Improper ventilation can create ice back-ups from the heat inside the home causing the snow to rapidly melt and freeze. This can cause costly water damage to a home during freezing weather. Additionally, improper ventilation can lead to higher energy consumption, as your heating system will have to work harder to maintain constant indoor temperature.
Snow and ice can be damaging to roofs and gutters as they become very heavy weighing on your home. With the expected snow storm heading our way tonight, make sure your home is protected by maintaining proper drainage, installing insulation and consider purchasing a roof rake from your local hardware store to remove excess snow.
