What Homeowners Should Know About Attic Ventilation


1) Attic Ventilation is Essential

Did you know?   

The average family of four generates 2 to 4 gallons of water vapor a day through activities such as cooking, cleaning, showering, laundry and breathing.  Some of this water vapor rises into your attic.  Ventilation helps remove it before it causes problems such as wood rot, wet insulation, mold and mildew.

2) Your Attic Needs Equal Intake and Exhaust Ventilation

Did you know? 

An easy way to ensure that your attic ventilation system is balanced is by using Air Vent's Edge Vent for intake and ShingleVent 2 ridge vent for exhaust.  Together they are part of The Balanced System for Optimum Attic Ventilation. 

3) Ridge Vents Are the Most Efficient Exhaust Vent for Your Attic

Did you know? 

When using an electric-powered attic fan be sure the fan has a thermostat to fight heat in the summer and a humidistat to fight moisture in the winter.  Without a humidistat the power fan will only ventilate your attic as the heat builds up.  It won't fight moisture buildup.

4) Mixing Two Different Exhaust Vents on Your House Is a Mistake

Did you know? 

Homes with very little or no horizontal ridge length are still candidates for ridge vents.  Air Vent's Hip Ridge Vent is designed for use on the diagonal hips - offering another option besides power fans for hip roofs. 

5) Your Roofline Will Look Best if Ridge Vents Are Installed End-to-End

Did you know? 

Indications that your attic might have a ventilation problem include wet or compressed insulation, rusty nails or rust spots that dripped onto your insulation, blackened plywood, mold or mildew inside your attic, curling or cracking shingles, uneven snow melt, and icicles at the roof edge.
