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 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 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
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 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.
