Inspections for Attic Ventilation

Proper attic ventilation home inspections

The reason a professional home inspector is hired when you purchase a home or just have concerns regarding your existing home are many. Attic ventilation is just one concern your home inspector can address.

 

More than a handful of time, I have inspected homes with fairly new roofs, ridge venting is installed on the exterior of the roof, but when I get into the attic, I come to find that the roofer never cut holes in the roof sheathing to allow the ridge venting to serve any purpose.

 

Again, the purpose of venting is to allow for a uniform air flow along the underside of the roof.  When additional ventilation is present such as box vents or power fans, the uniform air flow can be interrupted creating hot spots in the roof.  Under certain conditions, these extra vents can even allow hot air to enter the attic through the ridge venting.  The overall roof and attic ventilation can be effectively lowered and, as previously stated, can altogether void the shingle manufacturer’s warranty.

Improper venting in the attic space can lead to issues with mold and mildew. Moisture is the perfect breeding environment for mold. If improperly vented a bathroom vent can channel that warm moist air into your attic where it will collect and over time create that perfect environment.

 

The purpose of proper attic/roof ventilation is to allow cool air to enter the attic at the soffits, rise uniformly up the underside of the roof sheathing, and exit at the ridge venting.  In perfect ventilation conditions, the attic’s air temperature should essentially match that of the exterior air temperature.  Proper insulation on the attic floor helps keep the living space comfortable.

 

Hiring a professional experienced home inspection company can help identify these issues before they become hazardous breeding grounds for mold.
