What To Know About Roof Ventilation


What To Know About Roof Ventilation

Roof ventilation is essential for homes – whether you live in a hot or cold climate. Roof ventilation functions differently in hot and cold climates. For a cold climate, roof ventilation is necessary to prevent the buildup of ice dams which are accumulated from melting snow. Roof ventilation will also help water build up due to condensation which will result to rotting, mildew and molds. During the summer, roof ventilation will help expel extremely hot air which usually creates the furnace effect, making the attic or the rooms on the top floor unbearably hot.

Benefits of Roof Ventilation

Kinds of Roof Ventilation

The kind of roof ventilation you need may vary from home to home. Each home is designed a different way. Additionally, you must also consider the climate and weather conditions that you normally experience.

  1. Intake Vents

Intake vents allow outside air and they are located along the lowest eave of a roof’s assembly.

Types of Intake Vents

  • Individual Soffit Vents – Vent grates that are spaced evenly on eaves.
  • Continuous Soffit Vents – Allows ventilation along eaves and are installed on the soffit or eaves.
  • Drip Edge Vents or Eave Vents – A type of venting with a drip edge which is used to provide intake ventilation.
  • Undereave Vents- Intake vents are installed at the under eaves of roofs.
  1. Exhaust Vents

Exhaust vents are installed on roofs to expel hot air from inside your homes.

Types of Exhaust Vents

  • Static Vents – Type of exhaust vent installed over a hole on your roof. It has no moving parts.
  • Ridge Vents – Exhaust vents installed from end to end of a roof spanning its entire length.
  • Gable-end Vents – Installed at the gable ends of a roof. They are more effective when there is sufficient wind.
  • Turbine Vents – Installed at the top of roofs and utilizes wind power to expel hot air from inside the house.
  • Powered Vents – Exhaust fans are installed on the roof and mounted near the ridges of the roof.
