Disclosed herein is a roof attachment assembly for mounting a solar panel on a roof without the use of rails. The assembly includes a flashing member, a pivot bracket member, a clamp member, an array skirt and a splice member. The flashing member anchors the roof attachment assembly to the roof. The pivot bracket member is rotatably connected to the flashing member. The clamp member is connected to the pivot bracket member and is rotatably connected thereto. The clamp member includes grounding elements for electrically grounding the solar panel. The array skirt is removably connected to the clamp member. The splice member includes grounding elements for electrically grounding the solar panel and is removably connected to the array skirt. Also disclosed is a method of using the assembly and an assembly kit.

The present invention relates to a novel and improved roof flashing assembly for use in supporting hardware needed to install solar panel arrays on shingle roofs. The assembly is both easy to install and provides an improved watertight seal at the location where the assembly is secured to the rafters of the roof over the state of the art.

Photovoltaic mounting systems that form chemical flashings are provided herein. Such mounting systems can include a mounting plate adapted to interface with an off-the-shelf mounting puck so as to allow mounting of the puck on the roof surface without use of traditional roof flashing and/or modification of shingles of the roof surface. Such mounting plates can include a top surface adapted to interface with the puck and a bottom surface that defines a cavity between the mounting plate and the puck in which to form the chemical flashing by injecting a flowable sealant into the cavity via an inlet of the mounting plate that remains accessible from outside the puck during mounting. Such mounting plates can further include features for orienting the plate, directing runoff away from any sealed roof penetrations and filling of the cavity with flowable sealant.

A photovoltaic module comprising: a base plate and a photovoltaic laminate that are connected together; wherein the photovoltaic module is configured to be directly connected to a roofing structure and provide roofing functions, and wherein the photovoltaic laminate is removable from the base plate without damaging the base plate and the base plate retains its roofing functions when the photovoltaic laminate is removed.

Disclosed herein is a roof mount installation assembly. The roof mount installation assembly includes a roof mount, a flashing patch, and an adapter cap. The roof mount has a base and a threaded post. The flashing patch has an opening. The flashing patch is configured to surround the base. The opening is configured to allow the threaded post to extend therethrough. The adapter cap is configured to be removably mounted over the flashing patch. The adapter cap is configured to apply a force to the flashing patch for sealing the flashing patch around the roof mount.

A method for installing a solar collector can include slip-forming a concrete track including a groove; curing the concrete track; placing a foot of a support structure of a solar collector in the groove; and applying adhesive between the foot and groove. Curing the concrete track optionally can include maintaining wetness of the concrete track for a sufficient period of time after slip-forming the concrete track. The foot optionally can include at least one of an aperture and a tab, and the adhesive flows through the aperture or around the tab. A foot of a support structure of a solar collector also is provided. The foot can be configured to be inserted into a groove and comprising a back wall, a first side wall including a first side tab, a second side wall including a second side tab, a third side wall, a fourth side wall, and a bottom wall.

A building rooftop mounting structure including a sacrificial material that allows freedom of movement between itself and the rooftop as well as between itself and the mounting structure.

A roof integrated photovoltaic system includes a starter bar having a foot base and configured to be installed to a roof deck, a plurality of water shedding layers, and a photovoltaic module. One of the plurality of water shedding layers is configured to be installed over the foot base of the starter bar, and one of another of which is configured to overlap and be installed over the one of the plurality of water shedding layers. The system further includes a foot module configured to be attached to an upper portion of the photovoltaic module. A lower portion of the photovoltaic module is configured to align with the foot base of the starter bar, and the foot module is configured to be affixed on a last overlapping layer of the plurality of water shedding layers to the roof deck.

A mount assembly is provided for mounting a structure to a roof having a top surface. The mount includes a flashing including an aperture; a bracket including a first portion and a second portion, the first portion having an opening and a countersink extending around the opening, the second portion extending at an angle away from the flashing, the second portion including a slot configured to be coupled to the structure; a fastener extending through the aperture and through the opening of the bracket; and a seal extending around the aperture and positioned between the flashing and the first portion of the bracket, the seal engaging the countersink of the bracket and being compressed against the flashing.

A roof mount assembly mounts a structure to a roof having a rafter and a substrate supported by the rafter. The roof mount assembly includes a piece of flashing positioned on the substrate. The flashing includes a first surface, a second surface opposite the first surface and an aperture extending through the flashing. A fastener extends through the flashing aperture. A bracket is connected to the flashing via the fastener, and the bracket is sized to support at least one roof-mounted structure on the roof. A seal is positioned between the flashing aperture and the fastener. The seal is sized to form a water-tight seal with the aperture to inhibit flow of fluid through the aperture. The seal includes a first portion and a second portion, in which the first portion is positioned to abut the flashing first surface and the second portion is positioned to extend through the aperture.
