Hello, I tried the experiment a few years ago briefly and it did work. Some back of the envelope calculations show that it is cheaper and more energy effiecient. However there is a risk that lichens and or moss will thrive on a moist roof. So could be more trouble than it is worth.
- JoeAltmaier 7y agoThe roof is a fragile thing. Fool with it at your peril! Folks throw ideas around casually - "Put a garden up there! Use solar shingles! Spray water on it day and night!". Most will end in disaster. The roof is designed to hold itself up, keep out occasional rainstorms, and not blow away immediately in a storm. Nothing else. Pushing it way past its design parameters will end in grief.
- switch007 7y agoI'm rather confused by your reply and the reply to it. It rains a lot in England. Why would spraying it with water be any different from night upon night of heavy rain ?!
- ohiovr 7y agoI don't know actually. I had not thought of about places with constant rain. Anyway does it work? If you spray your roof on a super hot day does it feel any better indoors?
