I have a cantilevered overhang on my second floor which I recently re-insulated. In order to remove the old insulation, I had to remove the wood soffit and house wrap where the soffit was (the house has vinyl siding). Currently, I put up primed soffit with screws and caulk so that it was closed in, understanding that it could be a temporary solution. I'm assuming I need to replace the house wrap, if so, what is the best way to piece it together (I just cut it at the 90 degree angles)?
House wrap is important to stop moisture that might make it through the siding, driving rain, wind, siding sometimes cracks, the wrap will protect the plywood and help with wind pushing into the walls, when you put it back staple it on the tape the joints with the proper tape.eg; if it's typar then get typar tape.
