Cheapest time for flat roof replacement in either city
Shingles need warm, dry weather to seal, and demand peaks after summer storms. Booking in the slow late-fall/winter window for a spring install often earns you off-season pricing.
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
Nail down the per-sheet decking rate in writing before anyone climbs up. Soft or rotted plywood is the most common mid-job discovery, and without an agreed number the crew names the price after they've already found the damage — turning a cheap quote into an open tab.
The do-it-right case
A full tear-off lets the crew replace underlayment, flashing and ventilation while the deck is exposed — the layers that actually keep water out. Covering old shingles with new ones costs less on install day, but the trapped heat shortens shingle life, and many manufacturers won't honor a warranty on an overlay.
Whatever the headline bid says, the roof that lasts is the one installed on a bare, sound deck with the repair price fixed in advance. Overlays and open-ended decking charges are where a cheap quote turns expensive down the line.
