<div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif">I'm surprised this hasn't really come up for us. I can't remember the last time we ran conduit along a pitched roof other than very short runs to an eave where we penetrate the roof and soffit to run down an exterior wall. I'm guessing you are dealing with an inaccessible attic. We just about always get into the attic right from the j-box location.
