STATEMENT REGARDING FEDERALLY-SPONSORED RESEARCH OR DEVELOPMENTNot Applicable
BACKGROUND OF THE INVENTION1. Field of Invention
The present invention relates generally to roof flashings for establishing a weather-proof seal with pipes.
2. Description of the Related Art
Roof flashings are used to create a substantially weather-proof and moisture-proof seal around pipes extending through roofs and other exterior walls of houses and other buildings. Such pipes are used, for example, as vent stacks (hereinafter, “vent pipes”) for venting interior plumbing to the atmosphere.
Roof flashings of this type often comprise two components: a base member that sits substantially under the tiles of the roof and against the roof, anchoring the flashing; and a seal or gasket (hereinafter “gasket”) to form a weather-proof seal around a pipe that extends through the flashing. Often, due to exposure to the elements and due to the fact that the gasket is fabricated from different and less durable materials than the base member, the gasket will become corroded or porous and require replacement much earlier than the base member. However, because the base member and the gasket are integrally connected, the whole flashing unit must be replaced. The replacement process involves removing tiles from the roof in order to gain access to the base member and replacing the entire flashing unit.
BRIEF SUMMARY OF THE INVENTIONThe present invention, in some of its various embodiments, comprises a flashing with a base member for placing against a roof, a lower stack member connected to the base member, and an upper stack member with a gasket for forming a tight seal with a pipe, the upper stack member being detachably connected to the lower stack member. Because the upper stack member with the gasket is detachably connected to the lower stack member, when the gasket is so degraded that it should be replaced, the upper stack member with gasket are removed without removing or replacing the base member and lower stack member of the flashing.
In one example embodiment, a flashing according to the present general inventive concept includes a base member, a lower stack member, and a detachable upper stack member. In some embodiments, the upper stack member includes a gasket for forming a weather-proof seal around a vent pipe. In some embodiments, the lower stack member includes threads onto which the upper stack member is screwed. In some embodiments, the upper stack member is detachably connected to the lower stack member by pressure fitting. In some embodiments, the lower stack member includes a lip that interacts with a complimentary lip on the upper stack member; the lip on the lower stack member connects with the lip on the upper stack member in a snug or close frictional fit. In several embodiments, the lip of the upper stack member, or the whole upper stack member itself, is fabricated from an elastic material that is capable of being non-deformably stretched; the upper stack member is detached from the lower stack member by stretching the lip of the upper stack member in order to decouple it from the lip of the lower stack member.
Generally, an example embodiment of the present invention comprises a roof flashing with a detachable component for forming a seal with a pipe, the roof flashing comprising a base member for placing against a roof, a lower stack member connected to said base member, and an upper stack member with a gasket for forming a tight seal with a pipe, the upper stack member being detachably connected to the lower stack member. In some embodiments, the roof flashing includes an upper stack member that is connected to the lower stack member by screwing the upper stack member onto threads on the lower stack member. In some embodiments, the roof flashing includes an upper stack member that is connected to the lower stack member by pressure fitting. In some embodiments, the roof flashing includes a gasket that comprises a rubber material. In some embodiments, the roof flashing includes a gasket that comprises a mixture of rubber and plastic.
A flashing with a detachable upper stack member, according the present general inventive concept, provides a weather-proof seal around a pipe that extends through the flashing. When the upper stack member (or a component of the upper stack member, such as a gasket in some embodiments) becomes corroded or porous and requires replacements, replacement of the detachable upper stack member does not involve replacing the whole flashing or removing tiles from the roof in order to gain access to the base member.
The above-mentioned and additional features of the invention will become more clearly understood from the following detailed description of the invention read together with the drawings in which:
The present invention, in some of its embodiments, includes a flashing with a base member, a lower stack member, and an upper stack member detachably connected to the lower stack member. In some of the various embodiments, a roof flashing with a detachable component to form a seal with a pipe comprises a base member to place against a roof; a lower stack member connected to said base member; and an upper stack member to form a tight seal with a pipe, said upper stack member being detachably connected to said lower stack member.

In some embodiments of the present general inventive concept, a flashing with an upper stack member detachably connected to the lower stack member, such as the illustrated example embodiment flashing 12 shown in
In various embodiments, the components of a flashing according to the present general inventive concept are fabricated from a variety of materials. In some embodiments, the lower stack member is fabricated from aluminum. In some embodiments, the lower stack member is fabricated from poly-vinyl chloride. In some embodiments, the lower stack member is fabricated from a plastic material. In some embodiments, the lower stack member is fabricated from a material including polyethylene. In some embodiments, the lower stack member is fabricated from a polymeric olefin. In some embodiments, the lower stack member is fabricated from copper. In some embodiments, the upper stack member is fabricated from rubber. In some embodiments, the upper stack member is fabricated from poly-vinyl chloride. In some embodiments, the upper stack member is fabricated from a plastic material. In some embodiments, the upper stack member is fabricated from a polymer material. In some embodiments, the upper stack member is fabricated from a combination of rubber and other materials.

A flashing with a detachable upper stack member, according to one of the several embodiments of the present general inventive concept, provides a weather-proof seal around a pipe that extends through the flashing. When, due to exposure to the elements or other factors, the upper stack member (or a component of the upper stack member, such as a gasket in some embodiments) becomes corroded or porous and requires replacement, a user is able to replace the upper stack member without replacing the base member. Thus, replacement of the detachable upper stack member does not involve removing tiles from the roof in order to gain access to the base member or replacing the entire flashing unit.
