The ridge is a very important element of the roof. Robust and flawless execution of the ridge is of great importance in terms of aesthetics of the entire roofing, but also the durability and tightness of the roof.
In order to properly finish the ridge (as well as the so-called hail ridge, hail tiles) a number of conditions must be met. Ventilation openings must not be omitted, especially in the case of long roof pitches. Ventilation tiles suitably located on the slope, as well as properly made eaves with ventilation comb, enable efficient air circulation under the slope, which translates into long life of wood (battens, counterbattens). The last rows of battens (so called roof battens) must be installed at a sufficient distance from each other in order for the ridge to cover the ridge correctly.
Directly related to the function, as well as the installation of ridge ridge, are actually all the work that we have to do on the roof in the first place. The shaping of the gables starts in principle already at the stage of laying the underlay (membranes) Different solutions should be applied to the top of the roof depending on the type of underlay. If full boarding covered with roofing paper is required, a gap in the boarding should be left in the gable and the roofing paper should be cut along the gable to allow air circulation and water vapour removal. With highly vapour-permeable membranes, the roof gable is tightly placed on both sides through the ridge, so as to create at least 20 cm overlap.
The next step that affects the correct installation of ridge is correct latching and patch straightening . When doing this, the greatest attention should be paid to the last, highest rows of patches. The distance of the batten from the apex point of the slope is determined on the basis of the dimension LAF. It depends on the angle of inclination of the slope and the type of covering. The ridge batten (on which ridge tiles are mounted) should be fixed according to the dimension FLA. Manufacturers practically always state these dimensions in the technical sheets of their products. It is essential to observe and use these provisions.

Another important activity is the installation of ridge patch brackets. There are two basic types of them: superimposed and hammered in. The choice of these elements depends on the roofing and construction, the knocked in brackets are driven into rafters throughout the whole sheathing and are fixed with stainless steel screws. The spacing of handles should be about 60 cm if the structure of the rafter framing allows it. Usually, in the case of driven-in brackets, these distances will be greater, as the average rafter spacing on roofs ranges from 60 to 90 cm. The brackets should also be set at the appropriate height in one line so that the ridge train is not curved and wavy. Then attach the ridge battens to them using stainless steel screws.
The next stage is the installation of ridge ventilation elements. We can now choose from long known ridge brushes as well as more and more popular and frequently used ridge tape.
Using brushes is a simple operation, where we focus on tight connection of bristle elements with each other, with the use of tape we have to remember that the surface of tiles is clean, because its installation consists in sticking the edges of the tape to the tiles. The tape is equipped on the edges with adhesive strips based on butyl glue. The tape should also be skillfully profiled at the corners of the tile so that it adheres tightly along its entire length. Also, it is not recommended to install the tape at an ambient temperature lower than 5 degrees Celsius.
The last and main activity is the desired assembly of ridge ridge. We start this activity by attaching the so-called starting ridge. Depending on the product, it can be specially profiled, and it can also be a basic ridge to which are attached respectively start and end caps, usually mounted on screws. After assembling the starting ridge, we move on to screwing the basic ridge. At the end of the ridge we mount a closing ridge. In some models it is also profiled, ready, and in some brands are used for basic ridge ridge special ends. Special clamps are used between ridge paddles by which one ridge is screwed on and the next ridge is held with it and screwed back at the other end with the use of a clamp, etc. The ridge paddles are also used for the ridge paddles.

*Initial cover.
The ridge endings not only provide an aesthetic finish, but also protect the roof against snow and rainwater from the gable sides of the building.
There are also situations when, due to the shape of the building, two (or more) ridges merge in one point. In order to cover such places, manufacturers produce special fittings in different angles, including ridge triceps.
*Three-armed ridge, most often used at the connection of the main ridge with the sloping ridge.
On the roofs where 3 ridge tiles meet in the 90° account, a T-piece of T-type is mounted. There are also fittings for connecting 4 ridge tiles found in multi-pitched roofs where the hailstones meet at a single point.
Regardless of the type of work, let's remember to make every effort to properly perform all the installations. The manufacturer's card with recommendations will be very helpful. Even if someone likes challenges and manual work in the open air, I recommend hiring a professionalist for complex tasks.
