Back caulking window nailing flanges
Is it common practice to use a specific window flange caulking for back caulking the flange before installation? Does flashing tape and house wrap suffice (assuming that it installed properly) or is caulk important in the case that the tape fails. Or, are you just adding a chance for water that would happen to enter this area to be trapped and rot the framing without knowing? I would like to spare the expense and labor of more caulking if I could but don't want to sacrifice air and water sealing at this crucial junction. Thanks in advance.
