I've recently purchased a home. Home inspector said nothing about the back porch. As I watch more youtube videos on framing and general home improvement, I look at my enclosed porch and think there may be some structural issues. Would like input on how I can make this a little more solid and safe, as I don't want to tear it all down. I've attached pictures. Here are some things I've noticed.
1) Obviously, the ledger boards are attached over the siding, which is wrong. I noticed there's not much holding the rafters in place on there other than nails. Are there such things as rafter hangers (as opposed to flat joist hangers)?
2) Unless I'm missing something, shouldn't there be lag screws somewhere where it attaches to the house?
3) At the bottom of the roof, the notch on these rafters looks very big. They appear attached to that 2x12 with nails, which is sitting on the notched (I assume) 4x4 posts (4 of them). Are those ok?
