I have two garage doors that both occasionally experience water coming in. This happens on rainy days, but only when the wind is against the door. The grade is OK, except there is an inch or less of depression right in front of the door – it's like the door fits down into a groove. So water doesn't run from the ground into the garage, however water runs down the door itself, pools in the depression, and eventually gets inside. My actual problem seems similar to the one in this question, however I would like to ask for review of my own remedy idea:
I would like to put something like flashing to extend a lip out along the bottom front of the garage door(s), to direct the water running down the face of the door away to the graded slope (less than an inch away).
What materials might work for this? Metal flashing is obviously a possibility (not sure I have the skills for this). Being DIY-minded, I'm thinking about experimenting with a stiff waterproof canvas – if not stiff enough, glue two layers together. I could glue a thin strip of wood or some kind of small profile moulding along the bottom of the garage door, then after it is firm, glue a strip of canvas, held tight at a 90 deg angle above and along the top of the wood strip, so it would make it stick out. Think it would work, or would I just be messing up my door?

Try this idea before you mess up your doors. Cut small drainage grooves on the outside of the depression to allow the water to escape. A small kerf at either end and maybe one in the middle should be all that is needed.
