| Item | Low | Average | High |
|---|---|---|---|
| Minor Leak Repair Patching a single leak point, replacing a few shingles, resealing flashing around a vent or chimney. | $200 | $550 | $1,200 |
| Moderate Repair (One Section) Replacing damaged shingles across one slope, fixing sagging decking in a limited area, or addressing storm damage to 100–200 sq ft. | $800 | $1,800 | $3,500 |

Minor Leak Repair
Patching a single leak point, replacing a few shingles, resealing flashing around a vent or chimney.
Moderate Repair (One Section)
Replacing damaged shingles across one slope, fixing sagging decking in a limited area, or addressing storm damage to 100–200 sq ft.
Major Structural Repair
Replacing rotted decking, repairing trusses, or fixing widespread water damage across multiple sections.
Full Asphalt Shingle Replacement
Tear-off of existing roof and full re-roof with architectural asphalt shingles on a 1,500–2,500 sq ft home.
Full Metal Roof Replacement
Standing-seam or corrugated metal over a 1,500–2,500 sq ft home. Longer lifespan but higher upfront cost.
Roof Inspection
Professional inspection to assess whether repair or replacement is needed. Some contractors offer free inspections with a signed contract.
📊 Factors That Impact Cost
Roof Age
High ImpactAsphalt shingle roofs last 20–30 years. If yours is past 20 and needs repair, replacement usually makes more financial sense than repeated patches.
Damage Extent
High ImpactDamage affecting more than 30% of the roof surface, or damage to the decking and underlayment, generally tips the math toward replacement.
Roof Size and Pitch
High ImpactSteeper roofs cost 20–40% more for labor. A 2,500 sq ft roof costs roughly 60% more than a 1,500 sq ft roof for the same material.
Material Choice
High ImpactThree-tab asphalt is cheapest ($3.50–$5.50/sq ft installed). Architectural shingles run $4.50–$8/sq ft. Metal starts at $7/sq ft and goes up from there.
Number of Existing Layers
Medium ImpactMost codes allow two layers of asphalt shingles. If you already have two layers, a tear-off is required before re-roofing, adding $1,000–$3,000.
Geographic Location
Medium ImpactLabor rates vary 30–50% between regions. Coastal and hurricane-prone areas may require upgraded materials and fastening methods that add 10–20% to cost.
💡 Money-Saving Tips
Get 3 quotes and compare scope, not just price
The cheapest bid often excludes decking repair or proper flashing replacement. Compare line-item scope across at least three contractors to avoid surprise change orders.
Schedule in late fall or winter
Roofers are busiest from late spring through early fall. Booking in the off-season (November–February in most markets) can knock 10–15% off labor costs.
Repair early before damage spreads
A $500 flashing repair today prevents a $5,000 decking-and-insulation job next year. Address leaks within days, not months.
Check your homeowners insurance
Storm and hail damage are covered by most policies. File a claim before starting work — adjusters need to see the damage. Coverage typically handles replacement minus your deductible.
Overlay instead of tear-off when code allows
If you have only one existing layer and the decking is sound, installing new shingles over the old ones saves $1,000–$3,000 in tear-off and disposal costs.
✨ When to Splurge
Upgrade to architectural shingles
They last 25–30 years vs. 15–20 for three-tab, resist wind better, and improve curb appeal. If you're already paying for labor and tear-off, the material upgrade cost is marginal relative to the lifespan gain.
Add a ridge vent system
Proper attic ventilation extends roof life by reducing heat and moisture buildup. Adding ridge and soffit vents during re-roofing is far cheaper than retrofitting later.
Install ice-and-water shield in valleys and eaves
In freeze-thaw climates, self-adhering membrane under shingles at vulnerable points prevents the most common source of interior water damage. Many contractors skip it unless asked.
