I am considering to build a patio with a roof. I am debating whether to
use
16" squared patio stones, or using trated 1.25"x6" deck boards on
top of 2"x4" treated studs, flat layed. That will leave 1.5" space
under
the deck board.

Eventhough I am going to put 4" of gravel underneath, I may still have
some
drainage issue. Will mold grow under the deck board? If it does, will it
grow
to the otherside (deck surface)?

It will be a small patio/deck (16'x16'), covered with those pieces of
clear
plastic roofs, outside the doors of the walkout basement.

Thanks. Y.
