Attic Ventilation
With the installation of your new roof, we will replace or install attic vents to prevent moisture. Moisture is the number one enemy of buildings. Warm air can cause condensation, increasing the humidity in the attic. Attic venting codes are primarily designed for moisture removal, not superheated air in a hot climate.
Heat and moisture accumulate in every attic at all times during the year. Proper ventilation of an attic preserves the structural integrity of the roof. When left uncontrolled, excess heat and moisture can significantly damage the roof and structure, reducing normal life expectancy. Proper ventilation validates most shingle manufacturers’ warranty and protects the investment in your home.
attic ventilation techniques
There are three types of commonly used attic ventilation techniques. The two passive types are dormer vents and continuous ridge vents.
- Dormer vents are the age-old standard because they work very well. They are low profile, galvanized steel construction and vent common attic spaces very efficiently.
- Continuous ridge vent is more effective in venting sloped or vaulted ceiling areas.
- Forced air (thermostat controlled) attic fans move and evacuate large volumes of air for maximum venting. They usually require separate wiring in the attic.
No matter what type works best for you, attic ventilation is essential in protecting your home and making it more comfortable while lowering energy costs.
