In both winter and summer, good attic ventilation can save you bundles on energy costs. In summer, ventilation reduces heat buildup, which prolongs the life of your shingles and cuts cooling costs. In winter, good ventilation allows the warm, moist air that seeps from the living space into the attic to escape, keeping your attic safe and dry. But how do you know if your attic is properly ventilated?
The following tips provide a checklist for adequate roof ventilation:
Once you have established a need for improved ventilation, look at the best location for new vents. Roof vents near the roof’s peak and soffit vents under the eaves produce the best results. This arrangement encourages air flow through the soffit vents and out the roof vents. How many vents will you need? Your exact number is best determined by measuring your attic area. Multiply the length by the width to gage square footage. Most attics require 1 square foot of vent opening per 150 square feet of attic space. While building codes often allow you to reduce this number by half occasionally, more ventilation is usually best.
Proper roof ventilation plays an essential role in maintaining a comfortable and healthy climate in your home, as well as affordable heating and cooling costs. By taking the time to discover how effective your current attic ventilation is, you can determine whether or not to move forward with vent updates and installations.
