You need to properly insulate your attic... probably no insulation at
the perimeter.

No it has something to do with the downspouts being frozen and snow
melting and refreezing on the roof.

Downspouts are below the gutters. Ice dams in the gutters can cause
water to back up into the soffit where it can freeze and destroy your
roof and eaves. You'd be wise to clear your gutters and downspouts
before winter and check often during warm weather. Often gutters and
spouts are too small to handle the water volume. Ice and icicles form
from loss of heat from your house into your attic/eaves... snow melts
when sunny and freezes at night, check for insulation, and for proper
air circulation too. Do not let this pass, once water begins to run
down inside your walls the damage can be horrendously expensive to
repair, can even fracture your entire foundation. Your homeowners
insurance will not cover water damage from neglect.
