Some colors fade much faster than others. Some brands of paint flake and fade much faster than others. White galvanized steel on the roof reflects much more heat than do dark shingles. White galvanized steel can save a lot of money in cooling costs. Of course, it’s not allowed here.
“ A white, galvanized metal roof should save a customer who lives in an average-size 1,770 square foot home approximately $128 or 23 percent annually in cooling costs, compared with a dark gray shingle roof on the same home. For the same size home, white, S-shaped cement tile produces the second-best savings of $110 or 20 percent of annual cooling costs followed by white, flat cement calculated at $96 per year for a 17 percent savings compared to the dark gray shingles. White shingled roofs trim $24, or about four percent off the annual cooling bill, while terra cotta S-shaped cement tiles net a modest $15, or three percent compared to dark gray shingles.”
