Premium Wind & Water Seal from MFM Building Products Corp. provides underlayment protection for all types of roofing jobs. It is comprised of a self-adhering, rubberized asphalt layer coated with a tough polymer film that self-seals around nails and fasteners. The product prevents leaks caused by ice dams and low slope applications and it protects structures even if the finished roof surface has blown off. Its peel-and-stick application allows for easy installation on eaves, valleys, vents and skylights for retrofit and new construction projects. For more information, call 800-882-7663 or visit
