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.
Three habits keep a roof from costing more than it should: strip to the deck, choose an architectural shingle, and get the decking-repair rate on paper before the tear-off begins. Storm season tends to produce the lowest bids and the shortest-lived roofs.
