Can I Put a Mechanics Lien on a Roofing Company? Yes, you can put a mechanic's lien on a roofing company if they fail to complete the work as agreed or if they haven't been paid for services rendered. A mechanic’s lien is a legal claim against the property for unpaid work or materials. To file a lien, you must follow specific legal procedures, which may vary by state. Typically, the roofing company or contractor must be given a notice of non-payment before filing. The lien can be enforced by a court, potentially leading to a forced sale of the property. It's advisable to consult with a legal professional to ensure proper filing and compliance.
