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

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?
A roofing quote can hide a lot behind a single number — whether it's a true tear-off, the shingle grade, and what's under the surface. Here's how our editors sort through it.
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
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 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.
