Technologies and implementations for a stabilizing support structure system, which may provide vertical and lateral support for a secondary structure over an existing structure. The secondary structure may be a secondary roof, which may be elevated over an existing roof. The secondary structure may be a porch, which may be elevated over an existing roof.

A metal roof flashing system includes a pipe flashing assembly including a triangular base flashing, a rubber vent support, and a lower flashing seal. The pipe flashing assembly is structured to receive a roof vent pipe and form a watertight seal around a plumbing vent stack on a roof surface or side wall of a building. The rubber vent support is flexible and contours to and around the roof vent pipe and form a seal. The pipe flashing assembly is able to be installed on a metal roof surface of a building.

Various roof vent adaptors are disclosed. The roof vent adaptors can be used to seal penetrations on buildings, such as vent penetrations on metal or non-metal roofs. In various embodiments, the roof vent adaptor includes a sealing member, an outer securing unit and an inner securing unit. The roof vent adaptor can be secured to the roof to provide a generally liquid-tight seal around the roof vent, thereby inhibiting or preventing water intrusion into the building.

A kit for flashing a mount of a photovoltaic assembly on a surface includes a flashing assembly. The flashing assembly includes flashing that extends across an interface of the mount and the surface when the mount is attached to the surface. The flashing includes a bottom surface and a top surface. The flashing assembly also includes tape attached to the bottom surface of the flashing. The tape includes a first attachment area and a second attachment area. The flashing assembly has a first configuration in which the first attachment area is attached to the flashing and the second attachment area is unattached, and a second configuration in which the first attachment area is attached to the flashing and the second attachment area is attached to the surface. The tape is movable with the flashing as an assembly when the flashing assembly is in the first configuration. The first attachment area and the second attachment area positioned on opposite sides of the tape such that the tape extends between the surface and the bottom surface of the flashing when the tape is in the second configuration. The kit also includes a container defining an interior space to receive the flashing assembly.

Implementations of a covered opening fastener are provided. In some implementations, the covered opening fastener comprises a shelf and a shaft or one or more spikes.

In some implementations, a method for using the covered opening fastener comprises attaching the covered opening fastener to an edge portion of a first object, such as a first roofing part, and driving the covered opening fastener into and/or through a second object, such as a second roofing part, to thereby attach the first object and the second object together by the covered opening fastener without forming an opening through the first object.
