Abstract
Interlocking roof shingle has a front rounded tongue on the first side edge; a tongue on the first end edge; an elongated groove assembly on the upper surface with a groove defined therein; a groove in the second end edge of the body; a groove in the second side edge of the body; and an elongated tongue assembly on the lower surface. In an embodiment of the invention, the front rounded tongue of an upper roof shingle is inserted into the elongated groove assembly of a lower roof shingle while at the same time a leg of the elongated tongue assembly of the upper roof shingle enters into a groove in the second end edge of the lower roof shingle for interlocking upper and lower shingles. The tongue on the first end edge is inserted into a corresponding groove in the second end edge of an adjacent roof shingle.

An interlocking roof shingle comprising:
- a body comprising:
- a first side edge, a second side edge, and a transverse axis extending between the first side edge and the second side edge, the first side edge being spaced apart from the second side edge along the transverse axis;
- a first end edge, a second end edge, and a longitudinal axis extending between the first end edge and the second end edge, the first end edge being spaced apart from the second end edge along the longitudinal axis;
- an upper surface and a lower surface;
- a front tongue element extending from the first side edge of the body;
- an elongated groove assembly on the upper surface of the body and having a groove defined therein and extending from the first end edge of the body to the second end edge of the body and defining an area with the second side edge of the body;
- the second end edge of the body having a groove defined therein and extending between the first side edge and the second side edge of the body;
- the second side edge of the body having a groove defined therein and extending between the first end edge and the second end edge of the body;
- a tongue element on the first end edge of the body and extending between the first side edge and the second side edge;
- an elongated tongue assembly located on the lower surface of the body and extending between the first end edge and the second end edge of the body and including a first leg mounted on the lower surface of the body and a second leg spaced away from the lower surface to define an open area in the elongated tongue assembly;
- and
- a plurality of apertures in the area defined between the elongated groove assembly and the second side edge of the body.

- and wherein each roof shingle comprises
- a body which includes a first side edge, a second side edge, a first end edge, a second end edge, a top surface and a lower surface in abutting contact with the roof when the first roof shingle is in place on the roof;
- a front element along the first side edge of the body and extending between the first end edge and the second end edge;
- a tongue element on the first end edge of the body and extending between the first side edge and the second side edge of the body;
- an elongated groove assembly on the upper surface of the body and extending between the first side edge and the second side edge of the body and having a groove defined therein;
- the second end edge of the body having a first groove defined therein and extending between the first side edge and the second side edge;
- the second side edge of the body having a second groove defined therein and extending between the first end edge and the second end edge;
- an elongated tongue assembly located on the lower surface of the body and extending between the first end edge and the second end edge of the body;
- and
- interlocking the first roof shingle with the second roof shingle by sliding the elongated tongue assembly of the first roof shingle into the groove of the elongated groove assembly of the second roof shingle to form an overlapping relationship of the front element of the first roof shingle with the top surface of the second roof shingle.
