Free high resolution photo of a corrugated fiberglass greenhouse roof. This roof is quite old, and you can see dirt gathered in the furrows of the corrugated fiberglass surface. I think it was once yellow in color, but now it has faded to an off white color. The photo is shot at an angle so the ridges are forming diagonal lines. Great background image for a web page or blog, desktop wallpaper or texture for Photoshop. Free picture for any use.
