Built-Up Roof with "Mineral Surface" & Longwave TIR
Greetings from Boise! I have a customer who is very keen on having a BUR with a mineral surface assayed. I'm familiar with membranes, but completely unfamiliar with this sort of BUR... It is a "granulated" surface apparently mopped onto an underlying board material, which is on top of a layer of insulation.

I cannot imagine a reliable use for LW TIR on such a surface, but figured I'd float the question in hopes of learning something. It's not a very large (e.g. 100,000sf) job so will not support renting a SW camera.

Thanks for any input...

I cannot see you having any problem with this. The mineral surface is a good emitter and has a diffuse surface, which makes it fairly easy. LW should be fine. It does depend on the underlining board material, but it should be okay.

Thank you! I'll probably do the job just to see if we get any core samples that corroborate the TIR findings...
