Continuous Attic Ventilation

Continuous ventilation helps to reduce cooling costs validates the warranties of some asphalt shingles reduces heating costs in colder climates reduces chances of moisture buildup in attics etc.

Continuous attic ventilation.

Good ventilation allows the heat and moisture to escape. Moisture in the attic can cause mold to grow and the wood can rot so air circulation is very important. Lowering the temperature in the attic can help reduce air conditioning energy costs and roof deck temperature optimize the service life of a roof covering and minimize ice damming. They re most effective when used in conjunction with a continuous ridge vent.

So a house with a 1 500 sq ft. They are easy to install under the roof s overhang which is known as the soffit are generally hidden from sight and provide excellent protection from weather outdoor debris and pests while still allowing air to flow into the attic. These vents allow outside air to enter the attic at the lowest point of the roof along the underside of the eave. Continuous or individual soffits soffit vents are one of the most popular intake vent styles.

Intake vents located at the lowest part of the roof under the eaves allow cool. There are lots of other reasons why ventilation is important. Effective attic ventilation systems reduce damaging heat and moisture in your attic promote energy efficiency by helping to reduce the load on your air conditioner in the summer and also reduce the risk of ice dam formation on your roof. Continuous ridge vents are more effective because they are installed at the peak of a roof s ridge allowing for warm air to escape from the attic.

In some circumstances you can have less but we recommend the 1 150 ratio. Look for the nfva of each vent you buy stamped somewhere on the metal. That cuts cooling costs and prolongs shingle life. In the summer good attic ventilation reduces heat buildup.

Of venting ideally about half placed high on the roof and half in the soffits. In the winter warm moist air seeps into the attic from the living space below. It has the ability to work with vaulted ceilings and you only need one of them to get the job done for ventilation as compared to multiple box vents. A new roof is more than just shingles.

This is one of the reasons continuous attic ventilation is so important. It also works better because it creates a vacuum. Soffit vents come in several sizes and styles including small round discs and rectangular grilles. Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.

Attic ventilation serves two main functions. Continuous ventilation systems with ridge and soffit vents keep attics dry. Learn how to plan a continuous ridge and soffit ventilation system for your attic and how to install soffit vents and other attic venting systems.
