Heat inside your bus, white roof vs other lighter colors?

Has anyone noticed a big difference in interior temperature when going to a white roof from another paint color? I'm considering a white roof but would rather another color.

Clayton, There are several different threads on this subject, and like anything, there are several opinions on how well it works. These threads are in a variety of different threads, but a search for them should make it easier to find. I've read that white is the best to reflect heat, but I think dark colors attract heat better. (I'm more concerned with the heat)
Personally, I will most likely use one. I'll wait till I get to that point before picking a brand. Being that you are located in 'Far North Texas' (lol) you might want to check out all the info. Let us know what you decide, your experience, how it turns out, and of course pictures.

I'm in the far North but will often be in the far South, but even up here it can be 100 degrees in the summer. Its kind of an interesting topic as its difficult to test this. I am doing the body work right now. Soon it will be painted, its super exciting.

On SuperDave's bus he tested the temps and the flat white on the roof was cooler than the other colors on his bus by at least 10 degrees or so.

I used BusKote (Hi-Tech) on the top originally - I painted the front part with the BusKote (it was white) and there was a noticeable difference touching the top of the bus.
Right now the bus roof is green - it's been raining here for a few days - so as soon as there is a dry day in site - I plan to prime / BusKote - then Flexiseal. The company said it works. So I will test the temperature inside and out - before and after.

A white roof will noticeably reduce heat transmitted through on any vehicle.

Yes.

There's plenty of threads on this exact subject here and on other forums (fora?). Or make a tropical roof, like the Saudi MC5 buses and Series 1 Land Rovers used to have, then sunlight doesn't touch the bus roof at all. Almond surprisingly has almost as good solar reflectivity as plain gloss white: Solar Reflectivity (R) & Solar Reflectance Index (SRI) by Color – Dean Steel Buildings, Inc.

But with a white roof you won't be camoflauged when the helicopters come.

The helicopters use FLIR anyhow.

Yeah, I wouldn't want to have to hide from helicopters. However, there are lots of hiding spots out here. I'll just paint my bus to match the FEMA camp buses.

I'd rather be insulating a Chinook helicopter instead of a bus.
