Is the price difference a dealbreaker?
A 4% difference on flat roof replacement is minor — you'll typically see a wider spread just from getting multiple quotes in the same city, so don't let location drive the decision.

Cheapest time for flat roof replacement in either city
Storm season pushes demand — and prices — up through summer, since shingles need warm, dry weather to bond correctly. Roofers with open winter calendars will often deal to fill a spring slot.
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 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 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 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 two things that actually protect a roofing budget are a real tear-off and a written rate for any deck repairs found along the way. The cheapest post-storm bid usually isn't the cheapest roof, long-term.
