When performing roofing, in addition to the basic materials for coating and insulation from water and heat loss, so-called additional elements are also needed . These include details such as the endova, ridge, end plate and others. These elements protect the inner layers of the roof from external environmental influences, therefore, it is necessary to correctly select and install these devices.
End strip: description and specifications
This device has two functions:
- protective - the device removes moisture from the edge of the overhang from the gable side of the roof and prevents rain from splashing in the oblique direction;
- decorative - the fixture gives the finished look to the coating of the structure, it allows you to hide irregularities and roughness in the work.
The end plate, as a rule, is made of steel or metal using special processing technology (galvanizing at high temperatures) coated with high-quality polymer. Such an element is characterized by good technical characteristics, such as resistance to destruction under the influence of solar radiation, when the temperature drops, the constant presence of moisture, and so on. Polymer coating can be performed in various colors (white, red, green, yellow and others).
The shape of the device can be made as simple (part shelves are symmetrical), and figured (provides for an additional bend). The length of the product can be taken equal to the following values - 2 m, 2.5 m and 3 m. Shelf sizes as standard: 9 × 9 cm or 9 × 12.5 cm.
Mounting the part on a roof with a coating of corrugated board
The end plate, as a rule, is installed before the main work is performed (laying of roofing material). When installing this part, it will be useful to take into account such points:
- the installation of the bar is carried out above the crate at a distance equal to the height of the wave of deflection of the corrugated sheet;
- the additional element can be attached to wooden parts using screws or self-tapping screws, while the connection must be made from the side to the end plate and from the top to the roofing material (in the wave crest);
- installation of the device is recommended to start from the edge of the overhang of the roof towards the ridge (where the excess part of the part needs to be cut);
- the end plate for corrugated board is attached with a small overlap (about 10 cm);
- about 60 cm are taken as a step for connecting parts on the basis of the roof.
Mounting fixtures on a metal tile
An additional element is installed in almost the same way. It is important to consider the following points:
- all measurements must be carried out accurately;
- when installing the bar should cover approximately the height of the crest of the first wave of tiles;
- if the edge of the roofing sheet does not coincide with the level of the cornice, the coating material must be cut off (with excess) or continued (with shortage);
- the part is attached to the roof in two places - maximum points and on the end board, which is installed in advance;
- the connection can be made with screws, self-tapping screws or countersunk rivets, while the step can be 60-100 cm.
The end plate for the roof allows you to strengthen the roof structure, while hiding and protecting the internal elements. This device increases the service life of the coating, as it does not allow moisture and solar radiation to get on the wood parts. The use of this additional element also gives completeness to the exterior decoration of the structure.
