We've got a rectangular carport overhang which has become waterlogged and decayed. I would like to know the best way to replace a long span of Trilam which is about to snap.
The overhang is 25' X 22', supported on 4 posts at the corners and is additionally anchored to the adjoining house. The rotted Trilam is 25' long and extends perpendicularly from the house. The roof joists all run at 16" offsets parallel to the house and are sitting in metal joist hangars. The carport sits 13' 6" off of the ground.
I am planning on using some sort of beam supported by adjustable steel columns which can jack up the carport and hold all ceiling joists in place while we remove the rotted Trilam and replace it. Is there anything we should watch out for when doing it this way? Is there a better way to do it?
I'm not sure what type of temporary beam to use or where to source the adjustable steel columns. They might need to be fabricated custom to reach 13' 6".
Any suggestions would be appreciated.
