subject: Roof Ventilation [print this page] The ventilation of the roof in your home is very important because if the house is not well ventilated there will be moisture problems in the future.
An efficient ventilation system balance out temperatures on both sides of the roof, which helps keep your house cooler in the summer and prevents ice dams along the roof eaves in cold climates. Sufficient airflow prevents heat buildup in your attic, and it helps protect your roof from damage caused by condensation or ice. A typical ventilation system has vents in the soffits to let air intake, which flows upward beneath the roof sheathing and exits trough the roof vents.
One strategy for increasing roof ventilation is to add more of the existing types of vents. Or, if your are reroofing , consider replacing all of your roof vents with a continuous ridge vent. If you will like to increase intake ventilation consider adding more soffit vents. If you decide to replace the soffits with aluminum soffits, install vented soffit panels that allow air intakes.
There are 6 major types of vents for your home. Here is a list of the those 6 vents:
1.Soffit vents can be added to increase airflow into attics on houses with a closed soffit system.
2.Continuous Soffit Vents provide even airflow into attics. They are usually installed during new construction, but they can be added as retrofits to unvented soffit panels.
3.Roof vents can be added near the ridge line when you need to increase outtake ventilation. Fixed roof vents are easy to install and have no mechanical parts that can be break down.
4.Vented soffit panels are used with aluminum soffits to allow airflow along the eaves.
5.Gable and dormer vents generally are installed to increase ventilation. The vents come in a variety of styles and colors to match the siding.
6.Continuous ridge vents create an even outtake airflow because they span the entire roof ridge. This type of ventilation is barely noticeable from the ground. They can be added at any time, during or after, of the roof reinstall .
Is very important that you consult your roofing contractor and ask him what is the best option for your house. The ventilation of the roof can depend on the area where were you leave and that can affect the ventilation you want to install. You roofer will be the best person to ask but you can always do your research before you talk to him.
