Best time to buy

Cheapest time for flat roof replacement in either city

The material dictates the season (shingles need warmth to seal), but the price is set by demand, and demand spikes after every regional hailstorm. Booking your spot in the quiet winter months for spring work avoids that spike.

Best window
Late spring to early fall (dry, 45–85°F)
Avoid
Mid-winter and the post-storm rush

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

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.

Our take

Full tear-off, architectural shingles and a written deck-repair rate protect you from the two big risks — hidden rot and warranty gaps. The lowest storm-season bid is rarely the cheapest over the roof's life.
