Baz, sorry for the hijack of your very informative roofing thread.
So much knowledge and help available here.
I'll try to keep my discussions of other building issues brief.

VincentVega, there are some framing issues in both the front and back walls to be sorted around the big openings for the doors. The end walls appear to be well framed and sound.

Paul, that's exactly the plan I have for the siding. Did you wrap the existing siding with tyvek befor installing the metal siding?

Chris, that sounds like a very effective roof assembly you did.
I'm wondering if the standing seam clips can be installed directly on top of a sheet foam insulation layer with a membrain on top of the foam? Or if a top layer of ply on top of the foam is called for?

Dad911, my goal is primarily to get a well insulating, dry, long lived, wind resistant roof at the best cost.
Painted ply over new rafters will be just fine for interior decore.

One of the reasons I've made so little progress on this building over this last year is that I'm saving resorces for the installation of infrastructure to the planned rental RV sites, once the permitting process is done.
Once they are generating income, Ill be better able to chip away at the rebuilding of the shop. But in the mean time I would like to get the roof done and keep the interior dry.
So far the permitting process has been glacially slow. Just getting the driveway easement sorted with the state has taken over 7 months, and that had to be completed before the county will consider the zoning change for the property.
The delays have given me time on the property to better refine the development details. But enough allready.

Did I say I'd keep it brief? Sorry Baz.

Cheers Richard
