The Purpose of Attic Ventilation

What’s the purpose of attic ventilation? It seems like a simple question,easy enough to answer. Unfortunately, all too often, that’s not the case. Most homeowners – and even some experienced builders and contractors – believe the purpose of attic ventilation is to remove heat that builds up in the summer.
This is accurate, of course. But what that answer leaves out is just as important as what it includes.
If you understand the principles of attic ventilation, you know an effective venting system provides year-round benefits.

• During warmer months, ventilation helps keep attics cool.
• During colder months, ventilation reduces moisture to help keep attics dry. It also helps prevent ice dams.
We can make that answer more specific – and more meaningful – by translating those functional descriptions into a list of benefits: Several purposes of an attic ventilation system are to provide added comfort, to help protect against damage to materials and structure, and to help reduce energy consumption – during all four seasons of the year.

Your goal should be to provide those benefits whenever you design and install a proper attic ventilation system.
