Exterior Door Replacement Q...

I've got a bit of a predicament with my exterior rear door on my house. About 10 years ago, I built an attached deck and didn't remember to lower the deck so it wouldn't be flush to the door (which it is). The door is black and the plastic around the window in the door which has made it leak when it rains hard. Also I think it's leaked under the door and is rotting my sub-floor in the kitchen. I know I'll have to replace some of the sub-floor when I install the new fiberglass door. My question is, will I need to do something different as far as flashing to keep the bottom of the door from leaking? I can post up some pictures if that helps.

Replace any rotted material when you remove the old door and install your new door on a door flashing pan. Flashing pans used to be constructed of copper and fit into the base of the rough opening to keep any water from getting into the building. These days there are nice plastic door flashing pans that are adjustable in width and even have small ribs in them to keep the threshold slightly off the base of the pan which is sloped away from the building. I'm sorry that I can't think of the trade name of the product but I have seen it at real lumber yards (not box stores)

Are you talking that the water cannot run away from the door? I would raise the door an inch or two when you replace it.

If I raised the door, would I have to cut into the header, siding and run new channels around the door?

You will have to raise the door atleast an inch. The door now hopfully is an 80" tall door. You can buy a 78" tall replacement

If you raise the door, you'll have a trip hazard when exiting. Check your threshold type, if it's relatively flat replace (pain) with a nice tapered one that will help with water control. It'll be adjustable and with the proper sweep under the door slab, it shouldn't leak. If you live where there's snow, keep it from drifting up against the door.

The replacement door I've got is the same size. I would have had to special order the shorter size. The guy who was going to replace the door and do some other vinyl work went with me when I got it so I figured it would work. He was talking about raising the door, but was having some reservations. He wanted to come by and look at it but he's not returning my calls. Here are a few pictures.

you seem like you have the hight, just flash the new door in rite. The water landing on the deck, off the deck, is hitting the door, add gutters or an over hang over the door.

If I understand what I'm seeing in your pictures I would flash under the new door down over the outer edge. Caulk between the sill and the flashing.
