Hello_there

I have the same problem with a different setup. Half finished walls. Nothing up except the roof. No insulation on walls or ceilings. 15 degrees hotter than outside.
Lack of insulation on roof and vents that are kind of blocked by the finished walls is my issue.
Solutions I’ve thought about are putting a vent up high, by the ^ of the roof. Putting a fan near that. Stapling insulation to the joists, just under roof, to keep some of that heat out.

Out of left field solution: get a heat pump water heater. It will be a lil loud tho.

Fasten the key to the inside of the backpack in a way that doesn’t come off. Kid is going to have their backpack.

Uhh… is it legit to just cut thru beams to put in piping? Over half of those beams are cut thru. I’d ask about that as well. I can’t tell where this is, but if the plumber cut thru load bearing beams to put in plumbing that might be an expensive fix.

This reminds me of a college rivalry. People from College A (mine) hated College B. People from College B didn’t care at all.
