Cheapest time for flat roof replacement in either city
Roofers are slammed the moment warm weather returns, especially after storms. Get on their books in the off-season for a spring job and you're negotiating with an empty calendar, not a waiting list.
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 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.
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.
