Oh by the way - the roof I have in mind is transparent (sun is precious in PDX), almost flat with just enough slope to shed water, will be hidden behind a tall beam facing the street. A friend (retired architect) built himself a carport using transparent corrugated plastic panels in this manner. They've held up fine to what snow loads we get here, and will be cheap to replace when weather and UV finally take their toll. However, I was thinking about glass. Anyone have an idea of the rough cost of 180 sq ft of glass, strong enough to hold 2 feet of wet snow with support every 24 inches, in panels that two people can manage? Bad idea?
