Why you guys gotta disagree and make my life hard?
I won't be painting until Fall anyway so we have plenty of time to figure out what is best.
For arguments sake: My house is in the desert, It is 112 today and is pretty hot all summer. It gets below freezing in the winter but we do not get a lot of rain. On my eves I have a clay tile roof and good rain gutter on most of the house. Most of the paint will be on the under side of the eve and a 2x6 on the face.
Here is a pic of the house. Just look beyond the projects.
