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 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.
Full tear-off, architectural shingles and a written deck-repair rate protect you from the two big risks — hidden rot and warranty gaps. The lowest storm-season bid is rarely the cheapest over the roof's life.
