When it comes to roof ventilation, homeowners have numerous options. Covered fixed roof vents prevent rain from seeping in, are easy to install and having no mechanical parts, quite easy to maintain. However, because they are generally not at the highest point of the roof, they may not facilitate removal of all of the hot air that can collect in the attic, and doing so would require several more vents than most homes have. Power vents, on the other hand, use a humidifier and thermostat to regulate the temperature and humidity of your attic by sucking the hot air out and pumping fresh air in. The drawback of power vents, however, is that they require maintenance, and at some point, will need to be replaced.
But homeowners have another, perhaps more promising option for roof ventilation. Roof ridge vents, unlike covered fixed vents or power vents span the entire gable roof ridge, creating a balanced ventilation system. Essentially, ridge vents use natural forces, such as wind blowing over your roof to create a negative pressure which then draws the hot air out of your attic. Air from the outside – which is cooler – then enters through the under eave vents, exiting at the ridge cap. And because of the natural convection action of rising warm air, ridge vents create and maintain a continuous air flow along the underside of the roof.
According to Jim Casper, an Energy Auditor, a continuous ridge vent is the # 1 cheapest, best, investment in your homes health and energy conservation. Jim writes, “Every day it allows the attic of your home to vent. In the summer warm air and even more important in the winter the moisture that used to build up in the insulation (and greatly reduce its effectiveness).” Additionally, ridge vents have no moving parts, require no maintenance or parts to repair or replace, and in most cases, enhance the look of your home.
So if you are thinking that a ridge vent might be the right choice for your home, the next step is to contact a licensed roofing contractor. As Casper notes, ensuring that a ridge vent works correctly requires expertise in just how to install a ridge vent system – including shutes and soffit vents – so that it not just improves your home’s energy efficiency, but also works to protect your roof.
