The sheet of top wall flashing in a right pat tern are located on the top wall flashing as in a mirror.

The bracket has bend shape as the ending of its angular part, which joins with the flat part equipped with centrally located longitudinal through-hole.

Method of installation of roof flashing elements according to the present invention provides - by applying the fastening for joining of adjacent elements - simple fitting of them by slipping down of spe cifically formed ending of one element into specifically formed end ing of the other element, minimising mounting errors and maintaining continuity.

Possibility - due to horizontal and vertical mounting holes - of easy regulation and adjusting elements position on a roof construction results in that roof works performed on high and in tough conditions can be managed by one working man and guarantees quick (low la bour consumption) mounting of enduring, tight and aesthetic roof.

The use of factory-made mounting holes does not require drilling them through the surface of the roofing elements during in stallation - drilling causes the formation of filings that can damage roof membranes, corrosion of metal roofing elements and gutter sys tems.

The use of a lock system and factory-made mounting holes al lows for the disassembly and re-use of roofing elements without com promising their functionality and surface quality.

For eaves flashing and verge trims, after sliding the adjacent strips over each other, at the point of contact of the edge of the cut part of the longitudinal bend in the lock of one element and the edge of the longitudinal edge of the second element bend, a point of rotation of the elements relative to each other is created, limiting the possibility of other movements when screwing the assembly screws into the lon gitudinal mounting holes, especially in the holes of two overlapped eaves flashing or verge trims parts.

Before the adjacent eaves flashings and/or verge trims are slipped over each other, their side edges are pre-put on each other, which is possible due to the specific shape - a fastening and an intro ducing cut - and eliminates the need to precisely adjust the cooperat ing side edges of the strips when they are slipped over each other.

The elements of the roof flashing installation kit according to the invention, such as the verge trim, the eaves flashing, the bottom dry verge sheet, the external dry verge sheet, the valley gutter, the top wall flashing sheet, allow, thanks to the longitudinal bends (cooperat ing with the fastening), longitudinal edge bends, longitudinal double bends, longitudinal triple bends and longitudinal embossment main tain the stiffness of a single element and the stiffness, no so-called "undulating" of the entire roof treatment performed. The specific shape of the elements by longitudinal bends of the edge, longitudinal double bends and longitudinal embossments causes point contact of the element with a non-flat roof sub-construction, and thus the insens itivity of the finished roof treatment to mapping the roof sub-construc tion.

For the bottom dry verge sheets, the use of double coaxial mounting holes made in the longitudinal bend on the edge of the ver tical part, where the external hole has a diameter greater than the dia meter of the short head mounting screw and the internal hole has a diameter corresponding to the diameter of the short head mounting screw, when tightening the screws it is possible is to hide the screw head inside the longitudinal bend.

Additionally, for the bottom dry verge sheets and the external dry verge sheets, the use of mounting holes in special embossing (cups) allows for the installation of the head of the short head mount ing screw, so that when the edges of adjacent panels are slipped over, both the embossing and the low-headed screw heads placed in them are completely covered up.

Before sliding the adjacent sheets over each other, the side edge of one is initially put on the side edge of the other, which is possible due to the specific shape - fastening and introducinf cut - and elimin ates the need to precisely adjust the mating side edges of the sheets when sliding them over each other. Additionally, after placing the fastening in the entrance of the longitudinal bend with an introducing cut, it is possible to adjust the external dry verge in a limited range in the vertical direction.

The connection of the external dry verge sheet with the internal dry verge sheet is made in a way that prevents their separation other than protrusion - a longitudinal bend with a smaller bend angle of the external dry verge sheet is put on the longitudinal bend with a greater bend angle of the internal dry verge sheet as a snap and the edge of the longitudinal bend of the internal dry verge sheet it is blocked by the second bend of the longitudinal double bend of the external dry verge sheet.

For eaves flashings and verge trims, shifting the position of the mounting holes on the left side of the element in relation to the mount ing holes on the right side of the element by the material thickness of the element allows, after connecting adjacent elements by placing the beginning of the other element on the end of one element, such adjust ment of the mounting holes one above the other that their horizontal axis is maintained.

In roof flashing elements, such as a valley gutter sheet and an internal dry verge sheet, fastened with a bracket to the roof sub-con struction, the width of the bracket is smaller than the width of the hori zontal slotted holes and the longitudinal hole of the flat part of the bracket ensure easy adjustment and secure location of the roof flash ing elements on the roof sub-construction battens.

Positioning and adjustment with the use of the longitudinal hole of the flat part of the bracket applies to a single element during installation and after installation of the elements along the entire required length. It is enough to slightly unscrew the screws, correct the position of the element / elements and tighten the screws again. In this way, by ad justing the position of the internal dry verge, it is also possible to in directly adjust the position of the external dry verge, e.g. its straight ness in relation to the soffit. In addition, the specific shape of the bend of the bracket means that after placing the bend in the slotted hole, the bracket does not fall out by itself, although it is not yet fixed with a mounting screw through its longitudinal hole in the flat part to the roof sub-construction.

In the valley gutter sheets, the extension of one of their ends en ables easy insertion of the other, narrower end to obtain the required overlap, while maintaining the required contact of the surfaces of ad jacent sheets, and ensures proper sliding of the sheets relative to each other due to thermal expansion.

Kit of the roof flashing elements according to the invention enable the creation of a modular system consisting of short details that are easy to transport and logistics with the use of "EURO" pallets, which facilitates their universal availability for customers on an international and global scale.

Kit of the roof flashing elements according to the invention enable their correct shifting in relation to each other due to thermal expansion of the details.
