Watertight fastening devices and systems and methods for the employment thereof are disclosed. The disclosed watertight fastening device includes a head, a shank extending away from the head toward a distal end, and a cover extending outwardly and away from the head in the direction of the shank and defining a hollow region between the shank and an inner surface of the cover. The watertight fastening device may be used in conjunction with a solar power installation system that includes a base plate configured to be positioned against an installation surface. The base plate includes an aperture for receiving the shank of the fastener and protrusion surrounding the aperture configured to be received in the hollow region of the fastener, thereby providing an enhanced barrier against moisture reaching the installation surface.

Embodiments of the present invention provide rigid attachment of materials using a roof mount, a cover, and a resilience constituent. A roof mount may have a top roof mount and bottom roof mount. A resilience constituent may be a ring, a disk with a middle ridge or even an arched disk or the like.

A tile replacement flashing is used with a tile hook. A bottom tile replacement flashing is shaped for placement on a lower portion of a location where a tile is removed from a roof. A top tile replacement flashing is shaped for placement on an upper portion of a location where the tile is removed from the roof. The top tile replacement flashing includes an elevated region at a lower portion of the top tile replacement flashing, the elevated region. The bottom tile replacement flashing is shaped so that after attachment of the bottom tile replacement flashing on the roof, the tile hook can be attached to a rafter of the roof, the attached tile hook extending over an upper portion of the bottom tile replacement flashing and having a portion that, past the upper portion of the bottom tile replacement flashing, extends upwards. The top tile replacement flashing is shaped so that after attachment of the top tile replacement flashing on the roof, at least part of the elevated region of the top tile replacement flashing extends over the bottom tile replacement flashing. A height of the elevated region is sufficient to allow room for the tile hook to extend over the bottom tile replacement flashing and under the elevated region of top tile replacement flashing.

Embodiments of the present invention provide rigid attachment of materials using a roof mount, a cover, and a resilience constituent. A roof mount may have a top roof mount and bottom roof mount. A resilience constituent may be a ring, a disk with a middle ridge or even an arched disk or the like.

A roof pan with raised ridges along lateral edges, where the raised ridges of one pan cooperate raised ridges of another pan to prevent water movement. A formed edge that is offset from the roof surface when the pan is installed on the roof allows a flashing to slide under the formed edge when the roof pan is installed on the roof surface.

A mounting bracket (320) for trapezoidal rib profiles is disclosed. This mounting bracket (320) includes an upper section (330) and a lower section (350). A first leg (352a) in a second leg (352b) extend from a lower portion of the upper section (330) in diverging relation to one another. Each of these legs (352a, 352b) is deflectable through a certain range of motion to accommodate installation of the mounting bracket (320) on a variety of different trapezoidal rib profiles.

The present disclosure provides photovoltaic (PV) module mounting systems and bracket assemblies for securing PV modules to roofs. The photovoltaic module mounting systems may include a roofing panel having a base layer, a flashing panel coupled along an edge of the roofing panel, and a bracket assembly coupled to the roofing panel, where the bracket assembly includes a bracket and a clip, and where the clip is configured to couple with an edge feature of a PV module to secure the PV module to the roofing panel.

The present disclosure provides junction boxes for use with roof-mounted photovoltaic (PV) modules. The junction boxes may include a housing having a plurality of sides, a bottom having an aperture, and a top edge having a top opening, where the top edge has a lip disposed around the top edge and projecting upward from the top edge. The junction boxes may further include a lid removably coupled to the top edge of the housing and a seal disposed on an outer surface of the bottom of the housing.

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.
