2. Reflective surfaces (climate engineering) - Wikipedia

   en.wikipedia.org/wiki/Reflective_surfaces...

   To qualify for a rating, roofing materials must have a solar reflectance of at least 0.65 and thermal emittance of at least 0.90. As many as 10 points may be awarded for 1–100 percent roof coverage with either vegetation or highly reflective materials or both.

3. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   Wood is a poor insulator and so it conducts heat from the radiant barrier to lower surfaces of said wood, where it, in turn, sheds heat by emitting IR radiation. According to the US Department of Energy, “Reflective insulation and radiant barrier products must have an air space adjacent to the reflective material to be effective.” [9]

4. Roof coating - Wikipedia

   en.wikipedia.org/wiki/Roof_coating

   A 35 °C (95 °F) heat reduction was observed on this modified bitumen roof with a white, reflective roof coating. Roof coatings are seamless and when installed correctly, can solve roof leaks on almost any type of roofing material. There are exceptions: "professionals do not recommend using cool coatings over existing shingles.

5. Flat roof - Wikipedia

   en.wikipedia.org/wiki/Flat_roof

   Inherently cool roofs: Roof membranes made of white or light colored material are inherently reflective and achieve some of the highest reflectance and emittance measurements of which roofing materials are capable. A roof made of thermoplastic white vinyl, for example, can reflect 80% or more of the sun's rays and emit at least 70% of the solar ...

6. List of commercially available roofing materials - Wikipedia

   en.wikipedia.org/wiki/List_of_commercially...

   The outer layer of a roof shows great variation dependent upon availability of material, and the nature of the supporting structure. Those types of roofing material which are commercially available range from natural products such as thatch and slate to commercially produced products such as tiles and polycarbonate sheeting. Roofing materials ...
