This contractor had an issue with my general contractor about a roofing job that he wasn\\\\t awarded work on. He came onto my property and insisted that the sub contractor working on my roof should stop work, that they were working illegally. He then came to my door and said he had called code enforcement, that he did quality work which my workers were not licensed for. My contracted work was interrupted and I was verbally harassed and later had to respond to code enforcement. He had no right to interfere with the work being done on my property.
