Claims15
A roof system, comprising:
- a roof deck including a plurality of fluted panels, each of the plurality of fluted panels including at least one upper flute and at least one lower flute, wherein at least one lower flute of adjacent fluted panels of the plurality of fluted panels are arranged in an overlapping relationship to form at least one overlapped lower flute;
- a layer of weighted cover board disposed upwardly adjacent and in direct contact with an upper surface of the roof deck, the layer of weighted cover board including a plurality of panels of weighted cover board formed from a composite material, each of the plurality of panels of weight cover board being waterproof, wherein a plurality of joints is formed between adjacent panels of the plurality of panels of weighted cover board;
- a sealant arranged within the plurality of joints, the sealant being configured to waterproof said plurality of joints;
- a layer of insulation positioned between the roof deck and the layer of weighted cover board, the layer of insulation being arranged at only the at least one overlapped lower flute of the plurality of fluted panels;
- an adhesive arranged at an upper surface of the roof deck for coupling the layer of weighted cover board to the roof deck, wherein said adhesive and said sealant are an identical material;
- and
- a waterproofing membrane positioned at an uppermost surface of the roof system;
- and
- a layer of insulation positioned above an upper surface of the layer of weighted cover board.

A method of forming a roof system, comprising:
- installing a roof deck, the roof deck comprising a plurality of fluted panels arranged in an overlapping relationship, each of the plurality of fluted panels having at least one upper flute and at least one lower flute, wherein at least one lower flute of adjacent fluted panels of the plurality of fluted panels are arranged in an overlapping relationship to form at least one overlapped lower flute;
- applying an adhesive to at least one of the roof deck and a layer of weighted cover board, wherein the layer of weighted cover board including a plurality of panels of weighted cover board formed from a composite material that is moisture resistant and mold resistant, and wherein a plurality of joints is formed between adjacent panels of the plurality of panels of weighted cover board;
- positioning the layer of weighted cover board upwardly adjacent and in direct contact with a surface of the at least one upper flute of the roof deck such that the adhesive couples the layer of weighted cover board to the roof deck;
- sealing the plurality of joints with a sealant, the sealant being configured to waterproof said plurality of joints, the sealant and the adhesive being an identical material;
- installing a layer of insulation at a position between the roof deck and the layer or weighted, the layer of insulation being arranged at only the at least one overlapped lower flute of the plurality of fluted panels;
- installing another layer of insulation at a position above an upper surface of the layer of weighted cover board;
- and
- installing a waterproofing membrane at an uppermost surface of the roof system.
