If it is warm and wet - mold could grow pretty quickly.

I would stress that the longer he waits to do repairs the worse damage will be- and you may end up with mold allergies and damaged property also.

I would call/write and set a deadline.

"gee mr home owner, I know that you have been busy with the recent rains, and are working hard to get to the growing list of complaints, and I am throwing mine onto the pile. I have informed you of my leaky ceiling 2x now, and since this is the 3rd, I figure you must be overwhelmed taking care of other issues. I am going to propose a solution for you. If you are unable to take care of this issue by the 1st of the month, I am going to call a roofer, and have someone come inspect it with an estimate. I will be deducting this from my rent. Since I am immune compromised, I am not able to withstand a month long wait to have mold/mildew/water issues addressed. Thanks for your understanding"

I bet that will make him put a wiggle in it. He will not want you deducting fees off the rent, nor will he want a qualified roofing company inspecting his property. They are required to make reports about finding mold situations, and water situations and the health board would force him to fix it. Once mold sets into the wood, its darn hard to get rid of. I would make a pest of myself to get that fixed.

Hang in there. its not fun to take an umbrella to bed.

You said something about this small leak being on or near your heating/cooling vent. Your's is probably a real leak, but mine was just condensation from the humidity and the A/C. When the humidity came down, the leak stopped. It happens, because I keep my back door open a crack for the dog. Sometimes it even drips down the doors.

I hope your super can fix it, before it does any damage to your furnishings.

Oh take pictures!

just in case any evidence is needed.

Great idea!! Thanks for the suggestion......I'm calling my DS now and asking him to bring home the digital camera.

In NJ, (different states may have different laws) I had to get flood insurance by law because I was in a "flood Zone" River Levees eventually eliminated that. The other side of town next to another River, flooded bad one time.

Sheesh Kelly, when it rain's it pours (cheesy pun intended )! Everyone has given you good advice already. I don't understand people sometimes, if he keeps waiting it's just gonna cost him more money to fix. I'd be worried about the mold too. If you can smell the damp wood there's probably A LOT of moisture up there.

Kelly, if you have water dripping through the ceiling...then you have had a leak for some time. It takes a good bit of water to breakdown that drywall to that point. I would ask the homeowner to get someone to inspect that area for mold and wood rot. Heck I'd even insist he get a termite inspection too. We had a similar leak in a closet ...in a rental house. The wet area attracted termites and they ate wood, drywall paper and books that were stored in that closet.
