How much should this gap actually matter?
A 15% gap is meaningful on a project this size — about $1,450. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Seattle.

Asphalt shingle roof replacement by roof size: Seattle vs Tri-Cities
Roofing is priced per 'square' (100 sq ft of roof). A roof is bigger than the home's footprint because of pitch and overhangs — a 2,000 sq ft home often has a 2,200–2,600 sq ft roof. Asphalt runs about $3–$5 per sq ft installed.
| Size | Seattle | Tri-Cities |
|---|---|---|
| 1,000 sq ft (10 squares) | $4,850–$8,650 | $4,200–$7,450 |
| 1,500 sq ft (15 squares) | $6,300–$11,650 | $5,400–$10,050 |
| 2,000 sq ft (20 squares) | $7,100–$14,600 | $6,150–$12,600 |
| 2,500 sq ft (25 squares) | $9,250–$17,000 | $8,000–$14,650 |
| 3,000 sq ft (30 squares) | $11,050–$20,600 | $9,500–$17,700 |
| 3,500+ sq ft (35 squares) | $12,850–$24,150 | $11,050–$20,800 |

What roofing pros earn in each metro
About 60% of a asphalt shingle roof replacement bill goes to labor, so wage differences between these two metros matter more than almost anything else. These are real, government-sourced (BLS OEWS) installer wages, not estimates.

Cheapest time for asphalt shingle roof replacement in either city
Why summer costs more: it's the only stretch shingles seal reliably, so every storm-damaged roof in the region is competing for the same crews. Reserve a spring slot during the slow winter season and you're not in that queue.
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 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
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 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.
Full tear-off, architectural shingles and a written deck-repair rate protect you from the two big risks — hidden rot and warranty gaps. The lowest storm-season bid is rarely the cheapest over the roof's life.
