Garage Door beam sagging
After 33 years and a new tile roof 6 years ago, the beam across my garage door is sagging about 1 1/2 inches in the middle. The door sets behind the beam and is not binding.
Can it be repaired by jacking it up to level or slightly above, and laminating two thicknesses of 1/2 inch hardwood plywood on both sides with construction adhesive and wood screws?
If that is feasable, where would the seams fall between the 8 foot lengths of plywood and what type of screws and screw pattern would be best.
I appreciate your input and any other ideas
