The purpose of attic ventilation is to create a balance between a well-insulated space and a well-ventilated space. This applies to both winter and summer seasons, even though weather dynamics might seem completely opposing.
Attic ventilation addresses the natural principle that warm air rises. In a typical attic and roof cavity, various types of installed vents allow that warm air to escape. What many homeowners don’t know is that a certain number of vents is required per square foot of roofing area.
Attic ventilation allows trapped air to be released from the attic and roof. This is achieved by installing a combination of air vents that permit air circulation throughout the year. Ideally, a professional would recommend the type and number of vents for optimum air ventilation.
Adequate ventilation is also important for another reason – better control of air moisture. Moisture buildup in the attic and roof is quite common in winter and summer, and excessive moisture can cause numerous problems. The remedy is to properly ventilate the space from end to end.
Inadequate attic ventilation can cause various problems. For one, overly moist attic insulation can lose its effectiveness. As well, your HVAC system (heating and cooling) may have to work harder in winter and summer. Worse still, excessive attic moisture may promote mold growth.
In winter, a poorly ventilated attic may cause ice to form on the roof edge and result in a problem known as "ice damming." This can damage roof shingles and even compromise some structural components. Finally, too much air moisture in the attic can result in severe rust and corrosion.
In determining the need for ventilation upgrades, it’s wise to have a professional attic inspection. And while a DIY inspection might save some money in the short term, nothing compares with a comprehensive assessment from a professional who has the experience and expertise.
Inside and outside the attic, an in-depth assessment can identify all types of deficiencies – from ventilation to insulation to structural. As such, various remedies can be recommended to optimize performance. Here again, a professional approach to repairs and retrofits is preferred.
