Ventilation – Why is ventilation important?

Proper attic ventilation is required by the building code and by the shingle manufacturers to meet their warranty requirements. In theory the air in your attic should be the same temperature as the outdoor air. Ventilation allows warm air to exhaust allowing your attic to stay cooler in the summer months. There are many varying opinions as to the effectiveness of attic ventilation in respect to it’s function, especially in regards to the winter months. Every home is unique and the requirements may vary from home to home. A trained contractor should be able to advice you on your needs.

Please see Ventilation under Industry topics for additional information.
