Can I Put a Mechanics Lien on a Roofing Company? Yes, you can put a mechanic's lien on a roofing company if you haven't received the agreed-upon work or payment. In many states, subcontractors, suppliers, and homeowners can file a lien to secure payment for services rendered or materials provided. Before filing, ensure you have a valid contract or proof of unpaid work. The process involves notifying the roofing company in writing and following local legal requirements, including deadlines. Filing a lien may lead to a lawsuit if the issue isn’t resolved. It’s important to consult with a legal professional to understand your rights and the proper procedures. Be aware of the legal consequences for both parties.
