I am in Seattle but grew up elsewhere, in the country, where every second house had a pile of rusting corrugated metal roofing behind it. I have designed and built a coop with this in mind for the roof - all it needs is a door and a roof. It's too late to substitute asphalt shingles (the slope is too low to use them), and I've blown my budget on upgrades to the coop (hubby is an architect, some of my ideas just didn't fly...). Is there anyone in the Seattle area that has any ideas about how to find used roofing for a sloped-roof coop that will be waterproof and appease our very opinionated neighbors? I've tried the Re-store and Second Use, Craig's List, even regional classified ads. No-one has the stuff (metal or acrylic). Here's the coop, sans roof: The babies are getting big and I need to get them into this soon! Thanks all.
