Snow guards

[mykleh]

one other thing to think about is area around when it comes off.. here are pics of when it comes off my garage.. I made sure I had enough clearance on each side of the building clear for it to have somewhere to go and not smack back against the building or fall on something..

Metal roofs can be a funny thing.
My cabin had a 12/12 (45 deg) roof that I wanted for snow loading.
Darn thing never shed snow except early spring, and then womp it let go!

It once let go and tore out the hydro pole as well.
It was built 50 years ago and handled those snow loads OK but sure was a concern every winter.
I had added snow guards as I feared somebody getting crushed when the snow load let go but the guards got torn away.

Roof was well shaded and cabin well treed in so wind and sun sure did not help.
Most often I'd have up to 5 ft of snow piled on that steep roof, impossible to walk up the slope except after a few snow events it was a breeze to do so.
Wasn't lack of insulation (R 40 or so) or ventilation but sure stuck on.

yeah I find my house's metal roof (one side has snow guards other side not) because it is well shaded with maple trees has gotten a residue on the metal making it much less slippery which is a mixed blessing.. makes going on the roof to clean chimneys way more comfortable as when it was new I was wiping my shoes on tar paper to make sure no dust or anything else was on my shoes as it was like greased lightning.. in winter I do take a roof rake and take the first 1-2' off the front edge so if it drips it doesn't get frozen to the gutter plus the sun hitting the bare metal helps.

At the cabin a few years ago during the winter the roof bellied and had to have the walls pulled back after crew took off 5 sets of shingles that had been applied since it was built in 1937. I recommended replacing with metal roof as cabin wasn't occupied in winter and snow would buildup. I figured the sun would cause the snow buildup to slid off which it did but when metal roof was installed they also installed snow guards which after first winter were ripped off by snow and ice sliding off when no one was there. Guys also had rain gutters around the cabin but did not get touched because they were on porch roofs. The headaches with them were buildup of leaves every fall season. Never could understand why they were on a cabin in the woods?

I'm looking to add snow guards to my metal roof barn. The metal roofing has a Kynar 500 paint and my contractor wants to use the SnoGem polycarbonate ones that adhere to the roofing. He says this protects against rust from metal to metal contact. Thoughts on this?

I'm a little late to the party on this, but did you find a good option? I'm thinking about ace clamps AceClamp.
