Is the price difference a dealbreaker?

Cheapest time for flat roof replacement in either city
Shingles seal properly only in warm, dry conditions, which is exactly when everyone else wants a new roof too — especially right after a summer hailstorm. Lock in a late-fall or winter booking for a spring install and you skip that rush.
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 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.
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.
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.
