Abstract

A roof ventilation apparatus or cover comprising a vent base having an opening formed therethrough, a vent cap attached to the vent base and at least partially covering the opening of the vent base, and a flexible base attached to the vent base and/or the vent cap. The flexible base may be in covering relationship to an outer periphery of the vent base or the vent cap. Furthermore, the flexible base may be configured to be molded to corrugations of a metal roof and secured thereto. The roof ventilation apparatus may be used in a method of replacing composite or wood shake roof shingles on a roof with metal roof panels and at least one vent opening in a sloped portion of the roof spaced away from a ridge line of the roof.

Claims

exact text as granted — not AI-modified
1 . A method of attaching a roof ventilation apparatus to a roof, the method comprising:
 attaching to the roof a ventilation apparatus comprising a vent base, a vent cap, and a flexible base, the roof ventilation apparatus having a passage therethrough to communicate with an opening formed through the roof;   molding the flexible base to a surface portion of the roof surrounding the opening formed through the roof; and   securing the flexible base to the roof.   
     
     
         2 . The method of  claim 1 , further comprising attaching the vent cap to the vent base such that the vent cap substantially covers an opening of the vent base aligned with the opening formed through the roof. 
     
     
         3 . The method of  claim 1 , wherein the vent cap is integrally formed with the vent base and substantially covers an opening of the vent base aligned with the opening formed through the roof. 
     
     
         4 . The method of  claim 1 , wherein the flexible base is secured to the roof with at least one of an adhesive and one or more mechanical fasteners. 
     
     
         5 . The method of  claim 1 , wherein the surface portion of the roof to which the flexible base is molded is corrugated. 
     
     
         6 . The method of  claim 1 , wherein the roof comprises sheathing and metal roof panels attached onto the sheathing. 
     
     
         7 . The method of  claim 1 , wherein the flexible base is made of at least one of rubber, a moldable hydrophobic material, and a flexible metal lining. 
     
     
         8 . The method of  claim 6 , wherein the sheathing is at least one of plywood and oriented strand board (OBS) 
     
     
         9 . The method of  claim 1 , wherein the flexible base is permanently seamed to a flange portion of the vent cap. 
     
     
         10 . A roof vent cover comprising:
 a vent base having an opening formed therethrough;   a vent cap attached to the vent base and at least partially covering the opening of the vent base; and   a flexible base attached to the vent base and/or the vent cap in covering relationship to an outer periphery of the vent base or the vent cap and configured to be molded to corrugations of a metal roof and secured thereto.   
     
     
         11 . The roof vent cover of  claim 10 , wherein the flexible base is made of at least one of rubber, a moldable hydrophobic material, and a flexible metal lining. 
     
     
         12 . The roof vent cover of  claim 10 , wherein the flexible base comprises one or more contours configured to align with one or more contours of the corrugated metal roof. 
     
     
         13 . The roof vent cover of  claim 10 , wherein the vent base has a tube portion protruding upward toward the vent cap and a flange portion configured to rest against the roof or against sheathing under the roof. 
     
     
         14 . The roof vent cover of  claim 13 , wherein the flexible base is permanently seamed to the flange portion of the vent cap. 
     
     
         15 . The roof vent cover of  claim 10 , wherein the vent base and vent cap are part of a standard static vent having pre-cut slots around the edge to allow an edge portion to be bent for providing securement to the roof. 
     
     
         16 . The roof vent cover of  claim 10 , wherein the vent base comprises a flat portion attachable to sheathing of the roof and a tube formed around the opening of the vent base and configured to protrude upward from the flat portion through metal roofing attached to the sheathing. 
     
     
         17 . The roof vent of  claim 16 , further comprising a rubber vent boot having a graduated conical configuration extending upward from the flexible base around an opening of the flexible base, wherein the rubber vent boot is installed over the tube of the vent base. 
     
     
         18 . The roof vent of  claim 17 , wherein the vent cap is a hood and is attached to at least one of the vent base tube and the rubber vent boot. 
     
     
         19 . The roof vent of  claim 10 , wherein the flexible base is configured to be secured to the roof using a mechanical fastener and/or an adhesive. 
     
     
         20 . The roof vent of  claim 10 , wherein at least one of the vent base and vent cap are made of at least one of metal, plastic, and structural composite. 
     
     
         21 . A method of replacing composite or wood shake roof shingles on a roof with metal roof panels, wherein the roof has a vent opening in a sloped portion of the roof spaced away from a ridge line of the roof, the method comprising:
 removing composite or wood shake roof shingles from sheathing of the roof;   installing a plurality of metal roof panels and a roof vent cover onto the roof, the metal roof panels being installed onto the sheathing such that the vent opening is not covered by the metal roof panels, the roof vent cover comprising a flexible base and a passage that communicates with the vent opening in the roof;   molding the flexible base to conform with corrugations of the metal roof panels; and   securing the molded flexible base to at least a portion of the metal roof panels.   
     
     
         22 . The method of  claim 21 , wherein the flexible base has an opening formed therethrough substantially aligned with the vent opening in the roof. 
     
     
         23 . The method of  claim 21 , wherein the roof vent cover further comprises at least one of a vent base and a vent cap, wherein the flexible base is attached to an outward-facing surface of at least one of the vent base and the vent cap, wherein an opening of the vent base is aligned with the vent opening in the roof. 
     
     
         24 . The method of  claim 23 , wherein the flexible base is permanently seamed to a flange portion of the vent cap. 
     
     
         25 . The method of  claim 21 , wherein the flexible base is secured to the roof with at least one of an adhesive and one or more mechanical fasteners. 
     
     
         26 . The method of  claim 21 , wherein the flexible base is made of at least one of rubber, a moldable hydrophobic material, and a flexible metal lining. 
     
     
         27 . The method of  claim 21 , wherein the sheathing is at least one of plywood and oriented strand board (OBS).
