How much should this gap actually matter?
That 2% gap is small — for flat roof replacement it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

What roofing pros earn in each metro
Labor is about 60% of a flat roof replacement bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

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
Skipping the tear-off means burying whatever's failing underneath, and a second layer bakes the shingles from below until they curl early. Doing it properly means stripping to the deck, then paying for real underlayment, flashing and airflow — the work that sets how long the roof lasts, not just how it looks the first week.
The value case
Architectural shingles sit between bargain 3-tab and premium metal or tile, and for most houses that middle ground is exactly right. They carry longer wind and wear ratings than 3-tab for a small step up in price, without the four-figure jump metal or tile demands.
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.
Insist on tear-off over overlay, get the deck-repair rate in writing before work starts, and lean toward architectural shingles. Skipping any of the three tends to cost more later than it saves now.
