Heat Reflective Roof Paint
Has anyone nailed down a roof paint that seems to be the best ?:banghead:

Plain old flat white paint is the most reflective.

All white paint is basically 90% reflective. Flat white has less chance of hot spots because it reflects it more uniformly.

Those reflectivity numbers (given with paint codes usually and named LRV) are architechtural guide lines and are used to measure how bright surfaces will be once illuminated by a light source.
It doesn't pass judgement on the radiant heat being reflected which is what is interesting for roofing materials. Just my 2 cents... ;) |
I used Rustoleum Professional 242256 gloss white oil-based enamel with Hy-Tech Thermacels ceramic insulation powder mixed into it, rolled on with a 4" short-nap roller. So far, so good. I don't know how much difference the pixie dust makes, but it can't hurt it, and any slight benefit is worthwhile.

This is a pretty basic question/subject. It isn't rocket science. https://www.scientificamerican.com/a...se-color-heat/ |
Someone did an experiment on it. There is a thread somewhere.
Basically "white elasomatric white roof sealant paint" from Lowes or home depot was the best result for the money. Search my profile, I can't get link from phone. Sent from my BLU LIFE ONE X using Tapatalk |
Right. White elastomeric roof paint. Kool Seal is one brand but there are a ton of different brands. All pretty much the same.

Nice!
