I am a home owner with a 40 year old garage which has a 16 ft. opening. There is a room above and the joists rest on the beam. The beam is three 2x12s nailed together. The beam has been sagged for along time and it has become more noticeable since painting the shingles and trim in contrasting colors.
I would like to repair this problem and need advice as to how far to take it. Options range from replacing shingles and trim for cosmetics all the way up to replacing the beams or adding a column.
It seems like replacing the beam or adding another next to it would be difficult because the floor is also sagged and it will resist straightening. What about adding another smaller beam as a stiffener?
Also, I could pour a footing and put in a column but this would create small openings. Even so, I lean towards this solution as the strongest. It probably should have had a column to begin with.
I would appreciate any advice on this.
