I just bought a great traditional wooden dog house on Craigslist ($35!). The roof is made of overlapping planks, which looks nice, but a couple are starting to split and I know if I can break them open a raccoon certainly could. I'm thinking of removing the roof (even though it looks nice!) and replacing it with hinged plywood so I can get into the house to clean it and collect eggs. Is it possible to have a hinged roof that's still waterproof and/or shingled? I'd love to see photos of anyone's hinged roof......Thanks!
