Soffit Question

burnt03

Used to have a cedar shake roof, lower ventilation consisted of 1" holes cut into cedar planks where soffits go (what's the proper term?).

They sheeted the roof, installed asphalt shingles with a ridge vent and alum. soffits. Took a look under the soffits, they cut a strip (roughly 2-4" wide) on the outside edge of the cedar planking prior to putting the soffits up. They also stuck 4" pipe to run from the soffit intake, into the attic (sort of a baffle I guess).

Is that 2-4" strip enough to provide the ventilation if they only had 1" holes cut before?

Take a picture and post it here so we can see the soffit vent holes in the aluminum, please.

Hard to tell without the brand name.... Maybe someone else is familiar with your brand? They range from 10-19 NFVA per lin.ft. The good thing is the elevated 3/4" which is better than only elevated 1/2". You will get full air to the slot they cut, ask them for the manufacturer's name, look at their website for the NFVA and do the math: http://www.airvent.com/homeowner/pro...it-specs.shtml
