I was in a home today that was newly remodeled (less than 2 months) and they had taken about 10+ feet of a load bearing wall plus a door way out to make an open kitchen design. The contractor suggested to put a support beam across the span like what would be common. The customer was not happy with that so the contractor said he would do the work in that attic and she wouldn’t see it, she said great. The job wasn’t permitted and there was no consult with a structural engineer. Now to the question. It didn’t look right to me but when I was in the attic I noticed that all he had done is about every 2 truss he sister’d a collar tie and a rafter tie to the top and bottom to “reinforce them” and thought that would be sufficient to remove about half of the load bearing wall in this house. I told her to consult an engineer but I was wondering if anybody had any literature that I could read on the matter or if somebody new if this was an acceptable alternative to a support beam.
The trusses are typical 2x4 trusses and the roof did feel a bit on the spongy side and it had a bit of saddle back going on but don’t know if that was from before. The contractor if he was one also told her she didn’t have a load bearing wall in her house so they could do anything they wanted with out concern.
No pictures to provide because I was not on a home inspection.
