bubblegoose, you are correct in your statement.The only reason that you do not see more white roofs is there is no demand for them. At least that was what I was told.

BG. You are so, so right.

Check out www.supertherm.net & www.icc-astec.com

I have sprayed two roofs with Astec products, and temps on the underside of the metal dropped by over 30 degrees on one roof, and 66 on the other (different times of year).

My own, unfinished website is www.energysaviours.com on the "About us" page you can see the difference we made to the metal roof of the "Steamatic" storage building in Beaumont TX. The owner is ecstatic with the results.

I personally love this stuff.

Hey bubblegoose, you never see any white roofs? or you never see any electricity savings?

Some of this depends on how much insulation you have and how much ventilation the attic has but thelighter colours do benefit you. White has become passe' partly because of the mildew problem. Stains show and don't look particularly nice.

Plenty of white roofs in my region. Most shingle manufacturers make a 'white' shingle that has white stones.

And yes they keep attics cooler.

Personal taste in roofing overcomes practicality in energy savings most often, however.
