Background & Objective

Snow Load Calculation with Product Recommendations for Roof Construction

Otto Lehmann GmbH needed a tool for the Lehmann Project Planner that would make it easier for its customers in the construction industry to calculate snow loads on roofs. The goal was to create a solution that simplifies complex structural calculations and thus helps identify the right products for snow protection systems in roofing projects.



Our Solution

Digital Tool for Professional Snow Load Calculations

We developed a calculation tool that guides users through the process of entering all relevant data. Automated features help identify missing values. Companies can select suitable products from the Lehmann Product World and request a manufacturer’s recommendation, which they can use directly when placing an order.


3D Visualization of the Roof Structure 

After entering the roof dimensions and specifications, the 3D visualization shows how the roof is constructed. This allows you to see exactly where the snow guard system will be installed.

Product Recommendations Based on Roof Structure 

The tool suggests suitable products from the Lehmann product range. Users can put together their snow guard system and make adjustments, such as to the mounting. The selection is saved and can be used to request a manufacturer’s recommendation or place an order.
