What's interesting - and somewhat disturbing - is that he assumes it
is 1/2" without checking.

He just did a neighbor's house the other day and I saw the delivery
guy piling up a bunch of 1/2" sheets of ply.

Can't say what he'd do. If reputable,he'd just put the right material in
place. In the case of your neighbor, it is possible he knew the entire deck
needed replacing and was going to use 1/2" all the way or was putting the
1/2" atop the t & g. We can make lots of assumptions, but you'd have to
call him to find out for sure.

Last summer I was getting bids on re-roofing an industrial building. One of
the quotes came back with the same wording, it was $xx per sheet for plywood
replacement. They guy was on up the roof and knew it was steel decking.
Got three bids and went with the highest bidder and saved money.
