Sistered roof beams in garage pulling away from house
Your roof seems going through some movement, the reason, or the reasons, can't be pinpointed through a few pictures. You shall go back to the original consultant engineer, who I assume was overseeing and responsible for the jacking operation occurred a short while ago. The structure may not under immediate threat of collapsing, but it is prudent to find out why (including potential hidden problems), and make proper decision from there, on whether immediate repair is required, or not.
I would insist the engineer to have a visit, or issue a statement that there is no &quot;big problem&quot;. I think he would respond differently then :) Send him the invitation in writing too.
If the engineer still refuses to visit, have a second opinion from another qualified engineer. I'll report the conduct to his licensing board, or local building official, if any problems is being identified.
