Cool Roof
I live in sunny SoCal, where it was 100+ degrees today. Going to re-roof the house, and have been introduced to cool roof shingles by the builder (currently we have asphalt shingles). In this time of global warming, this sounds like a good idea.
In short, are these worthwhile? Do they work/make a measurable difference? Does the thermal reflectivity property last, or does it wear off over time? Almost everything I've read has been written by someone trying to sell the stuff.
We'll probably be in this house for the next 10 years, I'd guess.
