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 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
Nail down the per-sheet decking rate in writing before anyone climbs up. Soft or rotted plywood is the most common mid-job discovery, and without an agreed number the crew names the price after they've already found the damage — turning a cheap quote into an open tab.
The two things that actually protect a roofing budget are a real tear-off and a written rate for any deck repairs found along the way. The cheapest post-storm bid usually isn't the cheapest roof, long-term.
