How much should this gap actually matter?

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?
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
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.
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.
Insist on tear-off over overlay, get the deck-repair rate in writing before work starts, and lean toward architectural shingles. Skipping any of the three tends to cost more later than it saves now.
