A multi-layered integrated roofing plank or panel with a base layer comprising engineered or manufactured wood, a water resistant barrier layer covering at least the outer face of the base layer, and at least one of the edges of the base layer. A texturizing material also may be affixed to, or integrated with, the water resistant barrier layer. The edges of the roofing plank or panel may be configured as part of a joint with adjacent planks or panels, including, but not limited to, shiplap joints, tongue-and-groove joints, bead-and-cove joints, butt joints, or combinations or variations thereof.

A connecting system for boards, and a connecting device and a support element for boards are disclosed. The connecting system includes the support element configured to support at least one board and the connecting device configured to releasably fasten the at least one board to the support element. The support element includes at least one lateral surface with at least one locking member arranged on the lateral surface. The connecting device includes at least one arm with a locking member configured for engagement with the locking member of the support element. At least one of the locking member of the support element and the locking member of the connecting device includes a plurality of protrusions forming a plurality of locking positions of the connecting device relative the support element.

A foam backed panel comprised of a cladding with polyurethane foam is anchored to a frame by an anchor embedded in the foam and straps attaching the anchor to frame members. The anchored frame enables 100% continuous insulation since it eliminates nails and other fasteners that cause thermal bridges. Anchors also increase a panel's uplift resistance and may be used to attach roof panels to trusses. This all results in a stronger, better insulated structure.

Roofing panels with water shedding features may be installed on the roof of a house or other structure in lieu of or as an underlayment for traditional roofing materials. The water shedding features can be built into a base of the roofing panels, as part of a frame for the roofing panels, or formed as part of a waterproofing layer applied to the base of the roofing panels, or which can be configured as a roofing panel. The roofing panels also can be installed in overlapping courses along a roof with water shedding features applied thereto or incorporated along one or more peripheral edges. The water shedding features of adjacent roofing panels will collect and divert water away from the upper surfaces and/or away from headlap and/or sidelap joints defined between the roofing panels.

A method may include placing a bottom facer on a conveyor, placing a core layer on the bottom facer placing a top facer on the core layer, and pressing the bottom facer, the core layer, and the top facer in a hot press to form a panel, wherein the hot press causes the bottom facer to shrink relative to the top facer, introducing a warp into the panel such that, when installed, the warp compensates for an installation warp and the panel is flat upon installation.

A method for producing a covering element made from natural fibres, in particular cellulose, impregnated with bitumen, includes a step of coating at least one of two faces of a fibre mat (4) followed by a step of impregnating with bitumen, the coating being carried out with a liquid composition (5) including at least one resin and/or at least one pigment. The liquid composition is a dye composition including at least one pigment and at least one resin, and the method involves adding an additive to the liquid composition (5), the additive having fireproof properties and including at least graphite and a cooling agent. Preferably, the mat (4) is coated with the liquid composition including the fireproof additive using a roller.
