I used to install deck ledgers over
pressure-treated spacers that I ripped
on site and flashed to the siding. The
space kept the ledger from rotting,
but the spacers took some
time to cut and install. Fortunately,
two new products
make the job a lot easier.
The Flash Block is a
1/2-inch-thick aluminum
spacer that
you can sandwich
between the ledger
and the siding. Its
diamond shape
permits easy water
runoff, and an offset
9/16-inch-diameter
hole (large enough for a
1/2-inch bolt) ensures
that the Flash Block hangs
plumb during installation.
Suggested retail prices are
$1.99 for the 5-inch-long blocks
and $2.59 for the 7-inch ones.
They're available at some lumberyards,
or you can order directly from
the manufacturer.
