Which IIRC is the same for all ladders, it's something to do with vectors.Good ladders have the lean angle posted on them.
Apparently the problem is that the metal gets too hot and damages the wood roof structure with too much heat and humidity. So that is why white, maximum reflection. But with the foam it would not matter because the foam would stop the heat. So yes tint the paint would be much nicer. I'm thinking red wouldn't be much hot than brown now.
I'm not so sure another 1-2" of foam is worth my pocket book. Not sure if R values work that way, 1" of foam is surely much better than no foam. But will be 2" be twice as nice? It's another $320.
