I am in the process of stripping old shingles, putting plywood over old sheathing and adding new shingles. The roof is over an attic that was converted into a bedroom. The current roof has a ridge vent but no Soffet vents. I was told that the best way to add a soffet vent is to put strapping down between the plywood and old sheathing in order to create a ventilation space. Then cut holes in the top of the old sheating over the eaves. Then put he plywood down, cap the space and add the vents on the bottom side of the eaves. Is this the correct way to do this???
Thanks in advance!
