Why asphalt shingle roof replacement quotes vary — and how to compare them fairly
When two quotes for one project diverge by thousands, the cause is usually what each one includes, not markup — here's how to read the difference.
Why a quote looks high (or low)
- One bid is a full tear-off; another lays new shingles over the old roof — cheaper now, costlier later.
- A storm-chaser's lowball often skips flashing, ice-and-water shield or a real warranty.
- Shingle tier (3-tab vs. architectural vs. premium) changes both material and labor.
Get an apples-to-apples bid
- Verify the contractor is licensed, insured and local, with recent references.
- Confirm underlayment, ice-and-water shield, flashing and ventilation are included.
- Ask how deck/sheathing repairs are priced if rot is found.
- Compare the workmanship warranty, not just the material warranty.

Where does a smart roofing budget go in 2026?
The real cost of a roof comes down to three decisions: tear-off or overlay, which shingle tier, and what condition the decking is in. Our editors weigh in.
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.
The do-it-right case
Skipping the tear-off means burying whatever's failing underneath, and a second layer bakes the shingles from below until they curl early. Doing it properly means stripping to the deck, then paying for real underlayment, flashing and airflow — the work that sets how long the roof lasts, not just how it looks the first week.
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.
Judge a roofing bid on its scope, not its bottom line — a genuine tear-off, a documented per-sheet deck rate, and a mid-grade architectural shingle. Those three close the gaps that let a low storm-season number balloon over the years.
