Even in attics that are fully insulated to the U.S. Department of Energy's recommended R value, the space can easily reach temperatures of greater than 120 degrees Fahrenheit when the outside temperature is only 85 degrees. This difference comes about due to the absorption of heat energy through the roofing material along with an insufficient amount of ventilation to move the hot air back out. To help homeowners achieve a greater level of comfort and lower home cooling costs, experienced Fort Worth roofing experts can install an energy efficient solar ventilation system.

Ventilation is important not only to the comfort of everyone living within the house, but also to the roof's lifespan. A roofing system that is blasted by heat from the underside may experience problems that include bubbling or curling of the shingles, popped fasteners and warping of the sheathing, joists and rafters. Extreme heat in attics can also cause the home's air conditioning system to work on overdrive, leading to excessively high cooling costs.

The chimney effect, which is a casual name given to the process of natural ventilation within the attic space, is the most common and least expensive kind of ventilating that a home can have. This movement of air depends upon a large difference in temperature between the outdoor and outdoor air.

To augment the home's ventilating capabilities, roofers can install a solar vent onto the home's rooftop.

Solar attic vents are fans mounted onto the roof's exterior. The opening for the fan is made by cutting a hole through all the layers of roofing material. Located at the peak of the roof, the fan is exposed to ultraviolet light even on cloudy days. This powers the photovoltaic cells, which allow the fan's motor to charge. The motor is then able to propel the fan's blades. Next, hot air is pushed out of the attic. The fan moves at its greatest rate of speed during the peak heating of the day but will operate from sunrise until sunset.

Roofers can connect the fan to the home's programmable thermostat system. This allows the fan to be activated only when the attic's temperature reaches a point set by the homeowner. If too much condensation develops in the attic when temperatures are below the set point, the property owners can use the thermostat to turn on the fan as needed. Although these solar powered fans cost more upfront to install, they have a rapid payback time due to not using any electricity to operate.
