Pollard's Home Improvements and Custom Renovations

My roof was left uncovered for nearly 6 months because he quit the job. I had to have my son-in-laws cover the rest of the roof after purchasing the shingles themselves. Before they were able to get the roof covered, we had a large rain storm, and now there is water damage, and possible mold, in my home. My insurance company will not cover the expense of repairs because it was caused due to unfinished work by Pollard. I have taken him to court to get my money back, but the judge stated that he completed the work he was paid to do. However, the contract stated he would not receive the remaining balance until completion of the job, which he did not do.
