    Pyramidal roof is a pyramid shaped hip roof, constructed on top of a square base, it is characterized by a high degree of aerodynamics.

    To create this type of roof framing it is recommended to carry out simple pyramid roof calculation with online calculator Kalk.pro. You only need to enter your initial data and click "Calculate". Then you can save the calculation results in a convenient format, or send by email, work with drawings and interactive 3D model.

    To build high-quality structures it is necessary to accurately determine the parameters of the rafters, draw the layout of a pyramid hip roof, to calculate the amount of building material. You can use the Pythagorean tables, complex mathematical formulas and equations or to resort to the experience of a specialist.

    Can all be calculated independently, but to prevent errors in the construction process, it is best to use multifunctional program presented on the website. Alternative simple variant of a time-consuming calculation is the calculation of the hipped roof calculator kalk.pro online.

    The benefits of kalk.pro pyramid roof calculator 

    Using the program allows you to save much energy, time, money. Proposed construction pyramidal roof calculator has features:

    • convenience, accessibility of use;
    • free calculations, simulations;
    • the maximum accuracy of calculations;
    • calculations according to the rules, requirements and norms;
    • the formation of an interactive 3D model (project) of the finished roof;
    • the creation of the necessary detailed engineering drawings of all elements of the pyramidal roof, for example, the plan of the hip rafters of the roof, and the whole system;
    • the choice of parameters, including the type of roof and the units of measurement (mm, cm, m, ft, inch).

    An important aspect of the work program is a detailed project resulting from calculations and simulations. Pyramid roof, drawing which will be submitted after carrying out the relevant calculations, will have the exact dimensions of every detail for a reliable and robust roofing truss system.

    How to calculate pyramid roof?

    Pyramid hip roof calculator helps to determine the required amount of material for the construction and dimensions of key elements. To obtain the result you need to enter information about the building and the roof width, the length, the overlap material at the top and side:

    • roof dimensions: height, size of the overhang;
    • house measurements: length + width, thickness and height of walls, width + thickness of wall plate (inferior purlin);
    • measurements of the rafters: depth washed down from the rafters, the width of the rafters, the thickness, the distance or pitch between them;
    • the estimated thickness of counter-battens and sheathing settings;
    • information on the roofing material.

    In order to accomplish such a task, how to calculate the area of a pyramidal roof or its elements, the program will take less than a minute. The user just need to enter appropriate parameters of the structure.

    The results of calculations of pyramidal roof calculator 

    After the calculation of the calculator generates all the data required for the procurement of materials, start of construction of the roof structure:

    • the sizes of all rafters (jack, king common, etc.)
    • the length of the ridge and the eaves
    • square pyramid hip roof
    • the volume of timber for construction, the amount of material for the roof;
    • detailed drawings
    • 3 d model

    As a pyramidal hip roof in natural form is a three-dimensional shape (a pyramid), the program calculates not only the perimeter of the base, the size of the planks (planes), but the total area of the building.

    Easy to use software available to users of the network – the main advantages of online programs. It greatly facilitates the process of building the roof, so as to design and construction of the design you don't need the services of professionals. Use a functional tool right now!

    Using our pyramid roof calculator - the key to a durable roof and aesthetic appearance of your home.

    Another great calculator is able to calculate the classical hip roof.
