By selecting the right finish it provides you with the ability to reflect the suns rays measured as TSR before they convert to heat and then to emmit the ones the do convert to heat measured as TE. Enegry star has rating requirements. SThere are systems that have venting under the covering which then ventilate out any heat that does pass through. USDOE tests on these systems have shown a 70% reduction in heat transfer to the ceiling when compared to asphalt shingles.
