Is the price difference a dealbreaker?
A 10% gap is meaningful on a project this size — about $950. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Houston.

Cheapest time for flat roof replacement in either city
Shingles seal properly only in warm, dry conditions, which is exactly when everyone else wants a new roof too — especially right after a summer hailstorm. Lock in a late-fall or winter booking for a spring install and you skip that rush.
Where does a smart roofing budget go in 2026?
Two roofs of the same square footage can price hundreds apart because of something you can't see from the ground — the deck under the old shingles. Add the tear-off-versus-overlay call and the shingle grade, and you have the decisions that actually move the number.
The value case
Architectural shingles hit the sweet spot — far more durable than 3-tab for a modest premium, and far cheaper than metal or tile. For most homes they're the right default.
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.
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.
Three habits keep a roof from costing more than it should: strip to the deck, choose an architectural shingle, and get the decking-repair rate on paper before the tear-off begins. Storm season tends to produce the lowest bids and the shortest-lived roofs.

Do roofing pros really charge more in one city?
It's not a myth — BLS data puts installer wages at about $24.2/hr in the McAllen-Edinburg-Mission area and $29/hr in Houston-Pasadena-The Woodlands. Given labor is around 60% of a flat roof replacement job's cost, that gap explains most of the price spread.
When is the cheapest time to buy flat roof replacement — and does it differ by city?
Timing doesn't change by city here — Late spring to early fall (dry, 45–85°F) is the cheapest window in both Allen and Houston, saving roughly 5–10%. Avoid mid-winter and the post-storm rush in either location, when emergency replacements push prices up.
Should I choose where to live based on flat roof replacement cost?
Rarely. The $950 difference is real but one-time, and you can often close most of it in Houston by buying in the off-season and getting tighter, apples-to-apples bids. Ongoing factors — energy prices, climate and home condition — matter more over the life of the system.
