I would say, it would certainly help. Remember with the huge surface areas involved with houses a few psi can result in a couple of tons acting on a surface. in fact as an experiment try opening your front and back doors in a moderate breeze you should find one or other slams shut and takes a bit of a pull to open (assuming the winds in the right orientation w.r.t. the doors/
