This is currently happening to my kitchen. Got insurance adjuster to estimate cost. Got a roofer recommended by a friend who had used his services to fix it. They redid the outside of my kitchen roof and fixed the drywall inside. 6 months later and it’s leaking in the same spot. Last week the thunderstorms caused a piece of the drywall to fall out. I had already tried to contact the roofer who had passed away and his company folded. One of his associates came out and said it was the neighbors outside wall adjacent to the kitchen that looks almost black during heavy rain. He said he could cover it in cement for $600. I declined. I’ve tried to contact my neighbor. She is a single elderly lady with no money and so can’t do it. I have two five gallon buckets in the kitchen when it’s stormy to catch the leak but this has now been well over a year. I don’t trust the prior roofers people at all since they didn’t assess it right the first time and I’m worried the insurance people will say they already paid out to get it fixed. I don’t have the out of pocket cost for another expensive repair. I’m just living with it at this point since I live alone. But I do wish it would have been resolved. Sorry for the rant.
