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?
Two roofs of the same square footage can price hundreds apart because of something you can't see from the ground — the deck under the old shingles. Add the tear-off-versus-overlay call and the shingle grade, and you have the decisions that actually move the number.
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 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 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.
