Asphalt shingle roof replacement by roof size: Decatur vs Missoula
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 | Decatur | Missoula |
|---|---|---|
| 1,000 sq ft (10 squares) | $3,950–$7,050 | $4,000–$7,150 |

Cheapest time for asphalt shingle roof replacement in either city
The material dictates the season (shingles need warmth to seal), but the price is set by demand, and demand spikes after every regional hailstorm. Booking your spot in the quiet winter months for spring work avoids that spike.
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
Nail down the per-sheet decking rate in writing before anyone climbs up. Soft or rotted plywood is the most common mid-job discovery, and without an agreed number the crew names the price after they've already found the damage — turning a cheap quote into an open tab.
The do-it-right case
Skipping the tear-off means burying whatever's failing underneath, and a second layer bakes the shingles from below until they curl early. Doing it properly means stripping to the deck, then paying for real underlayment, flashing and airflow — the work that sets how long the roof lasts, not just how it looks the first week.
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.
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.
