The cause of the Universal Studios fire…

“Workers had been using the blowtorch early Sunday to heat asphalt shingles to apply to the roof, Los Angeles County Fire Chief Michael Freeman said Monday. They finished around 3 a.m. and followed policy of standing watch for one hour, then left for a break, he said.”

In LA in June you need to torch shingles to get them to lay down!?
for some reason something struck me funny about the 1 hour policy. I just imagine some guys sitting around at 4:00am in the dark saying "Looks good to me. Look good to you? Let's go get some coffee". I don't know anything so I guess that's how it's done.
Sorry to bump the thread again but I'm wondering if a thermal imaging camera is warranted in a case like this.
I think it was reported wrong. I would venture to say they were putting down torchdown and the reporter did not know the difference.
Im so paranoid i wait 2 hours and even drive by later.
I may use a torch for the main work, stop and do detail work then clean up so i have lots of time to watch before i leave.
For those not familiar with the product or it's installation; torch down is like 90# felt paper, three feet wide, covered with mineral. It has an adhesive tar applied to it's down side in a solid state.
The tar is activated, after each course is laid, by running a large flame over it, from a propane torch with an opening about 3" diameter.
It has excellent adhesive and sealing qualities, can be applied to 1/12 pitched roofs. Has a long life too. The mineral and the excellent adhesive help a lot with it's longevity.
