These are not photographs of our own work, and we do not present them as such. They are licensed images chosen because they show the things this site argues about — panel runs and valleys, snow releasing in sheets, retention bars, ice at an eave. Where a caption describes what is happening in a picture, it describes that picture.
Illustrations
The fifty-year timeline graphic and the site mark are original work produced for this site and are not derived from any third-party image.
Data
Every cost figure, service life and pitch factor is attributed on the cost page, with a note on what each figure covers and what our fifty-year comparison deliberately leaves out.
