Do metal roofs have ridge vents?
Ridge vents are the most popular option for metal roofs and are an effective way to achieve proper attic ventilation. Ridge vents are installed at the ridgeline of the roof and run continuously along the entire span of the roof.
How does a metal ridge vent work?
A ridge vent is usually made from aluminum or a mesh-type material and is installed underneath the final layer of shingles to create airflow across the exterior roof. It draws hot, moist attic air out through the ridge vent and pulls fresh air into the attic through the soffit vents.
What are the different types of ridge vents?
There are two primary types of ridge vents: shingle-over vents and aluminum vents. A shingle-over vent is installed over the ridge of a roof and is covered over by asphalt shingle caps that match the surrounding roof shingles.
Are ridge vents a good idea?
The truth is, most experts agree that though other roof vents allow some ventilation (which is better than none), ridge vents are the most efficient and cost-effective roof ventilation system around. Our recommendation is yes. Especially if you are installing a new roof, you want to extend its life as long as possible.
Which ridge vent is best?
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. There are many good ridge vents on the market, and the continuous vent, as opposed to the individual roof vent, is the most effective.
What is the advantage of a metal roof covering?
