Abstract: A roof ridge vent mat for installation overlying an open roof ridge to provide ventilation to a space beneath a roof is provided. The ridge vent mat is a continuous elongate material of randomly convoluted polymeric filaments having an openwork upper face, an openwork lower face, a plurality of hollow recesses extending into the mat and opening into the lower face, and opposite longitudinally extending openwork side edges. The openwork upper face is formed of randomly convoluted filaments formed to provide a relatively flat surface of sufficient density to catch heads of fasteners. The plurality of hollow recesses is defined by a plurality of upstanding openwork walls of convoluted filaments that extend from the upper face to the lower face of the mat. The upstanding openwork walls are arranged in a latticework structure such that no unobstructed passageway extent through the mat through which wind-blown rain and snow can freely pass into the side edges of the mat and laterally pass through the mat.

Abstract: A roof ridge vent for installation overlying an open roof ridge to provide ventilation to a space beneath a roof is provided. The ridge vent is a continuous, elongate mat of randomly convoluted polymeric filaments having an openwork upper face, an openwork opposite lower face, a plurality of hollow recesses extending into the mat and opening into the lower face, and opposite longitudinally-extending openwork side edges. The openwork upper face is formed of randomly convoluted filaments formed to provide a relatively flat surface of sufficient density to catch heads of fasteners. The plurality of hollow recesses is defined by a plurality of upstanding openwork walls of convoluted filaments that extend from the upper face to the lower face of the mat. The upstanding openwork walls are arranged in a latticework structure such that no unobstructed passageways extend through the mat through which wind-blown rain and snow can freely pass into the side edges of the mat and laterally pass through the mat.

Abstract: A roof ridge vent comprises a one-piece, elongate body rollable into a spiral roll. The vent body has an elongate upper wall with a pair of longitudinally-extending side edges, an underside, and a plurality of bracing walls depending therefrom. The vent body further includes a pair of grillwork walls with ventilation openings extending downwardly and outwardly from the side edges of the upper wall. Still further, the vent body includes a pair of longitudinally-extending sidewalls that project from the outer edges of each of the grillwork walls and that are disposed upright with respect to the upper wall. Each of the sidewalls has a continuous, longitudinally-extending top strip and a spaced apart pair of longitudinally-extending walls depending from the top strip. The pair of walls includes a series of drainage openings which provide drainage paths through the sidewalls and which permit the sidewalls to be rolled into the spiral roll.

Abstract: A flashing material for a building structure is provided. The flashing material includes a flexible water-resistive membrane having an upper textured surface with a series of separate, laterally paced-apart, elongate spacers bonded thereto. The elongate spacers can be polymeric filaments that define an air space and drainage paths across the upper surface of the membrane. Preferably, the filaments have a series of depressions formed therein that provide transverse drainage paths across the filaments. Sill, decking and other building structure assemblies and methods of making the flashing material are provided.
