get a metal roof , they shed snow in one whoosh,
but install some 'snow stops' to prevent the snow from coming off.

This likely means you didn't put enough of the stops on. Many people just put one or two rows of stops on and think that is good but on big areas it can require a lot more.Enough snow rips the stops off and mangles the roof.. been there done that.
Anyway, lots of ways to keep the snow on, or off, the roof and they all seem expensive when done right. Areas that get a lot of snow are a big challenge to deal with.
we use bar type snow stops all the time. All over Canada. They don’t rip off, even with lake effect. Stick on ”snow shoes“types also work alright.You would find those things on the ground after spring thaw. Might work in mild climates where the snow is all gone after a week, but not where it accumulates for three months.

Metal shingles, no more sliding like on a smooth metal roof, but expensive

The whole issue isn’t getting it off the roof or keeping it on the roof it is not damaging things when it comes off or stays on lol
Guaranteed you get more snow than we do here on average but I just make sure not to park things I care about under the overhangs. It sure ***** but makes spring that much better when it arrives. As far as pipes and such getting ripped off when snow unloads I have either moved or installed from new everything going through the gable walls. If this isn’t possible build a really steep roofed awning over the pipes. I helped a neighbor build one over his boiler intake/exhaust pipes and he covered it with expanded metal instead of tin. Says it works amazing as the snow still sort of goes through but it doesn’t destroy the pipes or the awning when the roof unloads.
I don’t have any product suggestions as I have found nothing on my own to make the snow fall slowly. Well short of heating the roof so it turns to water when it hits the roof and that is not practical.

Put on so many there wasn't any more roof to work with. It's all about how much snow (weight) and weather conditions, aspect, etc.This likely means you didn't put enough of the stops on. Many people just put one or two rows of stops on and think that is good but on big areas it can require a lot more.

Most of the conversation appeared to devolve into the usual GJ overthinking and recommending a complete teardown and rebuild. That's when I lost interest. As usual, GJ participants can find a multitude of ways to make a simple solution into an expensive, complex one. The roof structure needs to be designed for the snow load, obviously. The continuous angle iron snow fences won't get ripped off if anchored properly. This is also why you see multiple rows of snow fences to spread the load. But hey, feel free to suggest that the OP do a complete teardown (or roof removal) to fix this problem.You missed half the conversation it seems.

In some conditions, you shouldn't be trying to keep it on the roof. It sounds like you get some crazy amounts of snow!Put on so many there wasn't any more roof to work with. It's all about how much snow (weight) and weather conditions, aspect, etc.

Winnipeg had 140 cm of snow lat year. That’s 55 inches.we use bar type snow stops all the time. All over Canada. They don’t rip off, even with lake effect. Stick on ”snow shoes“types also work alright.
1/7th of a good snow year, and 1/4 of a typical year in the snow belt.
Winnepeg also has 320 days of sunshine per year, compared to 154 in the lake effect snow belt.
I’m sure sticking things on the roof work just fine there.

About 6.5ft so far, granted not that much on the roof.In some conditions, you shouldn't be trying to keep it on the roof. It sounds like you get some crazy amounts of snow!
Supposed to be designed to 50 psf, but given the **** workmanship on other things, I'm not confident I can trust that.
When it rains or gets warm, the snow is a sponge and that's an incredible amount of weight.
I didn’t mention Winnipeg anywhere in my post.Winnipeg had 140 cm of snow lat year. That’s 55 inches.

I read through the whole thread but missed what type of building this is? If it’s a heated building with attic space, have you checked the insulation? A well insulated and well vented attic should help to keep the roof cooler allowing more of the snow to blow off. If your unsure what snow load the roof system was built for, have someone take a look at it, if it’s capable of holding snow loads in your area then install some type of snow bar If you want more of the snow to stay on the roof. Should be lots of information on the internet for you to find the one that suits your needs. If the roof system isn’t built up to par then I would t instal any snow bars except to protect utilites, hydro mast, vent pipe, etc. And door. There’s most likely no strapping beneath the metal where you need it, so you would have to lift the metal panels and put your strapping on first of course.

For safety its gonna need a new concrete pad first, gotta do it right or we'll all die.do a complete teardown (or roof removal) to fix this problem.
