The technology for arranging the roof provides not only the installation of rafters, as well as the laying of covering material, but also the filing of the cornice. To do this, a wooden lining, metal or vinyl siding, as well as a planed board, are installed on the eaves of the gables and eaves. However, today on sale you can find a more modern and new material called soffit for roofing.
The need for work
If you want to build a house that will last more than one decade, then the roof should extend from the surface of the walls by 50-70 centimeters, which will protect materials from the effects of rainfall. In this case, in the roofing cavity, it is necessary to form an overhang, which is covered with roofing material from above, and hemmed from below. This allows you to give the house an aesthetic and finished look, as well as solve the issue of arranging ventilation of the under-roof space.
If you want to use the soffit for filing the roof, then it must be installed with a gap of 15 millimeters. This will provide traction for the airflow that will come from the lower edge of the overhang. Thus, air circulation and ventilation of the space with the elimination of moisture are ensured. If ventilation is intense, then the life of the roof will last, but fungus and mold will not appear.
Spotlight Description
Spotlights for roofing have the form of panels that are designed for horizontal surfaces facing down during operation. In fact, this material is the same lining or siding, but with a special structure that allows air to pass through and does not interfere with its circulation. The presence of perforation acts as the main difference between spotlights, which are usually used in the open air.
Spotlights for roofing are fixed to the box along the perimeter of the roof. The panels will dock with each other using a lock connection, which allows you to hide the fasteners.
Dimensions
The length of spotlights can be equal to the limit from 3 to 3.6 m. As for the width, its range varies from 22 to 30.5 cm. The dimensions of the material will depend on the manufacturer. For example, Canadian and American companies produce a triple profile with a width of 30 centimeters, while the length is 3.6 linear meters. These parameters are the most optimal for roofing.
Spotlights selection
Before you will be hemmed the roof of the house, you need to choose a variety of spotlights, which can be solid, perforated or with partial perforation in the center. The first type of material is great for covering the ceiling of an open veranda, garden gazebo or porch. Using these paintings, you can provide constant access to the inner surfaces of the roof, this will allow air to rid the interior of moisture.
If the roof is covered with non-profiled material, then it is better to use perforated soffits, which are indispensable in the decoration of the protruding parts of the roof like cornices, peaks, overhangs, pediments and skates. If it is necessary to provide ventilation in the under-roof space, it is best to use canvases with perforation in the center. With the help of them on the overhang of the eaves it will be possible to create a unique composition with alternating one continuous strip of perforation with two stripes.
Preparatory work
Before the roof of the house will be hemmed, it is necessary to warm the walls from the outside. The key to a successful binder is the correct measurements, so first you need to make a drawing that will help you navigate the sequence of actions. Thus, initially it is necessary to determine the technology, which may include filing along the rafters or creating a horizontal box from the edge of the rafters to the wall.
In the first case, it will be necessary to choose an angle that coincides with the angle of the ramp. This technique is used for roofs that have a slight slope. The spotlights are installed on the rafters parallel to the plane of the walls. In the case when the lower plane of the rafters is not even, it should be leveled, for which trim boards are screwed to the rafters, the thickness of which should be 4 centimeters. It is necessary to use screws for this. Initially, the first and last boards are installed, between which it is necessary to pull the rope and fasten the remaining elements. In the place where the ramps converged, boards should be strengthened from all sides.
Horizontal binder
This technology is indispensable when the roof has a steep slope. At the same time, installation work can be carried out quite quickly, and the material is significantly saved. To work from the bars, a box is built, which is fixed to the rafters and the wall from above and from below. When water enters the overhang, it will drain, and the beam located on the rafters should be placed below the wall beam by a centimeter.
If there is an overhang of more than 45 centimeters in the middle, you will need another longitudinal beam. The remaining elements are reinforced with bars that are perpendicular to the wall.
Roofing
Sewing the roof with soffit is carried out on the crate. In order to fix the details to it, self-tapping screws with a washer should be used . For the installation of the first strip, you should determine the starting point of location, deviating from it 77 centimeters. After that, a horizontal line is beaten around the entire perimeter of the house. An initial strip is set beneath it to make corner elements and equip the edging. Next, you should mount the internal and external elements of spotlights.
If you are thinking about how to hem the roof, you need to make sure that the lower end is closer to the surface of the earth with respect to the edge of the initial strip. Corner elements are strengthened with self-tapping screws installed in the groove, steel fasteners should be in their middle part. Apertures should be surrounded by platbands or edging.
Specialist recommendations
When the cornice is hemmed, the parts are joined at an angle of 90 degrees. Panels should be installed starting from the original strip. Before mounting the last panel, you must install the final strip. The wall panel is cut to the required dimensions, in the last strip the cut end is clamped.
In order for the installation to be of high quality, you should also use nails, they are clogged from the central part of the panel towards the edges. In this case, it is necessary to exclude the formation of gaps. If there is a need to cut the panels, then you can use a circular saw, and for small workpieces, metal scissors are perfect.
Price and variety of spotlights
Soffit metal is the most resistant to environmental influences. These paintings have a huge selection of colors. Among other things, quite often they come complete with a roof. This is because they are made of polymers together with metal. These products outperform their competitors. However, the most popular among consumers are aluminum spotlights, which are distinguished by practicality, moderate cost and high adaptability. Easy installation is ensured by low weight, which allows hemming even tall buildings.
Copper spotlights are distinguished by auto-attenuation of corrosion and resistance to aggressive environments. The spotlights of copper spotlights are not visible, since they are closed by the connection. Sheets without perforation can be used even indoors, but perforated spotlights are perfect for horizontal space on the street.
You should be prepared for the fact that copper elements in the air quickly become coated with an oxide film, which gives the product a yellowish red tint. During operation, the color slowly turns brown, and after the base is covered with a patina and acquires a malachite-green hue. If you consider yourself a connoisseur of antiquity, then it is worth choosing just such spotlights.
Copper spotlights for roofs, the price of which is 2390 rubles per piece, can be perforated or solid. You can install them yourself, while the roof can last more than 150 years, without suggesting the need for painting or care. In addition to the cornice sheathing, it will be necessary to purchase accessories. These include the frontal bar, the cost of which is 1300 rubles apiece. Its size is 20x145 millimeters, while the length is equivalent to 2000 millimeters. You will need a groove in the work, which costs 650 rubles. Its length is 3000 millimeters.
