Hi everyone, upon discovering that my cockloft has no insulation I’ve been on a journey to understand the implications of having blown in fiberglass insulation done. I’m having a very hard time finding someone that will give me advice in this situation and not try to sell me something.

The home is in Queens built 1931 and is a rowhome. It does not look like there is any ventilation in the cockloft at all (nothing on the roof, no vents anywhere). I understand that ventilation will help with moisture and that’s the last thing I want up there, but am I missing something? Does the brick in the cockloft handle the ventilation / moisture issue or do I for sure need to install roof / wall ventilation in the space. Do I even need ventilation?

I’ve also read the article on here “Insulating Low-Slope Residential Roofs” and honestly my take away from it is that
1. If I do insulate the cockloft, significant effort needs to be put into proper ventilation.
2. I could insulate on top of the roof.
3. Don’t do anything, leave as is.

1. The roof. I see my neighbors have vents on their roofs. Additionally, I’m not sure what those existing things coming out of the front and rear center of the roof are.
2. Front of the roof
3. Back of the house / roof
4. Inside the cockloft
5. Inside the cockloft

Any advice would be helpful.
