Lateral intermediate flashing element for connecting lateral longitudinal flashing elements, a kit comprising such flashing elements, and a method of flashing two roof elements positioned adjacent each other at different altitudes along a slanted roof

A method of flashing two roof elements positioned adjacent each other at different altitudes along a slanted roof, said method comprising:

• providing a kit of flashing elements comprising a lateral intermediate flashing element comprising
• a longitudinal portion having a generally L-shaped cross-section with a first leg and a second leg, the first leg being adapted to be arranged partly against respective sides of the roof elements, the second leg being arranged to extend along said plane of the roof in the mounted position, the first leg and the second leg being joined at a corner of the L-shape, an inner side of the first leg and an inner side of the second leg relative to the L-shape constituting a first side of the longitudinal portion, a distal edge portion of the second leg opposite the corner being bent towards the first side at an angle to form an apex, and said second leg comprising a slit-shaped pocket with an opening on the inner side towards the distal edge portion and a bottom towards the corner of the L-shape, said pocket being provided by a flat Z-shaped portion of the second leg, said flat Z-shaped portion having a cross-section with a flat Z-shape,
• the longitudinal portion having an upper longitudinal end and a lower longitudinal end, a width of the longitudinal portion between the corner of the L-shape of the longitudinal portion and the apex being smaller at the lower longitudinal end than such width of the longitudinal portion at the upper longitudinal end;
• a first lateral longitudinal flashing element having a generally L-shaped cross-section with a first leg and a second leg, the first leg being adapted to be arranged against a side of a respective one of the roof elements raising from a plane of the roof in a mounted position, the second leg being arranged to extend along said plane of the roof in the mounted position, the first leg and the second leg being joined at a corner of the L-shape, an inner side of the first leg and an inner side of the second leg relative to the L-shape constituting a first side of the lateral longitudinal flashing element, a distal edge portion of the second leg opposite the corner being bent towards the first side at an angle to form an apex, and said second leg comprising a slit-shaped pocket with an opening towards the distal edge portion and a bottom towards the corner of the L-shape, said pocket being provided by a flat Z-shaped portion of the second leg, said flat Z-shaped portion having a cross-section with a flat Z-shape;
• and
• a second lateral longitudinal flashing element having a generally L-shaped cross-section with a first leg and a second leg, the first leg being adapted to be arranged against a side of a respective one of the roof elements raising from a plane of the roof in a mounted position, the second leg being arranged to extend along said plane of the roof in the mounted position, the first leg and the second leg being joined at a corner of the L-shape, an inner side of the first leg and an inner side of the second leg relative to the L-shape constituting a first side of the lateral longitudinal flashing element, a distal edge portion of the second leg opposite the corner being bent towards the first side at an angle to form an apex, and said second leg comprising a slit-shaped pocket with an opening towards the distal edge portion and a bottom towards the corner of the L-shape, said pocket being provided by a flat Z-shaped portion of the second leg, said flat Z-shaped portion having a cross-section with a flat Z-shape,
• wherein the opening of the slit-shaped pocket of respectively the lateral intermediate flashing element, the first lateral longitudinal flashing element, and the second lateral longitudinal flashing element is provided at a respective first bend portion, and the bottom of the respective slit-shaped pocket is provided by a respective second bend portion, and in a mounted position,
• a longitudinal part of the second bend portion of the first lateral longitudinal flashing element is accommodated in the slit-shaped pocket of the lateral intermediate flashing element at its upper longitudinal end, and
• a longitudinal part of the second bend portion of the lateral intermediate flashing element at its lower longitudinal end is accommodated in the slit-shaped pocket of the second lateral longitudinal flashing element;
• inserting in a longitudinal direction the lower end of the lateral intermediate flashing element into an upper longitudinal end of the second lateral longitudinal flashing element for a longitudinal part of the second bend portion of the lateral intermediate flashing element at its lower longitudinal end to be accommodated in the slit-shaped pocket of the second lateral longitudinal flashing element;
• and
• inserting in the longitudinal direction a lower longitudinal end of the first lateral longitudinal flashing element into the upper longitudinal end of the lateral intermediate flashing element for a longitudinal part of the second bend portion of the first lateral longitudinal flashing element to be accommodated in the slit-shaped pocket of the lateral intermediate flashing element at its upper longitudinal end.
