How do I vent Boxed Eaves????
Hey Roofing Pros,

Just bought a 1920's craftsman bungalow. I started removing the non-perforated soffit to replace with vented.

The dang eaves are closed off with boxing between the rafters. It does have a ridge vent, but without soffit vents.... this is useless.

What should I do ??

Thanks for the help.

I picture would help, but if by “boxing between the rafters” you mean a 2x4 block sitting on top of the wall and between the rafters you can “usually” create the airflow you need drilling the blocks.

How much drilling, how big of holes, and is that all you need to do? Can’t really say without more info.

How do I vent with boxed eaves
Hey Kwikfishron,

Thanks for the response. You are dead on.... it looks like a 2x6 between the rafters. Do you think this should only be one board thick, and I should drill with a hole saw and put in a vent?

Thanks a million.

Do you think this should only be one board thick?

It should be but you never know with old houses.

You need to get up there in the attic and see for yourself.

When you’re up there, snap a couple of pictures and post them here.

It sounds like an open cornice that's been closed in. There's likely insulation up against the back of that board if the house has been insulated much at all. Probably, your best option is to add venting through the roof.

To answer the board thickness question, it's probably only one board thick. Could be a 1x or it could be a 2x.
