Yup over sheeting , under siding, what about when you are cheeting and only using one.
Remove the window, cut sheeting above window about 1/2 inch and slide flashing up between sheeting and frame.
Install window and add trim around, if window has nailing flange, remove to part of flange. http://joneakes.com/jons-fixit-datab...dows-and-doors
I'm glad it's a shed in a place that gets no weather. I will rework it tomorrow but it is still not ideal.
Anyway progress is still moving forward. Wallet is getting lighter every day. Next is to finish that short block wall. Probably going to stucco it to match the house. Was gonna do something fancy but I just want it done.
