If You’ve Got a Dark Roof, You’re Spending Almost $700 Extra a Year to Keep Your House Cool: Cool roofs markedly reduce how much energy you need to cool a house. When used at scale, they lower the air temperatures of entire suburbs #GlobalCarbonFeeAndDividendPetition

  1. Help me understand this. I get that dark roofs capture and hold in more heat.

    But don’t most geographies use more energy for heating than cooling? My Colorado home uses roughly 5x the energy for heating than I do for cooling. I’d assume that the dark roof helps add heat in the winter, but I’d be curious to hear from someone that understands the topic.

  2. Yeah as a northerner I could see this being way more beneficial for increasing albedo, especially as we lose more snow and ice, than balancing individual homes energy usage, except in hotter climates.

  3. I have a darkish roof with solar panels on it…so likely nets out ok because in the winter I get some heat.
