I’m getting conflicting information from my contractor and my home inspector on whether this is sufficient ventilation for my attic.
My attic is completely unfinished. It’s about 950 sq/ft total. It’s comprised of two parts: a larger attic with a steeper grade (30’ x 23’) and a smaller attic with a lower grade (12’ x 23’). The two are separated by a wall with a 2’ x 2’ hole cut through it. I have one gable vent on the smaller attic and four turtle vents up high on the larger attic (two on each slope).
Before, I had an additional gable vent on the east side of my house, but my contractor covered it up when they replaced my siding as part of an insurance claim. He said I did not need that gable vent. I do not (and cannot) have soffit vents.
My illustration isn’t to scale, but it gives an overview of what I have. Is this current setup sufficient ventilation?
