Use Apple or Google maps and satellite imagery to easily locate and measure a potential roof for suitability of a solar-PV or thermal installation. Use zip/postcode or address to locate the desired roof. Quickly identify the roof to be measured. Easily indicate the surrounding rectangle of the roof. Enter the roof's pitch. Instantly get the roof width, ridge-to-gutter distance, azimuth and surface area. Using latest satellite technology, it is easy to 'box' a roof with simple drag-and-drop techniques.
