Just an update to the thread...
We're sorta moved in - at least we're living in the new place.
We're 2" above the amount of rain we should have by this time of year. The driveway turned to mud about 4 weeks ago. I'm parking at the top and driving the ATV up and down the driveway to minimize the damage. I guess I'll be doing some excavation if it ever stops raining.
That's made getting any sort of sheet goods down to the garage a little difficult, short of me marching them down by hand one at a time. I've been putting it off, but the homeowner insurance gave us 60 days and that's the end of this month.
I used Google Earth to measure the driveway. It's 750' from the road to the front of the garage and about 100' elevation drop. Google's reasonably accurate horizontally, but sometimes their elevation leaves a bit to be desired.
My wife wants a range installed (the cooking kind), so I've managed to rig up the ATV with a hitch that will fit my HF trailer to get the stove down. I can use that to shuttle OSB/plywood/etc down.
So, the way the PO built the pole barn is with poles, obviously. The poles are basically 8' apart, a mix of 6x6, 6x4 and 4x4. He made the corner poles fit the building footprint of 32x48, but then he used outside girts making the whole building 32'3" x 48'3" so whole sheets don't fill the space. At the top of the poles, there are two 2x12 boards nailed on either side along the long wall supporting the 2nd floor joists. Not how I would have done it, but that's what I got to work with. The girts also leave an odd gap around the garage doors (never really finished) that has to be covered.
So, the plan is to replace the outside girts on the lower part of the walls with bookshelf/commercial girts and spacer boards. That will make it possible to use full sheets of OSB and will close the gap around the garage doors. I'm going to use PT plywood on the bottom 2' and then OSB on the rest with the girts spaced to intersect with the gaps in the sheet wood (unlike what the PO did) Plan on using metal roofing/siding on top of the PT plywood on the lower portion as soon as I find a good source and then use the vinyl siding on the rest. When I hit the level of the beams holding up the 2nd floor, I'm just going to continue that lip around the side walls and then continue up the sides. Seems the easiest way to go and it will give an interesting detail I suppose.
Leaving off windows on the 1st floor for security even though we're in the middle of nowhere. It also give more wall space. I will probably put some on the 2nd floor since I already have them and it's darker up there with no doors.
I can get metal roofing at Lowes although they seem pretty pricey, but most other places around here aren't open on the weekends or evenings which limits my ability to use them. I don't need all that much so I may go ahead and use them. I'm going to use housewrap under the metal and siding, although I'm still debating between Lowe's house brand and Tyvek. I think Tyvek's better, but it's just an unheated garage and either's got to be better than nothing. Thought about using felt paper, but the wrap's a lot easier once I have to get up on a ladder with it.
We've got rain constantly until Saturday afternoon and the range is a priority. I hope to at least get some PT plywood and maybe the metal siding/roofing down to the site and maybe start cutting/installing it this weekend. I have to go bottom up with all of it, and it seems easiest to work my way up in sections - remove/install sheeting/install housewrap/install siding then get all the ladders set and do the next 4' or 8' taking down the old and putting up the new.
