Firestone EPDM roofing typically costs $5-$12 per sq ft installed, or about $7,500-$18,000 for a 1,500-sq-ft roof, before unusual repairs or major tear-off work. The final price depends on membrane thickness, insulation, roof access, removal needs, labor rates, and whether the job uses Firestone-branded materials or another EPDM system.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed EPDM roofing | $5 per sq ft | $7.50 per sq ft | $12 per sq ft | Typical flat or low-slope roof, standard access |
| 1,000-sq-ft roof | $5,000 | $7,500 | $12,000 | Before major deck repairs |
| 1,500-sq-ft roof | $7,500 | $11,250 | $18,000 | Common residential project size |
| EPDM membrane material | $0.80 per sq ft | $1.50 per sq ft | $2.50 per sq ft | Membrane only; thickness and order size affect pricing |
What Firestone EPDM roofing costs on a typical roof
For a straightforward installation over a sound, prepared low-slope roof, a practical budget is $5-$9 per sq ft. A more involved project with tear-off, new insulation, flashing work, or difficult access often reaches $9-$12 per sq ft or more. Contractors may quote a complete system rather than price the membrane separately.
For a 1,500-sq-ft roof, the middle-of-the-market installed estimate is roughly $11,250. That assumes a standard black EPDM system, ordinary suburban access, no extensive deck replacement, and labor rates typical of many U.S. markets. A smaller roof may cost more per square foot because mobilization, setup, and minimum charges are spread over less area.
Firestone Building Products became part of Elevate, a roofing brand under Holcim. Quotes may therefore refer to Firestone, Elevate, or a Firestone-origin EPDM product. Brand naming alone does not establish the system’s warranty, included accessories, or installation quality; the written scope should identify the membrane and compatible components.
Assumptions: 1,500 sq ft of roof area, standard black EPDM, normal access, no structural repair, and a contractor-installed system.
How membrane, labor, and tear-off shape the quote
A roofing estimate combines more than the rubber sheet. It may include surface preparation, insulation, attachment materials, flashing, edge metal, drains, disposal, and contractor overhead. Ask whether the price includes tax, permit charges, and the removal of existing roofing so separate bids can be compared on the same scope.
| Quote component | Typical rate | Cost on 1,500 sq ft | What changes the price |
|---|---|---|---|
| EPDM membrane | $0.80-$2.50 per sq ft | $1,200-$3,750 | Thickness, color, roll size, and supplier |
| Installation labor | $2-$5 per sq ft | $3,000-$7,500 | Attachment method, details, and access |
| Insulation and cover board | $1-$4 per sq ft | $1,500-$6,000 | Thickness, R-value, and number of layers |
| Flashing and edge details | $4-$12 per linear ft | $400-$1,800 | Parapets, curbs, drains, and roof perimeter |
| Removal and disposal | $1-$3 per sq ft | $1,500-$4,500 | Roof layers, material weight, and dump fees |
| Permits and inspections | $150-$1,000 total | $150-$1,000 | Local requirements and project value |
The component figures are planning ranges, not add-ons that should automatically be summed. Contractors may bundle labor and materials, and a full-roof quote can have different unit rates from a small repair. For example, a 3-person crew working 2 days at 8 hours per day represents 48 crew-hours; at $50-$90 per labor-hour, the labor value is about $2,400-$4,320 before overhead and profit.
Compare the written scope, not just the quoted cost per square foot. One bid may include insulation and old-roof disposal while another includes only membrane installation. Confirm the number of roof layers, deck repairs, flashing locations, and system attachment method.
Thickness, insulation, and roof area change EPDM pricing
Membrane thickness is a direct material variable. A common 45-mil EPDM membrane generally costs less than a 60-mil option; the thicker product can add roughly $0.20-$0.70 per sq ft for material, depending on brand, order volume, and supplier. Ask whether the contractor’s price includes the specified thickness throughout the roof or only in selected areas.
Insulation can produce a larger swing. Adding or upgrading to a thicker assembly may add $1-$4 per sq ft, with higher costs possible for multiple layers, tapered insulation, or a high-performance cover board. On a 1,500-sq-ft roof, that range represents $1,500-$6,000. Existing insulation that is wet, crushed, or out of code may need replacement rather than being covered.
Roof geometry also matters. A 2,500-sq-ft open roof often has a lower per-square-foot price than a 500-sq-ft roof with several vents, skylights, HVAC curbs, and parapet walls. Each penetration requires careful flashing and detailing. A complex roof can add hundreds to several thousand dollars compared with a clean, uninterrupted surface.
Attachment method affects both materials and labor. Fully adhered EPDM uses adhesive over the substrate, while mechanically attached and ballasted systems have different fastening, seam, and edge requirements. Wind exposure, roof structure, and manufacturer specifications limit which methods are appropriate; the lowest material price is not automatically the lowest compliant system cost.
Measure the roof surface and count every curb, drain, and parapet before comparing bids. A rough plan showing dimensions and penetrations helps identify estimates that omit detail work. Check whether the quoted area includes vertical surfaces and overhangs, which can change the billable square footage.
How much does removing old roofing add?
Removing one layer of existing roofing commonly adds $1-$3 per sq ft, including disposal, or $1,500-$4,500 on a 1,500-sq-ft roof. Multiple layers, heavy materials, restricted access, or distant disposal facilities can raise the price. Some jurisdictions limit how many layers can remain under a new roof, so confirm local code before assuming an overlay is allowed.
Deck repair is usually priced after inspection or as a unit allowance. Replacing damaged plywood may add about $75-$150 per sheet installed, while widespread deterioration can push costs much higher. A quote should state the assumed quantity of repairs and the per-sheet or per-square-foot charge for work beyond that allowance.
Old insulation and wet roofing can conceal damage until removal. Contractors may include a contingency allowance, but it should be clearly identified rather than blended into a vague lump sum. For example, an estimate might include up to four sheets of deck repair and list the rate for each additional sheet.
Delivery and access can add costs when materials must be carried manually, lifted by crane, or transported to a remote property. Crane or lift charges may range from $300-$1,500 or more, depending on equipment, rental duration, and site conditions. Disposal charges are also affected by local landfill rates and the volume of debris.
Ask for removal, disposal, and deck-repair rates as separate quote lines. This makes it easier to compare a tear-off bid with an overlay estimate and to understand which costs are confirmed versus dependent on concealed conditions.
Installation hours and crew size behind an EPDM job
A simple 1,500-sq-ft roof may take a crew of three or four about 2-4 working days, including preparation and detail work. A larger commercial roof can take longer but may move faster per square foot when the surface is open and material handling is efficient. Rain, cold weather, wind, and drying times for adhesives can interrupt the schedule.
Roofing labor rates commonly work out to $50-$90 per worker-hour when estimating the labor component, although contractors usually quote a project price rather than an hourly bill. Urban markets and areas with limited qualified crews may run above that range. Site-specific labor can also rise when workers must use fall protection, move materials by hand, or work around occupied equipment.
Schedule is not the only labor variable. Seam layout, edge termination, and transitions at walls and penetrations require careful installation. A bid that is substantially below others may assume less preparation, omit flashing details, or use a shorter scope of work. Check crew experience with EPDM systems and the manufacturer’s installation requirements.
Ask how many workdays are included and what weather delays do to the schedule. Confirm whether the crew will protect exposed insulation or roof areas if work spans multiple days, and whether cleanup and final inspection are part of the contract.
Regional labor rates shift the installed EPDM total
National price ranges hide substantial local variation. In lower-cost rural markets, a standard installation may fall near $5-$8 per sq ft, while major metro areas with higher labor, insurance, and disposal charges can reach $8-$13 per sq ft. These are approximate comparisons for similar scope, not guarantees for a particular city.
Regional weather can change the system and timing. Cold climates may require more insulation to meet energy codes, while storm-prone areas may require specific attachment and edge details. Those requirements can add $1-$4 per sq ft for insulation or system upgrades, depending on the existing assembly and local code.
Urban access can add a further 5%-15% when parking, staging, permits, or material lifting are difficult. Rural projects may instead face travel charges or a contractor minimum, particularly when the nearest EPDM installer is far away. Request a local quote that spells out these site costs.
Use local bids for the final budget and national ranges only as a starting point. Compare at least three estimates from contractors quoting the same membrane thickness, insulation plan, tear-off scope, and flashing details.
EPDM repair or replacement for a leaking roof
Small EPDM repairs can cost $300-$1,000 when a contractor can patch an accessible seam, puncture, or flashing area. Larger repairs involving several locations or wet insulation may run $1,000-$3,500. Diagnostic or service-call fees commonly range from $100-$300 and may be credited toward approved repair work.
Replacement becomes more economical when leaks are widespread, seams repeatedly fail, or the membrane has shrunk and pulled away from edges. Replacing an entire 1,500-sq-ft system may cost $7,500-$18,000 before major deck work. A repair quote should identify the suspected source, extent of damaged insulation, and whether the fix is temporary or intended as a long-term repair.
DIY patch kits may cost $20-$100, but a patch is only effective when the membrane is clean, dry, and compatible with the repair materials. Hidden moisture or a failed seam can make a surface patch short-lived. Roof access and fall risk also make DIY work unsuitable for many homes.
Pay for an inspection before authorizing a full replacement based on one visible leak. A localized defect can be less expensive to repair, but repeated leaks or widespread wet insulation may justify replacement after the roof assembly is assessed.
Ways to lower a Firestone EPDM roofing quote
Control the scope first. Request separate prices for membrane, insulation, tear-off, deck repairs, and optional upgrades. If the roof deck and insulation are sound, keeping them may reduce work, but an overlay should only be considered when code, manufacturer instructions, and the condition of the existing roof allow it.
Choose specifications based on the building’s needs rather than selecting the thinnest or thickest membrane by default. Compare 45-mil and 60-mil options, insulation R-values, and attachment methods with the contractor. Ask for the installed price difference and warranty terms for each change, not just a materials-only upgrade price.
Prepare the site where practical by clearing access routes and moving vehicles or stored items away from the work area. Coordinate roof work with other planned exterior projects when doing so reduces repeated mobilization, but do not bundle unrelated work unless the combined scope is clear and itemized.
Collect three written bids with the same roof measurements and specifications. Check that each names the membrane thickness, installation method, flashing and edge details, tear-off layers, disposal, permits, repair allowance, cleanup, and warranty. A lower quote can still be a poor value if it excludes necessary preparation or leaves uncertain charges open-ended.
The most reliable savings come from removing unnecessary scope, not skipping required flashing or preparation. Keep a contingency of about 10%-15% of the quoted project total for concealed deck or insulation damage, especially when the existing roof has not been opened for inspection.
