   Metal roofs emissivity is better at reflecting solar radiation at 10%–75% depending on the color choice, compared to asphalt roofs that reflect 5%–25% depending on their color. Over the lifetime of the metal roof they keep 95% of the reflective capacity compared to other roof types that lose 20%–40% of their reflective capacity.

   en.wikipedia.org/wiki/Self-Framing_Metal_Buildings

   Building width: 3 m (10' +/-) to 10 m (32' +/-) is common. Width is primarily limited by the capability of the roof panel to support the applied gravity loads (e.g. self-weight, snow) and wind uplift loads. In taller buildings, the wall panel may be a limiting factor to width due to buckling of the unsupported wall panel length.
