will dull black metal absorb more heat in summer than shiney black? advantages vs disadvantages with each??
David Stermer
Hi Dave, Thanks for your question about metal roofing. My understanding is that the gloss level has a minor effect on the solar reflectance. Much more important are the pigments that are used in the paint. A matte finish reflects practically the same amount of solar energy as a glossy finish, it is just diffuse - going in all directions. A glossy finish reflects the solar energy in an aligned fashion. The gloss level is primarily an aesthetic quality. Regards, David
