Why does flat roof replacement cost vary across Alaska?

The three levers are local labor rates, climate zone and permit fees. In this cold-climate region, snow load and ice-dam protection matter for flat roof replacement, so proper underlayment, ice-and-water shield at eaves, and good attic ventilation are worth the extra cost.
