Experts, need some help please.
Our house is easily 40+ years old. On top floor, we have three rooms and a small lounge. In two of the rooms, the roof paint keeps falling off and recently black mold has started growing all over the roof of those two rooms.
What could be the reason? Has the lanter become porous to allow moisture to seep through? What are the options to fix this? Also why is this happening on roof of only two rooms?
Kindly note the problem is present even when there is no rain for a lot of days.
