The verdict

Is the price difference a dealbreaker?

A 7% 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.

Best time to buy

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.

Best window
Late spring to early fall (dry, 45–85°F)
Avoid
Mid-winter and the post-storm rush

Editors' roundtable

Where does a smart roofing budget go in 2026?

The real cost of a roof comes down to three decisions: tear-off or overlay, which shingle tier, and what condition the decking is in. Our editors weigh in.

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.

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.

Our take

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.
