QUICK FACT: Attics must be ventilated to relieve heat buildup caused by the sun. If necessary, improve airflow by adding or enlarging vents.
Remember what we said last week about making sure you have more than enough roof and soffit vents to extend your shingle life in the hot summer sun?
In the winter, if you find that your attic has dampness or frost–you need better ventilation! Roof vents do not mean you're letting warm air out of your home when you are trying to keep it in. It's usually a lack of proper insulation that leads to that, so make sure your attic is ventilated properly.
