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.

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.

The present invention is a reliable and simple to install device for protecting of passages for utilities in roof structures from the entry of adverse effect outdoor weather elements. The device is composed of: a flexible tube component (FTC), a surface insertion tube component (SITC), a surface connection plate component (SCPC) and a SCPC-connecting paste component. FTC is composed of a hallow semi-flexible tube having one side unconnected and the other side firmly connected to the SITC, forming a continues tube. The SITC is composed of a rigid hallow tube divided into two portions by the SCPC. The SCPS is composed of a perforated, rigid material, perpendicularly fixated to and around the SITC, In installing the device of the present invention, the SCPC-connecting paste component is smeared on the external surface of a roof structure surrounding the passage for utilities. The unconnected side of SITC is inserted into the passage for utilities till the SCPC is tightly pressed into the SCPC-connecting paste component. The SCP is pressed until the SCPC-connecting paste component oozes through the perforated plate of the SCPC. Upon drying and hardening of the SCPS connecting paste component, the SCPS is fixated and the device is stabilized. After the device is fixed and stabilized the FTC is stretched and bent in an approximately 180 degree angle so as to have the unconnected opening of the FTC approximately aligned in parallel with, and facing the external surface of, a roof structure surrounding of the passage for utilities. Either after the bending of FTC or prior to starting the installation of the device, utilities can be inserted through the FTC and SCPS.

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.

Disclosed are sealing apparatuses used in conjunction with corrugated roofing around chimneys, vents, solar tubes, and other structures protruding through corrugated roof or siding. In one embodiment a specialized gasket comprising gasket ribs having a profile that matches a chosen corrugated sheet metal barrier is utilized. A transition barrier hole is cut into the corrugated sheet metal barrier and then the hole is used to cut a transition gasket hole in the gasket. A sealant is used between the gasket and mating parts to create a seal about the transition vessel to prevent roof leaks. In some embodiments, the gasket is in the form of gasket plugs which may be trimmed and utilized to plug and seal the corrugations surrounding a transition barrier hole in a corrugated sheet metal barrier.

A roof pipe flashing with a rectangular shaped side air attic vent attached to a partial boot with a frusto-conical wall and a flat base for exhausting air from an attic into the outer atmosphere during warm or hot seasons in order to help reduce the internal house temperature during these seasons.

A roof flashing having a base and a flexible collar operatively connected thereto is configured to prevent water infiltration around an exhaust pipe extending through a roof. The base includes a flat plate having a connecting mechanism extending upwardly from the plate. The collar includes either a fixed-diameter opening or a multi-diameter opening thereto, wherein the opening is configured to receive and seal against a pipe extending from the roof to which the roof flashing is attached. The collar is fixedly attached to the connecting mechanism of the base.

A roof flashing is disclosed herein. The roof flashing can include a bottom half having a first plate and a first neck portion and also a top half having a second plate and a second neck portion. At least one of the first neck portion and the second neck portion can include a pipe portion formed from a first material and a sealing portion formed from a second material. The sealing portion can define one of the first portion of the aperture and the second portion of the aperture. The first material can be more rigid than the second material. The sealing portion can define a top surface facing upwardly and a bottom surface facing downwardly and a plurality of beads projecting outwardly from the top surface and a plurality of channels extending inwardly into the bottom surface.

A roof curb is used in association with a roof flashing installed on a roof with an incline and corrugated ribs, the roof flashing having a base member that may be mounted over a substantially vertical chimney in the roof and a hollow member having a first end and a second end, the first end being larger than the second end and the first end being attached to the base member of the roof flashing. The roof curb includes a first skid and a second skid that may be mounted upon the roof substantially in a direction of the incline and substantially parallel to each other. The first skid and the second skid each have a length that terminates in a top end and a bottom end, each of the first skid and the second skid being tapered such that the bottom end of each of the first and the second skids has a height greater than the top end, the first and the second skids being selectively attached to the roof to bridge the corrugated ribs and the taper being of a gradation to permit attachment of the roof flashing to the roof curb and passage of the substantially vertical chimney therethrough, the roof curb being discrete from the roof flashing.
