Is the price difference a dealbreaker?
That 1% gap is small — for metal roof installation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

Cheapest time for metal roof installation 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?
Before you compare roofing bids, know that the biggest variables are hidden: whether the crew tears off or lays over, what grade of shingle goes down, and what the decking looks like once it's exposed. Each one can shift the total well past the advertised price.
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
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.
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.
