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
Roofers are slammed the moment warm weather returns, especially after storms. Get on their books in the off-season for a spring job and you're negotiating with an empty calendar, not a waiting list.
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 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.
The value case
Architectural shingles sit between bargain 3-tab and premium metal or tile, and for most houses that middle ground is exactly right. They carry longer wind and wear ratings than 3-tab for a small step up in price, without the four-figure jump metal or tile demands.
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.
Judge a roofing bid on its scope, not its bottom line — a genuine tear-off, a documented per-sheet deck rate, and a mid-grade architectural shingle. Those three close the gaps that let a low storm-season number balloon over the years.
