The operation of the roof primarily implies the possibility of access to it. There are several channels through which the approach to the upper level of the building is possible, among which the internal one, for example, through the attic. But not always using this path is convenient. In some cases, the necessary repair and construction tasks help to solve special roofing stairs. Roofs with such equipment are subject to lower maintenance loads and do not pose a danger to the user himself.
Roof Features
The main distinguishing feature of such stairs is the installation configuration, in which the user gets the opportunity to move around the ramp. In this case, the slope acts only as a supporting part, on which mounting racks are fixed . Depending on the characteristics, the roofing ladder may also include the function of an autonomous shifted bridge. So, if in the first case a constant fixation of the device is provided, then the staircases are fixed temporarily. The features of this option include the ability to install the structure only on slopes that are suitable for dimensional parameters.
It is important to note another difference between the roofing models of stairs. As a rule, these are devices with a minimum weight and high strength characteristics. Especially these qualities are important if the roofing ladder is used on the roof with an unstable and sensitive coating.
Varieties
The group of roofing stairs includes several varieties. First of all, these are structures that are mounted directly on the slopes. But in order to get to the very level of the roof, an appropriate device is also required. And this function is already performed by the facade roof staircase, which is installed on the wall and forms a path from the ground or balcony to the upper part of the house. At the same time, it is not worth considering constructions of this type only as external ones. Another variety can be called attic models. Such a staircase also connects the attic or attic with access to the pitched surface. According to building regulations, without fail the infrastructural support of the house must include an emergency staircase. This applies to buildings in which the windows of residential premises are at a height of more than 3.5 m.
Material classification
As noted above, the requirements for roofing ladders can be attributed to stringent requirements in terms of compatibility of strength and light weight. This requirement makes manufacturers more thoroughly approach the selection of materials. For example, the most reliable is the steel version of the stairs, but it differs in considerable weight. If you need a roofing ladder for a metal tile with a rigid base, then this option is quite suitable. But the characteristics of the protective coating should be taken into account - it must necessarily prevent corrosion processes.
An alternative is aluminum. Due to its low weight, this design can be used on fragile roofing, but it is important to keep in mind the low strength characteristics of the soft metal staircase itself. The least common are wooden structures, but they are also the most affordable. This option is best used as a lane-type bridge.
Installation of stairs
At the first stage of the project, a technical plan is developed. Design parameters, the number of modules, acceptable and optimal mounting methods, etc. are determined. Special fasteners are included in the set of factory metal stairs of this type. In particular, it can be roofing and ridge brackets, due to which installation is realized. And in the installation, it’s rather important not to prepare the stairs themselves, but to create the basis for fastening in the roof niche. It is advisable to use the fixing nodes not in the coating itself, but in the beams and frames of the truss structure. That is, installation should be through the coating. In addition to fixing hardware, a rigid seal is also used, due to which the roof ladder itself adds to the reliability. It’s quite easy to carry out installation operations with your own hands - especially if there is a drill screwdriver at hand. This device will allow you to make the necessary holes in the beams and fasten the staircase at the fixation points.
Price issue
The cost of stairs is determined by many parameters. Among them, one can distinguish sizes, and material of manufacture, and the composition of the configuration. So, an aluminum model 1.8 m long with a basic set of clamps can cost 1.5-2 thousand rubles. Steel structures rarely cost less than 2 thousand. If we talk about complex systems that include several modules in the kit, then the cost can increase to 4-5 thousand. The most attractive option in terms of performance is a galvanized roof staircase. The price of models with such a coating starts from 3 thousand and then rises to 10 thousand, if we talk about the segment of household products.
Conclusion
Perhaps the most important issue that should be resolved in the course of equipping a house with a roofing roof is ensuring reliability and safety. Moreover, the matter concerns not only safety for the user, but also the absence of negative factors for covering the roof. The presence of a metal structure often causes the destruction of the decorative material. This may be due to the fact that the roofing ladder was improperly fixed, as a result of which moisture began to spread along the connection nodes. Accordingly, such processes do not promise anything good either to the staircase or to the roofing base. There are also dangers of a different nature, when an incorrect calculation of the mass was originally made. Even if at the first time of operation the heavy structure does not give signs of a dangerous effect on the roofing material, then in months or years, deformation will certainly appear.
