Reflective Roof Energy Savings

Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.

Reflective roof energy savings.

A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. For anyone who may not know a reflective roof coating saves energy in your building by reflective uv rays back into the atmosphere. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. Cutting energy use with reflective roof coatings savings are found in all climates and conditions.

Tile roofs are also fairly more expensive than asphalt shingles. Other brands of solar reflective paints as well energy saving asphalt shingles are priced similarly to traditional paints and shingles. Most roofing systems absorb uv rays and that heat is transferred into the building. This means in the summer you have to run your ac more to heat the building just because the sun is shining.

Differences in the level of new versus old insulation appear to have a significant. Metal roofing is one of the most effective cooling materials but it is more expensive for materials and installation than asphalt shingles. If not your energy savings from applying a reflective roof coating could range anywhere from 20 to 70 when it s all said and done. Reflectivity or albedo is the hemispherical reflectivity integrated over a particular wavelength band of the.

Surface solar reflectivity is measured using a precision spectral pyranometer with the device alternately faced. However if you live in a hot climate that experiences warm temperatures and sunny days for a substantial portion of the year you can expect energy savings of up to 70.
