Abstract
A roofing board, such as a polyiso insulation board, includes first and second surfaces, where the first surface is lighter in color than the second surface. This allows the roofing installer to choose which of the surfaces to expose to the atmosphere, the lighter surface being cooler than the darker surface. The lighter surface may have a solar reflectance greater than the darker surface. A roofing membrane is then adhered or otherwise attached to the exposed surface.

A generally reversible planar roofing board for positioning on a roof deck and for receiving a membrane, the membrane able to be adhered to the roofing board using an adhesive, the roofing board comprising:
- a first planar surface including a first composition and a first sun energy absorbing characteristic;
- a second planar surface including the first composition and a second sun energy absorbing characteristic;
- a layer separating the first planar surface from the second planar surface;
- wherein in a first configuration the first planar surface is positionable adjacent the roof deck and the second planar surface is positionable away from the roof deck;
- and wherein in a second configuration the first planar surface is positionable away from the roof deck and the second planar surface is positionable adjacent the roof deck;
- further wherein the second sun energy absorbing characteristic differs from the first sun energy absorbing characteristic.
A method of applying a roof surface, wherein a foam insulation board is fixed to a roof deck;
- wherein said foam insulation board is a generally planar foam board having a first planar surface and a second planar surface;
- said first planar surface configured to be affixed to said roof deck and configured to be adhered to a membrane layer, said second planar surface configured to be affixed to said roof deck and configured to be adhered to said membrane layer, wherein light absorption characteristics of said first planar surface are different than light absorption characteristics of said second planar surface, said method comprising:
- fixing said foam insulation board to said roof deck with said first planar surface or said second planar surface positioned toward the sun for sun energy to be absorbed by either of said first and second planar surfaces, the foam insulation board being a facer-less board or a board coupled to a first facer defining the first planar surface and a second facer defining the second planar surface, wherein one of said first and second planar surfaces are exposed to an atmosphere, providing an exposed surface;
- and
- adhering or attaching a roofing membrane to said exposed surface.
