Northeastern Connecticut Planning Region Snow Load: 24.5 psf
What ASCE 7 says about snow load in Northeastern Connecticut Planning Region
That's Northeastern Connecticut Planning Region's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from.
Converted to something you can actually eyeball on a roof: about 53.9 in. of fresh powder, 19.6 in. once it settles and packs down, or just 4.9 in. if it's turned to ice. This is a meaningful design load - most modern-code homes handle it fine, though an addition, a carport or a flat-roofed section can be a weak spot.
