I really am not sure there is a product designed specifically for this but certainly providing intake to that area will be helpful. I would suggest contacting Cor-A-Vent to see if they have a solution for this.

Hello,
I have a few questions I have not found answers to while searching through the archives.
My plan is to cross batten over an existing rolled roof (4/12 pitch). The roof has sagged due to several rafters that cracked. I have fixed the rafters (from the inside) sistering new rafters to them. The roof is now stable.
I would like to shim the battens (shim the vertical battens, put down over old roof, centered over rafters) then lay the horizontal battens at 2’ OC.
I would like to keep the airspace open between the new metal roof and the old roof. Is this a bad idea? I was going to install a ridge vent so that there is airflow through the battens up to the ridge.
What is the best way to “screen” in the bottom edge of the roofline? Is there a metal screen or something like Cobra vent that I can use to keep bugs/ birds out?
Thanks for the help,
Pat

Do not use Cobra Vent. If you are doing it in metal, you can likely bend up a screened metal on the installers trim brake as well.
