WWFD? (What Would FABO DO??)

Yes. and from my limited understanding that last 3' or so is not insulated from underneath causing the 'drift' over the eave. So basically this is a huge eave , ya? I may not have enough length to zig zag but I could get another bundle. It only sees snow once a year for like two weeks, but its heavy stuff because of the rain that inevitably comes after.

Good idea, thank you!
if i understand it correctly, the zigzag pattern also creates a V shape for the melted snow run off to slide down
