Attic Ventilation Saves Energy & Money
Installing proper ventilation in your attic is the most vital step you can take to increase the longevity of your roof.
Poor ventilation will vastly shorten the life of roofing materials. Daily, we see roof systems expire early due to either inadequate ventilation or no ventilation at all. Proper attic ventilation will not only extend the life of a roof but it will help reduce problems as it helps balance, or minimize the temperature differential between the air in the attic and the air outside. Simply stated; proper roof ventilation removes damaging heat and moisture from attic areas. It is key to an energy efficient, healthy home. While your home needs to be sealed tightly to reduce heating and cooling costs, it also needs to have adequate airflow, to prevent moisture accumulation and provide adequate fresh air within your home.

Common problems of a poorly vented roof:
Summertime Energy Costs
In the summer heat buildup in the attic can lead to the transfer of heat back into the home. When heat transfers back into the home in the summertime it will raise energy costs by putting a load on the AC unit reducing energy efficiency. Heat buildup also encourages premature aging and cracking of roofing materials.
Wintertime Ice Dams
Ice dams occur when the heat from your home gets trapped in the attic consequently warming the roofs decking causing the snow to start melting from the bottom. Since heat rises, this melting will generally start at the ridge of the roof causing water to run down to the gutters and eaves. Once the water hits a cold gutter and eaves it refreezes. The ice eventually backs up under the roofing system or behind a fascia board where it melts again, ultimately soaking your walls and ceiling while destroying everything in its path.
Trapped moisture causes condensation. Condensation that forms inside an attic comes from the use of tubs, showers, washing machines, clothes dryers, dishwashers and boiling water. Moisture causes mold, mildew, and fungi. All this leads to dry rot, which spreads and damages any lumber that is affected. Condensation also causes rust; any non-coated metal will rust over time and eventually deteriorate to the point of failure.-
Go Green with Proper Ventilation
While in some cases the combination of soffit vents and continuous ridge vents may be adequate, many times additional venting is needed. There is a variety of attic fan options that you can consider that will help draw air out of your attic space. Some are controlled by a switch or thermostat that can detect heat build-up. Many solar-powered vents qualify for a 30% federal tax credit.
