Information

The online shed roof calculator is designed to calculate the slope angle, the quantity and size of rafters, the amount of battens, and the volume of necessary materials. The calculations include all popular roofing materials such as ceramic, cement-sand, bituminous, and metal tiles, ondulin, slate, and others. It is possible to calculate a flat roof based on specified parameters. The calculation includes drawings in different projections and a rafter drawing with dimensions of the lower notch. Using this rafter calculator, you can accurately determine the length and slope of the roof.

The online rafter system calculator is an interactive tool for instant specification of the roof's technical characteristics. The multifunctional module helps quickly and accurately calculate the required amount of roofing, waterproofing materials, and insulation, as well as clearly outline the structural features of the rafter system. A competent, meticulously accurate online shed roof calculation minimizes accidental errors and allows you to design the perfect roofing option. Calculating the roof slope angle and other parameters is easy and fast, ensuring an accurate result.

Functions and Advantages of the Online Calculator

  • Saves time on measurement operations, helps competently calculate shed roof rafters, and develop a project for a durable and resilient roof.
  • Allows you to separately calculate the wall plate, waterproofing, counter battens, and insulation, determining the optimal slope angle, which takes only a few seconds to calculate.
  • 2D and 3D visualization options ensure the clarity of the calculation manipulations, allowing timely corrections and adjustments.
  • The ability to accurately calculate the required amount of construction materials ensures targeted use of funds, optimizing the roof construction budget.
  • The program instantly calculates the metric characteristics and the required volume of construction materials for both hard and soft roofing. The rafter calculator takes all parameters into account, including the slope angle.

Attention, Reference!

  • The width of rafters with supports or purlins is 100-150 mm, and without supports, it is 200 mm. The length depends on the slope angle but should not exceed 5 meters to avoid sagging.
  • A 30x100 mm board is suitable for the battening of a metal tile roof. Flexible or metal roofing may have a larger spacing, so use a 30x100-150 mm board.
  • The center-to-center spacing for metal tiles is 350 mm. This value can be increased for other materials.
  • Standard OSB sizes are 250x125 cm.
  • The working width of a metal tile sheet is 110 cm (overall 118 cm). The length depends on the order conditions, with a minimum of 1 meter.
  • For the wall plate, use a 50x150 mm board, and if the load needs to be evenly distributed, use a 150x150 mm timber.
  • For warm rooms, it is essential to use counter battens with a thickness of at least 30 mm, and the waterproofing must be high-quality and durable.
  • The insulation thickness for our region should be considered from 100 mm to 250 mm.

Using the calculator for shed roof calculations is a rational way to quickly and freely obtain the most accurate rafter system calculations. This online tool will help you understand how to calculate the roof slope, determine the slope angle calculation, and use the slope degree calculator for precise measurements.
