Kitchen vent letting cold air in.

My kitchen vent pours cold air into the room. It's straight piped up through the attic and out the roof. I can't change the vent cover since it would tear up the roof shingles. Is there any type of damper I can splice into the pipe to stop the cold air? Or any other fix available?

A spring loaded backdraft damper in the duct might be just the thing.
It opens when the fan is on and closes when it's off.

Hope this helps.:)

Thanks, I'll give that a try.
