Outline the roof on a photo — a drone shot, or one taken from the ground. Tegrona Lite removes the perspective by reading the tile pattern, so trapezoid and triangular roof sections work too. It takes the scale from the tile size, fills the roof with panels, and exports an A4 spec sheet for the customer. Free, no account. The web version runs entirely in your browser with nothing uploaded; native apps for macOS, Windows, iPad and Android.
