Planning and installation of roofing materials require a thorough understanding of the weight of schifer sheets. Schifer sheets are a popular choice for roofing because of their weather resistance and durability. They are also referred to as 7 and 8 wave sheets. These sheets are constructed from a range of materials, including composites and metal, and are intended to endure the weather for extended periods of time.
Schifer sheets come in different weights based on their thickness and material makeup. Because of its thinner profile, a 7 wave sheet typically weighs less than an 8 wave sheet. When it comes to structural considerations during building and renovation projects, this weight differential is significant.
An 8 wave sheet of the same material might weigh somewhat more, about Y kilograms per square meter, than a standard 7 wave schifer sheet made of metal, which might weigh about X kilograms per square meter. These weight variations may not seem like much, but they can have an impact on the cost of transportation, the simplicity of installation, and the roof’s overall ability to support weight.
If you intend to use Schifer sheets for roofing, you should speak with suppliers or roofing experts to figure out what weight and material will work best for your particular project. While choosing the appropriate Schifer sheet weight, several factors must be taken into consideration, including the local climate, building codes, and the structural soundness of your property.
| Wave Type | Weight per Square Meter |
| 7-wave sheet | Approximately 5.5 kilograms |
| 8-wave sheet | Approximately 6 kilograms |

Why is it important to determine the weight of slate roof
When selecting a classic wave asbestos-cement slate for your roof, you should give careful consideration to both the design of the roof frame’s roof carcass and the material itself, as slate sheets vary in size and bulk.
The strength of the asbestos-cement material increases with thickness!
High strength rates can be achieved for a roof by selecting an asbestos-cement material with greater thickness.
But because such roofing will put more strain on the frame, stronger rafter systems will need to be designed; they must be able to support the weight with some margin.
- Schifer weight;
- snow and wind loads (their parameters depend on climatic features and tilting of slopes);
- Operational loads (the weight of structures installed on the roof, people involved in installation work, cleaning or repairing the roof).
The installation of the crate with a smaller step and the use of thicker wood and boards are necessary for the improved rafter system.
This results in a considerable increase in the mass of the roof as well as an increase in construction costs.
Consequently, the construction’s walls and foundation need to be strong enough to support the weight imposed by this design.
In order to select the ideal parameters for each component of the roof, walls, and foundation structures, it is obvious that the weight of the roofing should be determined even during the construction design stage. You will need to know the weight of a slate in order to do this.
The size of the overlaps in both the horizontal and vertical directions, as well as the method of laying the elements, must be determined when designing the slate roof. This parameter is directly impacted by wind, snowfall, and roof slope inclination: the gending roof needs to be stronger than the snowfall and have more overlaps and reinforced crates.
Once the asbestos-cement material on the roof has been calculated (i.e., the necessary number of flooring elements has been determined), you can compute the roofing’s overall mass.
When it comes to cost, asbestos-cement material is among the most reasonably priced options. However, the cost savings on roofing may not outweigh the investment in rafter system components if you design an improved roof.
Main characteristics
The raw material used to make slate is a 4:84:11 ratio of Portland cement to asbestos, with the addition of water. The asbestos fibers serve as reinforcement, boosting the material’s strength and resistance to stretching loads.
Since not all manufacturers follow GOST, factors like the size of the asbestos fibers, the precision with which the cement is ground, and the final material’s density can affect a product’s strength in addition to its thickness.
There are two types of asbestos-cement roofs: one is a flat, wavy sheet with five to eight ridges.
Three categories exist for waved slate:
- In – a sheet of a standard profile, a rectangular shape 1120×680 mm;
- Wu – reinforced, designed for use in the construction of industrial facilities, is characterized by a size of 2800×1000 mm;
- UV – a material that has a unified profile, medium format (most often 1750×1130 mm), primarily in demand in civilian construction.
When designing roofs, private developers typically like to use slates with seven or eight waves. The height of the ridge and the separation between the upper points of the crest vary depending on the type of roofing material.
Popular profiles therefore have the following characteristics:
- 40/150 (the height of the ridge is 40 mm, the wave step is 150 mm);
- 54/200 (the altitude of the ridge is 54 mm, the wave step is 200 mm).
The wave height indicator shows the height of ordinary and overlapping waves; for type 40/150 and type 54/200, the extreme overlapped wave’s height is 32 mm and 45 mm, respectively.
The flooring’s seven- and eight-wave asbestos-cement element is typically 5.2 and 5.8 mm thick (profile type 40/150) or 6 and 7.5 mm thick (profile type 54/200).
Because the useful and nominal areas of the roof flooring elements differ by a relatively small amount, this species’ wave slate is highly sought after by private developers.
We investigate the specific weights of Schifer sheet weight and its implications for roofing projects, concentrating on the 7 and 8 wave sheets. These sheets are essential for roofing longevity and ease of installation because of how their weight impacts handling, the need for structural support, and the effectiveness of the installation process as a whole. By looking at these variables, we can gain a better understanding of how selecting the appropriate Schifer sheet weight in roofing applications can maximize both performance and economy.
The weight of the unified seven and eight-wave slate
The following conditions can result in a sheet with seven waves:
- Standard length – 1750 mm;
- The width is 980 or 1130 mm;
- Thickness 5.2 or 5.8 mm.
The thickness and width of the seven-wave slate leaf determine its weight; the length and profile type are the same (refer to the table below).
| Schifer brand according to GOST, sheet size | Sheet weight, kg |
|---|---|
| Type 40/150, 1750 × 980×5.2 | 18.0 |
| Type 40/150, 1750 × 980×5.8 | 21.8 |
| Type 40/150, 1750 × 1130×5.2 | 18.7 |
| Type 40/150 1750 × 1130×5.8 | 23.2 |

Shipipher eight-wave slate is made into sheets with the following dimensions:
- Standard length – 1750 mm;
- Standard width – 1130 mm;
- The thickness depends on the profile and can be 5.2/5.8 mm or 6.0/7.5 mm.
Weight characteristics of the eight-wave slate, considering the profile type and dimensions in the following table.
| Schifer brand according to GOST, sheet size | Sheet weight, kg |
|---|---|
| Type 40/150, 1750 × 1130×5.2 | 20.6 |
| Type 40/150, 1750 × 1130×5.8 | 26.1 |
| Type 54/200, 1750 × 1130×6.0 | 26 |
| Type 54/200, 1750 × 1130×7.5 | 35 |

When planning roofing work, it’s crucial to consider the mass of one component of wave roofing: each sheet needs to be lifted to the roof. If you can manage this alone with a slate weighing 18 kg, you’ll need help lifting sheets weighing 26 kg or more.
It is necessary to determine the weight of one square meter of slate in order to determine the weight of the roofing.
To sum up, anyone working on roofing projects needs to know how much schifer weighs in wave sheets seven and eight. The logistics of transportation, ease of installation, and structural considerations are all directly impacted by the weight of these sheets.
Knowing the weight is helpful for both homeowners and roofing professionals when it comes to budgeting and material and labor purchases. The distinction between wave sheets 7 and 8 can have an impact on the roof structure’s ability to support weight as well as the roofing system’s overall longevity.
Achieving the ideal wave sheet weight requires striking a balance between variables like installation feasibility, cost-effectiveness, and climate resilience. It’s critical to confer with suppliers or roofing specialists to ascertain which option best suits the demands of a given project.
