Flat patio roofing materials compared on heat performance, noise in rain, natural light, clear span and ceiling finish
Material	Heat performance	Noise in rain	Natural light	Clear span	Ceiling finish
Colorbond Flat Patios	No insulation, radiates heat down through the afternoon	Loud, drums in a downpour	None, opaque sheet	Short, needs purlins every 1.2 to 2.4 m	Purlins visible unless you add a lining
Polycarbonate Flat Patios	Clear passes heat freely, tints cut it and dim the space	Loudest of the four	Around 10 to 90 per cent, set by the tint	Shortest, supports at 600 to 900 mm	Translucent sheet, supports visible through it
SolarSpan Flat Patios	Insulated core, roughly R1.4 at 50 mm to R2.8 at 100 mm	Noticeably quieter than single-skin steel	None, opaque panel	Around 3 to 6 m clear, no purlins	Finished flat or lightly grooved underside
Cooldek Flat Patios	Insulated core, roughly R1.4 at 50 mm to R2.8 at 100 mm	Noticeably quieter than single-skin steel	None, opaque panel	Around 3 to 6 m clear, no purlins	Finished smooth or lightly ribbed underside
