getting rid of soffit vents on one side of the house.
howdy, i live in the south and have a ventilated attic with a single powered fan. theres no hvac equipment in the attic and i recently installed baffles in every stud bay then spray foamed the entire top plate to completely air seal to hopefully prevent wind washing. very fun. well, baffles for two sides of the house.
theres around 230 feet of soffit in total and there are soffit vents every so many feet around the entirety of the home.
i was able to add baffles to every single stud bay along the green line, but the red lines are 110% inaccessible to install baffles. its a 10′ ceiling that is vaulted, and the soffits are only 8′ from the ground. not happening.
now if i were to remove/replace the soffits, i would have access to the top plates and i could spray foam them from that side, but i still couldn’t install baffles…
how important is that ventilation in reality?
i read this and it makes me feel like i would almost be okay if i blocked off the top plates with foam where the red lines are.
should i be concerned?
