Having Difficulty Finding Replacement Roof Vent Covers

I have to agree with enblethen,using this guide it seems to be the one,showing the outside and inside of vent lid.




If you haven't done this before Here is a short video that will help you.

You may need a new seal that goes on the metal edge this will make it a tight seal This is what you need


Replace like this

Also Maxxair covers are a great thing to have to make the vent lids last a lot longer,I replaced all my vent lids then covered them with the Maxxair covers 10 years ago and they are like new today.
