What roofing pros earn in each metro

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?
Tear-off vs. overlay, shingle tier and what's hidden under the deck decide the real number. Our editors on the trade-offs.
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 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.
The two things that actually protect a roofing budget are a real tear-off and a written rate for any deck repairs found along the way. The cheapest post-storm bid usually isn't the cheapest roof, long-term.
