Your Fall Attic Ventilation Checklist

In order to help you ensure none of the above-mentioned problems will befall your home this cold season, we have written down the checklist professional home inspectors use for the evaluation of their clients’ attic ventilation.
• Balance: For a ventilation system to work properly, the intake and exhaust vents have to be balanced on a one-to-one scale. In a lot of homes, the intake vents are lacking in numbers. However, this is a problem easily solved by installing additional continuous intake vents to their system.
• Size Matters: Too small holes in the venting covers will lead to insufficient airflow, especially for larger spaces. Changing the venting cover to one with larger sized holes can make all the difference.
• Insulation Baffles: If you have a soffit vent installed, you will need matching baffles in order to prevent your vent from being blocked off and thus practically useless.
• Moisture: If you have been noticing that wooden structures around the home are warped or rotting, or if you have been fighting mold and mildew, then that is a clear sign that your ventilation system is failing you.
• Obstructions: Every other month, you should look into your vents to ensure that no debris, dirt, or other materials have gotten in to clog it up. Such obstructions can lead a drastic decrease in efficiency, or even render them completely useless. If you plan on painting a room with a vent soon, you should also ensure to protect it with painter’s tape or a small tarp. Covering it in paint will clog up the holes.
• Systems: Ensure that all your vents are using the same system. Vent systems aren’t made to be compatible with each other.
• Cathedral Ceilings: These ceilings require you to get up close and personal to check for problems or signs of malfunction.
