After an incident of blowing snow, check the attic. If snow has entered, remove it before it has the chance to melt to avoid possible damage to the ceilings.
During prolonged cold spells, ice build-up at the eaves and on plumbing stacks and fans is common. The condition occurs when snow and ice accumulate, and gutters and down-spouts freeze. As part of your regular maintenance, remove the build-up of ice or snow once it is noticed.
