Your other advice is excellent!!

I have to agree that I have never heard of or seen sheathing being cut back for a ledger attachment. I would also caution against flashing under the sheathing and over your ledger as you expose the end cuts on the plywood sheathing. You want flash between the siding and the sheathing as the diagram above shows.

Trex just like the plastic and wood fiber it is made from initially will simply be reprocessed and made into other products, not put in landfills, it is to valuable to do so. That is what is so great about this/these products, they can and are reprocessed so that they do not end up in our landfills for eternity.
Pressure treated lumber I agree is a thing of the past or will be so very soon. I hope the NH DEP will soon outlaw it's use for decks and walkways as it appears there are some who do not realize the harm they are doing to our environment with the use of this product.

But as of today there is no feasable way to recycle these materials, that I know of (if you know of a place, please let me know as it is important to expand the horizons), so we are at a hope and pray we find a use and a way to deal with them. You still will be very limited with what you could do with them as the wood fiber is a deal breaker when it comes to making new plastic materials.
