A roof can do much more than protect.
When we think of roofs, we think of protection from the elements and shelter. We want to protect ourselves from the sun, wind, rain, and snow and we don’t want water or drafts leaking into our buildings. But a roof can do much more than protect. Roofs can also cool our buildings by transferring energy from the building to the night sky, and provide heat by transferring solar energy to the interior of the space by convection, conduction, or radiation.
