TPO Membrane: Costs, Lifespan and Alternatives

Yes. Low-slope sections on Chinatown buildings need a membrane or coating system rather than shingle laid flatter than it is rated for, and they are quoted separately from the pitched roof.

In inland conditions, composition shingle runs roughly fifteen to twenty-five years, tile underlayment twenty to twenty-five, and coatings seven to fifteen depending on the system.

Two visits a year: clear valleys and gutters before the rains, then check flashings after the first real storm. In Chinatown that matters most because asphalt dries out and sealant pulls back from penetrations years before the field wears through.
