I am in process of remodeling. I currently have T 111 sheeting on the house as sheeting. I plan on adding 1 inch Tuff-R board outside of this before siding. A deck will be built along this wall. What I want to do is put the Tuff-R sheeting on and then bolt the deck ledger board through the Tuff-R, T 111 and into the rim joist with carriage bolts, put the flashing on then deck it, then put the wood bevel siding on the wall. Since there will be an inch of that Tuff-R insulation between solid wood, is this advisable? I could put the ledger on before the insulation, but I don't want to do this unless I have to.

If you want the insulation behind the leger board you will need to provide some backing blocks where the bolts go thru. If you don't do this it will be like bolting the leger to a stiff sponge. The leger board will loosen up after time as the foam compresses

That was my worry, that it wouldn't stay tight, but work itself loose.

you can't put wood siding directly over foam,especially one with an aluminum facing,you need to put furring strips over the foam first

Make the deck free standing and there will be 0 chance of wall damage.

That is an option I thought of too, but have not seen it done. I will have to research that some.

You cannot attach the ledgerboard to ANYTHING but structural grade boards. This means you need to remove your T-11, foam siding and everything else.

Alot of people use the water&ice self sealing membrane for flashing right over the rim joist. Then you attach your ledger right to that. Make sure you flash over the top of the ledger, and your siding comes down over it to direct water AWAY from the house.

Check out www.decks.com for a great deal of good info.

I love my free standing deck, but it has 6 12" piers instead of the 3 it probably would have had if it had been attached.

Also make sure the decking surface is at least 4" below any door opening to prevent water from getting in under the threshold.

When I get stuck having to attach a ledger to a house I use Storm and ice on the wall under the siding then I use 1 X 6 shims cut to the width of the ledger sitting vertical as shims to space the ledger away from the rim joist on the house so water does not have a place to lay and rot out the wall or ledger.

Install the deck boards about 3/8" away from the siding for drainage.
