Hello all... I'm a recent homeowner, and I have now noticed a problem area in the house. I know that my roof is on the old side and needs replacing (we may do this next summer). But for know I have a issue in a enclosed porch, luckily this problem is not in the Kitchen, bedroom, living room. The area are circled in the pics below, when it rains the inside get "very" damp. It' been very humid recently (here in NJ), and there is now what seems to be mold growing (a black substance that we have been cleaning up with a light bleach and water solution). What can anyone suggest, Can that "area" of roof be fixed and if so, that takes care of the outside part, but won't the mold keep coming back? I don't know how to keep that area free from moisture, There a many windows but like i said it's been very humid so I don't know if keeping the windows open will help.
