Calculation and arrangement of the counterparts and crate for metal tiles

Here at "All about the Roof," we explore the fundamentals of roofing to empower you to make wise choices for your house. Today, we’ll concentrate on the measurements and placement of roof decking and battens for metal tiles—two essential procedures for guaranteeing a sturdy and well-built roof.

The placement of battens and roof decking, also known as the roof’s counter battens and crate, is crucial when installing metal tiles. These elements offer support and guarantee appropriate water drainage, laying the groundwork for the installation of the metal tiles. To ensure structural integrity and longevity, careful measurements and considerations must be made when calculating these components.

Installed perpendicular to the roof rafters, counter battens are usually composed of metal or treated wood. Their main function is to allow air to pass between the roof decking and the metal tiles. This opening permits ventilation, which lessens the risk of temperature fluctuations and moisture buildup beneath the tiles, protecting the roof structure from possible harm.

The local building codes and the roof pitch are two of the factors that determine how the counter battens should be arranged. To evenly distribute the weight of the metal tiles and to account for potential thermal expansion and contraction brought on by variations in the weather, the batten spacing must be sufficient. To guarantee the roof’s performance and stability over time, these computations are crucial.

Direct attachment of the metal tiles to the substrate is accomplished by means of roof decking, also known as the roof crate. It supports the weight of the roofing material and gives the tiles a stable foundation. While there are many options for deck materials, plywood and oriented strand board (OSB) are frequently utilized because of their resilience to different weather conditions and strength.

The span between rafters, the anticipated load from snow or wind, and the particular requirements of the selected metal tile system are some of the factors that must be taken into account when calculating the required thickness and strength of the roof decking. Maintaining the structural integrity of the roof and avoiding problems like sagging or premature wear of the roofing material require careful installation of the decking and adequate support of the tiles.

In addition to ensuring a well-executed installation, knowing the basics of counter battens and roof decking for metal tile roofing also helps to prolong the lifespan and durability of your roof. Homeowners can improve their roofing system’s functional dependability and aesthetic appeal by attending to these important details during the planning and construction stages.

Why do you need a crate

Roof crate: a straightforward design with numerous indications of a tiny cross section that is positioned perpendicular to the rafters. A frame like that serves multiple purposes:

• load distribution from the roof pie. On each square meter of roof, taking into account the load from snow, more than 300 kg of weight affects. In this case, an important point is its uniform distribution, which avoids deformation of the roof;
• Giving the form of slopes. The crate is the basis for the subsequent laying of roofing material and determines the geometry of the entire roof;
• Fixing roofing. With the correct choice of a step of the crate, the roofing material can be evenly fixed with fixed elements, thus ensuring resistance to large wind loads.

"To ensure durability and efficiency when installing metal tiles on a roof, it is essential to calculate and arrange the counterparts and crate carefully. This procedure includes building a sturdy framework (crate) that endures weather and efficiently supports the tiles, as well as figuring out the proper arrangement and spacing of the battens (counterparts) that support the tiles. Gaining an understanding of these calculations and configurations facilitates the construction of a sturdy roofing system that improves both structural integrity and aesthetic appeal."

The device for metal tiles

The secret to high-quality roof material laying is proper metal tile crate arrangement. As a result, it is worthwhile to pause and consider certain details at key points, such as the calculation and installation of the crate, the material selection, and the spacing between the structural elements.

Choosing material and type of structure

Typically, metal tiles made of pine, spruce, or fir are used as the material. Use deciduous rocks if you can’t get coniferous ones. Pine is the best material because it is reasonably priced, has good strength, hardness, and processing suppleness. It is important to keep in mind that the wood needs to dry completely before being placed on the roof; additionally, there shouldn’t be any rotted areas or evidence of insect activity. The thickness of the wooden components should also be uniform. Over time, a board or beam will skew if it is not enough or is not dried properly (lead).

Apart from selecting the materials, you should be aware that different kinds of crates are constructed beneath metal tiles:

1. Substitite. This is the most common option. It is used on different roofs with a slope of more than 20 °. In this case, the distance between the centers of the boards is equal to the wavelength of the tile.
2. Continuous crate is used for structures with an angle of 14–20 °. Despite the fact that the frame is called continuous, it is not recommended to mount the boards to each other, since the material has the ability to expand. To compensate thermal deformations, a gap of 2-3 cm is left.
3. Combined. Combined type of crate combines both previous options. The sparse is used over the entire surface of the roof, except for nodes such as yendovs, the adjoining of the roof to the wall or pipe. In these areas, a continuous frame is mounted. In addition, the continuous base is equipped:
4. around the attic windows, roofing hatches, in places of external and internal fractures of the roof slopes;
5. at the place of attachment of roof safety elements (snow retainers, roofing, bridges and stairs);
6. In the top of the roof, where two boards are additionally installed at a distance of 2-3 cm for a reliable fastening of the metal strap of the ridge.

The minimum angle of inclination for a metal tile roof is 14 °.

How to choose a step between rows

The size of the pillow materials used as chatter for metal tiles can vary:

• For installation of conventional structures, 25×100 mm boards are used;
• Under the material with the base from thick galvanizing, boards are used 32×100 mm;
• If the roof design has a large step between the rafter legs, a beam with a cross section of 40×60 mm or 50×50 mm is selected for the crate.

Since the materials should be able to support people carrying a load during installation, it is unacceptable to use an unspeakable or half-sovereign board.

The kind of tile and its specifications determine the stage of the rarefied crate. For the roofing material in question, 35 cm is the standard value. You can fix the coating at the lowest wavelength with this size. The manufacturer of the roofing material typically provides the relevant information. In the absence of recommendations, the coating’s wavelength is used to calculate the separation between the boards. For profiled tiles, the standard frame sizes are 30, 35, and 40 cm. The crate’s step for the Metallic Tiles "Monterrey" is 35 cm.

Necessary tools

You must get ready the following set of tools in order to construct the frame:

• roulette;
• level;
• triangular ruler;
• felt -tip pen;
• screwdriver;
• hammer;
• galvanized nails and screws;
• tools for cutting wood (electrolobian, electronics, hacksaw);
• staircase.

Calculation and sizes of the crate for metal tiles

In order to avoid fasteners in the void during wrapping screws, it is necessary to properly place the labels. In this case, it is important to calculate the distance between the rows. It is best to use the existing roofing for calculations or know its exact dimensions. Parameters of sheets, as well as the additional elements of metal tiles, are different – from 0.4 to 8 m in length and 1.16–1.19 m in width. This suggests that the installation of the crate without knowledge of the size of the metal tile can lead to errors in the calculations. As a result, it may be necessary to redo the entire frame. The size of the crate for the tile is not difficult to calculate. The procedure is reduced to determining the wave step and the corresponding arrangement of boards or bars.

Installation sequence

Once everything is ready, you can begin the installation process. Considering that Monterrey metal roofing is characterized by a broad color palette and can be installed on structures with a variety of architectural styles, take into consideration the placement of the crate beneath the tiles. Installation is carried out in the order listed below:

1. Along the cornice, two boards are nailed with a section of the boards 50×100 mm on each other.
2. Waterproofing material is removed over the starting boards.
3. On the bars of the counter -pitch equal to the pitch of the wave of roofing material (350 mm), the labels of 25×100 or 32×100 mm are horizontally stuffed horizontally. A special template is used to monitor the step of the crate.
4. On the skate, a crate on the side of each slope is stuffed on the skate.
5. In Endov, a crate of a continuous type is installed.
6. On the end side of the rafters, the board is nailed and the end strips are fixed to it, carrying out the laying of the one by 7-10 cm.
7. Hooks are attached to the cornice for the drainage system, after which the cornice of the bar is installed.

Features of the crate on the gable roof

For a basic roof with two slopes, the crate and counter are made with the same steps—30 cm on each side. When installing boards and bars in more intricate configurations where the internal corner joints form, care must be taken to ensure that the installation follows the manufacturer’s specifications and the roof’s geometry in a step-by-step manner between rows. The four-sked roof’s frame is constructed in a similar manner.

Flip in the field

Endova is the inner angle of the roofing system. This site experiences much larger loads than the rest of the roof area, since water flows through it, in winter it withstands a large snow mass, and in the summer it heats up more in the sun. So that there are no leaks in this place, it is necessary to approach the device of the valleys with special responsibility. An additional layer of waterproofing material is laid on the inner angle. The counter is nailed with a step of not more than 10 cm, while the beam should not be attached to the flooring of the Endovs, since this will negatively affect the ventilation and removal of condensate.

Compared to the remaining roof area, the inner angle of the roof’s crate is constructed with a half-step less.

Metal tank

The appointment of a metallic metallic metallice is essentially limited to the subcutaneous space’s opening for air to pass through. There is open space for air because the structure is attached over waterproofing.

Do you need a metal tank

The following are the counterparts’ advantages:

• roof ventilation is provided;
• The formation of mold and fungus on the elements of the rafter structure is excluded;
• The decay of wooden elements of the roof is prevented;
• Condensate does not accumulate on the back of the roofing material.

It follows that installing the metallic metallic installation is required. In addition to the benefits already mentioned, the design enables us to address the irregularities that were permitted during the rafter system’s construction.

The thickness of the counterbrus

Basically, a beam measuring 135–137 cm in length and 30×50 mm in cross section is used to install the counter. Such lumber is sufficient to construct a basic roof. A broken roof requires a larger cross section—50 by 50 mm—when it is constructed. Along a single rafter leg, the spacing between the counterpart’s elements shouldn’t be more than 30 cm.

Installation instructions

Once the bars are ready to be installed, you can move on to the installation process, which is done in the following order:

1. Wooden elements are processed with special means that prevent rotor of the tree and its defeat with insects.
2. After laying the waterproofing, the counter is fixed using galvanized nails.
3. In the process of stuffing, ensure that the bars are parallel to each other and perpendicular to the cornice bar.
4. On the frame, the counter -crate is marked.
5. Tags are interconnected with a coloring cord.
6. Mount the crate, putting the desired thickness, if necessary.

For metal roofing to be both long-lasting and effective, it is essential to know how to measure and set up the battens and framework. To support the weight of the tiles and ensure proper ventilation, the process entails precise measurements and considerations.

First, determining the dimensions and spacing between the battens requires determining the particular needs of the metal tiles that are being used. Usually, variables like the roof slope, local weather, and tile profile determine how far apart battens should be spaced. In addition to providing support for the tiles, this spacing allows for appropriate ventilation and drainage, lowering the possibility of moisture buildup and subsequent damage.

Second, the overall stability and lifespan of the roofing structure are greatly influenced by the placement of the battens on the roof. In order to ensure even weight distribution and prevent sagging over time, the battens are typically installed perpendicular to the roof slope. Furthermore, the way the battens are oriented affects how well rainwater runs off the roof, avoiding pools that can jeopardize the structural integrity of the roof.

Last but not least, building the crate or framework that holds up the battens needs careful attention to detail and compliance with regional building codes. Usually constructed of metal or treated wood, the framework offers a sturdy foundation for fastening the metal tiles and battens. When the framework is installed correctly, the entire roofing system is kept safe and resilient against weather-related stresses like wind, rain, and snow.

In summary, a successful roofing project requires an understanding of the calculation and placement of battens and framework for metal tiles. Homeowners and contractors can guarantee a roof that not only improves a building’s visual appeal but also offers dependable protection and long-term durability against the elements by being aware of these fundamentals.
