I have a flat, foam roof, painted white. It really does work to keep the house cool, although the flat roof geometry would be problematic in climates with more precipitation.
I suspect roof paint will be much less important in coming decades as solar panels proliferate, however.
- john_yaya 5y agoVery similar thing here, I live in the Bay Area and have a flat, bright white roof. On an 85 degree summer day, it’s a wave of cool comfort to walk through the front door, and I pay nothing for it.
- clairity 5y agoi live in an apartment building in LA with a vented attic and a flow-through design, as the building was built before air conditioners became popular. it’s cooler than ambient by a few degrees (haven’t rigorously measured it though) even without a white roof.
