Claims
- 1. A method for providing a roof structure having a plurality of trusses spaced apart from one another in a parallel arrangement, the trusses having top portions, respectively, the method comprising:
- a. paying out a support sheet so that the support sheet depends from the top portions of adjacent trusses;
- b. applying flexible insulation material above the support sheet so that the flexible insulation material is supported by the support sheet;
- c. fastening metal deck sheets to the top portion of the trusses to form a metal deck; and
- d. applying a temporary waterproofing sealant to the metal deck to protect the flexible insulation material.
- 2. The method of claim 1 further comprising subsequently applying a waterproof membrane above the metal deck to provide a permanently waterproofed roof structure.
- 3. The method of claim 1 further comprising applying rigid insulation board on top of the metal deck sheets.
- 4. The method of claim 1 further comprising subsequently applying rigid insulation board on top of the metal deck sheets and then applying a waterproof membrane above the rigid insulation board to provide a permanently waterproofed roof structure.
- 5. The method of claim 1, wherein said sealant is an asphalt and said method further comprises the step of oxidizing the asphalt prior to applying it such that it has a melting point between about 165.degree. F. and about 200.degree. F.
- 6. A method for providing a roof structure having a plurality of trusses spaced apart from one another in a parallel arrangement, the trusses having top portions, respectively, the method comprising:
- a. paying out a support sheet so that the support sheet depends from the top portions of adjacent trusses;
- b. applying flexible insulation material above the support sheet so that the flexible insulation material is supported by the support sheet;
- c. fastening metal deck sheets to the top portion of the trusses to form a metal deck;
- d. applying a temporary waterproofing sealant to the metal deck to protect the flexible insulation material; and
- e. subsequently applying a waterproof membrane above the metal deck to provide a permanently waterproofed roof structure.
- 7. The method of claim 6 in which the waterproof membrane is a built up roof.
- 8. The method of claim 6 in which the waterproof membrane is an ethylene propylene diamine monomer.
- 9. The method of claim 6 comprising applying rigid insulation board to the roof structure, in which the rigid insulation board is positioned between the metal deck and the waterproof membrane.
- 10. The method of claim 9 in which the rigid insulation board includes styrene foam.
- 11. The method of claim 9 in which the rigid insulation board includes glass wool.
- 12. The method of claim 6 in which the support sheet is perforated.
- 13. The method of claim 6 in which the support sheet is payed out from a roll mounted on a carriage which moves along the length of the trusses.
- 14. The method of claim 6 in which the metal deck sheets have edge portions which are fastened to the top portion of the trusses in an overlapping manner, thereby creating a seam.
- 15. The method of claim 14 in which the temporary waterproofing sealant is applied over the seam of the overlapping metal deck sheets.
- 16. The method of claim 14 in which the temporary waterproofing sealant is applied between the edge portions of adjacent metal deck sheets which overlap.
- 17. The method of claim 14 in which a first layer of temporary waterproofing sealant is applied between the portions of the adjacent metal deck sheets which overlap, and a second layer of temporary waterproofing sealant is applied on top of the seam of the overlapping metal deck sheets.
- 18. The method of claim 6 wherein said sealant has a melting point of above about 165.degree. F.
- 19. A method for providing a roof structure having a plurality of trusses spaced apart from one another in a parallel arrangement, the trusses having top portions, respectively, the method comprising:
- a. paying out a support sheet so that the support sheet depends from the top portions of adjacent trusses;
- b. applying flexible insulation material above the support sheet so that the flexible insulation material is supported by the support sheet;
- c. fastening metal deck sheets to the top portion of the trusses to form a metal deck, in which the metal deck sheets have edge portions which are fastened to the top portion of the trusses in an overlapping manner thereby creating a seam;
- d. applying a temporary waterproofing sealant to the metal deck to protect the flexible insulation material;
- e. subsequently applying rigid insulation board on top of the metal deck; and
- f. applying a waterproof membrane on top of the rigid insulation board to provide a permanently waterproofed roof structure.
- 20. The method of claim 19 in which the temporary waterproofing sealant is applied on top of the seam.
- 21. The method of claim 19 in which temporary waterproofing sealant is applied between the edge portions of adjacent metal deck sheets.
- 22. The method of claim 19 in which a first layer of temporary waterproofing sealant is applied between the edge portions of metal deck sheets, and a second layer of temporary waterproofing sealant is applied on top of the seam.
- 23. The method of claim 19, wherein said sealant is an asphalt, said method further comprising oxidizing the asphalt prior to applying it so that it has a melting point between about 165.degree. F. and about 200.degree. F.
