This was a remodel inspection. They basically added a slab for a couple of rooms and took part of the roof off to re-frame the roof to accomodate the new areas.The old roof was a truss system and the new portion was stick framed. The trusses are not used in the new portion but where they tied the new new roof in with the old, they attached (scabbed onto) some of the new 2x8 rafters to the old trusses without the new rafter ends bearing on the exterior walls. See photos below. Note the 2x4 brace under the rafter near the end. I could not determine if this brace went to a bearing wall, but not all had these braces anyway.
Some trusses were chopped up and although they are no longer effectively holding up the roof in this area because the rafters have been installed, the bottom cords are still used as ceiling joists. I'm thinking that this may result in problems down the road.
I don't know whether an engineer was consulted for this design. It does not look engineered to me.
I know that the IRC says this about rafter bearing:
802.6 Bearing.
The ends of each rafter or ceiling joist shall have not less than 1 1/2 inches (38 mm) of bearing on wood or metal and not less than 3 inches (76 mm) on masonry or concrete.
Several rafters are configured like the one in the photo or similarly. The contractor did pull a permit but it hasn't had a final yet. I find it difficult to believe that this is acceptable or that it got by the B.O.
Any thoughts?
Thanks,
Eric
