Recently purchased a home which was built in 1960. When I was up in our garage attic I noticed the rafters were separated from the ridge board (shown as B1, A2, and C1). Im not sure if its new or was already corrected/supported with the additional support below (shown as A1). A new roof was installed in the last 20 years and it doesnt look like the roof itself has separated (B2), just the rafters. Also I noticed there hasn’t been any movement at the second cross support (A1). Should I be concerned about the rafter separation? If so what is the proper fix?
Also, on a second note the tie beams run perpendicular and 4’ apart. We needed additional storage so I built an shelf which we tried to anchor mostly on the inside wall of the garage supporting the other opposite rafters (see D1). I dont see an issue with this construction but im not sure if this could be causing any of the separation of the rafters as mentioned. Please advise.
