Improving insulation for upstairs bedroom in cape

I recently bought my first house... it's a cape built in 1953 and located in Connecticut. One of the upstairs bedrooms has ceiling tiles which I plan to replace with drywall. The ceiling is vaulted with the sides at a 45 degree slope and the top is flat. I removed a few of the panels on the sloped part and saw there is a layer of rock wool insulation about 2.5 inches thick. It's the only thing between the roof of my house and the bedroom ceiling. The rock wool extends down to the knee walls where a previous owner covered it with cardboard (maybe to hold it up?). I did not see any baffles under the insulation to allow air movement. The house doesn't have soffits so I don't think I have any venting in this part of ceiling or knee walls. I believe the only venting is at the top above the flat part of the ceiling. There is a ridge at the top of the roof along with gable vents on each side of the house.

As with many older cape's, the temperature upstairs is always colder in the winter and hotter in the summer compared to the rest of the house. I'm not very knowledgable about insulation. Is what I have adequate or should I replace with a newer material? The insulation was made by Gold Bond and there is paper backing on both sides which I believe is a vapor barrier. The R value wasn't listed on the material. The ceiling will be down so if I should update the insulation this is the time!

Here's a picture of the bedroom ceiling:

Here's a picture where I removed a few of the tiles:

I appreciate any advice! I'm a newbie looking to learn!

Capes are always tough.

Any pictures of the home from the exterior?

Many times, if you are dropping the walls/ceiling already, foaming the roof is actually a pretty good option. Not the cheapest, but works well.
Oddly I don't have many pics of the exterior, lol. I'll have to take better ones this weekend. Here's three - the first I took when I had a tree cut down and the other two are from the MLS listing.


Side Note: You can't see the gable vent because of the tree branch but it's above the top window on the side facing the drive way.

If you want to vent it, I would create a vent channel via rigid foam.

Easiest thing to do would be to foam the roof if you are demo'ing all the interior drywall and tiles.
