In January 1994 HUD amended the Manufactured Home Construction and Safety Standards to improve the resistance of manufactured homes to wind forces in areas prone to hurricanes. In part, the amendments provided that manufactured homes designed to be sited in high wind areas must be designed to resist either the design wind loads in a specified industry performance standard or alternative wind pressures set out in a prescriptive Table included in the regulations. Some questions have arisen concerning: Whether manufacturers that design their products using the wind pressures in the Table must provide roof sheathing under metal roofing; and the appropriateness of the testing of metal roofing that has been done. Therefore, the Department finds it necessary to reiterate, through this Interpretative Bulletin (IB), its current policy with regard to the regulations. A related advance notice of proposed rulemaking is published elsewhere in today's Federal Register.
