Scope Notes & Exclusions6 planning notes included with this estimate
- Includes 10% panel waste for Aluminum.
- Panel gauge, finish, compatible trim, and allowance for thermal movement should match the selected system.
- Warning: The calculator does not size attic ventilation. Confirm required net free ventilating area and intake/exhaust balance before choosing vented versus solid panels.

About the Soffit Cost Calculator
Soffit covers the underside of your roof overhang and plays a critical role in attic ventilation and protecting your roof structure from moisture and pests. Whether you're replacing damaged soffit or installing new panels, our calculator estimates total cost based on your eave perimeter, overhang width, material choice, and whether you're also replacing the fascia board.
How We Calculate Soffit Cost
We calculate net soffit area as eave perimeter multiplied by overhang width in feet, then apply the selected profile's waste—10% for aluminum or vinyl and 15% for wood—to the panel purchase area. Each material has its own panels, trim/receiver system, installation labor, fascia material, and fascia labor. Replacement adds soffit removal and, when fascia is selected, a separate fascia-removal line. Net free ventilation area is intentionally not inferred from floor area or panel area.
Factors That Affect Soffit Cost
Key factors include material and finish, eave perimeter, overhang width, panel waste, compatible channels and receivers, fascia scope, replacement demolition, eave access, local labor rates, and the designed mix of vented and solid panels. Unusually high or obstructed eaves may need dedicated staging or a lift, which remains outside this calculator.
Soffit Rates Used in This Calculator
Base one-story model rates before regional adjustment. Panel and installation costs scale with soffit area; trim and fascia scale with eave perimeter.
| Profile / line | Waste | Panel material | Installation labor | Trim / linear ft |
|---|---|---|---|---|
| Vinyl | 10% | $3 – $8 / sq ft | $2.50 – $6.50 / sq ft | $0.40 – $1.25 |
| Aluminum | 10% | $4 – $12 / sq ft | $3 – $8 / sq ft | $0.50 – $1.50 |
| Wood | 15% | $6 – $16 / sq ft | $4 – $11 / sq ft | $0.75 – $2.50 |
| Replacement soffit removal | — | — | $1 – $3 / sq ft | — |
| Replacement fascia removal | — | — | — | $0.75 – $2.50 |

Two soffit replacement examples
These examples are generated from the same model as the calculator above and use national pricing before the Location adjustment.
Example 1 — 160 linear ft of 12-inch aluminum soffit. That equals 160 net sq ft; 10% waste produces 176 sq ft of panel purchase area. Replacement without fascia is $1,424–$4,112, with a $2,512 midpoint: $1,392 in panels and trim plus $1,120 in installation and removal/disposal. A new installation with no tear-off is $1,264–$3,632, with a $2,192 midpoint.
Example 2 — add aluminum fascia to the same replacement project. The modeled range becomes $2,344–$7,232 with a $4,352 midpoint. The $1,840 midpoint increase comprises $960 of fascia material, $640 of installation labor, and $240 for existing-fascia removal/disposal along the full perimeter.
Measure area before comparing per-foot quotes
Linear footage alone does not describe the amount of soffit. A 160-linear-ft home with a 12-inch overhang has about 160 sq ft of soffit; the same perimeter with a 24-inch overhang has about 320 sq ft and roughly doubles the panel-based material and labor lines. Measure each eave section and its width instead of assuming every side is identical.
Ask bidders to state both measured square footage and perimeter, then separate panels, ventilation pattern, J-channel, tear-off, fascia, access equipment, and hidden wood repair. A quote priced only per linear foot can look inexpensive because it silently assumes a narrow overhang or excludes fascia and disposal.
When soffit damage points to a larger roof problem
Soft wood, staining, peeling paint, or repeated animal entry can be a symptom rather than the whole repair. Before covering the opening, identify whether water is arriving from failed drip edge, gutter overflow, roof flashing, or condensation from blocked attic ventilation. Replacing panels without correcting the source can hide continued rafter-tail and fascia damage.
Coordinate widespread soffit work with roof and gutter inspection. The related roof-replacement and siding calculators can help frame adjacent budgets, but the contractor's written scope should identify who repairs sheathing or framing if demolition exposes decay.
Soffit Cost by Eave Perimeter
| Eave Perimeter | Low | Average | High |
|---|---|---|---|
| 80 linear ft | $712 | $1,256 | $2,056 |
| 120 linear ft | $1,068 | $1,884 | $3,084 |
| 160 linear ft | $1,424 | $2,512 | $4,112 |
| 240 linear ft | $2,136 | $3,768 | $6,168 |
| 320 linear ft | $2,848 | $5,024 | $8,224 |
| 480 linear ft | $4,272 | $7,536 | $12,336 |

Cost basis & data provenance
Scope-matchedThis calculator checks a typical 160 linear ft × 12-in aluminum soffit replacement, fascia excluded against a scope-matched benchmark of $2,000–$3,000, using Fixr roof-eaves repair guide (linear-foot unit range) (accessed 2026-07-22). Cost data is scheduled for review by 2027-01.
- Fixr — Roof Eaves Repair: $6–$20 per linear foot. Applied to 160 linear feet as a unit check; the default is full aluminum soffit replacement without fascia and includes 10% panel waste. Checked 2026-07-22.
