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)
- Shingle tier (3-tab vs. architectural vs. premium) changes both material and labor.
- 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.
Get an apples-to-apples bid
- Compare the workmanship warranty, not just the material warranty.
- Confirm underlayment, ice-and-water shield, flashing and ventilation are included.
- Verify the contractor is licensed, insured and local, with recent references.
- Specify tear-off vs. overlay so all bids match.

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
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
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 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.
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.
