I’m not a cold weather roofer (not in the slightest) & maybe some of you Yankees can help me out…
Maybe even a Canuck or two might know.
Is this some sort of ice damming system or maybe it’s steep slope roof jacking for a structure that’s going to be worked on (or is in process maybe for roofing, prev. maint. or maybe painting?).
Help me out here.
PS: This is in Junea, Alaska.
