okay I'm making plans to make a kennel run this spring and figured now is the time to start my blueprints and pricing. Im stuck on the roof though, I'm in north west Pa so snow is the issue for me. Im looking for a cheap way to roof it that wont buckle under the snow or get blown away. Im ontop a hill and the wind gets nasty. Im still searching through threads but if anyone has an idea please let me know. BTY the kennel is 'attached' to my shed, so itll smack right up to a concrete builing. Thanks for any input.
