You may have a first party claim against State Farm. You need a lawyer to review the lease, the renter's policy, the work orders, and the correspondence between all involved. A first party insurance claim is technical and Small Claims Court typically does not allow discovery. The dollar amount of damage to your property will likely guide attorneys in deciding whether to take on your case on a contingency fee.
You may be entitled to vacate if you comply with the lease and the law. Read your lease. Then read the Texas statute carefully: http://www.statutes.legis.state.tx.us/Docs/PR/h. You may sue your landlord in small claim court, but your damages will be capped at $10,000.

My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
