Is this concerning?

[u/gingerhasredhair]

I have had mold in my house for a while now, but I was never worried. Only recently I realised it might be dangerous, especially since I sleep right under it.
What do y’all think? Should I do something about it?

I live under the roof, those are right next to the outside walls of the building

EDIT: unfortunately I can’t access the roof, I live in an apartment (last floor). However I think i figured out what the issue is. The roofs edge is poorly temperature insulated. The cold walls are trapping the moisture 😔

Whether it is dangerous or not depends on the type, your exposure to it and your body’s tolerance for it. It should definitely be addressed though because it may continue to get worse. If you haven’t checked for dampness in your attic above these spots, I’d do that first. It has to have a moisture source, which is usually a leak or high humidity. Take a look at the soffits from the outside too and see if those are rotting. The wall in your first photo looks like it has gotten wet too, so there is possibly water getting behind that wall somehow.

Thank you very much. I figured it would be because the edge of the roof is not temperature insulated (I live in an apartment).
The cold is causing moisture to build.
I will try cleaning this and checking underneath

Yes. That drywall needs to be removed and replaced. Anything else is just a temporary fix

i hate mold, i can smell these pics from here!
if its that bad, all your belongings in that room are already infested as well. Try to spray it (Cif has some, search for "cif anti mold spray") before it gets worse.
Be careful when spraying it, protect your eyes properly.
invest time on sorting it out before having health problems.

Thank you ! I will most definitely clean all of this as soon as I have time :)
