Coop Roof Question

Why are you having plywood under it? run 2x4s lengthwise over the rafters about every two feet and fasten the tin to that. Take a look at my BYC page(s) I built a coop with tin on the roof and sides and have all the pics on there.

 

Tin can get hot in the summer and cold in the winter. I would insulate it, if it was mine.

 

What kind of tin are you talking about? Is it roofing tin (usually 26"wide formed sheets) or just sheets if tin? Roofing tin only needs a framework of 2x4's or such. The pre formed design gives it support lengthwise. By making 2x4 rafters 24" apart the tin lays on the rafters and needs only cross support between the rafters. Depending on where you live you could put insulation between the rafters if needed. Sheet tin would need to be on plywood for support and probably should have a moisture barrior between the tin and the wood as the tin could sweat in humid weather.

I would put tar paper between it.You want to keep the plywood as dry as you can so it doesn't rot out.

When You screw or nail it down make sure you use screws or nail that seal. I also put a bead of caulk where the tin over laps. We dont need any leaks.
