What are the compelling reasons for installing a metal roof?
Metal vs. asphalt shingles: Are the reflective shingles that qualify for the energy star rebate a good value? I wonder about the long term reflectivity. Is there any information about the copper additive that is supposed to retard mildew washing off - especially given the acid rain in the east and the fact that they only warrant the shingles against mildew for a limited time? If I go with metal, do the clear coats on the galavalume last as long as the paint finishes?
