How to properly vent lower roofs?

In the middle of 2nd day of re-roof…

The 2 lower roofs, which share a small attic crawl space have what appears to be ample intake soffits on the front & sides but I’m trying to figure out the best way to vent outward from the near top without ruining aesthetics.

I’ve added 2 goose-necks to the back of the upper roof but I really don’t think that will look good in the front lower roofs. I’m considered trying to put some sort of “gable vent” on one or both ends but your thoughts & opinions would be greatly appreciated!

FWIW, this is stucco over concrete block in Dade county, Florida within 1/2 mile of ocean.

THANKS!

How about ridge vent? HA HA HEE HEE HO HO! :lol: Just kidding of course. But hey, the ruling out of the ridge vent leaves you the remaining options. No?

Turbines: Probably too large. Power Fan: May be a good option. Or what you suggested with the gable ends. ( You could put a fan in one end )

Why is there vents on the rake?

LOL Thanks, I’m actually thinking Solar Powered High Gable Fans on each end; one intake & one exhuast but only because the roofer basically said he did not want to put any type of hole on top of either lower roof.

That’s how the it was when I bought it…There are 3 vents total across the eave in the soffits…one to left of the bay window and 2 on the lower right roof.

How is the structure run?

DCI smart vent is pretty easy and makes sure it will work

Great idea and also this would require you to install a wall flashing onto your 2nd story stucco/block. If the attic space is closed off in between each truss (cathedral) on this lower roof than this is the only efficient solution I think.

If there is a true attic space you could install a 4 foot off ridge vent… maybe two balanced out for appearances.

Those rake vents cancel out the eave intakes and they need to be deleted. If that only leaves you 3 on the eave you may want to do an intake calculation based on this attic area and add more if needed. Intake should be at the lowest point, exhaust at the highest. None at mixed height levels if possible. Improper ventilation is a shingle warranty void er.

THANKS!
Preparing to have rake vents closed off & add a gable vent (non-powered & no fan) high up on both ends. Roofer recommends something no bigger than 12"x12" in aluminum with critter screen from big box stores. I’m thinking more a rectangle rather than a square. What else should a homeowner consider…Do they open & close? I would appreciate your thoughts & opinions especially as to type and material.

WoW is correct. Vents won’t work do to lack of cross ventilation which won’t work unless sleepers span the rafters creating a gap from rake to rake.
Vents will only vent a single rafter bay.

Thanks!
Not sure what sleepers are but …Yes there’s a gap from rake to rake as the 2 lower roofs share a small attic crawl space, if that’s what you mean.

I think you would be wise to do the vent calculation:

2 small exhaust vents do not sound like enough exhaust to me for what is pictured but hard to say. Be sure you have enough intake for the same area also.
