Water leaking under garage door after rain storms

[kdrymer]

We just had a pretty heavy rain last night and all but the corner was dry afterwards so the flashing and the notches we made in the driveway seemed to help. I'm thinking the reason the interior corner was wet was because the flashing we installed was bent upwards at the corner, easily allowing water to seep in underneath it. I plan on putting a silicone adhesive underneath the flashing to adhere it to the concrete.

There is a chaulking for concrete, not silicone. It may not stick to the flashing.

Don't leave that flashing edge turned up like that. You can cut it with a sharp utility knife.
