Kalk.pro is online shed roof calculator (single slope, pent roof, skillion) - program determines basic material consumption for roof building, roofing underlayment volume, all quantitative and dimensional values of the shed pent roof truss system:

  1. Dimensions and area of a shed roof, materials quantity for it, the roof angle (pitch);
  2. Number of rafters and their dimensions;
  3. Roof battens (lath) – volume and number.
  4. Other important dimensions of the  truss system

Kalk.pro provide dimensional calculatios only,  it doesn't perform any structural calculations (load-bearing) You are responsible for ensuring  that your roof meets all local building codes and laws (international) and that your structural design is ok (your roof construction is capable of resisting all applied loads).

 

You need to calculate shed roof online calculator?

Measure and define the main parameters of the house with a pent roof. To start select the type of roof - solid or soft roof (this will depend on the type of sheathing). If the material will be chosen roofing material, then the calculator additionally calculates the OSB sheets needed to create the underlay material. When calculating the number of swaps the calculator takes into account the location of the private dock of the leaves on oberste and obiskov from the already stacked sheets.

Attention! We ask you to choose carefully the units of measurement, as well as to control data input - it must be in the same units of measurement.

Do not break your head over how to calculate roof area and amount of building materials. Just make the original data in the corresponding Windows, select unit, then press "Calculate". In the end, you will receive a detailed calculation of the size shed roof and its elements, the volume of necessary materials.

Also we invite you to calculate the parameters of each individual truss legs on a separate calculator rafters of a shed roof, and to obtain drawings with printed sepilok and other important dimensions and characteristics.

Online drawing, 3D visualization - all for your convenience

Calculator shed roof specially designed to simplify working with data. The calculation results are immediately displayed on the tab of drawings. The drawing shed roof is given in several variants – planar and volumetric representation for a more visual display of the future of the roof structure.

Again, for clarity, the tab "3d view" shows a shed roof in 3D. You can view every detail in detail, to enable and disable elements of the roof, zoom in, rotate – any interaction with a ready-made design according to your source data.

Totals calculate shed roof you can save, print, fold mail, and also share in social networks.
