ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to roof flashing and, more specifically, to an elastomeric skylight membrane formed as a single piece having a planar membrane element having a centrally positioned membrane collar element enclosing an aperture. The skylight membrane is inserted over the framed rough opening for a skylight having the membrane collar element tightly engaging the framing members and of substantially the same height as the rough opening framing members. The planar membrane element engages the roof sheathing and is fixedly attached thereto by any means well known within the art. In addition, a turnback edge is exteriorly positioned on the up slope side of the membrane collar element for the purpose of preventing water from wicking between the skylight frame and the skylight membrane. This is especially necessary as the slope of the roof increases.
The water which encounters the turnback side of the collar has a tendency to flow tangently. To prevent this water from traveling across the shingles, the planar membrane element has two spaced apart ridges transversely positioned to the turnback collar side. The diverter ridges spaced away from the turnback side impedes transverse water flow returning it to a downward flow.
Furthermore, positioned along three sides of the periphery of the planar membrane element is a bead that will redirect any water that has accumulated between the skylight membrane and shingles to a downward flow.

A roof flashing and method of making same in which both the collar and base member of the flashing are made of elastomeric material. The base member is molded first and has an opening therein surrounded by a stepped flange provided with a series of circumferential slots therein. The collar is molded onto the base member during a subsequent molding operation in which the material of the collar is injected through the slots and completely around the top, bottom and inner side edge of the flange to form a series of closed loops thus providing a positive mechanical lock between the collar and base member. Also, the heat of the elastomeric material of the collar during the second stage molding process causes some melting of the elastomeric material of the base member whereby the collar and base are also fused together.

A one piece flexible elastomer boot membrane flashing of EPDM extends from the roof upwardly around the wood base frame and over the top edge to provide a complete seal for a skylight window unit. A tape seals the outer edges of the outwardly extending peripheral lower flange portion of the boot to the roof. The skylight may be either of the fixed or ventilator type.

A weatherseal flashing is made from sheet vulcanized rubber and surrounds a sklight frame situate on a roof curb. The weatherseal consists of a plurality of sealedly lapping panels each embodying a relatively wide apron and an upstanding flange extending along one elongated edge of the rectangular-shaped panel. The ends of each panel flange have overlapping sealedly connected wings on their ends to provide collectively, a continuous fastener for surrounding the inner side or leg of the skylight assembly to make a co-planar seal in engagement with the combined projecting curb and the skylight frame, and the roof surface.

A flashing including an elastomeric collar with an inner surface and an outer surface and adapted to seal against more than one size of a vent pipe passing vertically through a central opening in the collar. The elastomeric collar has a circular base adapted for interconnection with a base member and a central opening including, a first annular ring defined by a first separation circle and a second separation circle, at least one additional annular ring outwardly therefrom that is frangibly separable from the first annular ring at the second separation circle and frangibly separable from the elastomeric collar at a third separation circle. Each annular ring selectively is removable by a pull tab that extends vertically from the outer surface of each annular ring at a location proximate to the separation circle of that ring with respect to the elastomeric collar.

An improved device for forming a weather-tight seal to a vent pipe and over a roof flashing. The device utilizes a high durability elastomeric material with a truncated conical shape and thickened upper lip to form a rain shed over the roof flashing, thereby ensuring a tight, durable seal to the vent pipe that prevents intrusion of moisture between the vent pipe and roof flashing.

Structural support members are surrounded with a cover that insulates the outer envelope of the support member. The cover may be made of an elastomeric material sufficiently flexible to permit the cover to be physically installed about the structural member. The structural member and cover may also be provided with interlocking means that will retain the cover on the support member once it is installed. Disclosed is a skylight framework formed of a plurality of spaced rafters joined by a plurality of crossbars wherein the rafters and crossbars each include an elongated central support member having a cover member that surrounds the outer envelope of the elongated support member except for a central fastener opening.

An improved two-piece roof flashing comprises a thermoplastic hard base and an elastomeric rain collar. The hard base comprises a planar base plate with a central dome like portion, with the dome-like portion having a central opening with a solid flange inwardly disposed and encircling the opening. The rain collar has a central opening sized to accommodate an upstanding roof pipe. The rain collar is molded directly onto the solid flange of the hard base, with the resulting seam between the rain collar and hard base being strong and weathertight. When the collar is molded onto the flange of the base element, the mater
