How Much Does Firestone RubberGard EPDM 60 mil Cost? (2026 Pricing & Specs)
Published: 2026-06-16
Firestone RubberGard EPDM 60 mil is the most proven single-ply roofing membrane in commercial roofing history — over 500,000 installations worldwide since 1980. EPDM (ethylene propylene diene monomer) is a synthetic rubber that remains the gold standard for durability and longevity. Its 300% elongation accommodates extreme thermal cycling and building movement that would tear less flexible membranes. The 60 mil thickness is standard specification for fully-adhered and mechanically-attached systems; 90 mil is specified for ballasted systems. Unlike TPO and PVC, EPDM is not reflective (black EPDM has a solar reflectance of 0.06), making it less suitable for buildings where energy code compliance requires a cool roof. However, white-on-black EPDM and Firestone's EcoWhite TPO cap sheet provide reflective options.
Installation Requirements
Fully-adhered RubberGard uses Firestone bonding adhesive applied to both the substrate and the membrane back. Seams are sealed with Firestone QuickSeam splice tape (no hot-air welding required — a key advantage for cold-weather installation). Ballasted systems require 10-15 lbs/sq ft of river stone ballast over a separation layer. Installed cost: $5.00-7.50/sq ft (ballasted), $6.50-9.50/sq ft (fully-adhered).
EPDM Membranes Cost by City

| San Antonio TX | $3.75-6.25/sq ft |
| Houston TX | $4.25-7.00/sq ft |
| Chicago IL | $4.25-6.75/sq ft |
| Phoenix AZ | $3.75-6.00/sq ft |
| Denver CO | $4.25-6.75/sq ft |
| Atlanta GA | $3.75-6.25/sq ft |
Costs include materials + labor for commercial installation. Prices vary by building size, access, and local labor rates.
🛡️ Roof Insurance Claim Process (Step-by-Step)
- Document the Damage — Take photos/video of all damage from multiple angles before any tarps or temporary repairs. Include close-ups of impact marks, granule loss, and membrane punctures.
- Prevent Further Damage — Install emergency tarp or temporary seal. Most policies require you to mitigate further damage. Keep receipts for emergency repairs — they are reimbursable.
- File the Claim Promptly — Contact your insurance carrier within 24-72 hours. Provide: date of loss, type of damage (wind/hail/other), photos, and a rough estimate if available.
- Schedule Adjuster Inspection — The carrier sends a claims adjuster. Have your roofing contractor present during inspection — they can point out damage the adjuster might miss, especially on membrane seams and flashings.
- Get Contractor Estimates — Obtain 2-3 estimates from licensed roofing contractors who work with insurance claims. Ensure estimates use Xactimate pricing (industry-standard insurance estimating software).
- Review the Adjuster Report — Compare the adjuster's scope of work with your contractor's estimate. Common disputes: matching undamaged adjacent slopes, code upgrades (building code may require upgrades the adjuster didn't include), and overhead & profit calculation.
- Negotiate if Necessary — If the adjuster's estimate is lower than your contractor's, submit a "supplement" with additional documentation. You have the right to use a public adjuster (typically 10% of claim) if negotiations stall.
- Approve and Schedule — Once you agree on scope and price, the carrier issues an Actual Cash Value (ACV) payment. After replacement, submit the final invoice for the Recoverable Depreciation (RCV - ACV = depreciation held back until work is complete).
📅 Roofing Season Calendar by Region
Plan your roofing project for optimal weather windows. Off-season installs may require special procedures and cost 10-20% more.
| City | Climate Zone | Roofing Season |
|---|---|---|
| Dallas TX | 2A (Hot-Humid) | March-November (peak: April-June, September-October) |
| San Antonio TX | 2A (Hot-Humid) | March-November (peak: April-June, September-October) |
| Houston TX | 2A (Hot-Humid) | Year-round (avoid peak hurricane season June-November for major projects) |
| Chicago IL | 5A (Cold-Humid) | April-October (peak: June-August). Winter installs require special adhesive and heat sources. |
| Phoenix AZ | 1B (Very Hot-Dry) | Year-round (avoid July-August peak heat for worker safety). Peak season: October-April. |
| Denver CO | 4B (Mixed-Dry) | April-October (peak: June-August). Hail damage repairs spike June-July. |
| Atlanta GA | 3A (Warm-Humid) | March-November (peak: May-July, September-October) |
🛡️ Insurance & Compliance AdvisoryFirestone RubberGard EPDM has the longest documented field performance of any single-ply membrane (35+ years on buildings in all climate zones). For insurance claims: EPDM's 300% elongation provides superior resistance to thermal movement and building settlement — if an EPDM roof leaks, the cause is almost always a seam failure or flashing failure, not membrane degradation. This is important for subrogation: the membrane manufacturer is rarely at fault for an EPDM leak. Ballasted EPDM systems have the best hail resistance of any single-ply system — the stone ballast (10-15 lbs/sq ft) absorbs impact energy that would puncture TPO or PVC. Document ballast specification for hail claims.

Frequently Asked Questions
What is the expected lifespan of Firestone RubberGard EPDM?
Firestone RubberGard EPDM has documented field performance of 35+ years on properly maintained roofs. The National Roofing Contractors Association (NRCA) estimates EPDM service life at 25-35 years for 60 mil membranes in fully-adhered applications. The limiting factor is typically seam integrity at 25-30 years, not membrane degradation.
Can EPDM roofing be installed in cold weather?
Yes. Unlike TPO and PVC which require hot-air welding at 900°F+, EPDM seams are sealed with pressure-sensitive splice tape (QuickSeam) that can be applied at temperatures as low as 40°F. This makes EPDM the preferred membrane for winter installations in cold climates.
