Enough of COVID...what are you doing to the house?

On a hip roof, or with cathedral ceilings gable vents don't work and you may not have enough ridge to get enough ridge vent area. That leaves you with pagodas or conventional low profile square roof vents. One contractor wanted to put 22 square roof vents on my house. I cut him for bad design. The roof would have looked like it had chicken pox (and 22 places to leak). I went with three pagodas for main ventilation. Math said maybe two would work but it is a lot easier to seal one off than it is to add one if I don't like the airflow. Added ridge vents in some areas that wouldn't flow well to pagodas (gables with cathedral, garage attic that is mostly separate air space, etc.).

EDIT:
Did you have trouble with the mesh or rigid cobra vent? I stripped off the mesh (hadn't leaked) and added rigid (hasn't leaked in 1.5 years).

20 vents would be enough for a 7000sq, bungalow, or a 14000sq ' house! COBRA should work on any house with more than 2/12 slope as it would be impossible to have too little ridge. 1lf of ridge vents 100sq' of attic.

My problem was a west facing tide on a 4/12. Wind was occassionally driving rain thru the Cobra venting. Not overwhelming but bothersome.

Too many vents guy was putting them on almost every roof plane. He obviously wasnt doing math.

Hip roof plus steep pitch means not much ridge.

A 3000sq' 2 story needs 5 conventional 75sq" vents, OR 2 pagoda vents, OR 20 linear feet ridge for a Cobra type ridge vent.
 
I assembled..this. Matches the gazebo. Only 2 pieces missing that are trim bits and the company mailed them out today when I called them.

When's the next party? I'll bring my world famous baked beans (veggie style for your wife).

Love it! Where’s that from? I need something like that.
 
Oh Kevin you mothereffer….

Cleaning out the laundry in prep for the new hot water tank to see this on the wall…

Looks like efflorescence. Salts on the block from moisture, then "Kevin" painted over it.

Doesn't bond. Flakes off.

Wire brush.

I assume there’s no way to fix it outside of waterproofing the exterior?

It's not likely a major issue, efflorescence is caused by moisture trapped in the block reacting with salts that are in the raw materials (sand, limestone). Its generally just an esthetic problem, it does not always mean the basement is leaking.

In your pics there is no surrounding mold or drip marks so it's probably just related to a small amount of moisture that was absorbed into the blocks. That could have happened if a house isn't air-conditioned during a humid period. It's cause is likely poor preparation before painting, and the wrong selection of paint.

Solution is easy - a stiff wire brush will remove flaky paint and the fuzzy crystals. Following that you may want to neutralize the bad areas with a mild acid -- vinegar in a spray bottle works. If you want to paint it out (not really necessary - just for aesthetics), try Zisnner Watertite.

I have plenty of that in my basement just like that, painting the block walls is a dumb idea but lots of people do it (also to clean things up for a sale). Like others said it was painted over and now it is flaking off, likely efflorescence underneath the paint. You can clean it up but I would lose zero sleep over it if this area has no water on the floor. It is due to moisture in the block (if efflorescence) but is it worth a five figure bill to fix? I am sure you have already with other issues but just make sure water runoff and grade is manged outside.

I plan on striping the paint off an area as an experiment (will try multiple techniques) to see if I can just get it back to natural concrete.... and leave it that way in unfinished areas. I may acid stain the bare concrete as an experiment...

If you want a good esthetic fix, spray stucco does a nice job. It will absorb efflorescence for a long time, and it breathes so the moisture vapour passes freely through it.

Even if you hire a reputable company sometimes you get a loser crew. A nearby house had the roof done by a highly regarded company and they used pagoda style vents (sample pic below). Ok so far. It's a hip roof and they put one on the back plane and one on the side plane. Yuck but I've seen worse. Side plane one is not close to level. Looks terrible from the street. If it was my job and we missed it while up there, I would have put a ladder up again to fix it.

I just saw this on a house up the street from me. It was a knockdown rebuild, and they put that on the roof.
Has a little smile to myself.
 
Might be getting a deck. For the past 6-ish years of owning this place, the backyard has turned into a muddy shitshow and i've had to re-seed and then wait x weeks to get some grass again.

Well screw that. I'm getting a deck. My neighbour already gave us her offset umbrella (as she's getting a gazebo)
I'm all set to grill and smoke in all temps since i was already doing it without any type of cover ;)
Now just gotta get the cousin in-law to give us a date.....

my dogs kept churning up a patch of lawn at the bottom of the deck steps as they used it as a landing pad when doing superman impressions….after years and years of trying to repair it I said screw it and installed a patch of astroturf. I wish I’d “carpeted“ the whole garden now. The stuff is insanely expensive though.
