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?
Roofing budgets swing on decisions most homeowners don't think to ask about — overlay vs. tear-off, shingle tier, deck condition. Our editors break down each one.
The value case
Architectural shingles sit between bargain 3-tab and premium metal or tile, and for most houses that middle ground is exactly right. They carry longer wind and wear ratings than 3-tab for a small step up in price, without the four-figure jump metal or tile demands.
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
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.
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.
