         38 . The article of  claim 31 , further comprising a release layer proximate the fourth cloth layer, the release layer to expose an adhesive to permit coupling of the water resistant underlayment portion to an underlying structure. 
     
     
         39 . An article comprising:
 a water resistant underlayment portion, wherein the water resistant underlayment portion consists essentially of:   first and second layers of a cloth material;   a first joining layer, disposed between the first and second layers of the cloth material, to join the first and second layers of the cloth material;   one or more layers of a coated cloth material, coated on first and second sides, with at least one of glue or plastic;   third and fourth layers of a cloth material; and   a second joining layer, disposed between the third and fourth layers of the cloth material, to join the third and fourth layers of the cloth material.   
     
     
         40 . The article of  claim 39 , wherein the first joining layer and the second joining layer comprise at least one of glue or plastic. 
     
     
         41 . The article of  claim 40 , wherein the first layer of the cloth material coated on first and second sides comprises a coating of glue. 
     
     
         42 . The article of  claim 40 , wherein the first layer of the cloth material coated on first and second sides comprises a coating of plastic. 
     
     
         43 . The article of  claim 39 , wherein the first layer of the cloth material coated on the first and second sides comprises fiberglass mesh. 
     
     
         44 . The article of  claim 39 , further comprising a release layer proximate the fourth cloth layer, the release layer to expose an adhesive to permit coupling of the water resistant underlayment portion to a structure. 
     
     
         45 . The article of  claim 44 , wherein the structure comprises a roof having a pitch. 
     
     
         46 . The article of  claim 45 , wherein the roof comprises a pitch of at least 4-12. 
     
     
         47 . The article of  claim 46 , wherein the water resistant underlayment portion is disposed in a single sheet over the structure. 
     
     
         48 . An article comprising:
 a water resistant underlayment portion, wherein the water resistant underlayment portion consists essentially of:   first and second layers of a cloth material;   a first film layer, disposed between the first and second layers of the cloth material and comprising at least one of glue or plastic, the first film layer to join the first and second layers of the cloth material; and   a first layer of a fiberglass mesh material coated on first and second sides with a film of at least one of glue or plastic.   
     
     
         49 . The article of  claim 48 , further comprising third and fourth layers of a cloth material, the third and fourth layers joined via a material comprising at least one of glue or plastic, the third and fourth layers of the cloth material being beneath the first layer of the fiberglass mesh material. 
     
     
         50 . The article of  claim 49 , wherein the third and fourth layers of the cloth material, joined via the material comprising at least one of glue or plastic, form a vapor barrier.
