Abstract: An apparatus for retrofit connection of a roof frame to a support member therebelow includes a claw member having a load bearing flange to be driven into an interface between a roof sheathing and a top edge of the roof frame, and a tie-down member to be mounted to a vertical surface of the support member. The tie-down member is connected to the claw member to allow various angular positions of the load bearing flange depending on roof slopes.

Abstract: A method for securing a roof sheathing and shingles in a retrofitting reinforcement of an existing roof structure, the shingles being laid on the roof sheathing in a partially overlapping pattern, comprises (a) driving a plurality of fasteners down through selected shingles and the roof sheathing in a selected area of the roof structure into at least one of underlying roof frames; and (b) applying a water-resistant coating to the roof structure to seamlessly cover exposed surfaces with exposed ends and sides of all shingles in the selected area.

Abstract: An apparatus and method is provided for tying down an existing roof frame to resist windstorm uplift forces, in which an elongate connector is inserted slantingly upward through a hole through the roof frame, allowing an upper end of the connector to protrude from the roof frame to receive a head member which is detachably attached thereto in order to prevent the roof frame from moving upward relative to the connector under an uplift force. The lower end of the connector is secured to an underlying wall such that the connector applies a restraining force against wind uplift forces.
