re: #190 Decatur Deb

The last time I shingled the house, I put on an Energy-Star rated “Shasta White”. It’s just a more reflective aggregate in a conventional asphalt shingle—seems to reflect perhaps 70% of visible. The effect, in conjunction with superinsulation of the attic, was pronounced. In time, however, erosion of the ceramic granules and bioaction reduces the effectiveness.

previous owners painted a coating of reflective white substance over shingles

all hurricane wilma had to do was start at one corner and she sheared off one big shingle
