As in all construction, everything is in the details. If you build it
poorly, no matter how nice it looks, it won't last long. Those boards
go by a lot of names: water table boards, aprons, water boards and are
primarily a nice architectural element. They're not limited to use
with clapboards, should always have flashing below and can be made
from something like Azek (expanded PVC wood substitute lumber), so rot
is virtually eliminated. Azek holds paint beautifully, which
considering the location and exposure, is of prime (pun not intended)
importance.

Here's an example that omits the flashing.

In some situations I might use Ice & Water Shield (or approved equal),
but I'd always put something back there.
