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
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?
Roofing budgets swing on decisions most homeowners don't think to ask about — overlay vs. tear-off, shingle tier, deck condition. Our editors break down each one.
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 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
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.
A roof's real cost shows up over its lifespan, not on install day. Tear-off, a documented repair rate and a mid-tier shingle grade are what keep that lifetime cost in check.
