It's now the middle of December and nothing says winter is here quite like the first snow of the season. Snow is one of the worst perceptions your roof endures every season.
The danger with snow are snow drifts especially on buildings with older roofs. This is due to how much pressure the snow puts on your roof. For every 10-12 inches of snow equals 1 inch of water and 5 lbs of pressure for every square foot. This metric can also be used with dense packed snow measuring in at 3-5 inches tall and still meeting that 1 inch and 5 lbs of pressure mark.
With fresh snow blowing around it's very easy to see up to two feet of snow of some roofs depending on how tall the roof is and how bad the gusts of winds are. Make sure your roof is structurally sound and prepared for the winter. Add supports if needed to ease the tension put on the roof.
Also keep a lookout for basement windows, drains, basements, and anything else that may be underground. Flooding as a result of a lot of snow melting quickly and is hard to fight when the flooding starts. Ensure your seals are good and add sand bags if needed.
