I called Milgard and spoke to someone who said it can be done no problem, but then, I just spoke with a local Installer who said you can't, it would cause possible leakage issues (at the screw holes I think he said) and void the warranty. This is in San Diego and we do occasionally get rain.
So can you change the handing? If not, could you get a new set of doors but leave the jambs??
These doors are installed in a stucco wall without any roof overhang above, it's the door on the right
