Our online Gutter System Calculator is designed to provide quick and reliable calculations for optimizing your gutter system based on roof area and rainfall intensity. By entering data about your roof area and selecting its type, you can determine the optimal downpipe diameter and the required number of system components.

Steps to use the Gutter Calculator:

  1. Select the method for calculating the roof area: either calculate it online or manually enter the value.
  2. Specify the roof’s geometric characteristics (available types: gable, hipped, mansard, or flat).
  3. Choose the method for calculating the gutter system: either manually set the number of outlets or calculate them according to building standards.
  4. Click the "Calculate" button to get the results.

The calculation results include:

  • The optimal number of downpipes and their ideal diameter.
  • The total length of gutters and the number of gutter brackets required.
  • The number of drain outlets and their brackets.
  • The number of gutter end caps, elbows, and downpipe bends.

The downpipe diameter is calculated based on the roof area and the rainfall intensity in your region, ensuring efficient water removal and protecting the building structure from excess moisture.

Our Gutter System Calculator helps you design a drainage system tailored to your roof area, optimizing costs and ensuring reliable protection for your home against moisture damage.
