         2 . The roofing system of  claim 1 , wherein the upper portion of said ice backing flashing layer has at least one fold defining an edge extending at least partially toward the bend between the upper and lower portions. 
     
     
         3 . The roofing system of  claim 2 , wherein the at least one fold is positioned between a top distal end of the upper portion and the bend between the upper and lower portions. 
     
     
         4 . The roofing system of  claim 2 , wherein the at least one fold includes two or more folds positioned between a top distal end of the upper portion and the bend between the upper and lower portions. 
     
     
         5 . The roofing system of  claim 1 , further comprising a second underlayment layer adjacent to and above the upper portion of said ice backing flashing layer. 
     
     
         6 . A roofing system, comprising:
 a first underlayment layer; and   an ice backing flashing layer adjacent to and above said first underlayment layer;   said ice backing flashing layer including an upper portion attachable to an upper surface of a roof, a lower portion attachable to a fascia portion of the roof, and a bend between the upper and lower portions attachable over an edge of the roof;   a second underlayment layer adjacent to and above the upper portion of said ice backing flashing layer; and   a drip edge layer adjacent to and above the second underlayment layer.   
     
     
         7 . The roofing system of  claim 6 , further comprising a third underlayment layer adjacent to and above the drip edge. 
     
     
         8 . The roofing system of  claim 1 , wherein the bend has an interior angle over the edge of the roof of at least ninety degrees. 
     
     
         9 . The roofing system of  claim 1 , wherein said ice backing flashing layer consists of metal. 
     
     
         10 . The roofing system of  claim 1 , wherein said first layer is adhesively attached to the bottom portion of said ice backing flashing layer. 
     
     
         11 . The roofing system of  claim 1 , further comprising a gutter secured to the lower portion of said ice backing flashing layer, wherein the lower portion of the ice backing flashing layer extends below the gutter. 
     
     
         12 . The roofing system of  claim 11 , wherein the lower portion of said ice backing flashing layer includes a lip extending outward from the fascia portion of the roof below the gutter. 
     
     
         13 . The roofing system of  claim 1 , wherein the upper portion of said ice backing flashing layer includes a curved distal end with a distal edge extending away from the upper surface of the roof. 
     
     
         14 . The roofing system of  claim 13 , wherein the curved distal end is secured to the roof with a plurality of clips. 
     
     
         15 . The roofing system of  claim 1 , wherein the bend between the upper and lower portions includes a first bend and a second bend forming a nose portion extending at least partially away from the roof. 
     
     
         16 . A method of preventing ice backing, comprising the steps of:
 securing a first underlayment layer to an upper surface of a roof;   securing an ice backing flashing layer to the roof adjacent to and above said first underlayment layer, the ice backing flashing layer including an upper portion, a lower portion, and a bend between the upper and lower portions, wherein the upper portion is secured to the upper surface of the roof and the lower portion is secured to a fascia portion of the roof;   securing a second underlayment layer adjacent to and above the upper portion of the ice backing flashing layer; and   securing a drip edge layer adjacent to and above the second underlayment layer.   
     
     
         17 . (canceled) 
     
     
         18 . (canceled) 
     
     
         19 . The method of  claim 16 , further comprising the step of:
 securing a third underlayment layer adjacent to and above the drip edge.   
     
     
         20 . The method of  claim 16 , further comprising the step of:
 securing a gutter to the lower portion of the ice backing flashing layer,   wherein the lower portion of the ice backing flashing layer extends below the gutter.   
     
     
         21 . The method of  claim 20 , wherein the lower portion of the ice backing flashing layer includes a lip extending outward from the fascia portion of the roof below the gutter. 
     
     
         22 . The method of  claim 16 , wherein the upper portion of the ice backing flashing layer includes a curved distal end extending away from the upper surface of the roof. 
     
     
         23 . The method of  claim 22 , wherein the curved distal end is secured to the roof with a plurality of clips. 
     
     
         24 . The method of  claim 16 , wherein the upper portion of the ice backing flashing layer includes a first fold between a top distal end of the upper portion and the bend between the upper and lower portions. 
     
     
         25 . The method of  claim 24 , wherein the upper portion of the ice backing flashing layer includes a second fold between the top distal end of the upper portion and the bend between the upper and lower portions.
