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?
Tear-off vs. overlay, shingle tier and what's hidden under the deck decide the real number. Our editors on the trade-offs.
The risk case
Budget for the unknown: rotten decking found at tear-off is the most common surprise. Get the per-sheet repair rate in writing up front so a "cheap" bid doesn't balloon mid-job.
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
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.
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.

Yes — and the wage data shows it. A skilled installer earns about $24.2/hr in the McAllen-Edinburg-Mission area versus $28.4/hr around San Antonio-New Braunfels (BLS metro wage data). Since labor is roughly 60% of a flat roof replacement job, that wage gap is the biggest reason the installed prices differ.
When is the cheapest time to buy flat roof replacement — and does it differ by city?
It doesn't vary by location — Late spring to early fall (dry, 45–85°F) is the discount window in both Celina and San Antonio (roughly 5–10% off), while mid-winter and the post-storm rush tends to be the most expensive in either city.
Should I choose where to live based on flat roof replacement cost?
That would be a stretch. $850 is a one-time difference, not an ongoing one, and off-season buying plus apples-to-apples bids in San Antonio can close a good chunk of it. What matters more long-term is energy costs, climate and the condition of the home.
