I feel so bad for you roofers in that kind of danger zone. You are who the speed limits (nail patterns and staggers etc… regulations) were made for, and you make simple desert dwelling , way hard.
As in, yea, we dont need ice and water, double overlocked by heavy synthetic, plus a metal valley, to be the norm for us semi desert dwellers. I mean fuck, we just tore up a ghetto ass California valley with no paper underneath, and now us installers should think we need 3 underlays plus a metal, in order to “feel good”, about the job? I’m still laughing
