Flashing assemblies prepared with liquid flashing compositions
One or more embodiments of the present invention provide A roofing system comprising (i) a roof deck; (ii) a vertical structure extending from said roof deck; (iii) a membrane system covering said roof deck; and (iv) a flashing assembly creating a water-proof seal between said membrane system and said vertical structure, where said flashing assembly includes a flashing composite having a polymeric membrane component and a fabric component, said polymeric membrane component being bonded to said membrane system, and said flashing assembly further including a cured residue layer of a liquid flashing composition extending from said fabric component of said fleeced flashing membrane to a surface of said vertical structure, and said cured residue being bonded to said fabric component and said surface of said vertical structure.
1. A roofing system comprising:
(i) a roof deck;
(ii) a vertical structure extending from said roof deck;
(iii) a membrane system covering said roof deck, said membrane system including a polymeric membrane; and
(iv) a flashing assembly creating a water-proof seal between said membrane system and said vertical structure, where said flashing assembly includes a flashing composite having a generally planar polymeric membrane component having first and second planar surfaces, and a fabric component attached to said first planar surface of said membrane component, said second planar surface of said polymeric membrane component being bonded to said polymeric membrane of said membrane system such that the bond between the second planar surface of the polymeric membrane component and said polymeric membrane of said membrane system is opposite said fabric, and said flashing assembly further including a cured residue layer of a liquid flashing composition forming an outermost layer of the flashing assembly and extending from said fabric component of said flashing composite to a surface of said vertical structure, and said cured residue being embedded within and bonded to said fabric component and bonded to said surface of said vertical structure.
2. The roofing system of claim 1 , where said membrane system and said membrane component of said flashing composite are thermoplastics, and where said membrane component of said fleeced flashing membrane is thermally bonded to said membrane system.
3. The roofing system of claim 1 , where said membrane system is a thermoset rubber, where said membrane component of said flashing composite is a thermoset rubber, and where said membrane component of said flashing composite is bonded to said membrane system through an adhesive.
4. The roofing system of claim 1 , where said cured residue layer of a liquid flashing composition is the cured residue of a one-part polyurethane composition.
5. The roofing system of claim 1 , where said cured residue layer of a liquid flashing composition is the cured residue of a two-part polyurethane composition.
6. The roofing system of claim 1 , where said cured residue layer of a liquid flashing composition is a polymethyl methacrylate.
7. The roofing system of claim 1 , further comprising a fabric reinforcement within said cured residue layer.
8. The roofing system of claim 1 , where said fabric is a fleece.
9. The roofing system of claim 1 , where said residue of a liquid flashing composition is a silicon-container polymer.
10. The roofing system of claim 1 , where said fabric has a generally planar configuration with oppositely facing first and second planar surfaces, where said first planar surface of said fabric is bonded to said membrane component, and where the residue of said liquid flashing completely covers the second planar surface of said fabric.
11. The roofing system of claim 1 , where said roof deck and said vertical structure form an intersection where said roof deck and said vertical structure meet, and where said flashing composite, which is bonded to said membrane system, terminates at or prior to said intersection.
