How much should this gap actually matter?

Asphalt shingle roof replacement by roof size: Bangor vs Portland
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 | Bangor | Portland |
|---|---|---|
| 1,000 sq ft (10 squares) | $4,200–$7,500 | $4,400–$7,850 |
| 1,500 sq ft (15 squares) | $5,450–$10,050 | $5,700–$10,550 |
| 2,000 sq ft (20 squares) | $6,150–$12,650 | $6,450–$13,300 |
| 2,500 sq ft (25 squares) | $8,000–$14,700 | $8,400–$15,450 |
| 3,000 sq ft (30 squares) | $9,550–$17,800 | $10,050–$18,700 |
| 3,500+ sq ft (35 squares) | $11,100–$20,900 | $11,650–$21,950 |

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?
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 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
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
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.
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.
