Always get a LIEN WAIVER. I was "fast talked" by a roofer who offered a great price. I was pretty desperate as Allstate had dropped me after 40 years with NO CLAIMS. Roof leaked so after checking with others I let a contractor do the work. He never showed up during the application and didn't answer call or messages. Finally learned that he'd hit the road for greener, deperate people without paying the roofing supplier. The supplier wants almost $4,000 in addition to what I had already paid to the "thief". In Georgia, it's legal for a supplier to place a lien on property which received the service. ALWAYS GET A LIEN WAIVER. This was an itinerate contractor who cruised the areas looking for homes with missing shingles and a sucker.
Do as I say, not as I did!!
