Architectural Illustration and the Metal Roof

One of the challenges of architectural illustration, is the representation of the many finish materials used in construction. Couple that with the complexities of natural atmosphere, sun, sky radiance, weathering of materials, and landscaping, and you have an even bigger challenge. Perhaps one of the most difficult materials to render is the silver colored standing seam metal roof.

There are several tricks that can prove to be very helpful. Do not use a silver or gray color, use a very desaturated blue. This will emulate the blue radiance from the sky. Constantly vary the color from dark to light, this will develop the matte reflection in the material. Copy and mirror architectural elements such as gables onto the metal and reduce the opacity to create subtle reflections. Lastly, paint dark seams next to lighter sections of the roof, and light seams next to the dark sections of roof. In the end, it takes a lot variation between light and dark, in just the right places, to make it work. Engaging in real world study of metal roofs under different lighting conditions will help you understand the subtleties of the material in your mind. So just have fun, experiment, and paint some metal!
