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 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.
Whatever the headline bid says, the roof that lasts is the one installed on a bare, sound deck with the repair price fixed in advance. Overlays and open-ended decking charges are where a cheap quote turns expensive down the line.
