A roof tile comprising a decorative layer, the decorative layer comprising a ceramic body, and a support layer disposed below the decorative layer, wherein the roof tile comprises an upper edge, a lower edge which is opposite to the upper edge and two opposite side edges, the opposite side edges being transverse to the upper edge, wherein the roof tile comprises at least a first coupling elements configured for being coupled to an adjacent roof tile in a roof covering, and wherein the first coupling elements are provided at least at one side edge of the roof tile.

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of the first panel and at least one of the interlock hook portion or the receptacle preventing the interlock from being withdrawn from the first panel.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 At least one of the second panel hook portion or the second projection preventing the second panel from being withdrawn from the first panel and/or interlock.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 roofing system has metal shingles that have formed side lap features that are configured to facilitate alignment of adjacent side lapped metal shingles of a shingle installation along a roofing structure and that couple the metal shingles together and form seals along their side lapped peripheral edges. The metal shingles also can have alignment features that cooperate to align shingles in one course with shingles in a next lower course within their headlap regions.

A roofing system has metal roofing shingles that have formed side lap features that are configured to facilitate alignment of adjacent side lapped metal roofing shingles of a shingle installation along a roofing structure and that couple the metal roofing shingles together and form seals and seams along their side lapped peripheral edges. The metal roofing shingles also can have alignment features that cooperate to align shingles in one course with shingles in a next lower course within their headlap regions. The roofing system also has standing seam features configured to couple to the metal roofing shingles to cover the formed seams.

An interlocking panel system for covering a base surface with interlocking panels to prevent water ingress. A first panel is secured to the base surface. A second panel interlocks with the first panel via a hook portion on the second panel entering a receptacle of the first panel. The hook portion expands after entering a retaining portion of the receptacle, thereby preventing the hook portion of the second panel from being withdrawn from the first panel.

The present concept is a method of roofing a bare roof deck. Asphalt shingles and metal flashings are applied to a wood deck of a roof before flashings and asphalt capping are applied. Metal panels are applied overtop of existing asphalt roof, thereby creating a metal overlay configured such that substantially all of the asphalt shingles are covered with a metal panel for preventing further degradation of asphalt components by shielding from sunlight, UV rays, excessive moisture, snow, wind, ice and fire. No further flashings are installed thereby the metal panel overlay creates a semi-watertight seal wherein the metal panel overlay together with asphalt roof is adapted to create a watertight seal. The present concept is also a method for roofing an existing asphalt shingled roof where metal panels are applied overtop the existing asphalt shingled roof. This creates a metal overlay that covers substantially all of the asphalt shingles for preventing further degradation of asphalt components, and provides a method of preserving an asphalt shingled roof.

A metal shingle having a body with left, right, top and bottom parts. The body is substantially planar and rectangular and has a front, a rear, left and right sides, a top and a bottom. The left and right parts extend from the left and right side respectively. One of the left and right parts is folded over the front and the other is folded over the bottom. The top and bottom parts extend from the top and bottom respectively. One of the top and bottom parts is folded over the front and the other is folded over the bottom. In use, the shingles are positioned in each of side-to-side and top-to-bottom abutting relation so that adjacent sides are interlocked. The body defining a hollow adjacent to one of the interlocking top and bottom parts.

A snow-melting roof tile according to an embodiment of the present invention comprises: a metal roof tile including a main cover part, a first bending part bent vertically and located at a first edge in a first direction of the main cover part and, and a second bending part bent vertically and located at a second edge in the first direction, opposite to the first edge of the main cover part; a heat generation part located an upper portion or lower portion of the metal roof tile; and a fixing part for fixing the heat generation part to the metal roof tile, wherein the heat generation part can generate heat to heat the metal roof tile, thereby melting snow on the metal roof tile.

A device and method for covering a roof. The interlocking roof shingle includes a shingle having a top surface and a bottom surface. A first edge of the shingle is curved over the top surface and a second edge of the shingle is curved under the bottom edge of the shingle. The first edge of the shingle is configured to engage with the second edge of an adjacent shingle. The device further includes a tab configured to receive a nail and engage with the first edge of the shingle. Some embodiments of the shingle are configured to fit along the ridges and valleys of a roof. In these embodiments, the shingle has a center fold and a gap in the upper and lower folded edges.
