and terraces in full sun · and export projects in hot climates — the Middle East, southern Europe and beyond, where our Dubai result speaks for itself.

The same trusted build-up as our Roofing & Balconies system: prime, then two coats of The GOAT in solar reflective white, thickness verified with a wet film gauge. Cold-applied — no torch, no hot works — over concrete, felt, asphalt or metal. Browse the liquid roofing membrane collection.
FAQs
How much cooler will my roof be?
Surface temperatures run up to 30–45% cooler than a dark roof in strong sun, depending on climate, the colour of the existing roof and exposure. On our Dubai project the coated surface was measured 15°C cooler in the full heat of the day.
Does it replace insulation?
No. It reduces solar heat gain and protects the membrane; insulation still does the insulating. The two work together.
Will it stay white?
Like any roof it will weather and collect dirt, which reduces reflectance over time — an occasional wash restores most of it. The waterproofing performance doesn't depend on the colour staying showroom-fresh.
Is it just for hot countries?
No — UK buildings that overheat in summer see real benefit, and the UV protection extends membrane life in any climate. But the hotter the sun, the bigger the win.
