Quick Answer

They lower the temperature in the attic to reduce heat infiltration when temperatures are hot and prevent refreezing of melted snow to form ice dams.

Heat and moisture can cause damage to attics and roofing. During the hottest months of the year, attic temperatures sometimes reach 160 degrees Fahrenheit in homes with inadequate attic ventilation. This heat radiates back through the ceiling of the home and increases cooling costs by up to 30 percent. Solar attic vents help to expel hot air from the attic and replace it with cooler air from the outside.

Moisture from normal household activities such as showering or cooking collects in the attic. The damp air encourages the growth of mold and mildew in the warm space. With proper ventilation, the moisture exits the attic to prevent these problems.

Some solar attic vents have optional thermostats. These thermostats engage the vent when temperatures reach the set temperature and disengage it when the temperature falls below a setting several degrees lower. In order for the fan to begin turning again, the attic temperature must reach the upper limit. Such thermostats help to prevent heat loss when the home heating system is in use.
