Can I Put a Mechanics Lien on a Roofing Company? Depending on your state's rules and the particulars of your case, you may be able to file a mechanic's lien against a roofing firm. A mechanic's lien is a lawsuit brought by suppliers, subcontractors, or contractors who have not received payment for their labor or supplies. Those parties may be able to put a lien on your property if a roofing business completed work on it without paying suppliers or subcontractors. You must first verify your eligibility under state law, though, if you are the one attempting to place a lien against the roofing company.
