Molded roof flashing system

Abstract

A flashing strip for placement at an intersection between a wall and an adjacent roof against which a plurality of shingles are to be laid, the flashing strip comprising an elongated back panel from which a plurality of flashing tabs extend outward. The flashing tabs are disposed at an angle to the axis and in substantially parallel planes to one another. During use, the elongated back panel is disposed against and coupled to the wall at the intersection, and shingles are then placed along the flashing tabs during the roofing process. The flashing strip may also include a ledge and / or a decorative molding above the flashing tabs. The flashing strips may be placed end to end to form a continuous flashing strip that may be installed before the placement of siding or the like on the wall. The siding may be installed by positioning the siding against the ledge before or after placement of the shingles.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to roof flashing used in the installation and overlapping of roof shingles, and more particularly to a roof flashing system that includes molded lengths of roof flashing that are conveniently installed prior to the application of exterior wall coverings, yet permit installation of the shingles after the application of the wall covering. BACKGROUND OF THE INVENTION [0002] Leaks and damage resulting from water from rain or snow seeping into the cracks and crevices of a shingled roof have plagued many an unfortunate home or office dweller. The intersections of inclined roof slopes and upright walls or chimney structures are particularly problematic in that water tends to seep down along the upright wall or chimney structure, bypassing the roof, and finding its way along the rafters and interior ceilings. The damage resulting from such seepage may be severe, and often results in rotted wood or damaged plaster or plast...

Problems solved by technology

Leaks and damage resulting from water from rain or snow seeping into the cracks and crevices of a shingled roof have plagued many an unfortunate home or office dweller.

The intersections of inclined roof slopes and upright walls or chimney structures are particularly problematic in that water tends to seep down along the upright wall or chimney structure, bypassing the roof, and finding its way along the rafters and interior ceilings.

The damage resulting from such seepage may be severe, and often results in rotted wood or damaged plaster or plasterboard.

Repair costs of these elements of a structure are generally high.

Customarily, flashing is attached to the house one piece, or card, at a time as the roofer alternates between securing a flashing card to the roof and laying a shingle over the horizontal portion of the flashing card, a process which is very labor intensive.

Further, due to the cumbersome nature of the handling of the flashing cards and the shingles, it is generally difficult to achieve the desired security for the positioning of these elements in order to obtain the best seal possible.

Despite a roofer's great effort to provide an effective seal, water may still tend to seep in-between the flashing cards themselves and in-between the flashing cards and the shingles.

Primed lap siding, however, is relatively expensive, and rotting may result in the lower boards when placed directly against the shingles and flashing cards in the conventional manner.

In installing such siding, carpenters often estimate the clearance, or use a board as a spacer, methods which result in inconsistent results, at best.

While various methods have been proposed to simplify installation and enhance the sealing characteristics of the flashing cards and shingles, as well as siding, such attempts have been largely unsuccessful.

It has generally been considered is difficult to simplify the attachment of flashing material during a roofing project due to the variety of the thickness of shingles and the variety of types of materials used for shingles.

The strip, however, does not account for specific placement of the individual shingles.

As with Basset, however, the horizontal leg of Hunter is flat and continuous, and does not account for specific placement of individual shingles.
