No matter the conditions, we have ventilation systems perfect for keeping your air flow balanced. Our roofing and ventilation experts can help find which type and model will work best for your existing ventilation situation.

Solar Vents vs Electric Vents

When researching roof vents, homeowners have a choice. Electric vents and solar vents pave the way for new, long-lasting roof ventilation systems. There are many advantages to these types of ventilation systems and choices! One can even choose to have a solar-powered skylight that is integrated with a rain sensor. There are so many options it would be difficult to choose between a solar powered or electric powered system!

Solar Vents vs Electric Vents: With attic ventilation, the hot, sluggish, old air is removed and replaced with clean, fresh air from outside that in turn, can assist in cooling your home. Until very recently, electric powered vents or fans were the number one product for this issue of stagnant air. However, since solar power became readily available, it has been used more in the consumer marketplace.

Using an electric ventilation system, one can constantly have a source of fresh air just by hooking up a fan. The downside is that there is a dramatic cost in doing so. The electricity involved in running a fan may cost upward of two hundred dollars per year, adding to your carbon footprint. With the significant additions to your overall budget and environmental pollution, are dubbed side effects, can result in a deterrent for this type of system.

On the other hand, solar-powered ventilation systems are the new alternative to original electric vent systems. These greener systems remove heat and more importantly, moisture from your attic area, in turn keeping your home cooler. This also may increase the investment and worth of your home, while running only on free energy from the sun. Once this system is installed, the solar vent will provide cool air during the day, just like electric vents, but cost nothing to operate and leave no carbon footprint.

Electric Vents


In installing an electric vent/fan, your home is provided with a constant cooling effect. The electricity does not depend on the sun’s rays for availability. The spinning action of the electric fan system expands the air more easily and quickly throughout your home. Solar vents, on the other hand, are dependent on sunlight. Electric ventilation systems also cost less for installation than the solar systems.


If you are environmentally conscious, it is not a good idea to purchase an electric system. Its carbon emissions during run-time add to the Earth’s pollution and to global warming. If you consider yourself ‘green’, do not install an electric vent system. The cost of running such a system, in addition, is large. During the summer months, you may have to pay more for increased fan usage in order to cool your home. Because this type of system involves wiring, updates, and routine checks, calls to a technician or professional are inevitable to ensure safety.
