Asphalt shingle roof replacement by roof size: Missoula vs Portage
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 | Missoula | Portage |
|---|---|---|
| 1,000 sq ft (10 squares) | $4,000–$7,150 | $4,150–$7,400 |
| 1,500 sq ft (15 squares) | $5,200–$9,650 | $5,350–$9,950 |
| 2,000 sq ft (20 squares) | $5,900–$12,100 | $6,100–$12,500 |
| 2,500 sq ft (25 squares) | $7,650–$14,050 | $7,900–$14,550 |
| 3,000 sq ft (30 squares) | $9,150–$17,050 | $9,450–$17,600 |
| 3,500+ sq ft (35 squares) | $10,600–$20,000 | $10,950–$20,650 |

Cheapest time for asphalt shingle roof replacement in either city
Shingles seal properly only in warm, dry conditions, which is exactly when everyone else wants a new roof too — especially right after a summer hailstorm. Lock in a late-fall or winter booking for a spring install and you skip that rush.
Where does a smart roofing budget go in 2026?
The real cost of a roof comes down to three decisions: tear-off or overlay, which shingle tier, and what condition the decking is in. Our editors weigh in.
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
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.
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.
