Abstract

A shingle system for covering sloping roofs and also capable of being used as wall sidings. The shingles are made of heat-insulating material and each main shingle has at its underface a network of intersecting channels communicating with the channels of adjacent shingles for ventilation of the space between the support surface and the shingles, to prevent water condensation. The shingles are laid in cross-rows and longitudinal rows and have keys to interlock adjacent shingles along both rows. The shingles have water barriers at their top face to prevent wind-swept rainwater from entering the joints between adjacent shingles and from overflowing onto the support surface. Concealed passageways are provided to allow this water to run off the shingles. Ridge shingles and side edge shingles are also provided to prevent rain from reaching the support surface, while permitting air circulation between the shingles and the support surface. A fascia board is also provided for the same purpose.

Claims

1. A shingle consisting of a one-piece quadrangular body, made of insulating material, having a flat underface, a body top face, a front and a back edge face substantially parallel to each other, a right-hand and a left-hand side edge face generally parallel to each other, said shingle of decreasing thickness from said front to said back edge face, said underface having intersecting channels opening at all said edge faces;

a back and a right-hand peripheral flange upstanding from said body top face adjacent said back edge face and said right-hand side edge face, respectively, and interconnected at a back right-hand corner defined by the junction of said back edge face with said righthand side edge face, each peripheral flange having a top face and an inner upstanding face joining with said body top face;

the top face of said back peripheral flange defining fastening areas to fasten said shingle to an underlying support surface;

said front and back edge faces at least partially forwardly and downwardly inclined at substantially the same angle relative to said underface;

said body top face extended by a front marginal extension of said body which overhangs said front edge face and which has an underface;

said body top face extended by a lefthand side marginal extension of said body which overhangs said left-hand side edge face;

said left-hand side marginal extension and the left-hand part of said front marginal extension forming a rib upstanding from said body top face and extending from the front edge of said front marginal extension to said back edge face, said rib having a free edge face, said back flange also upstanding from the rear end of said rib;

the portion of said rib defining said left-hand side marginal extension and said left-hand part of said front marginal extension having an underface which is substantially co-planar with the top face of said right-hand peripheral flange and with the top face of said back peripheral flange adjacent said right-hand peripheral flange;

said rib tapering from front to back of said body an amount about equal to the thickness of said left-hand part of said marginal extension, said front and left-hand marginal extensions having a front dependent flange and a left-hand dependent flange downwardly protruding from the underface of said marginal extensions, respectively, said front- and left-hand dependent flanges each having an inner face joining with the underface of said front marginal extension and with the underface of said left-hand marginal extension, respectively;

the spacing, in a plane parallel to said body top face, between the inner face of said front dependent flange and said front edge face being greater than the spacing, in a plane parallel to said body top face, between the inner face of said back flange and said back edge face, the spacing, in a plane parallel to said body top face, between the inner face of said left-hand dependent flange and said left-hand side edge face being greater than the spacing, in the plane parallel to said body top face, between the inner face of said right-hand upstanding flange and said right-hand side edge face;

said rib having a notch made in its free edge face adjacent and forwardly of said back flange;

said right-hand peripheral flange terminating at its front end short of the front edge of said front marginal extension, the right-hand part of said front marginal extension and the front portion of said right-hand side edge face forming a recessed side edge face portion;

said shingle adapted to form with three other identical shingles an array of four adjacent shingles which, when in service, have their underface flatly resting on a sloping or vertical support surface, with said front and back edge face of each shingle of said array at a substantially constant lower level and higher level, respectively, with a first lower shingle and a second upper shingle aligned in the same left-hand longitudinal row in the sloping direction, and with a third lower shingle and a fourth upper shingle aligned in the same right-hand longitudinal row in the sloping direction, with said first and third lower shingles aligned in the same lower cross-row transverse to said sloping direction and with said second and fourth shingles aligned in the same upper cross-row transverse to said sloping direction, said second and fourth shingles have their front edge face abutting and interlocking with the back edge face of said first and third shingles, respectively, and said second and fourth shingles have their front marginal extension overlapping said back flange of said first and third shingle, respectively, the left-hand edge face of said third and fourth shingles abutting the right-hand edge face of said first and second shingles, respectively, said left-hand marginal extension of said third and fourth shingles overlapping said upstanding right-hand flange of said first and second shingles, respectively, the front dependent flange of said second and fourth shingles contacting the top face of said first and third shingles, respectively, the left-hand dependent flange of said third and fourth shingles contacting the top face of said first and second shingles respectively, with the inner faces of each pair of front and back flanges and of each pair of right-hand upstanding flange and left-hand dependent flange spaced from each other to define a back concealed passage at the back of said first and third shingles, and a side concealed passage along the left-hand side of said first and second shingles, said back and side passages intercommunicating at the back right-hand corner of said first shingle and with the notch of said third shingle, the side passage along said second shingle being closed at its forward end by the front dependent flange of said fourth shingle and communicating with said notch of said third shingle around the front end of the right-hand upstanding flange of said second shingle, said last-named notch in turn communicating the side concealed passage of said first shingle and overlapped by said left-hand part of said front marginal extension;

said recessed side edge face portion of said second shingle receiving the rear end portion of the free edge face of the rib of said third shingle to permit alignment of said second and first shingles in the left-hand longitudinal row and overlapping of said first shingle by said second shingle.

2. A shingle as defined in claim 1, wherein said top face is flat and said rib upstands from said top face end has an external surface which is of cross-sectionally trapezoidal shape.

3. A shingle as defined in claim 2, provided at the back lefthand corner with a stop member downwardly protruding from the underface of its left-hand marginal extension, said shingle being provided at its back right-hand corner with a notch made in said back edge face and in said right-hand corner with a notch made in said back edge face and in said right-hand side edge face, said notch adapted to receive the stop of an adjacent right-hand shingle in the same cross row to align the two shingles in said same cross row.

4. A shingle as defined in claim 2, wherein the inner face of said back upstanding flange makes a right angle with said body top face and the inner face of said front dependent flange is downwardly forwardly inclined.

5. A shingle as defined in claim 4, wherein the inner face of said right-hand upstanding flange makes a right angle with said body top face.

6. A shingle as defined in claim 3, wherein the portion of said front dependent flange, which depends from the front end of said rib, has a contour for contacting the external surface of the rear end of the rib of a lower shingle in the same longitudinal row.
