Hey TOH folks,
The roof on my 1.5 story, side-gabled 1920ish bungalow in central NC is about ready for an update and I'm trying to find solutions that:

1) are compatible with the historic character of the house, and
2) can take advantage of the southerly direction of the front of the house for solar; and/or
3) can help with tremendous heat gain experienced upstairs in the summer

I've found some info on solar shingles, but haven't seen any that would seem to visually disappear. Not sure if anyone is making thin film solar applications for roofs yet that might be incorporated into a metal standing seam roof (or maybe tin shingles style) or not, but that could be ideal. Just trying to figure out what the options are in order to be able to make a legitimate estimate of costs & benefits rather than start a thread on virtues of pv. In terms of the heat gain, I've tried a gable vent fan without much success, but additional ventilation/insulation/uv barrier might also be considerations and part of the ultimate solution.

Please weigh in with any suggestions along these lines or others I may be missing. Thanks.
