The house was a zero lot line variety where one side sat on the lot line and was about 1900 sq ft.
And to make matters more interesting, the bathroom and laundry room exhaust fan vent lines disappear into the insulation near the eves and there was no visible termination for those to be found anywhere. Possibly venting moist air down between the wall and the brick???
Doing a few back of the napkin calculations (yes I know that HI are not engineeres but I can't help myself) leads me to believe that about 1000 weep holes would be needed to provide the necessary ventilation area and there weren't over 200 weep holes around that house.
Anyone seen this before? Comments?
Thanks,
Ron
p.s. based on the houses on either side, it seems to be the standard practice for this builder in this development.

Ronald,
Did you look at the drip edge closely? Could it have been vented drip edge like this?
That particular brand kind of sticks out and I am not implying you can't see just that another brand may be better at stealth.

Ron; This is quite a unique design theory at such it is.
I would be curious to find out where this builder picked up this new design technology if that is possible. This design appears to violate every standard there is on moisture intrusion, and proper attic ventilation.
In all my years of building, I would have to say that nothing approaches this design evolution.
I guess if you called it out, you did what you had to do.
This Contractor, needs to be educated by someone if he still continues to build like this. (Where are the code officials for those areas?) Dunkin Donut? ha. ha.

I have to agree with Marcel on this. The baffles appear to be installed down flush with the roof sheathing not creating the “funnel” for the outside air to travel up the roof sheathing towards the ridge vent but of course w/o soffits vents it doesn’t matter because the ventilation system is only half there. The ridge vents are going to provide little ventilation w/o some source of outside air. Some heat will dissipate through but not very effectively. I usually find just the opposite, the ridge vents were installed without the roofing felt being removed over the ridge gap. Looks nice but pretty much useless. Also if there is no soffits the bathroom vent fans are pumping hot moisture laden air into the soffit cavity with no place to go. I thought it looked like extension cord too. I have seen the newer orange and yellow insulated cables but this just at first glance looked like extension cord.

Actually that is the line from the secondary drain pan under the AC and it does terminate properly over a window. At least there was one thing OK.
On the subject of inspectors for the town that his house was in: I ran into one while doing a final inspection on new construction. He said he had to do 40 houses a day! That's maybe 10-15 minutes per house.

Ditto everyones comments here Ron. Looks like some fool forgot the soffit vents and with the exhaust fan venting to the soffit, well, that’s not good.
I like all the duravent baffles in the rafter bays though. If you had soffit vents, they would work real good!  Usually they only put them into ever other rafter bay. Wow, they went the extra mile.

the soffit vents; for whatever reason they planned it that way. Other houses by the same builder were built the same way. I’d really like to talk to the designer and find out what his logic/engineering was behind these decisions. Ya never know, I just might learn something new.

Ronald,
I think you may just learn, all the intake air needed to keep the attic nice and cool in the summer or warm in the winter will be provided by all the gaps and holes in the building envelope.
Walking down memory lane to when I was growing up, the phrase, "Close that door, I don't want to heat/cool the whole state!", comes to mind.
