"There are 4 wires coming out of the roof. One seems to be hot, a
second hot and switched
from a wall switch, one ground, and one neutral. "
With only one wire coming from the switch, and one direct hot, your
choices are limited. You can only control either the fan or the light
from the switch, not both. The other option is to get a remote, with
which you can control both. In that case, the little box that comes
with the remote gets wired direct to hot and the fan and light then are
wired to the little remote box.
