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?
The real cost of a roof comes down to three decisions: tear-off or overlay, which shingle tier, and what condition the decking is in. Our editors weigh in.
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 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 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.
