This was on a saltbox style house…not sure on the age. 2x4’s on the short side then on the long side the top half was 2x4s then switched over to 2x6s on bottom half. It seems to me that the rafters are mostly supported at the ridge by the 2x8 header beam. Overall span about 24’ with one support in the middle. The 2x8 header doubled up in the middle but it’s only 1-2x8 on each half.
It seems all a little jimmy-rigged to me but I’d appreciate any advice on what exactly is defective…considering its an old house. Thanks.
