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?
Tear-off vs. overlay, shingle tier and what's hidden under the deck decide the real number. Our editors on the trade-offs.
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 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.
Three habits keep a roof from costing more than it should: strip to the deck, choose an architectural shingle, and get the decking-repair rate on paper before the tear-off begins. Storm season tends to produce the lowest bids and the shortest-lived roofs.
