Asphalt shingle roof replacement by roof size: Missoula vs Somerville
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 | Somerville |
|---|---|---|
| 1,000 sq ft (10 squares) | $4,000–$7,150 | $4,850–$8,700 |

Cheapest time for asphalt shingle roof replacement in either city
Shingles need warm, dry weather to seal, and demand peaks after summer storms. Booking in the slow late-fall/winter window for a spring install often earns you off-season pricing.
Where does a smart roofing budget go in 2026?
Before you compare roofing bids, know that the biggest variables are hidden: whether the crew tears off or lays over, what grade of shingle goes down, and what the decking looks like once it's exposed. Each one can shift the total well past the advertised price.
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.
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
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.
Whatever the headline bid says, the roof that lasts is the one installed on a bare, sound deck with the repair price fixed in advance. Overlays and open-ended decking charges are where a cheap quote turns expensive down the line.
