Los Angeles Attic Ventilation

The roof ventilation system prevents your attic from getting too hot and humid. In Los Angeles, the sun is constantly beating down on your roof. The sunlight hitting your roof heats the air inside. The ventilation system allows hot air to escape and promotes cooler air to enter through a venting system.

Failure to vent out hot air, humidity rises, moisture levels rise, and mold growth is promoted. Furthermore, your roofing materials prematurely age because of the extreme heat. They’ll curl, blister, and crack from the extreme heat coming from your attic. It is also important to hire top attic ventilation contractors in LA to handle your HVAC system having a harder time cooling your house with hot air in your attic, heating up the rest of the house. 

The driving force of roof ventilation systems is convection. Convection is a process of heat transfer. Hot hair rises in altitude while cooler air takes its place below. As your roof is heated up by the sun, the air inside your attic does the same. With a properly functioning attic ventilation system, the hot air escapes through roof ridge vents.

As hot air escapes out of the top of the roof, cooler air takes its place through soffits. Soffits are the bottom of eaves, the section of the roof that hangs over the side of the house. The soffits have small holes for cooler air to be drawn inside. Cooler air will help the attic remain at an appropriate temperature and reduce humidity levels.

Sunlight isn’t the only mechanic to blame for your attic’s rising temperature. Daily activities throughout your home can also raise the temperature, such as baths, showers, cooking, and drying laundry. Your roof ventilation system is designed to handle all of these elements, which is why its proper operation is vital for your home’s health.
