Why asphalt shingle roof replacement quotes vary — and how to compare them fairly
Price differences on an identical job trace back to the assumptions each contractor made; understand those and the 'expensive' bid often turns out fair.
Why a quote looks high (or low)
- Deck repair, underlayment grade and ventilation may or may not be in the price.
- One bid is a full tear-off; another lays new shingles over the old roof — cheaper now, costlier later.
- Shingle tier (3-tab vs. architectural vs. premium) changes both material and labor.
Get an apples-to-apples bid
- Compare the workmanship warranty, not just the material warranty.
- Specify tear-off vs. overlay so all bids match.
- Verify the contractor is licensed, insured and local, with recent references.
- Ask how deck/sheathing repairs are priced if rot is found.

- 1Is a full tear-off included, or are you laying over the existing roof?
- 2How will you handle deck repairs or rotten sheathing found after tear-off, and at what rate?
- 3What underlayment, ice-and-water shield, and ventilation are included?
- 4Are you licensed and insured here, and can you share recent local references?
- 5What's the workmanship warranty, and how does it interact with the material warranty?

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
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
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 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.
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.
