Tyvek roofing underlayment prices typically run $100-$250 per roll, or about $0.10-$0.35 per covered square foot, depending on product and coverage. A roofer’s installed charge is often $0.30-$0.90 per square foot when underlayment is part of a roof replacement; roof size, roof pitch, tear-off, and local labor rates affect the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Tyvek synthetic underlayment roll | $100 | $165 | $250 | Commonly covers about 1,000-1,200 sq ft before overlap and waste |
| Material per covered sq ft | $0.10 | $0.18 | $0.35 | Product type and roll coverage vary |
| Installed underlayment | $0.30/sq ft | $0.55/sq ft | $0.90/sq ft | Usually priced within a full roofing job |
| 2,000-sq-ft roof area | $600 | $1,100 | $1,800 | Underlayment work only; excludes new shingles |
What Tyvek roof underlayment costs by roll and roof size
Tyvek-branded roofing underlayment is generally sold as synthetic roof underlayment, including products in the Tyvek Protec line. A standard roll may cost approximately $100-$250, with the exact price changing by product, roll dimensions, seller, and availability. Check the label for stated coverage rather than comparing roll prices alone.
At roughly $0.10-$0.35 per square foot of nominal coverage, material for a 1,000-sq-ft roof plane may cost $100-$350 before overlap, waste, fasteners, and delivery. A 2,000-sq-ft roof may require two or more rolls, depending on coverage and layout. Roof area is not always the same as a home’s floor area.
For a typical 2,000-sq-ft roof, budget about $200-$700 for Tyvek underlayment material and around $600-$1,800 for installed underlayment work. Installed totals assume ordinary access and a standard asphalt-shingle reroof; difficult access, steep slopes, and deck repairs can raise the quote.
Assumptions: U.S. retail material pricing, standard residential roof, normal access, and no major deck replacement.
How underlayment materials, labor, and removal shape the quote
A roofing estimate may combine underlayment with other roofing work or list it as a separate line item. The following ranges show typical budget components for a 2,000-sq-ft roof area. They are not fixed national rates; scope and local contractor pricing make a substantial difference.
| Quote component | Low | Average | High |
|---|---|---|---|
| Tyvek underlayment material | $200 | $400 | $700 |
| Installation labor | $300 | $700 | $1,200 |
| Fasteners and accessories | $40 | $100 | $220 |
| Old underlayment removal and disposal | $100 | $300 | $700 |
| Delivery, overhead, and small-job allowance | $50 | $200 | $500 |
Labor may be included in a complete roof installation price instead of shown separately. A standalone underlayment job can cost more per square foot because mobilization, fall protection, and setup still take time on a small roof. Ask whether the quote includes removal, disposal, fasteners, and protection of exposed decking.
Materials are only one portion of the bill; labor and access conditions can equal or exceed the product cost. A quote that seems unusually low may exclude tear-off, accessory installation, or labor to correct damaged decking.
Illustrative labor calculation: 8-16 crew-hours at a combined $50-$90 per worker-hour can represent roughly $400-$1,440 in labor, before overhead and other work.
Roof area, roll coverage, and pitch change material needs
Measure the actual roof surface, not just the home’s footprint. A simple roof with a 1,500-sq-ft horizontal footprint can have more than 1,500 square feet of sloped surface. Dormers, valleys, hips, and cutouts also affect how efficiently a crew can use each roll.
Rolls commonly advertise coverage near 1,000-1,200 square feet, but that is nominal coverage. Courses overlap at seams, and more material is needed at edges and around penetrations. For estimating, a straightforward roof may need 5%-10% extra; complex layouts can require 10%-15% or more.
Roof pitch changes both surface area and installation effort. A low-slope roof may need a different underlayment system or additional waterproofing, while a steep slope above 8:12 can slow handling and fastening. The right product and installation method depend on the roofing material, manufacturer instructions, and local code.
For example, 2,000 square feet of roof at 10% waste requires about 2,200 square feet of coverage. At a nominal 1,000 square feet per roll, that means at least three rolls, not two. Confirm usable coverage and overlap details on the product packaging.
Product performance and weight also influence price. A basic synthetic sheet and a reinforced or higher-performance version may have different roll prices and installation requirements. Ice-and-water protection is a separate membrane in many estimates, not simply an upgrade to the entire Tyvek field underlayment.
How long roofers need to install synthetic underlayment
On an uncomplicated 1,500-2,500-sq-ft roof with exposed, sound decking, a roofing crew may install underlayment in part of a workday. A full reroof schedule includes tear-off, inspection, repairs, and shingle installation, so underlayment is usually one phase rather than a separate day of work.
Labor rates vary by market and contractor. For estimating, roof labor may work out to roughly $40-$90 per worker-hour, but a customer’s quote also covers supervision, insurance, safety equipment, overhead, and profit. Crew size, steepness, weather, and how much edge or valley detail is present can matter more than the posted hourly rate.
Ask whether the contractor plans to dry-in the roof the same day. If weather interrupts the job, temporary protection and return visits can add cost. A schedule that exposes a large area of decking overnight may require extra precautions, particularly when rain is forecast.
A small standalone job may carry a minimum charge even when the roof uses only one roll. For an underlayment-only repair, request a written scope specifying the area to be covered, removal, fastening, and temporary weather protection.
Regional labor rates and delivery can shift Tyvek prices
Material prices are relatively comparable across many U.S. markets, but freight, retailer availability, and local competition affect the final amount. Labor and disposal charges tend to create larger regional differences. Urban markets with high wages or limited parking can cost more than rural markets where crews have lower overhead, though rural travel and delivery may offset some savings.
As a planning adjustment, a high-cost coastal or major metropolitan market may quote 10%-25% above a national midrange for labor-heavy work. A lower-cost area may come in 5%-15% below it. These are budgeting comparisons, not guaranteed regional price lists; a steep or complex roof can outweigh location.
Cold-weather regions may use additional ice-barrier membrane at eaves, valleys, or other code-required locations. That can add approximately $1.00-$2.50 per square foot of membrane-covered area for material and installation, depending on the product and labor. It is generally priced separately from standard synthetic underlayment.
Compare local quotes using the same roof area and product specification. A low material price from a distant supplier may not save money once delivery, minimum orders, and the contractor’s handling charge are included.
Removal, deck repairs, and waterproofing add-ons to check
Replacing old underlayment usually happens during a shingle replacement, when the roof is already open. Removing old layers and disposing of them may add around $0.05-$0.25 per square foot, or roughly $100-$500 for a 2,000-sq-ft roof. Multiple shingle layers, difficult disposal access, and local landfill fees can push charges higher.
Deck repair is often priced separately because damage cannot be confirmed until roofing materials are removed. Replacing a small area of plywood may add about $75-$150 per sheet installed, with higher charges possible for specialty decking or extensive labor. The estimate should state the per-sheet rate and whether contractor approval is required before repairs beyond an allowance.
Ice-and-water membrane, drip edge, flashing, and ridge details may appear beside the underlayment line. Eave membrane can cost roughly $1.00-$2.50 per square foot installed on the covered strip; flashing or edge-metal work is commonly priced by location or linear foot. These items serve different functions and should not be treated as duplicate Tyvek charges without checking the scope.
Separate required waterproofing from optional upgrades before comparing totals. Ask whether the roofer is replacing only the field underlayment or also covering valleys, eaves, penetrations, and transitions.
Tyvek underlayment compared with felt and other synthetics
Traditional asphalt-saturated felt can cost about $0.05-$0.15 per square foot for material, while common synthetic underlayments may run $0.08-$0.25 per square foot. Tyvek-branded products can be around $0.10-$0.35 per square foot, depending on roll coverage and product grade. Installed differences may be smaller than material differences when labor is already included in a reroof.
Felt can be a lower-cost choice, but it is heavier to handle and may wrinkle or tear when wet. Synthetic sheets are often lighter and more tear-resistant, but performance varies by product and installation. Compare the specific product’s warranty, exposure limit, slip resistance, approved roof coverings, and manufacturer instructions rather than assuming all synthetic rolls are interchangeable.
Tyvek HomeWrap is a weather-resistive barrier for walls, not a substitute for a roof-rated underlayment. A roll’s brand name alone does not establish that it is suitable for roofing. Use a product specifically labeled and approved for the roof assembly and follow local code and roof-covering requirements.
The cheapest roll is not necessarily the cheapest installed system. If a roofer charges the same labor for either product, calculate the material difference across the actual covered area, then compare the specified performance and warranty.
Reduce the underlayment bill by controlling the roof scope
Bundle underlayment with a planned reroof when practical. A separate mobilization for a small patch can have a higher per-square-foot charge than replacing underlayment while the shingles are already removed. If only a limited leak area is affected, however, a targeted repair may cost less than replacing a sound roof covering; have the damaged area inspected before expanding the scope.
Request itemized estimates from at least two or three licensed, insured roofers. Each quote should identify the product, roll coverage, roof area, waste allowance, removal, accessories, deck-repair rate, and disposal. Comparable details reveal whether a lower total reflects a genuine price difference or missing work.
Choose a product that meets the roof system’s requirements rather than paying for features the job does not need. Do not substitute a wall wrap, omit required membrane, or reduce overlap to save rolls. Ask the contractor to explain any premium product recommendation in terms of the roof slope, exposure, climate, warranty, or code requirement.
Accurate measurements and a defined repair allowance prevent surprise charges. Confirm whether the quote is based on roof surface area, whether taxes and delivery are included, and how the contractor will price concealed decking damage before work begins.
