Although I feel metal roofing is best and is effectively a once-in-a-lifetime event, good quality asphalt roofing is a twice-in-a-lifetime event at half the price, and I like the quiet.
I installed the only no-extra-cost Energy Star non-white roof detailed
IN THIS THREAD. There may be other no/low cost options available now, but I am pleased since I couldn't have a metal roof and it made a huge difference in the heat.
I would assume that except for standing-seam metal roofs, an asphalt roof is easiest and most flexible for mounting solar collectors. Anyone have comparative mounting experience on different roof types?
