Saw these on a trip to the Harrisburg area of Pennsylvania.
They are “snow birds”. It breaks up snow as it melts and falls off the roof so it doesn’t come down in giant sheets.
Snow guards
They break up the ice-sheets when snow / ice freezes on your roof.
They are ice and snow catcher things. They come in different forms, sometimes bars and these new versions in your picture. They hold the snow and ice in place during the winter.
Ice and snow will build up and weigh a ton, sometimes literally, and that weight falling on someone could easily kill them. With this system you are far less likely to have the entire sheet come down and it lets the cold stuff melt on the roof instead on people’s heads.
idk if this is the same, but in my country we have things looking like tiny ladders standing on their side in exactly that location on roofs to stop a big load of snow going down at once, possibly hurting someone unsuspecting standing below
yeah that’s it. i researched the name in my country and translated it to “snow guard”: https://images.app.goo.gl/KmfEtxJa3CjDwkCg9
Snow guards or snow stops. They keep the snow from dumping off the roof quickly.
Solved!
Hi OP, unfortunately we don’t have a way to add flair to a post, so can you please add “[SOLVED]” to the end of your title? Thanks!
They keep built up snow and ice from sliding off of the roof and injuring people. You’ll usually see them on roofing near or overhanging walkways and sidewalks.
