Is the price difference a dealbreaker?
A 3% 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?
Before you compare roofing bids, know that the biggest variables are hidden: whether the crew tears off or lays over, what grade of shingle goes down, and what the decking looks like once it's exposed. Each one can shift the total well past the advertised price.
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.
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.
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.
