I am a home owner in Indiana. I have signed a contingency contract with roofing company. Roofing company never return signed contract back to me and they helped to process the claim with an insurance company. Insurance company not approved 100% estimate provided by roofing company. They have rejected contractors overhead and profit charges due to not complex project. Roofing company asked me to hire a public adjuster and i refused as it was not mentioned in the contingency contract. I told them to cancel the contract based on insurance not approving their O&P charges. Now roofing company is threatening to file a lien on my property as i am not moving forward them. They are asking $2000 for cancellation fee and few emails they sent to insurance company. They have not performed any work , not provided labor or material . Only they sent few emails to insurance company to get my overall claim approved. Please let me know if roofing can company sue me and what are my options. Thanks and appreciate your help.
