Yeah most flat roofs are modified bitumen.
Lots of tar and gravel left on the older stuff and on commercial too.
Not uncommon to see Rubber However on the newer construction though.
Come to think of it I am seeing more modified bitumen trending recently.
Do they hot mop by you ?or are they into the future with the Good year stuff
Please do not say roll roofing

Built-up roof with craze cracking of the surface asphalt layer caused by long-term shrinkage.

If Modified Bitumen and BUR without gravel is coated and regularly coated (5 years or so)with a good aluminum coating they will last much longer. Don't coat immediately but wait a couple weeks to let some of the oils to evaporate. I have seen that ponding water and UV are the enemies of flat roofs. Coating as Marcel said if the membrane is not cracked will prolong its life also.
