The pocket 206 is provided by a flat Z-shaped portion of the second leg, whereby the flat Z-shaped portion has a cross-section with a flat Z-shape.

The second said lateral longitudinal flashing elements 300 likewise has a generally L-shaped cross-section with a first leg 301 and a second leg 302. The first leg 301 is adapted to be arranged against a side of a respective one of the roof elements 400 raising from a plane of the roof 410 in a mounted position, and the second leg 302 is arranged to extend along said plane of the roof 410 in the mounted position. The first leg 301 and the second leg 302 are joined at a corner 303 of the L-shape, and an inner side 301a of the first leg and an inner side 302a the second leg relative to the L-shape constitutes a concave side of the lateral longitudinal flashing element 300. A distal edge portion 304 of the second leg opposite the corner is bent towards the concave side at an angle α3 to form an apex 314, and the second leg 302 comprising a slit-shaped pocket 305 with an opening towards the distal edge portion and a bottom 306 towards the corner 303 of the L-shape. The pocket 306 is provided by a flat Z-shaped portion of the second leg, whereby the flat Z-shaped portion has a cross-section with a flat Z-shape.

In the embodiment shown the second leg 202, 302 of the first lateral longitudinal flashing element 200, and the second lateral longitudinal flashing element 300, respectively has a width W between the corner 203, 303 and the apex 214, 314, and the pocket 105, 205, 305 of the second leg 102, 202, 302 of respectively the lateral intermediate flashing element 100, the first lateral longitudinal flashing element 200, and the second lateral longitudinal flashing element 300, has a depth d1; d2; d3 that is equal to or larger than 50% of the width W11; W2; W3 of the lower longitudinal end 121 of the lateral intermediate flashing element 100; the first lateral longitudinal flashing element 200; and the second lateral longitudinal flashing element 300.

In the embodiment shown the angles α1, α2, α3 forming the apexes 114, 214, 314 are acute angles.

In the embodiment shown the opening of the slit-shaped pocket 105, 205, 305 of respectively the lateral intermediate flashing element 100, the first lateral longitudinal flashing element 200, and the second lateral longitudinal flashing element 300 is provided at a respective first bend portion 108, 208, 308, and the bottom 106, 206, 306 of the respective slit-shaped pocket 105, 205, 305 is provided by a respective second bend portion 109209, 309, and in a mounted position, cf. FIGS. 2 and 3, a longitudinal part of the second bend portion 209 of the first lateral longitudinal flashing element 200 is accommodated in the slit-shaped pocket 105 of the lateral intermediate flashing element 100 at its upper longitudinal end 120, and a longitudinal part of the second bend portion 109 of the lateral intermediate flashing element 100 at its lower longitudinal end 121 is accommodated in the slit-shaped pocket 305 of the second lateral longitudinal flashing element 300.

Referring to FIGS. 6 and 7, it is noted that the respective sizes or widths of the respective pockets 105, 205, and 305 in a vertical direction as seen in the figures should be sufficient to receive the respective intended bend portions and further the pockets thus joint should have open widths sufficient to receive a sheet-formed element, as explained below.

It is further noted that due to the Z-shape, apart from the pockets 105, 205, and 305 opening on the inner sides 102a, 202a, 302a of the second legs 102, 202, 302, respectively, second pockets parallel to the first pockets 105, 205, and 305 are opening at the respective second bend portions 109, 209, and 309. Some of these second pockets will also accommodate bend portions as it will be envisaged by the skilled person, but e.g. the second pocket of second lateral longitudinal flashing element 300 will not receive a bend portion and may be collapsed as seen in FIG. 7.

It should be noted that e.g. the longitudinal portion 110 of the lateral intermediate flashing element 100 may be provided as a single bent piece of sheet material or it may be provided e.g. from more bent pieces of sheet material that are connected e.g. by a joint 132.

Referring to the drawing of the second lateral longitudinal flashing element 300 in FIG. 7 it is noted, for the sake of clarity, that the part indicated by reference numeral 310 is a hooked portion at a distal end of the second lateral longitudinal flashing element 300.

In the embodiment shown the depths d1; d2; d3 of the pockets 105, 205, and 305 opening on the inner sides 102a, 202a, 302a of the second legs 102, 202, 302, respectively are substantially equal. The widths W2 and W3 of the first and second lateral longitudinal flashing elements 200 and 300 are substantially equal, whereas the width W12 of the lower longitudinal end 121 of the lateral intermediate flashing element 100 is smaller than the width W3 of the second lateral longitudinal flashing element 300, and width W11 of the upper longitudinal end 120 of the lateral intermediate flashing element 100 is larger than the width W2 of the first lateral longitudinal flashing element 200.

For flashing a roof element e.g. a roof window, the lateral intermediate flashing element, the first lateral longitudinal flashing elements 200, and the second lateral longitudinal flashing elements 300 may be assembled by

• • inserting in a longitudinal direction A the lower end 121 of the lateral intermediate flashing element 100 into an upper longitudinal end 320 of the second lateral longitudinal flashing element 300 for a longitudinal part of the second bend portion 109 of the lateral intermediate flashing element 100 at its lower longitudinal end 121 to be accommodated in the slit-shaped pocket 305 of the second lateral longitudinal flashing element 300, and
  • inserting in the longitudinal direction A a lower longitudinal end 221 of the first lateral longitudinal flashing element 200 into the upper longitudinal end 120 of the lateral intermediate flashing element 100 for a longitudinal part of the second bend portion 209 of the first lateral longitudinal flashing element 200 to be accommodated in the slit-shaped pocket 105 of the lateral intermediate flashing element 100 at its upper longitudinal end 120.

FIG. 1 illustrates roof windows mounted at different altitudes along a slanted roof. In the example shown, windows are mounted in horizontal side-by-side relation in a lower row 401 and above the lower row 401 an upper row 402 of windows are mounted, thus at a higher altitude along the slanted roof.

Whereas FIG. 1 indicates that the roof is covered with tiles and the present invention is intended for the flashing to cooperate with sheet material, such as metal sheet material, line VIII-VIII in FIG. 1 indicates the general position of a section to provide a view as shown in FIG. 8.

FIG. 8 illustrates how the flashing according to the present invention may cooperate with a second longitudinal element e.g. as taught by EP 3 480 388 A1 from which FIG. 8 is replicated.

FIG. 8 partially shows part of the window 400 namely a main frame side element 420, a sash element 421, and a pane 422. Further FIG. 8 shows the second lateral longitudinal flashing element 300′ in a variant having a slightly deeper pocket 305′ than shown in FIG. 7. The shown lateral longitudinal flashing element 300′ is mounted with its first leg 301′ arranged against an external side of the main frame side element 420. The second leg 302′ of the lateral longitudinal flashing element 300′ is extending along the plane 423 of the roof. Further, the main frame side element 420 and the sash element 421 are respectively provided with cladding elements 420a, 421a.

Next to the window 400 a carrier profile 424 is provided for carrying e.g. a solar panel (not shown).

In order to provide for covering the roof between the window 400 and the carrier profile 424 a second longitudinal element 425 is provided. The second longitudinal element 425 is a sheet element with a first side portion 426 accommodated in the pocket 305′ of the lateral longitudinal flashing element 300′, and with a second side comprising a bent edge portion 427. A gasket 428 provides for completing coverage of the roof between the second longitudinal element 425 and the carrier profile 424.

The present invention provides for a combined slit-shaped pocket 105, 205, 305 to extend all along roof windows, or other roof elements, mounted next to each other at different altitude, as shown in FIG. 1, whereby the combined slit-shaped pocket may receive e.g. a second longitudinal element like the second longitudinal element 425 extending all along the combined length of the roof windows or roof elements.

As an alternative to a second longitudinal element like the second longitudinal element 425 the combined slit-shaped pocket 105, 205, 305 may receive sheet covering for a roof as taught in the above-mentioned WO 95/28535 A1.
