Not all structural elements of the house necessarily require additional design in order to give aesthetic appeal. The roofing maintenance system, depending on the technical implementation, can do without decorative finishes. However, the presence of pronounced overhangs of the structure makes roofers pay special attention to the refinement of these elements. In this way, the roof is hemmed, which has not only a decorative, but also a power function in the form of providing additional reliability.
What is a roof overhang and its filing?
In one form or another, this design solution is implemented in almost all modern houses with ramps. In essence, this is the part of the slope that protrudes beyond the plane of the walls. Another thing is that each building has an overhang of a certain size, as well as an individual finish. Usually there are wide and narrow overhangs. The elongated parts of the roof slopes look more solid - especially as part of private suburban buildings surrounded by green spaces. A narrow cornice overhang also has its advantages, including the possibility of compact development in a small area. In addition, a short slope makes the building more slender andelegant.
This is not to say that an overhang is a must for a modern home. You can do without it by completing the roof slope at the point of convergence with the wall line. However, the deprivation of a strong support makes the roof less strong and durable. Such solutions are used only by experienced and highly qualified architects who are able to accurately calculate the proportions of the roof and the building. But most often, the project of the roof of the house assumes the presence of overhangs that protrude beyond the plane of the walls, the design of which can be done in different ways.
Required tool
To choose tools and consumables should be after a rough plan for arranging the overhang has been drawn up. So, if a metal building material for finishing is involved in the work, it can be a set of professional locksmith tools. If it is supposed to use a perforated soffit, then you can limit yourself to the basic carpenter kit. The standard list of tools includes the preparation of a drill, a screwdriver, a hammer, a hacksaw, measuring instruments and a stepladder. Again, depending on the roof construction materials, heavier equipment such as an angle grinder may be needed.
As for consumables, the basis of this set is hardware suitable for fixing the material used in the arrangement of overhangs. In particular, roof filing can be done with nails, screws, self-tapping screws and even staples. Special compositions may also be required to protect surfaces: metal requires anti-corrosion treatment, andwood - application of moisture-resistant coatings.
Bundling techniques
Overhangs can be hemmed parallel or perpendicular to the slope. Usually, sheathing is used in the form of panels and laths, so this classification is appropriate in most cases. The only exception is the use of whole metal sheets - in this case, the configuration of the location of the cladding does not matter. So, the simplest option involves installation parallel to the rafters, which will form a common plane at the lower ends. This is the optimal roof filing with an angle within 30 degrees. In this case, the extension length is usually about 50 cm. Installation is carried out along a crate made of boards and fixed to the rafters. As technology requires, the elements are parallel to the wall.
If the roof has a steep slope, it is better to install perpendicular to the rafters. First of all, a box is formed from the bars, which is subsequently attached to the wall and to the rafters, that is, at two points. To ensure effective drainage, it is necessary to lower the beam located on the rafters 2 cm lower relative to its wall-mounted counterpart. As reinforcement, you can use additional mounting bars. These are the main options for filing the roof, but in some cases it makes sense to use alternative methods for decorating this part of the roof. So, to increase the decorative effect, a diagonal layout of the planks is sometimes used. But in this case, reliability may suffer.designs.
What materials are used in the work?
Perhaps, this is one of the main issues, the solution of which determines the success of the entire event. Among the most popular materials used in this operation, it is worth highlighting the soffit, which forms the lower part of the eaves. The advantages of this solution include the fact that the design itself, the dimensions and the overall appearance of the material optimally matches the operational tasks of the slope. In particular, a cornice overhang with such a design organically complements the classical architectural compositions of country houses. The rest of the surface of the protruding part is finished with clapboard, plywood or siding. Actually, there are no special differences in the types of these materials as such, since in each group you can find a suitable solution for a particular overhang.
No less important are the stylistic qualities of the finish. First of all, you should think about the color scheme. Pastel colors make the space under the roof lighter, and dark shades that are difficult to perceive, on the contrary, plunge the eaves into shadow. At the same time, it is not necessary for the roof lining to correspond in texture to the roofing. This is the case when a contrasting combination of colors is allowed in different parts of the building. However, in choosing a shade, one cannot do without taking into account the natural qualities of the material itself. Of course, the natural texture of wood will look the most advantageous, but original paintwork can also be provided for it. And now it is worth considering separately the options for finishing with different materials.
Filing the roof with siding
It should be noted right away that siding can be metal, wood and plastic. It is for this purpose that a finish based on polyvinyl chloride (PVC) is preferable, since it is not afraid of moisture and is easy to install. Siding panel kits usually also include fastener kits - these are connecting elements, corners, groove clamps, as well as U-shaped components for trimming edges. Accordingly, the filing of the roof is carried out depending on the method of fixation provided by the manufacturer of the siding elements. Most often, installation is carried out perpendicular to the walls. Fixation is provided at several points, the number of which increases as the width of the overhang increases. The only thing that experienced roofers do not recommend doing in such a finish is the installation of planks along the slope. This scheme is more suitable for wooden lining, which has a higher mechanical resistance.
Soffit for roof filing
Like siding, spotlights are equipped with special mounting kits, the use of which increases the ease of installation and its quality. Planks are usually supplied with J-profiles, designed to bring several elements together into one skin. Soffits themselves are panels made from different materials. For example, vinyl spotlights, as already noted, are distinguished by decorative properties, as well as resistance to external influences. The small mass of this variety does not overload the structure, but at the same timetime preserves the power function.
For massive roofs with wide overhangs, it is recommended to use aluminum and copper counterparts. Light metals also do not pose a danger in terms of overload, but at the same time provide sufficient strength to the slope. The highest safety effect is provided by perforated soffit, specially designed for installation as part of a cornice. Thanks to the presence of grooves in the panels, even an inexperienced builder can easily form a strong and reliable roofing sheet.
Sheathing with corrugated board
From the point of view of ensuring the reliability of the overhang, this is a good choice, but in terms of installation and decorative properties, everything is not so smooth. As for the nuances of installation, fixing is carried out in any position of the sheet on the prepared crate. The complexity of the procedure may cause the need for initial refinement of the corrugated board in accordance with the dimensions of the working surface, therefore it is recommended to purchase sheets of the desired format in advance. The decorative properties of metal cladding are very modest - as much as possible the surface can be painted, but even in this case the effect will be far from the same siding. Also, vinyl spotlights without special treatment look much more spectacular and presentable. During the installation of sheets, it is necessary to leave gaps for ventilation. Since we are talking about a continuous metal coating, the inclusion of special gratings for the formation of ventilation channels is a prerequisite for installation. It is also necessary to think over the possibilities of future integration of deviceslighting. If other finishing materials are easy to refine, then with metal such operations are more difficult to perform - again, the best option would be a professional surface correction prior to installation to fit the size of the lamp.
Finishing the overhang with clapboard
Both lining and chipboard panels can be a good option for overhang sheathing, but only if their surface is treated with high quality. In fact, due to the presence of a factory protective coating, such a finish is preferable to the use of traditional boards. That is, you should purchase either a moisture-resistant lining, or chipboard panels with a similar layer. Installation is carried out on a prepared crate. Its presence provides for the overhang of the roof, since the fixing of the planks to the adjacent section of the wall can be carried out directly to the facade. During installation, do not be afraid of the formation of large gaps - in the future they can serve as ventilation holes, which will benefit the under-roof space. If the work is carried out in a house with an attic, then it is better to equip the ventilation with special gratings, and perform the filing with minimal gaps.
Cost of work
In terms of price, the filing operation corresponds to the work on laying the main roofing or facade cladding. It is not recommended to save on such a design, since it is not only about a decorative function. So, the cost of roofing work on thisplot averages 400-600 rubles/m2. If the activities are carried out as part of the overall installation of the roof, then the prices may be lower. On the other hand, the technical complexity of the organization of the workflow can increase the cost of operations.
Of course, in the general calculation of the cost of finishing, the price of the material used is also inevitable. The most expensive will be a soffit, which can be purchased for 300-400 rubles/m2. Siding with high-quality lining is also not cheap - about 200 rubles / m2. If it is planned to design overhangs at minimal cost, then it makes sense to choose an unsightly, but practical metal corrugated board. In this case, the total cost of roofing work will be approximately 700-800 rubles/m2, together with the payment for the services of the roofer. An ordinary board is also cheap, but this option should only be used if there are preparations for moisture-proof treatment, since it is not recommended to perform sheathing from wood in its pure form.
Conclusion
The overhangs protruding beyond the plane of the outer walls visually underestimate the house. In addition, the wide extension of the slope causes the formation of a horizontal division of the volume of the building. If you introduce horizontal support components into the design, this perception will be enhanced. It also makes sense to calculate the decorative possibilities of a narrow overhang. For small houses, which are located on modest plots, this solution justifies itself due to the visual sensation of the compactness of the building. Specific parameters for the removal of the roof should containthe project of the roof of the house, which also reflects the graphical configuration of the location of the overhang relative to the walls. At the stage of developing a technical solution, the possibilities of using materials with certain qualities are calculated. It is important not only to evaluate their mechanical and stylistic features, but also their compatibility with other elements of the roof structure. In some cases, for example, experts recommend supplementing the finish with insulators, which along the edges of the roof form a reliable protection of the attic from moisture.
