Did a builder’s warranty inspection in a ritzy area. 8,200 SF home built bt a Realtor acting as a GC (Through her son).
The roof had a power vent fan, a short (about 10’) ridge vent (very complex roof) and, on the outside, 6 static roof vents. It turns out (after examination by a real good roofer friend of mine) that only one of the six roof vents had openings to the attic. Some guy just installed the roof vents but never bothered to actually cut through the roof deck to allow them to, like, actually vent!
About half of the soffit vents had baffles, but the blown in (fiberglass) insulation was actually blown into the baffles.
WHAT were they thinking?
