Jack stressed the point that his panels are installed with a 'breathing space' between them and the roof shingles, to eliminate mildew and roof rot. He claimed his whole business depends on customers getting normal roof wear, not accelerated wear because of rot. I hired him because of a strong recommendation from a pool contractor whom I came to trust completely, I liked everything Jack said, and three years later everything works great. My calculations are that the solar system will be paid for by gas savings before the end of 2010.
