What roofing pros earn in each metro

Cheapest time for flat roof replacement in either city
Why summer costs more: it's the only stretch shingles seal reliably, so every storm-damaged roof in the region is competing for the same crews. Reserve a spring slot during the slow winter season and you're not in that queue.
Where does a smart roofing budget go in 2026?
Roofing budgets swing on decisions most homeowners don't think to ask about — overlay vs. tear-off, shingle tier, deck condition. Our editors break down each one.
The do-it-right case
Pay for a full tear-off and quality underlayment, flashing and ventilation. An overlay saves money today but traps heat, voids some warranties and costs more at the next replacement.
The value case
For a typical home, the architectural shingle is the default that makes sense. It outlasts 3-tab by a wide margin at a modest premium, and it spares you the cost of metal or tile that most roofs never need to justify.
The risk case
Nail down the per-sheet decking rate in writing before anyone climbs up. Soft or rotted plywood is the most common mid-job discovery, and without an agreed number the crew names the price after they've already found the damage — turning a cheap quote into an open tab.
Full tear-off, architectural shingles and a written deck-repair rate protect you from the two big risks — hidden rot and warranty gaps. The lowest storm-season bid is rarely the cheapest over the roof's life.
