Continuous Attic Ventilation

These vents allow outside air to enter the attic at the lowest point of the roof along the underside of the eave.

Continuous attic ventilation.

In the summer good attic ventilation reduces heat buildup. Trust me continuous attic ventilation is the only way to go. Moisture in the attic can cause mold to grow and the wood can rot so air circulation is very important. So a house with a 1 500 sq ft.

In some circumstances you can have less but we recommend the 1 150 ratio. Of venting ideally about half placed high on the roof and half in the soffits. A new roof is more than just shingles. 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.

To lower attic temperatures and to remove excess moisture. It also works better because it creates a vacuum. Attic ventilation serves two main functions. That cuts cooling costs and prolongs shingle life.

Continuous ventilation systems with ridge and soffit vents keep attics dry. They re most effective when used in conjunction with a continuous ridge vent. 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. Look for the nfva of each vent you buy stamped somewhere on the metal.

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. In the winter warm moist air seeps into the attic from the living space below. Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. 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.

Intake vents located at the lowest part of the roof under the eaves allow cool. Continuous or individual soffits soffit vents are one of the most popular intake vent styles. Soffit vents come in several sizes and styles including small round discs and rectangular grilles. There are lots of other reasons why ventilation is 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. This is one of the reasons continuous attic ventilation is so important. Good ventilation allows the heat and moisture to escape.
