    There is a difference between mirror like reflection and diffuse reflection. Mirror reflection is what you get with metal roofs which beam the sun directly to a target resulting in one spot being blinded. Diffuse reflection will spread it around, resulting in more light all around which is what we can handle as humans.

      Can mostly handle. Snow blindness is a thing, and that’s all diffuse reflection too, not specular. But it’s unlikely a roof would be such a problem.
