1. A venting device for a structure, said structure enclosing an interior space, said venting device comprising:
- an elongate top panel portion having an interior surface;
a pair of opposing ventilating portions spaced apart on the interior surface of said elongate top panel portion and defining a portion of the interior surface of said top panel portion between said pair of opposing ventilating portions, each of said ventilating portions having an interior side, an exterior side and an underside, each of said ventilating portions having a multiplicity of separate air passages extending from the interior side to the exterior side; and
an elongate sheet of air permeable material having an upper surface, the upper surface of said sheet of air permeable material being sealingly affixed to the underside of each of said pair of opposing ventilating portions and being otherwise free from attachment to said pair of opposing ventilating portions and said elongate top panel portion, wherein a portion of said sheet of air permeable material is freely suspended between said opposing ventilating portions, and wherein the area of the upper surface of the portion of said sheet of air permeable material freely suspended between said opposing ventilating portions is at least equal to the area of the portion of the interior surface of said elongate top panel portion defined between said opposing ventilating portions.

Abstract
A precipitation resistant ventilator for a structure enclosing an interior space. The ventilator encloses a space that is in communication with the structure interior space. A thin sheet of air permeable water resistant material is disposed within the ventilator interior. The thin sheet of air permeable water resistant material forms a barrier that excludes the entry of precipitation and other foreign matter into the roof structure while still allowing air exchange.

8. A venting device for a structure, said structure enclosing an interior space, said venting device comprising:
-
an elongate top panel portion having an interior surface, said elongate top panel portion being configurable in a generally anticlinal shape having a crest, the crest being oriented along the longitudinal axis of said elongate top panel portion;
a pair of opposing ventilating portions spaced apart on the interior surface of said elongate top panel portion and defining a portion of said interior surface of said top panel portion between said pair of opposing ventilating portions, each of said ventilating portions having an interior side, an exterior side and an underside, each of said ventilating portions having a multiplicity of separate air passages extending from the interior side to the exterior side; and
an elongate sheet of air permeable material having an upper surface, the upper surface of said sheet of air permeable material being sealingly affixed to the underside of each of said pair of opposing ventilating portions and affixed to said elongate top panel portion proximate the longitudinal axis of said elongate top panel portion, said sheet of air permeable material being otherwise free from attachment to said pair of opposing ventilating portions and said elongate top panel portion, wherein a first portion of said sheet of air permeable material is freely suspended between one of said pair of opposing ventilating portions and said elongate top panel portion, wherein a second portion of said sheet of air permeable material is freely suspended between the other of said pair of opposing ventilating portions and said elongate top panel portion, and wherein the sum of the areas of said first and second portions of said sheet of air permeable material is at least equal to the area of the portion of the interior surface of said elongate top panel portion defined between said opposing ventilating portions. - View Dependent Claims (9, 10, 11, 12, 13)

14. A venting device for a structure, said structure enclosing an interior space, said venting device comprising:
-
an elongate top panel portion having an interior surface;
at least one ventilating portion on the interior surface of said elongate top panel portion, said ventilating portion having an interior side, an exterior side and an underside, the interior side of said ventilating portion being spaced apart from a first longitudinal margin of said elongate top panel portion and defining a portion of said interior surface of said top panel portion between said ventilating portion and said first longitudinal margin of said elongate top panel portion, said ventilating portion having a multiplicity of separate air passages extending from the interior side to the exterior side; and
an elongate sheet of air permeable material having an upper surface, the upper surface of said sheet of air permeable material being sealingly affixed to the underside of said ventilating portion and affixed to said elongate top panel portion proximate the first longitudinal margin of said elongate top panel portion, said sheet of air permeable material being otherwise free from attachment to said ventilating portion and said elongate top panel portion, wherein a portion of said sheet of air permeable material is freely suspended between said ventilating portion and said elongate top panel portion, and wherein the area of said portion of said sheet of air permeable material freely suspended between said ventilating portion and said elongate top panel portion is at least equal to the area of the portion of the interior surface of said top panel portion defined between said ventilating portion and said first longitudinal margin of said elongate top panel portion. - View Dependent Claims (15, 16, 17, 18)
