Field notes
The workflow combines address lookup with IGN terrain, orthophoto, and topographic data to construct a neighborhood model. Users can vary gust direction and speed, roof material, and pitch, while an optional house photo is said to help estimate roof details. The page also describes sharing a view with a roofer, building manager, or insurer; its calculation method is explicitly described as a simplified version of Eurocode 1.
