We have a pole barn. It's covered with modern painted ribbed steel.
The steel on the roof extends approx 6 inches past the wall, thus the
end of the roof steel sheets are sticking out, with no framing (wood)
under them. This makes sense because otherwise all the runoff water
would run down the wall.

I want to install about 12 feet of rain gutter above the 9 foot long
sliding door, so there isn't always a mudhole in front of the door
during rainy seasons. (the rest of the barn does not need gutters).

The problem is, how do I attach the gutters with this 6 inches of tin
hanging past the wall? (Cutting off the tin is not an option).
I dont care what type of rain gutter is used. It can be the modern
K-style steel, or the plastic, or even the old fashioned round stuff
(if they still sell it). I don't intend to use a downspout. I just
want the water from the roof kept away from the door. Besides the mud
in front of the door, if the wind is blowing a certain way, the roof
water blows inside the barn when the door is open (which is usually is
during hot weather, so the animals stay cool).

Does anyone know how to deal with this? Do they make a special gutter
for this sort of application? (I did think if stacking several 2x4's
and attaching them to the wall, but that seems rather clumbsy and ugly
in appearance).

Thanks for all help.

Rather than a gutter, you can create a sort of dam above the door on the
surface of the roof.

Just get two 8 foot pieces of aluminum angle (you know it has an L shaped
profile) AKA angle iron

You can drill and use sheet metal screws to attach it to the top surface of
the roof above the door in sort of an inverted V shape to direct the water
to either side of the door. Use silicone caulk on the screws when you drive
them. This also helps deflect snow slides over the door better than
gutters.

If the roof is made of corrigated steel this won't not work because the
water will only run striaght down the corrigations and won't be deflected
sideways.

I hope you understand it without a picture.
