Description

FIELD OF THE INVENTION

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

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.

Aluminum sheet metal flashing, or flashing cards having an “L-shaped” cross-section are typically installed at the intersections of the vertical and angled surfaces at the time the shingles are installed in an effort to minimize such seepage. The flashing is designed to manipulate the flow of water in a certain direction on the roof and to protect sections of a building where the shingles abut a wall or an edge. The horizontal (or angled) part of a flashing card rests on the surface of a roof along the joint between the roof and wall before the shingle is applied. The vertical portion of the flashing card may be nailed or attached via a tar-based adhesive to the upright surface against which it abuts.

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.

Wall treatment is typically applied to the vertical wall portion following installation of the shingles and flashing cards. Lap siding, for example, may be installed on exterior walls of a building. 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. As a result, some siding manufactures now require that a given space be maintained between the bottom of the siding boards and the surface of the roof shingle in order to maintain the siding warranties. 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.

In U.S. Pat. No. 5,946,862, Hoffman proposed the use of a plurality of individual flashing cards that are secured together in an overlapping fashion by stapling or gluing. The strip of coupled flashing cards is then secured to the roof by the roofer before applying the adjacent rows of shingles. Hoffman indicates that the amount by which the cards overlap is dictated by the width of shingles utilized, greater overlap for smaller shingles, and less overlap for larger shingles. Accordingly, the flashing cards must either be coupled together at the jobsite for the desired shingle size, or the roofer must maintain a large inventory of previously coupled cards that overlap by various amounts.

In U.S. Design Patent Des. 397,810, Basset proposes a continuous elongated L-shaped strip that is installed along the joint. The strip includes a relatively horizontal shoulder between the vertical leg and the horizontal leg of the strip for placement of siding other wall treatment. Shingles are laid along the horizontal leg in an overlapping fashion. The strip, however, does not account for specific placement of the individual shingles.

In U.S. Pat. No. 5,894,697, Hunter similarly provides a number of embodiments of a generally L-shaped flashing strip with a horizontal shoulder for placement of siding or the like. As with Basset, however, the horizontal leg of Hunter is flat and continuous, and does not account for specific placement of individual shingles.

An elongated flashing strip is provided which may be placed at an intersection between a wall and an adjacent roof as a substitute for traditional flashing cards. The flashing strip comprises an elongated back panel from which a plurality of flashing tabs extend outward. The flashing tabs are disposed at an angle to the elongated axis of the back panel, and are disposed in substantially parallel planes to one another. During use, the elongated back panel of one or more strips is positioned against and coupled to the wall at the intersection. The shingles are then placed along the flashing tabs during the roofing process. In this way, the roofer merely positions the shingles and nails them in place, eliminating the use of flashing cards altogether. As a result, the process of shingling a roof is much less time consuming, and more consistent and accurate. Additionally, the use of a unitary elongated flashing strip helps to minimize any potential seepage between flashing cards, shingles, the roof and the wall.

Preferably, the back panel of the flashing strip extends slightly below the flashing tabs. In this way, when installed at the intersection, the flashing tabs are canted slightly downward in order to direct drainage away from the intersection.

The flashing strips may be placed end to end to form a continuous flashing strip along a long intersection. Preferably, the leading and trailing edges of the flashing strips are overlapped slightly to provide a seep resistant environment. In this regard, the leading edge may be offset slightly in order to facilitate this overlapping and create a stop to position the strip.

The flashing strip may also include a ledge and/or a decorative molding above the flashing tabs. The siding may be installed by positioning the siding against the ledge before or after placement of the shingles. Thus, the ledge provides an easy and consistent means for ensuring uniform spacing of the siding from the surface of the roof or shingles. Further, the shingles may be installed after the placement of siding or the like on the wall, providing the builder substantial latitude in the use of subcontractors for the installation of both the roofing and the siding.

The flashing strip may also include a spacer disposed near either the leading or trailing edge of a flashing strip to maintain continuity and adequate spacing for shingles at the transition point between two adjacent flashing strips. In an arrangement where the leading edge comprises the spacer, when the trailing edge of a flashing strip is engaged with the leading edge of an adjacent flashing strip, the spacer makes contact with the flashing tab near the trailing edge of the adjacent flashing strip. Conversely, in an arrangement where the trailing edge of the flashing strip comprises the spacer, the spacer contacts the flashing tab near the leading edge of the adjacent flashing strip as the trailing edge of a flashing strip is engaged with the leading edge of the previously laid strip. The spacer ensures that adjacent flashing strips are vertically aligned and that there is adequate spacing between the flashing tab at the leading edge of one flashing strip and the flashing tab at the trailing edge of an adjacent flashing strip to accommodate a shingle disposed there between.

These and other features and advantages of the invention will be more readily apparent upon reading the following description of a preferred exemplified embodiment of the invention and upon reference to the accompanying drawings wherein:

DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning now to the drawings, there is shown in FIG. 1a, a schematic, perspective view of a fragment of a building wall 20 from which a dormer 22 extends. The wall 20 may also include strips of aluminum or wooden lap siding 21, as illustrated, or some other sort of protective or decorative treatment. The dormer 22 includes a roof 24 on which tarpaper 26 and then roofing shingles 28 are laid, and which meets the wall 20 at an intersection 30. A flashing strip 32 is provided along the intersection 30 of the wall and the dormer roof 22.

In accordance with teachings of the invention, and as shown in more detail in FIGS. 1b, 1c, 2a and 2b the flashing strip 32 is an elongated, molded structure that includes back panel 34 from which a plurality of flashing tabs 36 extend. The flashing tabs 36 are preferably rectangularly shaped and are spaced apart in a parallel, overlapping fashion at an angle to the top and bottom edges 38, 40 of the back panel 34, as may best be seen in FIGS. 1b, 2a and 2b. The flashing tabs 36 are preferably disposed at angle α on the order of 5° from an axis χ along the horizontal elongation of the flashing strip 32, as shown in FIG. 2a. In order to accommodate the shingles, the space between the flashing tabs 36 is uniform, and is equal to at least the thickness of the roofing shingle 28. Accordingly, the flashing tabs provide consistent placement and spacing of the shingles 28, as well as the flashing along a wall 20.

As may best be seen in FIGS. 1a and 3, in use, the back panel 34 is disposed against, and secured to the wall 20 with the flashing tabs 36 or the bottom edge 40 of the back panel 34 along the roof 24 or tarpaper 26. It will be appreciated that the flat back panel 34 and top edge 38 provide a smooth surface against which caulking my be readily laid, even if the strip 32 is disposed against a relatively uneven surface, such as a brick wall. To facilitate attachment of the back panel 34 to the wall 20, the back panel 34 may include preformed openings 42 through which a nail or screw 44 may inserted to couple the flashing strip 32 to the wall. Alternately, the carpenter or roofer may glue, staple, nail, or screw the flashing strip 32 to the wall 20, using the nail or screw 42 to pierce an opening in the back panel 34 if necessary. The roofing shingles 28 are then laid along and between the flashing tabs 36. Those skilled in the art will appreciate that the flashing strip 32 may be easily and quickly placed, and the shingles 28 conveniently positioned to form a substantially seep resistant intersection 30 between two adjacent angled surfaces 20, 24.

In order to further discourage liquid and other material from penetrating the space between wall 20, the roof 24, and the shingles 28, the bottom edge 40 of the back panel 34 preferably extends below the flashing tabs 36 (see reference 35), as may be most readily seen in FIGS. 2a and 2b. In this way, the flashing tabs 36 are raised slightly above the roofline to encourage drainage away from the intersection 30 and to allow for the placement of tarpaper 26.

To facilitate placement of the wall treatment such as siding 21, and to ensure that the siding 21 is disposed a consistent distance from the roof 24, the flashing strip 32 is preferably further provided with a continuous projection or ledge 46 which extends from the back panel 34. In this way, the strips of siding 21 may be easily and consistently positioned and secured to the wall 20 before or after installation of the roofing shingles 28. It will be appreciated by those of skill in the art that the ledge 46 is particularly useful when the ends of the strips of siding 21 are cut at an angle, as shown in FIG. 1a.

It will further be appreciated that the ledge may take an alternate form as shown, for example, in the embodiments illustrated in FIGS. 4a and b, and FIGS. 5a, b, c and d. For ease of explanation, the same numbers followed by lettered suffixes will designate similar elements of the alternate embodiments (e.g., the ledge in FIGS. 4a and b is identified as 46a, and in FIGS. 5a and b as 46b). In the embodiment shown in FIGS. 4a and b, the back panel 34a juts outward to form the ledge 46a, the back panel 34a extending below (35a) the flashing tabs 36a in a substantially parallel plane and extending back to the wall surface.

The back panel 34b of the embodiment in FIGS. 5a through 5d similarly juts outward to form the ledge 46b. This embodiment, however, provides a decorative molding or fascia 48 directly below the ledge 46b. The decorative molding 48 may be textured or colored to compliment the appearance of the exterior siding if so desired or to include other architectural features or colors. As may be most easily seen in FIG. 5b, the back panel 34b extends back inwardly 49 below the decorative molding 48, and then continues in substantially the same plane as the upper portion of the back panel 34b.

In other words, the back panel may include a number of portions extending in planes at angles to one another. For example, the back panel may include three portions extending in planes at angles to the adjacent plane, or five portions extending in planes at angles to the adjacent plane, as shown in FIGS. 4a-b and 5a-b, respectively.

In order to further inhibit seepage around the flashing strip and shingles, the flashing strip 32c may be provided with an offset portion 50 along the leading edge 52 of the back panel 34c, as shown in FIGS. 6a, 6b, 6c, and 7. In this way, the offset portion 50 of the leading edge 52 of a first flashing strip 32c may be disposed over the trailing edge 54 of an adjacent flashing strip 32d to form a continuous flashing strip assembly along an intersection between the two surfaces of the wall and the roof. Thus, the offset portion 50 must be offset at least enough to accommodate the thickness of the trailing edge 54.

It will be appreciated that the offset may be in the form of the back panel 34c angling outward from the major plane of the back panel 34c, as shown in FIGS. 6a-7, or the offset portion may be in the form of a reduced thickness portion of the back panel 34c, so long as the offset is sufficient to accommodate the trailing edge, which may likewise be of a reduced thickness. Alternately, depending upon the geometry, the trailing edge 54 may include an inwardly offset portion. The embodiment illustrated in FIGS. 5a-5d includes both an outwardly offset 50b leading edge 52b, and an inwardly offset section 51b at the trailing edge 54b. As may be best seen in FIG. 5d, the ledge 46b, molded facia 48, and inwardly extending portion 49 are offset inwardly at 51b approximately the thickness of the strip 32b in these areas.

It has been determined that a leading edge on the order of one and one-half inches is sufficient to provide engagement and adequate sealing between two adjacent strips. According to an important aspect of this embodiment, the leading edge 52, 52b, 52c of the flashing strip 32b, 32c or 32e is disposed downhill along a ramped surface of a roof to inhibit water from seeping around the strip 32b, 32c or 32e.

To permit the leading edge 52, 52b, 52e and trailing edge 54, 54b of adjacent flashing strips 32b, 32c, 32d to accommodate one another, the offset portion 50, 50b, 50e of the first flashing strip 32b, 32c, 32d is notched out below the leading flashing tab 36e, as shown in FIG. 6a. Further, the ledge 46d at the trailing edge 54 of the second flashing strip 32d is notched out, as shown in FIG. 7 or the protruding facia 48 reduced in size as shown in FIGS. 5c-5d. In this way, the leading 52 and trailing edges 54 may be engaged to provide a continuous ledge or facia and series of flashing tabs as shown in FIGS. 5d and 7. It will be appreciated, however, that the trailing edge 54 need not be so notched if the flashing strip 32e is not provided with a ledge, as illustrated in FIGS. 8a and b.

According to another aspect of the invention, the flashing strips may comprise structure to facilitate accurate registration from one strip to the next. In certain applications, a user may inadvertently place adjacent flashing strips 32b, 32c, 32e slightly askew or not leave sufficient room for a shingle to fit between flashing tabs 36 on adjacent flashing strips 32b, 32c, 32e. In order to maintain continuity and adequate spacing for shingles at the transition point between two adjacent flashing strips 32b, 32c, 32e, the flashing strips 32b, 32c, 32e may have a structure for spacing a flashing tab 36 of a flashing strip 32b, 32c, 32e a certain distance above a flashing tab 36 for an adjacent flashing strip 32b, 32c, 32e. In accordance with the teachings of the invention, a flashing strip 32b, 32c, 32e may have a spacer 60 of any appropriate design disposed at any appropriate position that provides proper positioning as subsequent strips 32b, 32c, 32e are placed.

In the embodiments shown in FIGS. 9a-13b, the spacer 60 extends downward from the flashing tab 36 or the offset portion 50 at the leading edge 52, and preferably lies in substantially the same plane as the offset portion 50. The bottom edge 62 of the spacer 60 is preferably angled relative to the bottom of the flashing strip 32b, 32c, 32e at approximately the same angle α as the flashing tabs 36. The vertical distance that the spacer 60 extends downward from the flashing tab 36 at any given point along its length is preferably approximately the same distance as is between two flashing tabs 36 on a single flashing strip 32b, 32c, 32e, thus maintaining the substantially parallel relationship between flashing tabs 36. The spacer 60 may extend the length of the offset portion 50 as shown in FIGS. 9a, 9c, 9d, 10a, and 11a. Alternately, the spacer 60 may extend only a portion of the length of the offset portion 50 as shown in FIGS. 12a and 13a. It will be appreciated, however, that the spacer 60 may be of any appropriate shape and the bottom edge 62 of the spacer 60 may have an alternate shape so long as the spacer is disposed such that it defines the desired spacing between flashing tabs. Further, the designs illustrated in FIGS. 9a-13b are provided by way of example, and not limitation.

It will be appreciated by those of skill in the art that the spacer 60 may alternately be disposed at the trailing edge 54 of the flashing strip 32b, 32c, 32e, as shown in FIGS. 14a and 14b. In this arrangement, the spacer 60 extends upward from the flashing tab 36 near the trailing edge 54 of the flashing strip 32b, 32c, 32e to make contact with the underside of a flashing tab 36 near the leading edge 52 of an adjacently disposed flashing strip 32b, 32c, 32e. One of ordinary skill in the art would appreciate that the spacer 60 may have any suitable length and/or shape. The spacer 60 may be a separate piece that is attached to the flashing strip 32b, 32c, 32e or it may be molded as part of the flashing strip 32b, 32c, 32e.

By way of example and not limitation, as shown in FIG. 9d, when the leading edge 52 of a flashing strip 32b, 32c, 32e is engaged with the trailing edge 54 of an adjacent flashing strip 32b, 32c, 32e, the spacer 60 makes contact with the flashing tab 36 at the trailing edge 54 of the adjacent flashing strip 32b, 32c, 32e. The spacer 60 ensures that adjacent flashing strips 32b, 32c, 32e are vertically aligned and that there is adequate spacing between the flashing tab 36 at the leading edge 52 of one flashing strip 32b, 32c, 32e and the flashing tab 36 at the trailing edge 54 of an adjacent flashing strip 32b, 32c, 32e to accommodate a shingle disposed there between.

According to another important aspect of the invention a flashing strip constructed according to teachings of the invention is preferably molded of a flexible material, such as an elastomeric or a thermoplastic material, preferably a polypropylene copolymer, such as is used in outdoor lighting fixtures. If surfaces of the flashing strip are exposed to the elements, the material should be resistant to degradation due to weather and sunlight. As a result, the individual strips are relatively low in weight, economical to manufacture, and yet have excellent resistance to the elements. The strip may also be molded in different colors, particularly if it is visible when installed.

In summary, the invention provides a plastic molded, continuous roof flashing system which eliminates the need for the placement of individual flashing cards during the roofing process. The back panel of a strip having a plurality of flashing tabs may be quickly and accurately placed against a wall at its intersection with a roof. The back panel may be secured to the wall by any appropriate mechanism, such as glue, nails, or otherwise, and caulked or otherwise sealed as necessary. The flashing strip may further include a ledge against which a wall treatment, such as siding, may be easily and accurately placed.
