We also had another case where the HOA didn't allow anything but shake shingles. Timberline asphalt shingles had just come out and a homeowner used them instead of shakes. The HOA sued and the homeowner took it up the ladder through the courts claiming TImberlines didn't subtract from the looks and asphalt had a much better safety record than shakes. (very true!) The homeowner eventually won and kept his Timberlines, after which most HOA's around here allowed Timberline or similar as an acceptable replacement for shake shingles.
HOA's can be a PITA if you get some anal retentive idiots running them.
