How much should this gap actually matter?
That 3% 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
The material dictates the season (shingles need warmth to seal), but the price is set by demand, and demand spikes after every regional hailstorm. Booking your spot in the quiet winter months for spring work avoids that spike.
Where does a smart roofing budget go in 2026?
The real cost of a roof comes down to three decisions: tear-off or overlay, which shingle tier, and what condition the decking is in. Our editors weigh in.
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
The surprise that wrecks a roofing budget is rot in the decking, and you rarely see it until the old shingles come off. Fix the price per replacement sheet in the contract before the crew starts, so a low bid can't quietly climb once the deck is open.
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.
Whatever the headline bid says, the roof that lasts is the one installed on a bare, sound deck with the repair price fixed in advance. Overlays and open-ended decking charges are where a cheap quote turns expensive down the line.

When is the cheapest time to buy flat roof replacement — and does it differ by city?
The best window is the same in both Arlington and San Antonio: Late spring to early fall (dry, 45–85°F), when demand drops and installers discount to keep crews busy — typically 5–10% off peak pricing. The most expensive time anywhere is an emergency replacement during mid-winter and the post-storm rush.
Should I choose where to live based on flat roof replacement cost?
Not really — the $250 gap is one-time, and smart timing and tighter quotes in Arlington can shrink it. Factors that compound over time, like energy prices and home condition, deserve more weight than a single upfront difference.
