The present disclosure relates particularly to photovoltaic roofing systems for use in photovoltaically generating electrical energy, specifically, the use of bottom flashings in such systems. Methods for installing such systems and replacing non-photovoltaic roofing elements in such systems are also described.

Photovoltaic roofing systems with bottom flashings

The present disclosure relates generally to a roofing system including flashing, for example, suitable for protecting a roof from water leakage. The present disclosure relates more particularly to a roofing system including first, second, and third courses of shingles, where the second course overlaps the first and the third course overlaps the second. A flashing plate is disposed over the first course of shingles and partially under the second course of shingles. The flashing plate and the third course of shingles are spaced apart by a gap in a direction of the slope of the roof between a top edge of the flashing plate and a lower edge of the third course of shingles.

Short penetration flashing, flashing systems and methods for installing them

The present invention relates generally to electrical systems. The present invention relates more particularly to electrical wiring systems suitable for use in roofing applications. One aspect of the invention is a wiring system on a roof comprising a roof deck having a slope and one or more roofing elements disposed on the roof deck, the wiring system including one or more wires extending along the roof on top of the roofing elements; and a wire covering disposed over the one or more wires.

Electrical wiring systems for use in roofing applications

The present invention relates particularly to photovoltaic roofing products for use in photovoltaically generating electrical energy and provides inside corner flashings useful for flashing photovoltaic roofing systems in which photovoltaic roofing elements are disposed in a staggered configuration.

Photovoltaic roofing systems with inside corner flashings

The present invention relates more particularly to improved flashings for use in integrating specialized roof-mounted structures, such as photovoltaic devices for the generation of electrical energy, with conventional roofing materials on a roof. In one aspect, the invention provides a flashing element having a cross-sectional shape comprising a laterally-extending flange, the flange having an edge, a first end and a second end, the side flashing element comprising a return hem disposed at the edge and comprising a folded-over strip of material disposed over the top surface of the flange at the edge, the return hem having a first end disposed toward the first end of the edge, and a second end disposed toward the second end of the edge, wherein the total thickness of the return hem at its second end is no greater than the interior thickness of the return hem at its first end.

Roofing flashings and roofing systems and photovoltaic roofing systems using the same

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.

Photovoltaic roofing elements and photovoltaic roofing systems

Photovoltaic roofing systems with inner corner flashings

The present invention relates generally to photovoltaic systems. The present invention relates more particularly to photovoltaic roofing systems in which photovoltaic elements are disposed upon roofing elements such as shingles, tiles, shakes or slates. For example, in one embodiment, the present invention provides a photovoltaic roofing system for use on a roof deck, the photovoltaic system including a plurality of horizontally-arranged first photovoltaic roofing elements disposed on the roof deck, each having a top end and a bottom end; one or more first flashing elements disposed on the roof deck upwards from the first photovoltaic roofing elements, the first flashing element having a top end, and a bottom end overlapping the top end of one or more of the first photovoltaic roofing elements; and a plurality of horizontally-arranged second photovoltaic roofing elements disposed on the roof deck upwards from the one or more first flashing elements, each second photovoltaic roofing element having a top end, and a bottom end overlapping the top end of one or more of the first flashing elements, the second photovoltaic roofing elements not overlapping the bottom end of any of the first flashing elements.
