We use steel roofing on our production coops and custom chicken coops that comes in a variety of colors.
This roofing uses an armor-shield manufacturing process that incorporates warm roll-forming of pre-painted sheet steel with clear coated edges. In a recent study, U.S. Steel has demonstrated that warm roll-forming not only improves the formability of the paint film, but also improves the formability of the underlying metal coating. In fact, it is believed that tension-bend cracking on the pre-painted GALVALUME sheet could be virtually eliminated by using flexible paint systems and warm roll-forming practices.
In addition, because metal has a low thermal mass, heat is not absorbed into the roofing material and then transmitted into the coop. In fact, the Florida Solar Energy Center states that metal roofing absorbs about 34 percent less heat than asphalt shingles.
The painted metal roofs are even more energy efficient that plain metal roofing. (yes, even black roofing!) These roofs not only reflect solar energy, but also re-emit most of the solar energy that the coop absorbs.
