To vent or not to vent.

[Robert Jones]

This home has been remodeled and a new roof installed. The second floor is finished with vaulted ceilings. My question is, should there be some kind of venting at the ridge? There's no real cavity but, I am still thinking that some kind of venting should have been installed. The home was originally built in 1927. Opinions please.

Yes, I think it was a mistake not to install roof vents near the ridge or a ridge vent. It's not a simple uninsulated attic anymore, and the cedar shingles on strapping have been replaced with solid sheathing. A good roofer would have known it needs venting.

Did you find access to the cavity behind those kneewalls? I would look in there for insulation. Good places to find vermiculite, rat poop, live K&T, wasp nests and so on.

I'm not saying it is, but that could have been a Sears kit house, although I just searched a couple of websites and didn't find that particular design. I like those old houses, but the work is never done on them, it seems.

Sure. When the new roof went on, it should have been installed to meet the current requirements and/or the shingle manufacturer's instructions. Ventilation is required for enclosed rafter spaces.

I like the bedroom EER&O window.

Thanks guys. John there was zero cavity access in the home. The second floor used almost all of the space for making a livable room. The wiring has been completely updated, all grounded outlets etc...

Bill, what is EER&O?

[Brandon Whitmore]

Yes, venting is most likely needed depending on how it was insulated. (almost always required)

Thanks Brandon. Have never heard that specific term before.
