Article on cool roof failures in Phoenix?
This is going to be a super esoteric question for most people reading this but hopefully for not at least one person.
I’m trying to find an article describing the failure of the roofs of some upscale homes in Phoenix due to their use of either white roofs or radiant barriers but without handling ventilation properly. I read it within the past year but don’t know if it was written recently. I’m asking here as a last-ditch effort if only because y’all have a much higher likelihood of reading an article like this than most.
Okay, more details that I can remember. The builder built up the entire community with green building principles but after a very short amount of time (6 months to a year), new homeowners were complaining of visible condensation on the ceilings. When they investigated further, they found the roof decking to be often soaking wet with notable rot and mold already forming. The explanation given was that white roof reflected so much heat that the top of the deck was actually cooler than ambient air and so condensation gathered on the underside. This caused massive problems, maybe, because the ventilation was done completely wrong? My memory starts to fail at this part of the story and it’s the part that I want to remember the most.
Basically, I want to re-read what precisely went wrong and how they ultimately fixed it.
Anybody remember reading such an article?
