I just purchased a first home, and do not want to spend a lot of money if at all possi ble. I have noticed that the center of the eave of my roof is sagging. The back side of the roof is as well a bit. I went into the attic and noticed that a few of my trusses are cracked. My question is, what are the pitfalls of jacking up the roof by a couple of inches and rebracing? It seems easy enough, but I am not sure. Is there a good article to look at, or can someone please help? Thanks.

Welcome joele,
Wow. Was this problem disclosed (previous owner's disclosure form)....and what about the inspection report??? Hopefully you knew about this problem before you bought. For example, are there more than 2 layers of asphalt roofing (VERY HEAVY) up there?
I hope I'm wrong...but doesn't sound like a cheap fix to me. Best of luck...and keep us updated.
Generally when repairing damaged trusses a structural engineer must be involved. I do not recommend you try this without a structural engineer’s approval first but the repairs will usually go like this:
You will sister a new member along side the broken one and securely nail them together for the full length of the repair (6-8 inches apart in 2 staggered rows). The repaired area generally needs to overlap a minimum of 48” – 60” each way centered over the break and the new wood must be of the same size, species, and grade of wood as the original truss.
Like K2 I also would check into the disclosure clause as well as any inspection reports. Any additional loading added to the roof after the initial construction would also be a concern.
