The Need for Proper Ventilation on a Roofing System

Attic ventilation is a requirement for every roofing system.  It allows excess moisture and heat to escape from the attic, where it would otherwise build up and result in mold, deterioration, and a host of problems. Properly installed, passive roof vents enable a home to “breathe.”  There are two general types of home ventilation: spot ventilation and whole-house approaches.  Both can be effective means of maintaining your home – here’s why:

Spot ventilation

Spot ventilation targets specific areas of your home to get rid of excessive moisture or temperatures.  One popular method includes installing an exhaust fan into a kitchen and bathroom. When vented outside, they can effectively remove moisture from the home. Make exhaust fans easy to use by wiring them to a switch or a dehumidistat control. A dehumidistat measures relative humidity levels and will automatically turn the fan on when needed.

Roof vents are another type of spot ventilation.  They are spaced strategically throughout the roofing system, and provide a great air exchange path when combined with ridge vents.

Whole-house ventilation

Houses are (or should be) designed and built to breathe on their own.  If a home is completed insulated with airtight products, it may be necessary to install an air exchange system to maintain a healthy balance.  Duct systems are available that mix outside air with the air that returns to the furnace.

An air-to-heat exchange system is a more expensive option that captures heat from the air being exhausted. However, this is a good option for maintaining comfort in homes without a central furnace.

Don’t go overboard on moisture control

Not all moisture is bad when it comes to being a homeowner.  Typically, summer heat brings high humidity levels that should be diminished.  In the winter, the danger is opposite, and steps may have to be taken to increase the amount of humidity in your home.

On average, humidity levels should between 20 percent and 40 percent. Extremely low or high humidity levels can cause health concerns (respiratory) and a plethora of home concerns, including static buildup, warped floors and trim, etc.
