How does a metal roof vent?

Ventilation Basics
Hot air beneath the metal needs an escape route near the top of the roof and intake vents at the bottom of the roof. As long as nothing blocks the airflow between the intake and exit vents, the air will rise and exit through the escape vents, creating a continuous natural draft.

Is it recommended to insulate under metal roof?

The best material for use with metal roof insulation is in the form of foam batting. This foam can be used on either the outside or the inside of the sheathing. You will want to use this over rolled up or spray insulation because of the way that it lays flat and it can be easily installed under the metal roofing.

Do ridge vents really work?

Most effective ventilation uses a ridge-and-soffit continuous ventilation system, but even these designs can vary from roof to roof.

How do you calculate shingles for a ridge cap?

To estimate roofing materials, start by finding the total square footage of the roof and divide the number by 100 to determine the number of "squares" in the roof. Since it takes 3 bundles of shingles to cover a square, plan to purchase 3 bundles for each square. Then, add 10% to the number to account for waste.

Do you need ridge cap shingles?

Some roofers will cut shingles into pieces and use these pieces for the hip and ridge cap, regardless of which shingle is being used on the roof. The thicker Cambridge shingles are not designed for ridge caps. They do not lay flat and some may crack or break when you bent them over the ridges.
