Every roof type has its preparation, its primer and its pitfalls.
A steel deck is not treated like a bitumen membrane, and a five-year-old PVC membrane is not treated at all. These guides detail, roof type by roof type, what we check, how we prepare and what you can expect.

Cool roof on steel deck roofs: the complete 2026 guide (preparation, 4 layers, results)
Cool roof on steel deck: primer at 10 m²/L, 4-layer PrimaTherm® system, 95 % reflectance, up to −30 °C on the roof, pre-painted or galvanised. Free study.
Cool roof on bitumen roofs: application, blocking primer and measured results
Cool roof on bitumen membranes: blocking primer at 6 m²/L, 4 PrimaTherm® layers, −29 °C measured on a 5,900 m² project. Free study within 48 h.
Cool roof on waterproofing membranes: bitumen, EPDM, PVC — what can and cannot be done
Cool roof on waterproofing membranes: bitumen, EPDM, PVC over 10 years old with PH107PVC base. 95 % reflectance, SRI 120, −29 °C measured. Free study 48 h.
Cool roof on flat roofs: roof terraces, upstands, rooflights and flat-roofed houses
Cool roof on flat roofs and roof terraces: 95 % reflectance, SRI 120, up to −30 °C on the surface and −6 °C on top floors. Free study within 48 h.
Cool roof and solar panels: a cooler roof and modules that produce more
Cool roof and solar panels: a roof with 95 % reflectance lowers module temperature and feeds bifacial panels. The right order of works. Free study 48 h.
Cool roof on fibre cement roofs: asbestos-free only, and how we treat it
