|Your home should be a respite of comfort, even during the most humid months in Wisconsin. However, that can be challenging when one of the most common problems homeowners face is inadequate attic ventilation. Poor attic ventilation can make your home unbearably warm and cause damage to the roof (e.g. fatigue the sheathing) when moisture gets trapped. This will also increase your energy costs as your air conditioning is run more to dissipate the heat.NOTE:Attic insulation stores up the day’s heat and can increase the temperature of your interior ceilings to as much as 110 degrees.
Not Just a Summer Issue
It’s still important to vent the attic even in the Winter. Moisture from indoor activities will migrate from the living spaces to the attic. This can delaminate plywood, rot roof sheathing and framing or cause mold/mildew to grow.

Having adequate attic ventilation year round is important to the long-term health of your home, optimum interior comfort, and reduced heating and cooling costs.
