Roofers are slammed the moment warm weather returns, especially after storms. Get on their books in the off-season for a spring job and you're negotiating with an empty calendar, not a waiting list.
Why asphalt shingle roof replacement quotes vary — and how to compare them fairly
One bid high, one low, same house? The variable is scope. Here's what pushes the figure up or down and how to get quotes you can actually compare.
Why a quote looks high (or low)
- Shingle tier (3-tab vs. architectural vs. premium) changes both material and labor.
- 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
- Compare the workmanship warranty, not just the material warranty.
- Ask how deck/sheathing repairs are priced if rot is found.
- Verify the contractor is licensed, insured and local, with recent references.
- Confirm underlayment, ice-and-water shield, flashing and ventilation are included.

Do you need a permit? For this work in Seattle, yes — a Roofing permit at roughly $325, and the estimate above already carries it.
What affects asphalt shingle roof replacement cost the most?
Here's the short version: replacing an asphalt shingle roof — the most common residential roofing material. The biggest drivers are equipment/material grade, the size and complexity of your home, local labor rates, and your climate zone (mixed).
Where does a smart roofing budget go in 2026?
Two roofs of the same square footage can price hundreds apart because of something you can't see from the ground — the deck under the old shingles. Add the tear-off-versus-overlay call and the shingle grade, and you have the decisions that actually move the number.
The do-it-right case
A full tear-off lets the crew replace underlayment, flashing and ventilation while the deck is exposed — the layers that actually keep water out. Covering old shingles with new ones costs less on install day, but the trapped heat shortens shingle life, and many manufacturers won't honor a warranty on an overlay.
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 risk case
The surprise that wrecks a roofing budget is rot in the decking, and you rarely see it until the old shingles come off. Fix the price per replacement sheet in the contract before the crew starts, so a low bid can't quietly climb once the deck is open.
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.
