I bought a prefab house a couple fo years ago. The company was sold shortly after. The new owner signed an agreement with former owner relieving new owner of all liability for houses sold prior to the change of ownership. The new owner has since evaluated the roofing system and made significant changes based on design flaws he found. He has also instructed prior owners on making retrofits (at their expense).
What is my recourse if any in getting the former owner to assume liability for roofing retrofits?
