I need help identifying a longstanding problem in my house. I have had the ceiling paint on the second floor of my house peeling and recently it has become worse.

The peeling is happening in two bedrooms of the house, so it is not isolated to one spot. I thought it was due to poor attic ventilation since the soffits in my house were blocked when they built the house in the 1940s.

This spring I addressed the problem with massive new vents on top and bottom of the roof, but it isn't making problem better. Any clues as to what the problem could be?

Since your house is from the 40s I believe your problem lies with the plaster on the ceiling I recommend sanding it skim coating the whole ceiling with drywall compound or just as necessary and prime it with oil based primer it's a quick drying product that will cover almost any posture give it to coach if necessary then paint it flat white. Hope this helps you out

Did this in a few houses so what happen in this case the old walls were built with a smooth finish texture which oil base paint is the only paint to seal that texture so because water paint is applied to this texture after a time it would start peeling off so you have to clean it sheetrock 20,45 not compound because it takes to long to dry the more water the more peeling and you use a quick dry Matt primer then you paint

The paint was never done perpetuity in the first place is my best guess. I don't think they used primer abs back in the day they didn't have paint with primer.

It can be caused by water leak, smoke, a fire, being exposed to high humidity, or simply wear and tear from old age. The solution is always the same - peel it off and put on new one.
