White Roof Paint Energy Savings

Additional cool roof costs include specialized materials and labor.

White roof paint energy savings.

If your energy costs are determined by on peak and off peak rates print out results of separate estimates with on peak and off peak rates for the same roof. Apoc cool roof restoration systems deliver high solar reflectivity and thermal emittance which significantly reduce roof temperatures. Solar reflectance is the most important characteristic of a roof product in terms of yielding the highest energy savings during warmer months. The misunderstanding is that while white roof paint can have some initial reflective value it does not eliminate heat nor does it have any waterproofing abilities.

Black surfaces in the sun can become up to 90 f hotter than the most reflective white surfaces. Atmosphere a white roof should act like a natural anti warming device while also reducing your energy costs by keeping your house cool in the summer. Steven chu the u s.

It features dirt pick up resistance dpr technology which prevents dirt and dust buildup keeping the roof whiter and more reflective longer. Add the federal tax credits available for cool.

Judge what fraction of the savings with on peak rates is appropriate. Henry 687 100 acrylic enviro white extreme elastomeric roof coating is a premium high solids white reflective roof coating. For the average 1 000 square foot residential roof a yearly energy savings of 0 50 per square foot yields about 500 annually. The higher the solar reflective value the more efficient the product is in reflecting sunlight and heat away from the building and reducing roof temperature.

Manually compute the difference in savings to compare the two non black roofs. It is commonly mentioned as a way to reduce the global warming effect or conserve energy. Switching to a white roof can actually reduce energy use by about 20 percent in hot sunny weather according to the lawrence berkeley national laboratory heat island. Major roof costs include upfront installation materials and labor and ongoing maintenance repair recoating and cleaning.

Not only that you get to save the planet. Secretary of energy and a nobel prize winning scientist has said that painting roofs white or another light color would help to reduce global warming by reflecting sunlight back into space it would be like removing every vehicle from the planet for 11 years.
