| 1900 sf needs about 6.5 sf of vent area, evenly divided between intake and exhaust.
If you have 55ft of good ridge vent at about 18 sq in per foot, you have about 6.8 sf of exhaust.
Personally, I don't think I'd worry about it, but it's not a big deal to install some venting in the flow restricted areas. Pull off the existing cap, cut the shingles and roof decking, put on the vent and cap it. Prob less than an hours work.
We'll agree to disagree on the meaning of the quoted portion...lol.
I wouldn't get into it over specs of the contract, unless there is something that says "install ridge venting along full roof peak" or similar. Just express your concern about the restricted area's and ask that they put some venting in that area. __________________
