|---|---|---|

Cheapest time for asphalt shingle 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?
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 do-it-right case
Skipping the tear-off means burying whatever's failing underneath, and a second layer bakes the shingles from below until they curl early. Doing it properly means stripping to the deck, then paying for real underlayment, flashing and airflow — the work that sets how long the roof lasts, not just how it looks the first week.
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.
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.
