building second level of home. Plans call for siding over existing 4x8 cedar siding. Two out of three contractor I have talked with have suggested pulling of cedar sheeting and attaching siding. Architect and carpenter both suggest furring out upper floor studs to enabling siding to go up evenly. Neither contractor has seen current siding. It is not bowed, warpered or uneven. I would like to avoid Hassle/expense of removing if neccessary. What do you recommned?
I would leave the current siding sheets in place. Most likely it performs a bracing function, at least in the corners. By your description, I assume this is 5/8 fir or cedar faced plywood. If so it is part of the structural integrity of the building, just like plywood sheathing. Don't remove it without applying structural cross bracing (what a pain). The need for furring strips is also questionable if the siding is flat. Applying the new siding directly over the existing sheets will minimize the need for adjustments at window and door jambs and sills. Follow the plans, keep the budget, don't remove the sheet siding.
