South Bay on Gull Rock

I have a noise emanating from the roof. I notified the property manager; he came to hear the noise and said he couldn't hear it. I have a room and bathroom as well as a stairwell which vibrate all day, making it impossible to work, think, or sleep. After telling me he couldn't hear it, he slandered me, throwing accusations which were unrepeatable and defamatory. The issue needs to be fixed.
