Porch Ceiling Joist Hangers

Good morning,

I'm in the process of building a porch. I've got a quick question that hopefully someone can help me with. The exterior of the house if clad in rigid foam insulation. When connecting the joist hangers for the ceiling joists, so I A) install directly over the foam sheathing, B) cut out the sheathing and connect directly to the house, C) install another ledger for attaching the joist hangers? This is going to be a shed type roof, vaulted with no ceiling. I'm planning on tying in each of the posts to the house, which is why I need to attach the joists....if that makes sense.

The hangers help connect and carry the weight, so you would not install them on foam or on the sheathing between studs.

Attach a ledger to the wall studs with Ledgerlok lags, then joist hangers on the ledger, using the fasteners designated in the specs for your hanger.

You need to attach the hangers directly to wood! I'd cut the foam back and install a ledger to install the hangers to.
