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)
- Deck repair, underlayment grade and ventilation may or may not be in the price.
- A storm-chaser's lowball often skips flashing, ice-and-water shield or a real warranty.
- One bid is a full tear-off; another lays new shingles over the old roof — cheaper now, costlier later.
Get an apples-to-apples bid
- Ask how deck/sheathing repairs are priced if rot is found.
- Specify tear-off vs. overlay so all bids match.
- Compare the workmanship warranty, not just the material warranty.
- Verify the contractor is licensed, insured and local, with recent references.

Where does a smart roofing budget go in 2026?
Roofing budgets swing on decisions most homeowners don't think to ask about — overlay vs. tear-off, shingle tier, deck condition. Our editors break down each one.
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.
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.
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.
