A method and system for adhering roofing products to a supporting roof substrate, wherein ballast rock from a pre-existing roof insulation system is removed thereby exposing one or more layers of pre-existing insulation products supported by the roof substrate. In the case of new construction, the method contemplates installation of one or more layers of insulation products supported by the roof substrate. Core holes are formed through the one or more layers of insulation products thereby exposing the roof substrate. An anchor is attached to the roof substrate in each core hole void, and a binding agent is applied to each core hole void until the binding agent fills the core hole void, whereby the one or more layers of insulation products and roof substrate are locked together, preventing shifting of the insulation products without the need for adding ballast rocks thereon

A framing assembly has at least one rafter vent assembly having a connecting member with a plurality of vent tubes for providing supplemental ventilation and additional structural support to a frame of a building structure. The at least one rafter vent assembly may be an interior rafter vent assembly or an exterior rafter vent assembly. The interior rafter vent assembly has at least one brace member and a connecting member, with the connecting member having a connecting plate, two end plates, and the plurality of vent tubes. The exterior rafter vent assembly has the connecting member that has a connecting plate and the plurality of vent tubes. The framing assembly also preferably has a plurality of modified structural insulated panels (SIPs) and modified rafter splines.

The present disclosure provides a sump drain apparatus comprising a drain inlet and a ramp coupled to the drain inlet comprising an incline plane configured to divert drainage water toward the drain bowl, wherein at least a portion of the ramp is configured to be positioned on top of a roof deck.

Support members for a roof system are provided to allow for positioning panels of a roof apart from building members so that building components, such as insulation may be placed between the roof panels and the building members. The support members may be utilized in new buildings or to retrofit existing buildings. Each of the support members may comprise a single support member that has a base portion operatively coupled to an offset portion that is operatively coupled to an upper portion. One or more channels may be provided in the base portion, offset portion, and/or the upper portion to provide structural support and to allow the support members to be operatively coupled to each other and other building members without the need for additional components.

A cover board and roofing system including a cover board are disclosed. In one embodiment, the cover board includes a honeycomb layer positioned between a first face sheet and a second face sheet. The honeycomb layer comprises a honeycomb structure having a plurality of partition walls forming a plurality of cells. When the cover board is applied as part of a roof structure, including an insulation layer and a roof deck below the cover board, the roof structure exceeds requirements for Very Severe Hail Resistance according to the FM Approvals FM 4470 VSH impact resistance testing standard for Single-Ply, Polymer-Modified Bitumen Sheet, Built-Up Roof (BUR) and Liquid Applied Roof Assemblies.

A cover board and roofing system including a cover board are disclosed. In one embodiment, the cover board includes a core having a first surface and a second surface. The core is configured to overlie a roof substrate. The cover board includes at least one facer attached to the first surface, the second surface, or both the first surface and second surface of the core. The cover board includes a reinforcing layer positioned between the core and the at least one facer. The reinforcing layer may comprise a scrim material. An impact resistance of the cover board may be greater than an impact resistance of an identical cover board without the scrim material.

The disclosure relates to a roofing system for a flat roof or a flat inclined roof of a building with a thermal and/or acoustic insulation, consisting of a structural support, a deck, optionally a vapour control layer, a waterproof membrane and at least one insulation element being a bonded mineral fibre product made of mineral fibres, preferably stone wool fibres, and a cured aqueous binder, whereby the cured aqueous binder prior to curing comprises a component (i) in form of one or more oxidized lignins, a component (ii) in form of one or more cross-linkers, a component (iii) in form of one or more plasticizers, and whereby the insulation element has a bulk density between 70 kg/m.sup.3 and 250 kg/m .sup.3.

A roof product has a thermal heat storage layer, a vent layer with channels for transferring excess heat through a length of the roof product, and a flame retardant to suppress fire through the vent layer. These three materials form a unitary structure. The roof product may have a radiant layer, the thermal heat storage layer and the vent layer to form the unitary structure. The roof products are assembled in an abutting configuration on the roof of a building. The vent layer vents excess heat from an eave of the roof up to a ridge of the roof and out to atmosphere. The roof products manage thermal energy in the roof by storing thermal heat with the unitary roof product during a heating cycle; venting excess heat through the unitary product; and releasing the stored thermal heat from the unitary product into or out of the building during a cooling cycle.
