         5 . The vent and flashing system of  claim 1 , wherein the internal check valve includes a first port end and a second port end. 
     
     
         6 . The vent and flashing system of  claim 5 , wherein the first port end is configured to exhaust fluid and gas. 
     
     
         7 . The vent and flashing system of  claim 5 , wherein the second port end is configured to inhibit penetration by fluid and gas. 
     
     
         8 . The vent and flashing system of  claim 1 , wherein the flexible bottom is configured to be mounted flush to a surface of the metal roof and create a watertight seal. 
     
     
         9 . The vent and flashing system of  claim 1 , wherein the base plate is substantially constructed from a sheet metal. 
     
     
         10 . The vent and flashing system of  claim 8 , wherein the flexible bottom of the base plate is constructed from a rubber material. 
     
     
         11 . The vent and flashing system of  claim 1 , wherein the base plate is a triangular shape. 
     
     
         12 . The vent and flashing system of  claim 1 , wherein the base plate is an “A”-shape. 
     
     
         13 . The vent and flashing system of  claim 1 , wherein the base plate includes a cavity;
 wherein the cavity at least partially houses the internal check valve therein; and   wherein the cavity includes a cavity-shape equal to the shape of the vent.   
     
     
         14 . The vent and flashing system of  claim 1 , wherein the cover includes at least one fastener for removably fastening the cover to the base plate. 
     
     
         15 . The vent and flashing system of  claim 1 , wherein the cover is a triangular shape. 
     
     
         16 . The vent and flashing system of  claim 1 , wherein the cover is an “A”-shape. 
     
     
         17 . The vent and flashing system of  claim 1 , wherein said vent and flashing system is configured for installation over a middle of at least one of the plurality of ribs. 
     
     
         18 . The vent and flashing system of  claim 1 , wherein the vent and flashing system serves to make a covered portion of a building effectively weather resistant. 
     
     
         19 . A vent and flashing system for installation on a metal roof, the metal roof including a plurality of panels, the plurality of panels each having a plurality of ribs thereon, the vent and flashing system comprising:
 a vent and flashing assembly including:
 a base plate including a flexible bottom; 
 a vent including a shape having a bottom-end wider than a top-end; 
 an internal check valve installed in the vent; 
 a cover for removable placement over the vent; and 
 a cap for covering the internal check valve; 
 wherein the vent and flashing system is configured for installation 
 wherein the internal check valve includes a first port end and a second port end; 
 wherein the first port end is configured to exhaust fluid and gas; 
 wherein the second port end is configured to inhibit penetration by fluid and gas; 
 wherein the base plate is substantially constructed from a sheet metal; 
 wherein the flexible bottom of the base plate is constructed from a rubber material; 
 wherein cover includes at least one fastener for removably fastening the cover to the vent; 
 over a middle of at least one of the plurality of ribs; 
 wherein the flexible bottom is configured to be mounted flush to a surface of the metal roof and create a watertight seal; and 
 wherein the vent and flashing system when installed allows that installed-portion to be effectively weather resistant to moisture entering. 
   
     
     
         20 . A method for customized vent and flashing installation on a metal roof, the metal roof including a plurality of panels, the plurality of panels each having a plurality of ribs thereon, the method comprising the steps of:
 providing a vent and flashing system, the vent and flashing system including:
 a base plate including a flexible bottom; 
 a vent including a shape having a bottom-end wider than a top-end;
