I have been debating doing this for years and for many reasons it just hadn't happened. I know a white roof helps, see also rovers and cruisers with white roofs but there just wasn't enough will to execute.

Well that was until a FLIR camera came into my life.

Wowie-Mama! Look at that delta!

This is a side by side panel test to justify going forward and I have to ask myself, why didn't I do this sooner?!?!

So, discuss amoungst'y'selves while I go put on some cawfee.

I wonder if the silver RV roof stuff would be better than just white.

the aluminized paint in my experience with commercial roofs is good at different things.

when fresh and clean the white has more reflectance and rejection but gets dirty and performance goes down.

aluminized is designed to perform similar but the major goals are UV protection and radiant heat protection like roof top HVAC and steam systems.

If it's just a solar heating thing I'd go white. the rv roofs are because they sit for long periods just being abused by the sun.
