I had a roof put on in 2011. Still under warranty. They removed some plywood sheeting that had my bathroom vents on it. They never installed new vents thus the hot steam from both bathrooms have been venting into the attic ever since. I now have mold everywhere throughout the attic. It is code to vent the bathroom air outside the attic even back in 2011. Village doesn't have any record of an inspection. Is the contractor liable for mold remediation?
