I’ve frequented this site for the last year – it’s on my daily rotation, specifically the Projects page. Love the woodworking showcased there.
I’ve been woodworking for ~1 year in a decades old building that needs some repairs. I’ve not done anything of this scale before, so I wanted to get my ducks in a row before I proceed.
I have a 36’ x 16’ building on a concrete slab that is as simple as it can get: 4 walls and a roof. It is uninsulated and up until 3-4 months ago, would flood with any significant down pour. The roof (as you can tell from the pics) is sagging in the middle and as such has moved the side walls out of plumb. This building is at least 20 years old.
As you can see there are no joists for the rafters. The walls are 2×4 construction (16 in on center) as are the rafters (24 in on center).
My wife and I plan on building a new shop/art studio several years down the road partially over this location. I live in Arkansas, so our summers can be brutal. So I’m faced with either sweating it out, taking a “vacation” from woodworking during the summer, or renovating this shop. I choose the latter as option 1 or 2 doesn’t work for me :).
So that’s the situation. Here are my two questions:
1) I want to insulate this building. Most of the heat is coming from the roof so I was planning on insulating from that direction first, then focusing on the walls. I was planning on R13 batting since this should be a significant improvement over the no insulation that is there now. I want to avoid putting more weight on the already sagging roof so I was planning on adding joists, putting R13 between the joists, and putting OSB or some other cheap ceiling material between me and the insulation, putting the added weight on the walls. I had considered putting the insulation between the rafters but am worried about how to cover the batting and the extra weight that would require on the roof.
2) I want to “stabilize” this building: add some cross joists that will keep the wall from moving more out of plumb and keep the roof from sagging more. My plan was two fold: add 16’ 2×6 to the top of the wall, and bolt it to the top of the wall, hopefully preventing the walls from moving out more. Further, I was going to bolt 16 foot 2×4 or 2×6s to the bottom of the rafters to keep the roof from sagging more. I would do this in 3 locations in the shop. I would then add additional nailed 16 foot 2×6 rafters to hold the ceiling and insulation (prolly 24 in on center). I’ve no idea if this ought to work and if 16’ 2×6 construction lumber would cut it for either of the above applications (structural support and/or ceiling).
The BEST option is for me to get a bulldozer and “fix” it, but I would like to get a few more years of somewhat comfortable woodworking out of this shop.
