How Much Does It Cost to Refelt a Roof
The cost to refelt a roof depends on roof size, the type of felt chosen, local labor rates, and the complexity of the job. Refelting (installing new roofing felt beneath shingles or other roof coverings) protects the structure from moisture and extends the life of the roof. Homeowners should expect both material and labor to factor into the final price, with extra costs arising from steep pitches, multiple layers, or difficult roof access.
What Refelting Entails And Why Costs Vary
Refelting involves removing the old underlayment, inspecting the roof deck, and laying down a fresh layer of roofing felt or underlayment before installing shingles or other surfacing. The process helps prevent leaks, improves insulation, and provides a secondary barrier against moisture. Costs vary because felt materials differ in price and performance, deck condition affects labor time, and roof complexity (slope, gaps, vents, chimneys) changes installation difficulty.
Factors Influencing Roof Refelting Costs
- Roof Size: Cost scales with square footage. Larger homes translate to more material and longer labor hours.
- Material Type: Standard asphalt felt is less expensive than specialty underlayments (synthetic, self-adhering, or rubberized products) which offer higher durability.
- Deck Condition: If the roof deck shows rot or damage, repair costs add to the project and may extend timelines.
- Roof Pitch and Access: Steep or hard-to-reach roofs require more safety measures and time, raising labor costs.
- Geographic Location: Labor rates and material availability vary by region, influencing final prices.
- Waste and Disposal: Old underlayment removal generates waste; disposal fees affect total cost.
- Permits and Inspections: Some projects require permits or final inspections, adding administrative costs.
Typical Cost Ranges And Examples
Costs combine material and labor. The following ranges reflect common scenarios for residential refelting projects in the United States. Actual bids may differ based on local conditions and chosen materials.
| Item | Low Range (per sq ft) | Mid Range (per sq ft) | High Range (per sq ft) |
|---|---|---|---|
| Materials (standard asphalt felt) | $0.50 | $0.90 | $1.50 |
| Labor (installation) | $1.50 | $2.50 | $3.50 |
| Total Installed (materials + labor) | $2.00 | $3.40 | $5.00 |
Example estimates for common roof sizes:
- 1,000 sq ft roof: roughly $2,000–$5,000
- 1,500 sq ft roof: roughly $3,000–$7,500
- 2,000 sq ft roof: roughly $4,000–$10,000
Materials And Labor Choices
The choice of underlayment materially impacts both price and performance. Common options include:
- Standard Asphalt Felt: Most budget-friendly; provides basic moisture protection.
- Synthetic Underlayment: Lighter, more durable, and resistant to tearing; higher cost but longer life.
- Self-Adhering or Rubberized Underlayment: Excellent moisture barrier; best for cold climates or areas with ice dam risks; highest material cost.
Labor can vary based on crew efficiency, safety requirements, and deck assessment. In some markets, licensed roofers include removal of old felt, disposal, and deck repair in a single bid. In others, removal or repairs might be itemized separately, affecting overall price.
Additional Considerations: Permits, Size, Access, And Ventilation
- Permits: Not always required, but some municipalities mandate building permits for extensive roof work. Permit costs can range from $100 to $500 or more depending on locality.
- Roof Size Accuracy: An accurate measurement prevents overbilling for materials and ensures proper coverage.
- Access And Safety: If equipment needs special access or traffic control, expect additional labor time and equipment costs.
- Ventilation And Penetrations: Proper flashing around vents, chimneys, and skylights requires precision; missteps here can lead to leaks and future costs.
How To Get Accurate Quotes
To secure reliable pricing, homeowners should gather several bids and verify each contractor’s qualifications. Key steps include:
- Request a written estimate that itemizes materials, labor, disposal, permits, and any warranties.
- Ask about the underlayment brand and thickness to compare apples-to-apples across bids.
- Inspect references and request photos of previous refelting projects.
- Ensure the contractor will perform a deck inspection for rot or damage and provide repair estimates if needed.
- Confirm timeline, payment schedule, and warranty coverage for both materials and workmanship.
Tip: When comparing bids, prioritize long-term performance and reliability over the lowest price. A cheaper option may lead to premature leaks or deck damage, increasing costs down the line.
Maintenance And Longevity Post-Refelting
Quality underlayment installation can extend roof life by protecting against moisture intrusion. Regular inspections after severe weather, cleaning of gutters to prevent water backing up at eaves, and prompt repair of any damaged flashing are essential for maximizing the investment. If a roof is nearing the end of its life, replacing the shingles may be more cost-effective than continuing to refelt at short intervals.
