Roofing felt paper typically costs $15-$50 per roll, or about $0.04-$0.15 per covered square foot for the material. For a contractor to supply and install felt on an accessible roof, a common price is $0.20-$0.60 per square foot; roof size, felt weight, tear-off, and local labor rates change the total.
The estimates below cover felt underlayment, not shingles, decking repairs, or a complete roof replacement. Assumptions: standard asphalt-saturated felt, ordinary roof access, and typical U.S. pricing before unusual repairs or local taxes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 15-pound felt roll | $15 | $22 | $30 | About 400 sq ft nominal coverage |
| 30-pound felt roll | $25 | $37 | $50 | About 200 sq ft nominal coverage |
| Felt material per covered sq ft | $0.04 | $0.08 | $0.15 | Weight and roll coverage affect rate |
| Installed felt per sq ft | $0.20 | $0.35 | $0.60 | Labor and basic fasteners included |
| 1,500-sq-ft roof area | $300 | $525 | $900 | Felt installation only, before removal |
What Roofing Felt Costs for a 1,500-Square-Foot Roof
For a straightforward roof, felt material and installation often total $300-$900 on 1,500 square feet of roof area. A typical midrange budget is about $525, based on roughly $0.35 per square foot. This is a roof-surface estimate, not the home’s interior floor area; roof pitch, overhangs, and layout can make the roof larger than the house footprint.
Material-only cost is commonly $60-$225 for the same area, depending on weight, waste, and overlap. Contractors usually buy extra felt because courses overlap and roof edges, valleys, and penetrations require cuts. A simple gable roof may need less extra material than a roof with several hips, dormers, or valleys.
Roll labels may list nominal coverage, but usable coverage is lower after laps and trimming. As a rough buying estimate, 15-pound felt often covers about 350-400 square feet per roll in practical use; 30-pound felt may cover about 180-200 square feet. Confirm the product label and the roofer’s takeoff before comparing roll counts. Assumptions: roof area is measured along the roof surface, ordinary access, no deck repair, and no old underlayment removal.
How Felt, Fasteners, and Installation Shape the Quote
A felt quote is usually dominated by labor when the material is basic and the roof is easy to access. The table separates common charges for a small-to-medium residential installation. Actual proposals may combine materials and labor into one per-square-foot rate, so the line items are useful for comparison rather than a required billing format.
| Quote component | Typical rate | 1,500-sq-ft example | What changes the charge |
|---|---|---|---|
| 15-pound felt material | $0.04-$0.08 per sq ft | $60-$120 | Roll price, waste, overlap |
| 30-pound felt material | $0.08-$0.15 per sq ft | $120-$225 | Heavier product and coverage |
| Installation labor | $0.12-$0.35 per sq ft | $180-$525 | Pitch, height, layout, crew rate |
| Fasteners and small supplies | $0.01-$0.04 per sq ft | $15-$60 | Staples or cap nails, code and product needs |
| Removal and disposal, if needed | $0.05-$0.20 per sq ft | $75-$300 | Existing layers and cleanup requirements |
Labor rates commonly work out to about $50-$100 per worker-hour, though a contractor may price the task by area or as part of shingle installation. A crew may spend only a few hours laying felt on an open roof, but staging, edge work, cleanup, and coordination with shingle installation add time.
Removal is not always necessary. When felt is being installed over a stripped roof deck, its cost is part of the roof replacement workflow; when old felt must be scraped or separated, disposal and extra handling can add a distinct charge. Ask whether the quote includes underlayment removal, fasteners, cleanup, and protection from rain during the work.
Why Roof Pitch, Felt Weight, and Waste Change the Price
Roof geometry and access can change labor more than the difference between two basic felt rolls. A low-slope, single-story roof with broad uninterrupted sections is quicker to cover than a steep roof with several stories, valleys, dormers, and many roof penetrations. Higher fall risk can require extra safety setup and slower work, increasing labor charges.
Felt weight is another direct material variable. Fifteen-pound felt is generally the lower-cost option and is often selected for standard applications when allowed by the roofing system and local requirements. Thirty-pound felt costs more per roll and covers less area, but some specifications call for a heavier underlayment. The choice should match the shingle manufacturer’s instructions, roof design, and applicable code rather than price alone.
Waste also depends on roof shape. A simple roof may need roughly 5%-10% extra material for laps and trimming; a cut-up roof with hips, valleys, and dormers can require 10%-20% extra. For example, a 2,000-square-foot roof at 15% waste needs about 2,300 square feet of usable coverage, not just the measured surface area.
Local rules and product specifications may affect fastening patterns and underlayment selection. Coastal wind exposure, cold-weather installation, or a low-slope area may call for a different system or additional layers. These cases can raise the installed price beyond a basic felt estimate; a contractor should identify the specific requirement rather than simply adding an unexplained allowance. Assumptions: ordinary residential shingles and no special underlayment system beyond the quoted felt.
How Many Labor Hours Does Felt Installation Take
On an open 1,500-square-foot roof, laying felt commonly takes a small crew a few hours, while complex roof preparation can take most of a workday. Labor time depends on whether the deck is already clear, whether the crew is also installing shingles, and how many edges and penetrations need careful cutting.
A two- or three-person crew may complete the felt portion in about 3-6 labor-hours on a simple, accessible roof. A steep or multi-plane roof may require 6-12 labor-hours or more, particularly when the job includes handling multiple layers, protecting exposed decking, or coordinating around weather. These are total crew-hours, not necessarily elapsed clock time.
For an hourly comparison, two workers on a three-hour task at $50-$100 per worker-hour imply $300-$600 in labor before materials. Contractors often use production pricing instead, and the quote may include setup and cleanup. Ask whether the hourly rate applies only to felt placement or also to roof preparation and removal.
Felt is usually installed as part of a larger roofing job, so a separate minimum charge can make a tiny repair expensive per square foot. A roofer may charge $150-$400 or more to schedule a small underlayment repair, even if the exposed area is limited. The minimum reflects travel, setup, safety equipment, and the need to tie the repair into surrounding roofing.
How Roof Felt Prices Differ Across U.S. Markets
Labor and access explain most regional price differences; roll prices tend to vary less than installed rates. In lower-cost rural markets, straightforward installation may fall near $0.20-$0.35 per square foot. In many suburban markets, $0.25-$0.50 is a reasonable planning range. Dense cities or high-wage coastal areas can reach $0.40-$0.70 or more when access, parking, disposal, or safety logistics are difficult.
These ranges are directional, not fixed regional tariffs. A city contractor may have higher labor and insurance expenses, while a rural project can incur a travel or minimum-service charge. Local supply, seasonal demand, and the number of competing roofing crews also affect quotes. A remote location may pay more for delivery even if hourly labor is less expensive.
To compare quotes fairly, use the same roof-area measurement, felt weight, overlap assumptions, and work scope. One bid at $0.30 per square foot may exclude removal, while another at $0.48 may include disposal and fasteners. For a 1,500-square-foot roof, a 20% regional difference changes an installed estimate of $525 by about $105, but scope differences can be larger.
Homeowners should compare at least two or three local written estimates when the work is part of a roof replacement. The estimate should identify whether the amount is for felt alone or for all underlayment, whether the roof is measured by surface area, and whether taxes, delivery, and cleanup are included.
When 15-Pound Felt Beats 30-Pound Paper on Price
Fifteen-pound felt is usually cheaper per square foot, while 30-pound felt uses more material dollars for stronger, heavier coverage. A 15-pound roll commonly costs $15-$30 and a 30-pound roll about $25-$50. Because the heavier roll covers roughly half as much area, comparing roll prices alone can make the price gap look smaller than it is.
At practical coverage, 15-pound felt may run about $0.04-$0.08 per square foot, versus approximately $0.08-$0.15 for 30-pound felt. On 1,500 square feet, that is roughly $60-$120 compared with $120-$225 before waste. The heavier product can add about $60-$105 in material on this example, though local shelf prices and exact coverage vary.
Felt is also compared with synthetic underlayment, which often costs around $0.10-$0.30 per square foot for material. Synthetic products may cover more area per roll, weigh less, or offer installation advantages, but their installed cost and suitability depend on product specifications and roof conditions. The least expensive roll is not automatically the lowest-cost system if it requires more handling or does not meet the project requirements.
Underlayment should not be treated as a substitute for damaged decking or as a permanent roof covering. If a roof deck is soft, stained from ongoing leaks, or visibly deteriorated, repairs may be needed before felt is installed. A roofer should explain whether the quote includes only underlayment or any deck replacement and flashing work.
Three Roofing Felt Quotes for Common Roof Sizes
These examples show how area, waste, and labor produce different totals even when all three jobs use basic asphalt-saturated felt. They assume ordinary access, no deck repair, and a contractor’s installed rate that includes felt and routine fasteners. Removal, permit fees, and taxes are excluded unless stated.
| Roof scenario | Area and material | Estimated labor | Installed total |
|---|---|---|---|
| Small detached garage | 600 sq ft; 15-pound felt, about $25-$55 | 2-person crew, 2-3 hours; $200-$450 | $250-$550 |
| Simple ranch roof | 1,500 sq ft; 15-pound felt, about $60-$120 | 2-3-person crew, 3-6 hours; $300-$650 | $450-$900 |
| Cut-up two-story roof | 2,400 sq ft; 30-pound felt, about $220-$400 with waste | 3-person crew, 6-10 hours; $700-$1,300 | $1,000-$1,800 |
The garage example has a relatively high labor cost per square foot because minimum setup charges are spread over a smaller area. The cut-up roof needs more material allowance and slower installation around valleys and penetrations. These estimates are useful for checking a quote’s scale, not for replacing an on-site measurement.
When a roofer quotes a bundled roof replacement, felt may not appear as a separate line. Ask for the product name, weight, coverage, and whether the price includes installation. A bundled quote can still be compared by requesting the total scope and material specifications rather than insisting that each contractor use identical accounting categories.
Which Felt Paper Costs Can a Homeowner Control
The most reliable savings come from controlling scope and avoiding duplicate charges, not from choosing underlayment that fails the roof specification. Confirm whether felt removal is genuinely required, whether existing material is already included in a tear-off charge, and whether disposal appears twice in the proposal. Ask for the total price and a clear description of what is included.
Measure the roof surface rather than using the home’s floor area, then compare the contractor’s calculated area and waste allowance. A simple roof may need less extra felt than a roof with many cutouts. If a bid assumes 20% waste on a plain gable roof, ask for the basis; if it assumes only 5% on a roof full of valleys, ask whether that is sufficient.
Choosing 15-pound rather than 30-pound felt can reduce the material budget by roughly $60-$105 on a 1,500-square-foot example, but only when the roof design and product requirements permit it. Do not request thinner material solely to lower the quote if the specifications call for heavier felt or another underlayment. The price difference is small compared with the cost of removing and reinstalling a failed roof assembly.
Scheduling felt work with the shingle installation avoids a separate trip and can prevent a minimum-service charge. On a replacement, ask whether the roofer can price underlayment as part of the full project. If only a small section needs repair, compare a properly integrated patch with a larger replacement; patching is less expensive only when surrounding felt and shingles remain serviceable.
Get written quotes that specify felt weight, measured area, labor, removal, disposal, fasteners, and any stated exclusions. A low bid that omits protection for exposed decking or cleanup may not be cheaper after added charges. Assumptions: savings depend on local code, manufacturer instructions, roof condition, and a contractor’s minimum charge.
