Adjustable filtered roof ridge ventilator

A roof ridge ventilator assembly to be installed overlying the open ridge and along the length of the roof of a building which is adjustable to accommodate a variety of different roof pitches and directs and filters the flow of air from the interior of the building to the exterior of the building, comprising:

• an elongate filter medium having a predetermined length, width and thickness, said width selected to at least be slightly wider than the width of the open ridge;
• an elongate ventilator member overlying and connected to said filter medium, said ventilator member having a predetermined length and width and top and bottom sides, being flexible in a lateral direction and formed by a top wall member, said top wall member having a width slightly less than said predetermined width of said ventilator member and being slightly bowed along its longitudinal center line to form a central bowed portion with first and second planar portions integrally connected on either longitudinal side of said bowed portion and with the concave side of said bowed portion being said bottom side and facing said filter medium, said first and second planar portions substantially being contained in first and second planes, respectively, that intersect above said ventilator member, said ventilator member including a pair of outer side walls, one each integrally formed with a respective first and second planar portion, said side walls extending along the longitudinal length of and depending from their respective first and second planar portions extending toward said filter medium, said side walls including a plurality of substantially parallel slots extending therethrough and along the entire longitudinal length of said side walls, distal outer ends of said side walls opposite respective first and second planar portions including an upturned edge which extends toward said first and second planar portions to a position proximate the respective planes containing said first and second planar portions;
• and
• a plurality of brace members positioned at predetermined intervals along the length of said bottom side of said first and second planar portions for supporting said ventilator member against said roof surface and trapping said filter medium therebetween.
