Re: To Baffle or Not to Baffle
how long is your ridge, if you have a chimney at the peak of a hip roof i can see him advising against ridge vent, but if you have a gable or mansard roof its not a big deal to have to runs of ridge vent
as for the amount of ventiation required, as per the canadian code you only need 1 sq ft of vented space for every 150 sq ft of ceiling space in of the attic.
if the bays between the rafters are blocked with 2x lumber its not a big deal if you can get in there and drill out some holes with a larger spade bit or a couple holes with a 2" hole saw
fire up the saw and make some dust
