Hybrid layered structure, method and system including same

Abstract

Some embodiments of the present disclosure relate to methods and roofing systems including a hybrid layered structure. In some embodiments, the hybrid layered layer structure, method, and system are used for waterproofing at least one steep slope roof substrate. In some embodiments, the at least one steep slope roof substrate at least one protruding member protruding from the at least one steep slope roof substrate. In some embodiments, the hybrid layered structure comprises a first coating layer, a roofing membrane, and a second coating layer.

1 . A method comprising:
 obtaining a roofing membrane;   obtaining a liquid applied roofing formulation;   applying the liquid applied roofing formulation to at least one flashing area of at least one steep slope roof substrate so as to form a first coating layer on the at least one flashing area,
 wherein the at least one steep slope roof substrate comprises:
 at least one protruding member,
 wherein the at least one protruding member protrudes from the at least one steep slope roof substrate; and 
 
 the at least one flashing area,
 wherein the at least one flashing area comprises an interface between the at least one steep slope roof substrate and the at least one protruding member; 
 
 
   covering the at least one steep slope roof substrate with a roofing membrane, so as to form a hybrid layered structure on the steep slope roof substrate,   wherein the hybrid layered structure comprises:   the first coating layer; and   the roofing membrane.   
     
     
         2 . The method of  claim 1 , wherein the at least one flashing area of the at least one steep slope roof substrate comprises:
 a first flashing area,
 wherein the first flashing area comprises a first protruding member and a first interface between the roofing membrane and the first protruding member; and 
   a second flashing area,
 wherein the second flashing area comprises a second protruding member and a second interface between the roofing membrane and the second protruding member; and 
   wherein the method further comprises:
 applying the liquid applied roofing formulation to the second flashing area so as to form a second coating layer on the second flashing area; and 
   wherein the hybrid layered structure comprises:   the first coating layer;   the roofing membrane; and   the second coating layer.   
     
     
         3 . The method of  claim 1 , wherein the liquid applied roofing formulation comprises at least one resin. 
     
     
         4 . The method of  claim 3 , wherein the at least one resin is chosen from polysiloxane, polyurea, polyurethane, silane modified ether, silane modified ester, silane modified polyurethane, silane modified polyurea, epoxy resin, acrylic resin, polyacrylic resin, any precursor thereof, or any combination thereof. 
     
     
         5 . The method of  claim 3 , wherein the at least one resin is present in an amount ranging from 20% to 100% based on a total weight of the liquid applied roofing formulation. 
     
     
         6 . The method of  claim 1 , wherein the liquid applied roofing formulation has a viscosity ranging from 100 cP to 10 million cP at 25° C. measured using a Brookfield viscometer at 20 rpm. 
     
     
         7 . The method of  claim 2 , wherein the roofing membrane is disposed over the second coating layer. 
     
     
         8 . A roofing system comprising:
 at least one steep slope roof substrate, wherein the at least one steep slope roof substrate comprises:
 at least one protruding member,
 wherein the at least one protruding member protrudes from the at least one steep slope roof substrate; 
 
 at least one flashing area,
 wherein the at least one flashing area comprises an interface between the at least one steep slope roof substrate and the at least one protruding member; and 
 
 a hybrid layered structure, wherein the hybrid layered structure comprises:
 a first coating layer,
 wherein the first coating layer is disposed over the at least one flashing area; and 
 
 a roofing membrane,
 wherein the roofing membrane is disposed over the first coating layer. 
 
 
   
     
     
         9 . The roofing system of  claim 8 , wherein the at least one flashing area of the at least one steep slope roof substrate comprises:
 a first flashing area,
 wherein the first flashing area comprises a first protruding member and a first interface between the roofing membrane and the first protruding member; and 
   a second flashing area,
 wherein the second flashing area comprises a second protruding member and a second interface between the roofing membrane and the second protruding member; and 
   wherein the roofing system further comprises a second coating layer, wherein the second coating layer is disposed over the at least one second flashing area, and wherein the hybrid layered structure comprises:   the first coating layer;   the roofing membrane; and   the second coating layer.   
     
     
         10 . The roofing system of  claim 8 , wherein the roofing membrane is disposed over the second coating layer.
