Best time to buy

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.

Late spring to early fall (dry, 45–85°F)

Editors' roundtable

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

The surprise that wrecks a roofing budget is rot in the decking, and you rarely see it until the old shingles come off. Fix the price per replacement sheet in the contract before the crew starts, so a low bid can't quietly climb once the deck is open.

The value case

For a typical home, the architectural shingle is the default that makes sense. It outlasts 3-tab by a wide margin at a modest premium, and it spares you the cost of metal or tile that most roofs never need to justify.

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.

Our take

A roof's real cost shows up over its lifespan, not on install day. Tear-off, a documented repair rate and a mid-tier shingle grade are what keep that lifetime cost in check.
