Forum Title: Need Tear Off Advice
We haven't torn off a flat commercial roof in 18 years, and it was 10 years before that that we did another one. I'm like a newbie on tear off and could use some advice. One roof is 320 SQRS gravel, the other is 450 SQR mod bit. Both have 2 layers. The mod bit has steel deck and the gravel BUR has concrete deck. We will put 1.5? SPF on the concrete deck after priming, and Densdeck and 1.5? foam on the steel deck. Single roof cutter vs. double? Are we better off buying 2 singles rather than 1 double cutter? Cut roof into 2?x2? squares, I assume? On the steel deck, adhering the Densdeck is a lot more expensive, is there any reason that is favorable to mechanically-fastened?
