Hi everyone: I’m building a timberframe/SIP house on an ICF daylight basement in coastal AK- I have a question about the deck ledger.  I know that one usually puts a self-adhering membrane behind the ledger, but I am wondering if that is appropriate in my case.

We had the “Leaf relief” type; Gutter Protection – New England Gutter Kings (negutterkings.com)  When…
