Master Electrician Teaches Son a Lesson to never Drill through a Roof as you’re working, thoughts?

All right, Chris. So, what did you learn just this morning? >> Never penetrate on a commercial roof. >> Never penetrate through a commercial roof. Do you know why? >> Because it voids the warranty. Call the roofer, the licensed roofer. >> Well, yes. Because a lot of our insurance policies do not cover for water damage. You have to make sure of that if you cause a flood because you penetrated it into a commercial roof. >> Yeah. >> The reason is because these commercial roofs are rubberized. >> Mhm. and they have a special adhesive, they have a special cleaning, a special technique. It's not rocket science. It's just that the installer is certified. So, if you cause a problem drilling through a commercial roof, it's kind of your ass. Roofers will put in what they call a pitch pocket, guys. A pitch pocket is like a curb or a device that's already penetrated. They do that and then there's either an opening or there's a a place where we can drill through without jeopardizing the warranty and possibly leaking into the roof. For example, a rooftop unit for an air conditioning. We as electricians will never penetrate through the roof. Yep.
