We built our coop this summer, but didn't put roofing materials on. We have been doing our house roof, and have a bunch of fancy 30 year, 100 mph shingles left over, so with help from my dh, I roofed my coop. When I was building the coop (well, when I was HELPING dh build the coop....) i nearly cut my thumb off with a sawsall, so using a nail gun made me a bit nervous. But, I did it without a single cut, scrape or bruise. Go me! It's no Taj Mahal, but I'm pleased.
