I was waxing my car this afternoon and something crossed my mind as someone who is continually concerned with snow shed on a cabin in the winter. Is there some kind of similar product for a metal roof that enhances the slippery factor?

Rainex windshield washer fluid. Winter mix.
I don't use it on the roof per se. But I shoot it on my roof mounted solar panels in the winter to remove and prevent the snow build up without having to climb up and brush them off. But it does seem to keep the snow off the sheet metal below the panels.

Darz... does this work well on the panels? How long have you been doing this? Any damage? Rains X doesn't recommend the use of their products on solar panels, undoubtedly a liability issue.
Ours are near the peak of our roof, 12/12 pitch so the snow has to stay on until it melts enough to slide, sometimes a couple of days. This season I mounted another 750 watts of PV to the front of the deck where I can reach them to sweep snow off. Would love something that would help the snow slip.

I will start a different thread so I don't hi jack the OP original question.
But to be honest. Until I read the OP, I never really put 2 and 2 together regarding his question about treating the metal roof. But realized that the run off of the rain ex quite possibly helped the snow slip off the metal roof panels.

Keystone what pitch is your roof? We have a firewood shed with a 3/12 and never clean it off. It usualy slides down near the bottom then off when the weather warms a bit.
Also how much snow and what type of construction is the shed?
Nobadays your getting snow staying on your pannels with a 45* roof? Is the roof metal or something else?

Roof wax. I find that funny. I use snow guards as mentioned in another thread just now. I want to snow to stay up there instead of sliding off to;
-not fall on people
-not pile up around the foundation and block basement windows

Brett... metal.... picture in THIS thread. Porches on each side slow down the slide of snow.

I don’t have the exact pitch for my roof. It’s mid 50s era frame construction on a rock foundation deep in the Wyoming mountains where I’ve seen 6+ feet on the roof before. It has a lot of weird angles too which prevent a smooth runoff. I’m not concerned about snow falling off the roof.

Winter before last we had 10' of snow on the ground, last winter only about 5 feet. We are fortunate that the snow on the steep part of the roof slowly pushes the snow off the porch roofs.
If you don't climb up on that roof very often it might not hurt to experiment with some kind of chemical like RainX. Wh er n I worked for the city we used to get a chemical from one of our suppliers to spray on the snowplows, loader bucket and in the dump trucks. I have no idea what it was but it worked! Lasted a long time as well. Without it the snow tended to stick in the loader bucket and the dump truck beds, with it, slick as a whistle! I do remember the truck beds being a bit slippery if you had to get in there.
We got it from Marx Chemicals (don't think they are around anymore) if I remember correctly... THIS must be similar stuff.
