Why should I use ridge vent with my metal roof?
February 7, 2012
Why should I use a ridge vent? I’ll bet you think you asked a simple question but you didn’t. Let’s start at the top. Ridge venting is a continuous vent strip that is installed at the very peak of the roof. It requires a two to three inch opening to be cut across the very peak of the roof, exposing the attic below. The ridge vent straddles that opening. The ridge vent is only half of the venting system if that’s the venting system you’re going to use.A ridge vent needs a continuous air supply from the bottom of the roof edge on both sides of the roof to work-- often called soffit vents. The way this very simple, yet state-of-the-art system works is air enters the attic at the lower soffit vent and using the heat of the sun as an accelerator, moving air up under the roof deck, washing the underside of the roof with fresh air, somewhat continuously. It’s called a cold roof because the intent is for the temperature of the roof to be close to or equal to the temperature of the outside air. Here are five solid reasons to be sure you use our Flex-O-Vent product in your new metal roofing system:
- Allows outside air to flow naturally upward and out of attic.
- Promotes a cooler, drier attic.
- Helps prevent moisture from becoming trapped in insulation, structural wood, shingles and roof deck.
- Helps prevent rotting, mildew, drywall damage, peeling paint, and warped siding.
- Provides year-round performance for consistent ventilation without energy consumption
