Gutters on a pole barn?

Never knew there was so much controversy over barn roofs! I would like gutters. Don't want all the dripping around the edges. Someone told me a metal roof won't hold snow and when it goes it may take the gutters with it. Don't want to argue that water in all forms can be a powerful force, but really would like some gutters.
The power of water.
 
In quite a few areas in the interior of B.C. you are not even allowed to put gutters on for your stated reason. I have had to do some serious repairs (back in the day) due to ice/snow damage to eves. Just sayin'.
 
My shingled roof has a 1 ft overhang. No gutters to clean. I planted flower to keep water from splashing on siding. I wanted vented eves. I didn't want cutters to clean. 10 ft off the ground could be dangerous for an old man to clean.
 
I have a 60 x 120 Walters machine shed with over sized rain gutters. They are positioned such on the roof edge that the snow slides over the top of them in the spring time. They sure keep it dry around the building perimeter. I do not have any large trees near the building and when it rains hard the gutters get a good flushing.
 
mine were ripped off last winter on the north side of the building. I have snow bars on the south side and have not had an issue.I believe they used the trim used at the bottom of vertical steel siding as the snow bars
 
My 60x80 has gutters.They position them so the ice runoff goes over the top of them.
 
Fist off, your metal roof should stick past the fascia board 1" - 1-1/4" (No Drip Edge). Install rodent guard on your roof as snow retention. Now put your gutters up as usual. The problem with installing gutters low enough for snow to go over is; heavy rain also goes over. The longer the roof panels, the more momentum the water picks up, and over the gutter it goes. One thing you can do to slow down the water on a metal roof is to install non skid surface tape. Example: the non skid tape used on steps. My supplier carries a clear non skid tape for slowing down water in metal roof valleys. No reason it wouldn"t work on metal roof panels.
 
What I use is metal building gutters. It takes the same shape as the trim which is used on the ends of the building.

I had a 36" X 45" Morton pole barn built in 1995.
It is equipped with gutters.
I think they must have built enuf of them to know exactly how to install gutters.
When it rains (I don"t care how hard) nearly all the rain is caught by the gutters.
When it snows, the snow passes over the gutters.
If there is 2" of snow and it all goes at once, it "flies" right over the gutters.
If the snow melts slowly it still goes over the gutters and forms curls before it falls to the ground.
I am still amazed at how well the gutters work; never had one single problem with them in 19 years!
I do clean the leaves out of them in late fall each year. I usually get up on the edge of the roof with a leaf blower and blow the leaves out.
That"s my experience and I live 50 miles west of Albany and we do get REAL snow sometimes!
 
In Stearns County, MN the Environmental Services folks are forcing dairy farmers to add gutters to their buildings to divert roof water from the cow yards.....
 
The gutters on old Morton buildings are steel. They are installed with bigger, heavier, longer, ring shanked nails. The gutters are not seamless. The nails (Spikes) come out very hard. Many times when pulling spikes on Morton buildings, the only thing left of the gutter is a piece of rusted tin. Pitch of roof, wind direction, and sun play a roll in how much snow builds on the roof, as well as how it comes off. When it comes to installing gutters along the eaves of any building with a metal roof, there are many factors. Barn metal roofs on houses are the worse. Installation of the roof is another factor..............
 
I have barn with a metal roof connected to the house. I have gutters on the parts of the eaves that are over the house/connector and over a deck on the back of the house. Snow and ice come off the barn like gangbusters, but I've got the gutters positioned low enough that there's never been problem with them being damaged by sliding snow/ice. Some times a thin layer of snow will slide slowly and curl into the gutter rather than clearing the gutter and falling off, but that's never been an issue either. When the snow melts and the gutter takes care of it as water.
 
Dad's 1980 Morton building *had* gutters. After a few years the snow sliding tore them off.

Apparently this was from before Morton knew how to install gutters.
