I have a two car detached garage surrounded by yard except for the front which has a gravel driveway leading into the garage. The gravel driveway is higher than the floor of the garage and there is a slight dip going into the garage. I have drainage so that isn't the problem.
I want to raise the floor of the garage higher to elimate some of the dip from the drivway to the garage floor.
I have an automatic garage door opener. If I raise the garage floor will the door have to be adjusted for the shorter door opening?
I have attached two photos, one open and one closed.
