This report presents details of experiments and preliminary guidelines for maintaining sprayed polyurethane foam PUF roofing systems, which have been used in increasing numbers in recent years by government and the private sector. Many of these PUF roofs are now requiring maintenance because of improper materials, improper application, or length of time in service age. Standard methods and procedures for maintaining and repairing PUF roofs have not yet been developed or used by manufacturers or contractors to any great extent. In general, each contractor has his own special maintenance procedures. A number of experiments have been conducted by NCEL in an investigation to establish effective procedures for maintenance of PUF roofing systems. Author
