Great!
you bring you 2010 book at the meeting and you can show me exactly how the books tell me that a re-roof in not allowed.
I have a roofing contractor on this thread, that has done roofing over and over, say its allowed but you say its not.
Please bring your book. I will buy a huge yellow highlighter so you can teach me your wisdom.
BTW, the original post was for a second layer of shingles, not a coating. Stick to the topic. I will repeat myself. I said nothing about elastomeric coatings. I understand they could count as a 2nd layer, but that dog isn’t in the hunt.
