This is the material list and cost estimate to build this bike shed. It came in a little higher than I first estimated but it is still a reasonable price at $215.00.

I didn’t include the price of felt paper because a 60 ft long roll of felt paper costs $25.00 and you will only need 8 ft. So there would be a lot of waste there. It will probably be ok as long as you don’t live in really wet weather or have a roof draining directly on it.
I have also not included the price of paint or caulk. You will need about 1/2 gallon for two good coats. Likely you have enough extra paint around the house you can use for free.
