Cheapest time for flat roof replacement in either city
Storm season pushes demand — and prices — up through summer, since shingles need warm, dry weather to bond correctly. Roofers with open winter calendars will often deal to fill a spring slot.
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 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 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
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.
Insist on tear-off over overlay, get the deck-repair rate in writing before work starts, and lean toward architectural shingles. Skipping any of the three tends to cost more later than it saves now.
