Editors' roundtable

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 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 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

Nail down the per-sheet decking rate in writing before anyone climbs up. Soft or rotted plywood is the most common mid-job discovery, and without an agreed number the crew names the price after they've already found the damage — turning a cheap quote into an open tab.

Our take

Insist on tear-off over overlay, get the deck-repair rate in writing before work starts, and lean toward architectural shingles. Skipping any of the three tends to cost more later than it saves now.
