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?
A roofing quote can hide a lot behind a single number — whether it's a true tear-off, the shingle grade, and what's under the surface. Here's how our editors sort through it.
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 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
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.
Judge a roofing bid on its scope, not its bottom line — a genuine tear-off, a documented per-sheet deck rate, and a mid-grade architectural shingle. Those three close the gaps that let a low storm-season number balloon over the years.
