We bought a property in 11 / 12 in contra coats county , and found out the roof leaked after a big rainstorm on 12 / 5 / 12 . My Realtor contacted the listing agent ( who was also the property manager ) . The listing agent denied having any prior knowledge of any problem with the roof . We were able to get hold of the prior tenants and they provided us with the screen shot of " face book " conversation showing the tenants informing the landlord of leaky roof and also stated that the problem had gone on for two years . The seller and the listing agent have refused to take any responsibility . Our general inspection didn't show any problem with the roof . When we repaired the roof , the roofer said the lining under the tiles were torn . What is our option ? going after the general inspector ? seller and agent ?what is the statue of limitation in Contra Costa County in Northern CA? thanks all.
