Cheapest time for flat roof replacement in either city
Shingles seal properly only in warm, dry conditions, which is exactly when everyone else wants a new roof too — especially right after a summer hailstorm. Lock in a late-fall or winter booking for a spring install and you skip that rush.
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 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 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
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.
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.
