Well, after a significant amount of investigation, I've decided the source of leaks is not the air conditioner. The 32 year old tile roof is the problem. It has to be replaced. My next dilema is the fact that the home is a duplex. The adjoining home owner says his roof is not leaking and does not need to be replaced. I have credible information from the former owner's housekeeper that his roof has leaked in the past, but the HOA says they can't make him replace his roof. I will have to pay extra to have my side of the roof replaced because the tiles presently on the roof are no longer made and my new roof must match his existing roof. Further, the tiles I'll have to buy must be painted to match his roof, since the new product does not come in a similar color. I think I'll have to replace the plywood decking and attic insulation. I feel the need to remove everything that may have been wet or dampened by water coming in through the tiles. Naturally, the gutters, facia, soffets will also be replaced as well. Is all of this work overkill? I'm afraid of mold and mildew. I'd also like to take out the ceilings in every room of the home. (They're nasty popcorn ceilings anyway) and do some additional home improvements. Do you think I can/shold hire a GC to get all of this accomplished (time and money are primary concerns) or just sub-out each task separately? Arrrg! I'm sick over this . . . HOA/next door neighbor situation . . . Any thoughts?
