Why Is Roof Venting Needed

Vents ensure that a roof will be the same temperature as the air outside of it.

Why is roof venting needed. The need for roof ventilation wasn t documented until the early to mid 20th century. Hot air exhaust vents located at the peak of the roof allow hot air to escape. In a hot climate roof vents expel hot air from the roof or attic while relieving the load on the air conditioning system. The installation of roof vents is a crucial part of roof design because it allows for proper attic ventilation which may help prevent condensation and early aging of your roofing materials.

It channels the exhaust gases to the vent and helps maintain proper atmospheric pressure in the waste system. Some vents are necessary but you don t want to needlessly increase the number of roof penetrations. The vent stack is the pipe leading to the main roof vent. Ventilation is important because it extends the life of your roof reduces energy costs and reduces indoor temperature extremes.

Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic. Advantages of proper roofing ventilation. Take a look at the reasons behind roof ventilation the different types and if you need it. Roof ventilation in a cold climate vents moisture and ensures a cold roof temperature to avoid ice dams.

It can slowly rot out decking and your roofing materials even dripping down onto whatever is beneath it. In a roof that thin layer of condensation is a big problem. Table of contents show. Theory behind venting ice dams form when a home s escaping heat warms the roof sheathing and melts the underside of the snow layer on the roof.

Why is there a need for roof ventilation. Why plumbing air vents are important your home s plumbing system is designed to efficiently remove water and waste. An important part of a healthy home and a complete roofing system is roof vents. The intent of roof venting varies depending on climate but it is the same if you re venting the entire attic or if you re venting only the roof deck.

Roof vents create an additional roof penetration essentially another place of vulnerability where leaks can occur. Ventilation is the flow of air through a system of intake and exhaust.
