An interlocking panel system for covering a base surface with interlocking panels to prevent water ingress is provided. A first panel includes a sheet-like section, a receptacle connected to the sheet-like section, a first projection and a second projection. An interlock includes an interlock hook portion and an interlock receiving portion with the interlock configured to be inserted into the receptacle of the first panel and at least one of the interlock hook portion or the receptacle preventing the interlock from being withdrawn from the first panel. A second panel includes a sheet-like portion and a second panel hook portion configured to be inserted into the interlock receiving portion and engage with the second projection of the first panel. At least one of the second panel hook portion or the second projection preventing the second panel from being withdrawn from the first panel and/or interlock.

A roof system includes a roof deck, a weighted cover board disposed upwardly adjacent the roof deck and a plurality of fasteners coupling the weighted cover board to the roof deck.

Interlocking laminated structural roofing panels have a lightweight foamed core sandwiched between outer and inner layers of materials such as wood, polymer materials, fire resistant and/or waterproof membranes, and metal layers. At least one layer is a self-gripping metal sheet that grips and bonds mechanically to adjacent layers such as wood layers. A self-gripping metal sheet may be used on both sides of the roofing panels to form a panel that is strong, structurally robust, and able to span between relatively widely spaced roof rafters with little or no mid-span support. Interlocking features along the edges of the panels interlock adjacent panels together to form a strong monolithic roof covering for a roof.

A metal blocking with coping with cleat having a coping cap with a cap top flange, and first and second side flanges defining first and second channels respectively at respective ends; and a coping cleat having first and second top flanges, a corner anchoring flange, and an intermediate anchoring flange. The first channel is defined by a first exterior cleat strip, a first base cleat strip, and a first interior cleat strip. The second channel is defined by a second exterior cleat strip, a second base cleat strip, and a second interior cleat strip. The first side flange has a first predetermined height and the second side flange has a second predetermined height, wherein the first predetermined height is shorter than the second predetermined height.
