Well I dove rite in and started to scoop the debris off. I completely shoveled it off 3 yrs ago and now it is almost 10" deep in some spots, lots of trees around it.It resembled a thick layer of peat and was surprisingly fluffy and most of it light.
I used OSB for me to walk on as it unfortunately seems to have several soft spots
I chopped into one soft area and found ship lap running across 2" x 6" ceiling joists(not 1 1/2 x 5 1/2). the ceiling is vaulted so on the bottom of this is vapor barrier and gyproc with fiberglass insulation. Not what I thought was there. My thoughts would be that I have to strip the ship lap, strap it (for cross ventilation) then new ply. I was considering adding a layer of rigid foam insulation as well to make it more efficient and reduce the cold(condensation) on the joists.
does that seem correct, any suggestions?
Once I reach my 15 posts I'll post pics of my progress:thumbup:
