Prices for tar paper, or roofing felt, vary by roll size, weight, and installation complexity. This article presents realistic cost ranges in USD, including per-roll, per-square, and per-hour estimates to help buyers budget accurately. The main cost drivers are roof area, underlayment type, and labor rates in the local market.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Tar paper roll (15 lb felt, 36 in wide) | $0.60 | $1.20 | $1.90 | Per roll; typical coverage 100 sq ft |
| Tar paper roll (30 lb felt, 36 in wide) | $0.95 | $1.80 | $2.75 | Heavier, better tear resistance |
| Materials total (per 1,000 sq ft) | $180 | $320 | $520 | Assumes standard 15–30 lb felt |
| Labor for installation (per 10 sq ft) | $0.40 | $0.70 | $1.10 | Roofer wage range varies by region |
| Labor total (per 1,000 sq ft) | $40 | $70 | $110 | Includes basic fastening and overlaps |
| Disposal/cleanup | $0 | $15 | $50 | Per job; depends on debris |
Tar Paper Cost By Roll Size And Weight
Most buyers pay per roll when estimating tar paper cost. Typical options include 15 lb and 30 lb felt with 36-inch widths. A 100-square-foot section usually needs about one roll of 15 lb felt, while 30 lb felt may reduce roll count but increases material cost per square foot. For a standard 1,000 sq ft roof, plan on 10–12 rolls of 30 lb felt to ensure overlaps and proper nailing zones. Assumptions: standard attic access, typical roofing nails, no unusual pitch.
Per-Unit Pricing For Roofing Felt Usage
Pricing by unit helps when comparing bids across contractors. Tar paper commonly costs $0.60–$2.75 per roll depending on weight and brand, with coverage often expressed as 100 sq ft per 36-inch roll. Per-square calculations show material costs around $1.80–$5.20 per 100 sq ft for heavier products. Assumptions: mid-grade underlayment, typical residential shingle roof.
Labor Costs And Installation Time
Labor for laying tar paper typically ranges from $0.40 to $1.10 per square foot, depending on roof pitch, access, and weather. For a 1,000 sq ft roof, expect labor costs around $40–$110 if the crew uses standard methods. Weather delays, ladder setup, and disposal time can push costs higher.
Cost Drivers By Roof Size And Pitch
Roof area and pitch are major drivers. A steeper roof increases crew time and safety measures, raising costs. For a low-slope 1,000 sq ft roof, material plus labor might run $1,000–$2,000, while a 2,000 sq ft roof could be $2,000–$4,200. Assumptions: single-story home, standard access.
Regional Variations In Tar Paper Pricing
Prices vary by region due to labor markets and supply. The West and Northeast often see higher labor rates than the South or Midwest, adding roughly 10–25% to overall costs in coastal areas. Assumptions: typical suburban markets, standard material brands.
Material Substitutes And Tradeoffs
In some cases, builders may substitute lighter felt or synthetic underlayment. Per-roll costs shift accordingly: 15 lb felt is cheaper but provides less tear resistance than 30 lb felt. Total project cost can change by 20–40% when switching material grades. Assumptions: single-ply roofing system, standard overlaps.
Quote Structure: What A Typical Tar Paper Job Includes
A standard quote breaks down into materials, labor, disposal, and optional permits. The following table illustrates a representative quote for a 1,000 sq ft roof using 30 lb felt.
| Cost Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (tar paper 30 lb, 36 in) | $180 | $320 | $520 | Assumes 1,000 sq ft coverage |
| Labor | $40 | $70 | $110 | Two-person crew, 2–3 hours |
| Disposal | $0 | $20 | $50 | Refuse and nails |
| Subtotal | $220 | $410 | $680 | |
| Permits/Inspections | $0 | $50 | $150 | Depends on locality |
| Total Project Cost | $220 | $460 | $830 | Includes baseline materials and labor |
Strategies To Lower Tar Paper Costs Without Sacrificing Quality
Controlling scope is the most reliable way to reduce price. Consider bundling underlayment with other roof work, choosing standard weight felt, and avoiding premium brands on simple roofs. Scheduling during dry seasons helps keep labor rates closer to average. Compare multiple bids and verify wind rating compatibility with local code.
Frequently Needed Details By Project Type
Residential roofs commonly require 100–400 linear feet of roll length per section depending on roof geometry. For multi-story homes, labor escalation can add 15–25% due to safety measures. Assumptions: asphalt shingle system, standard eave overhangs.
Regional Price Range Snapshot
In urban markets, tar paper costs trend higher due to logistics and labor. Rural areas may show lower material costs but longer job durations. A typical 1,000 sq ft job ranges from $1,000 to $2,500 depending on region and roof complexity. Always cross-check local prices before committing.
