A flat roof cover system comprising a facia edge plate and a generally flat roof substructure which includes a nailable perimetral edge strip, and a waterproof rubber-like membrane cover of a length to extend beyond the edge strip. A rigid clip having a flat nailing portion is nailed to the upper face of the edge strip. The clip has a rigid inversely disposed V-shaped portion with a wall extending down along the building which terminates in a lock flange. A facia plate, having a like deformable resilient V-shaped portion terminating in a reversely turned edge bearing on said membrane edge and the clip plate gravel stop surface beneath it, has a latch socket to snap over said lock flange.
An improved roof edge ventilation strip serving as a starter strip to underlay the first course of shingling along a roof line. The roof edge ventilation strip comprises a roofing panel which is, in use, at substantially the same angle to the vertical as the roof to which it is attached. The material of the ventilation strip is wavy or corrugated for providing added strength. A horizontal soffit section of the ventilation strip has louvers which add strength to the ventilation strip and permit a ladder to be leaned against the strip outer edge. A vertical fascia section provides for fastening the ventilation strip in abutment to a vertical side of a house or a building. An alternate embodiment comprises a protruding drip edge to insure water run-off away from the house.
A metal shingle system which is resistant to leakage, even under severe weather conditions. The key attribute of the new system to the design of the side edge of the shingle such that water that seeps between adjacent shingles cannot be blown upward. Briefly, the top edge is overturned and the bottom edge is underturned such that they can be interconnected as is well known in the art. One side edge is folded to form a gutter area into which water that seeps between laterally adjacent shingles is collected and drained onto the lower row of shingles. The top of the gutter area is blocked by the overturned top edge, which extends into the gutter region. Also disclosed is an improved tool for cutting the shingles, such as is needed around obstructions and at the end of the roofline.
A facia border for covering the periphery of a structure between the roof and a soffit includes mounting clips attached at periodic peripheral locations for slidably attaching facia trim at detented positions.
In a node (110) communicating with other nodes in a network (150), a system and method for performing cryptographic-related functions is provided. The node (110) receives and transmits inputs and outputs requiring cryptographic-related processing. When cryptographic processing is required, the node (110) transmits a predefined message to a cryptographic processing component in the node (110) that then performs the desired cryptographic-related processing.
