A method for providing a roof structure (86) having a plurality of trusses (31) spaced apart from one another in a parallel arrangement is diclosed. The trusses each have a top portion (42). A support sheet (50) is payed out so that the support sheet depends from the top portions of adjacent trusses. Flexible insulation material (54) is applied above the support sheet so that the flexible insulation material is supported by the support sheet. Metal deck sheets (58, 92) are fastened to the top portion of the trusses, thereby forming a metal deck (59). A temporary waterproofing sealant (88, 96) is applied to the metal deck to protect the flexible insulation material, thereby creating a partially completed roof structure (40). Rigid insulation board (82) and a waterproofing membrane (84) are subsequently applied onto the metal deck, thereby forming a completed permanently sealed roof structure (86).

L'invention concerne un procédé de fabrication d'une structure (86) de toit dans laquelle plusieurs fermes (31) sont espacées et disposées parallèlement. Ces fermes comportent chacune une partie supérieure (42). Une feuille de support (50) est déroulée de façon à pendre des parties supérieures des fermes adjacentes. Un matériau isolant flexible (54) est appliqué sur la feuille de support de façon à ce qu'il soit supporté par celle-ci. Les tôles (58, 92) en pont sont fixées à la partie supérieure des fermes, formant un pont métallique (59). Un matériau provisoire (88, 96) étanche à l'eau est appliqué sur le pont métallique pour protéger le matériau isolant flexible, créant ainsi une structure (40) de toit presque complète. Une plaque isolante rigide (82) et une membrane d'étanchéité (84) sont ensuite appliquées sur le pont métallique pour obtenir une structure de toit (86) à étanchéité permanente.
