  • Perimeter securement for membrane roof and method of attaching
    Patent number: 4932171
    Abstract: A method of attaching the perimeter of a membrane roof to a roof deck and an abutting parapet wall is disclosed. The method employs a flexible attachment strip which is mechanically fastened to either the parapet wall or the roof deck. The membrane covers the attachment strip and is secured to the horizontal portion of the attachment strip and adhered to the parapet wall. The attachment strip is a flexible strip of either fabric reinforced or non-reinforced membrane. The attachment member can be either attached to the parapet wall or can be attached to the roof deck at the foot of the parapet wall. This improves the wind uplift resistance of the perimeter securement and reduces installation cost.
