  2. 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.

  3. Reflective surfaces (climate engineering) - Wikipedia

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

    If all urban, flat roofs in warm climates were whitened, the resulting 10% increase in global reflectivity would offset the warming effect of 24 gigatonnes of greenhouse gas emissions, or equivalent to taking 300 million cars off the road for 20 years.

    Home Advisor puts the cost to paint the exterior of a single-story, 2,000-square-foot home between $2,000 and $8,000, ... and storm windows as well as the roof and gutters. Prep Work.

  5. Passive daytime radiative cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_daytime_radiative...

    When compared to the reflective surfaces approach of increasing surface albedo, such as through painting roofs white, or the space mirror proposals of "deploying giant reflective surfaces in space", Munday claimed that "the increased reflectivity likely falls short of what is needed and comes at a high financial cost."

  6. Passive solar building design - Wikipedia

    en.wikipedia.org/wiki/Passive_solar_building_design

    A roof pond passive solar system, sometimes called a solar roof, uses water stored on the roof to temper hot and cold internal temperatures, usually in desert environments. It typically is constructed of containers holding 6 to 12 in (150 to 300 mm) of water on a flat roof.

  7. Flat roof - Wikipedia

    en.wikipedia.org/wiki/Flat_roof

    A flat roof is the most cost-efficient roof shape as all room space can be used fully (below and above the roof). Having a smaller surface area, flat roofs require less material and are usually stronger than pitched roofs. [26] This style roof also provides ample space for solar panels or outdoor recreational use such as roof gardens.

  8. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Light-colored roof shingles and reflective paint. Often called cool roofs, these help to keep attics cooler in the summer and in hot climates. To maximize radiative cooling at night, they are often chosen to have high thermal emissivity, whereas their low emissivity for the solar spectrum reflects heat during the day. Metal roofs; e.g ...

  9. Insulative paint - Wikipedia

    en.wikipedia.org/wiki/Insulative_paint

    Insulative paints, or insulating paints, are a specially designed type of paint in which can be used to coat a surface (e.g a wall) to reduce heat transfer as well as increase the thermal insulating property (R-value in order to aid cooling and heating efforts for example [1].
