         8 . The roofing membrane of  claim 1 , wherein:
 the waterproof membrane comprises a third color that is different than the first color and the second color.   
     
     
         9 . A roofing membrane, comprising:
 a waterproof membrane having a top major surface that has a first color;   a first liner having a top surface and a bottom surface, wherein:
 the bottom surface is removably coupled with the top major surface of the waterproof membrane; and 
 the first liner has a second color that is different than the first color; 
   a second liner having a top surface and a bottom surface, wherein:
 a bottom surface of the second liner is coupled with the top surface of the first liner; 
 the second liner has a third color that is different than the first color and the second color; and 
 a force coupling the first liner and the second liner is greater than a force coupling the first liner and the waterproof membrane. 
   
     
     
         10 . The roofing membrane of  claim 9 , wherein:
 the first liner and the second liner comprise at least one material selected from the group consisting of: a paper material, a polymeric material, and a polymer-coated paper material.   
     
     
         11 . The roofing membrane of  claim 9 , wherein:
 each of the first liner and the second liner has a thickness of between about 0.1 mils and 15 mils.   
     
     
         12 . The roofing membrane of  claim 9 , wherein:
 the bottom surface of the first liner is removably coupled with the top major surface of the waterproof membrane using a first adhesive; and   the bottom surface of the second liner is bonded with the top surface of the first liner using a second adhesive that is different than the first adhesive.   
     
     
         13 . The roofing membrane of  claim 12 , wherein:
 the first adhesive comprises a pressure sensitive adhesive.   
     
     
         14 . The roofing membrane of  claim 12 , wherein:
 the second adhesive comprises a permanent bonding agent.   
     
     
         15 . The roofing membrane of  claim 12 , wherein:
 the second color and the third color comprise complementary colors.   
     
     
         16 . A method of installing a roofing membrane, comprising:
 positioning a roofing membrane atop an exposed roofing surface, the roofing membrane comprising:
 a waterproof membrane having a top major surface having a first color; 
 a first liner having a top surface and a bottom surface, wherein:
 the bottom surface of the first liner is removably coupled with the top major surface of the waterproof membrane; and
