exterior door threshold slopes towards door
I’ve recently discovered that the threshold on the door leading to my “flat” roof balcony is not only not properly sloped, if anything it actually slopes toward the door. The door threshold is really deep, about 18″, so this makes the problem even worse. I’ve been trying to figure out what to do about it, and at a loss. Do I have any options besides removing the door, tearing up the deck membrane and doing it all over again? The builder is long gone and of no help.
