Metal Roof Attic Ventilation

In a hot climate roof vents expel hot air from the roof or attic while relieving the load on the air conditioning system.

Metal roof attic ventilation.

Ridge vents are installed at the ridgeline of the roof. Ridge vents are an effective way to achieve proper attic ventilation and are becoming a popular option for metal roofs. They run continuously along the entire length of the roof so hot moist air is continuously released from the attic space across the entire ridge. Selecting metal roof and wall panels is a strategic investment for the life of a building.

It also vents out the moisture which migrates from inside the home to the attic. For existing homes in condensation prone climates with ventilation that does not come anywhere close to meeting code standards a metal roof can become the straw that breaks the camel s back by decreasing the roof deck temperature just enough that dewpoint is reached in the attic causing condensation to occur where it has not occurred before. In winter good ventilation helps to avoid ice dams on your roof. Optimal air movement not only promotes temperature regulation and energy efficiency but also reduces the risk of moisture related issues like condensation build up.

The building codes and building science for natural roof ventilation however only appeared in the 1940s. Roof ventilation depends on the simple scientific fact that hot air rises. It is compatible with 3 or 4 ductwork and includes a 3 to 4 adapter for convenience.

Roof ventilation in a cold climate vents moisture and ensures a cold roof temperature to avoid ice dams.
