How much should this gap actually matter?
That 6% 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.

Cheapest time for flat roof replacement in either city
Shingles need warm, dry weather to seal, and demand peaks after summer storms. Booking in the slow late-fall/winter window for a spring install often earns you off-season pricing.
Where does a smart roofing budget go in 2026?
Tear-off vs. overlay, shingle tier and what's hidden under the deck decide the real number. Our editors on the trade-offs.
The do-it-right case
A full tear-off lets the crew replace underlayment, flashing and ventilation while the deck is exposed — the layers that actually keep water out. Covering old shingles with new ones costs less on install day, but the trapped heat shortens shingle life, and many manufacturers won't honor a warranty on an overlay.
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.
