What the quoted rate covers

Normally: Membrane or shingle assembly and underlayment; Insulation and vapour control to specification; Flashing, edge metal and standard penetration details. Normally not: Structural deck repair discovered after tear-off; Fall-arrest anchorage and guardrail systems; Extended manufacturer warranty inspections; Snow and ice removal during the work.

What moves roofing pricing here

Penetration count: every curb, drain and vent is a detail priced individually, and details are where leaks and cost both live. Insulation R-value: energy code minimums have raised commercial roof insulation cost materially over the last decade. Tear-off versus re-cover: disposal and unexpected deck repair are the two largest variables. Access and staging on an occupied building adds hoisting and protection cost.
