Garage ceiling joists meet in middle of garage but are “floating” - are not supported by wall as they are in the rest of the house. Attached garage is 11’ wide x 21’ long.
Is this acceptable because it’s not part of the living area?
If not, how should I correct this? Run support beam underneath ceiling joist across 11’ width of garage? (2x6’s? 2x8’s?)
Someone suggested laying a 2x6’ on top of side walls and supporting the garage ceiling by “suspending” the joists from this 2x6 instead of supporting the joists from underneath. 2x6(s) would run above and across joists like the 1x6 is in the photo, but in vertical position.
Any idea what’s the shiny stuff on the garage door header? Is this some kind of tree sap or could it be some type of mold?
