I've decided that my new house doesn't really need rain gutters. I'm in
Southern California, get very little rain except in the winter, have no
basement, and have substantial eaves draining water away from the exterior
walls. However... my front porch has a small roof of its own, probably no
more than four feet in depth. It's just shallow enough that people standing
on the porch waiting for the door to be opened are exposed somewhat to the
dripping off the porch roof. I don't really want to put a rain gutter on my
porch roof, but I would like something to sort of divert the sheets of water
from the center front edge of the roof. Is there some sort of device that
would divert or funnel water rolling down the roof away from the center
edge, letting it pour off the left and right edges of the porch roof? And
if there is such a thing, what's it called?
This was talked about in an episode of TOH. What Silva did was to make
a diverter out of flashing metal and install it on the edge over a
door. In your case it would go on the edge of the roof over the door.
It was made of 2 pieces of straight flashing each about 30", and bent
at about 75 degrees (not quite an L). They were mounted kind of like
an upside down V over the door. They met in the center over the door
and the edges were mitered to make a peak. The angle of the V was
about 160 degrees.
