    metal rafters

    I have four sagging rafters in garage in my 1952 home. They are 2x6 and all side by side. All four have knots in about the same location, resulting in sagging. I got 4 2x6s to sister these, but that's a lot of weight to add side by side. So, Im thinking of using angle iron, as least for two of them.


    Thoughts?

    4/12 pitch. 12.5' rafter length. Single layer of shingles, which will be removed and replaced soon. House has no trusses or rafter ties. I will be adding a few rafter and collar ties.

    Can you post a picture of these sagging rafters as well as the knots?

    Also, have you consulted a structural PE on this issue? Splicing a repair vs replacement is what I'm thinking.
