2. Reflective surfaces (climate engineering) - Wikipedia

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

   Steep sloped roofs have less of a problem with dirt accumulation because rainwater can more easily wash away dirt and debris. Some cool roof surfaces are “self-cleaning” which means they shed dirt more easily and may better retain their reflectance. Cleaning a cool roof can restore solar reflectance close to its installed condition.

3. Radiative cooling - Wikipedia

   en.wikipedia.org/wiki/Radiative_cooling

   Cool roofs combine high solar reflectance with high infrared emittance, thereby simultaneously reducing heat gain from the sun and increasing heat removal through radiation. Radiative cooling thus offers potential for passive cooling for residential and commercial buildings. [5]

4. Roof coating - Wikipedia

   en.wikipedia.org/wiki/Roof_coating

   This means a roof coating actually becomes the top layer of a composite roof membrane and underlying system. As such, the roof coating is the topmost layer of protection for the membrane, receiving the impact of sunlight (both infrared and ultraviolet (UV)), rain, hail and physical damage. Roof Coatings should not be confused with deck coatings.

5. Radiant barrier - Wikipedia

   en.wikipedia.org/wiki/Radiant_barrier

   This is different from the "cool roof" strategy which reflects solar energy before it heats the roof, but both are a means of reducing radiant heat. According to a study by the Florida Solar Energy Center, [ 8 ] a white tile or white metal cool roof can outperform a traditional black shingle roof with a radiant barrier in the attic, but the ...

6. Roof - Wikipedia

   en.wikipedia.org/wiki/Roof

   A roof (pl.: roofs or rooves) is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. [1] A roof is part of the building envelope.

7. Flat roof - Wikipedia

   en.wikipedia.org/wiki/Flat_roof

   A small Butynol roof installation on a residential flat roof in New Zealand. Butynol roofing is a type of roofing material made from synthetic rubber, specifically butyl rubber. It is widely used in New Zealand and other parts of the world for flat and low-slope roofs due to its exceptional durability, flexibility, and waterproofing capabilities.
