I have a garage that is approximately 26x26. The roof is pitched 15 degrees. The joists span the width of the garage with no center support that goes to the ground. Judging by pics and diagrams on the internet, the trusses are what you call "gable end". Nearly half the rafters and joists are rotting on one side due to water damage caused by the previous owners creative gutter work. I believe the unorthodox gutter was due to the neighbors relatively recent construction of a garage less than a hand-breadth away. (I dont recall the inspector actually examining the exterior on that side.) Some of the top plate is rotting also.
My plan is to cut the rotting portions off and splice in new wood with rigid mending plates.
Which size mending plate should I use?
How many do I per splice? How far out from the splice should my temporary support be?
Do I use a 4"x 4" post(s) or a jack post(s)?
How many joists should I jack up at once to get at the rotting top plate?
Should I add permanent center posts for additional support?
