Reflective Roof Paint

I'd be interested in hearing from anyone who has used or decided not to use solar reflective roof paint. I live in a hot climate and am getting my roof done in the next couple of weeks. Will be painting it white definitely, but interested in the new technologies. Are they worth it on comparison?

Hi Vivienne, roofs in the states are rated by their Solar Reflective Index SRI. Learn more at http://www.coolroofs.org/coolroofing.html

There are lots of hucksters peddling questionable products when it comes to reflective paints and radiant barriers. Usually its not worth paying any extra for a special paint for this purpose. Its tough to beat the simplicity of a Bright White color.

I should have added that when replacing a roof covering, it can be worth looking into adding insulative sheathing to the roof deck in both cold and hot climates.

Thanks! I do have full roof insulation, wide eaves and whirly birds in the roof (do you have them in the US?). So passage of hot air out is not a problem. I even put in closeable ceiling vents to keep airflow during summer - our biggest problem is humidity from Sept - March here in the sub-tropics.

I've seen solar reflective paint as an option within multiple companies here in Queensland. I guess I'll read the spec sheets and compare plain white paint to solar paint. Currently, the roof is a dirty forest green.

Appreciate you comments thanks!
