Firestone rubber roofing usually refers to EPDM roofing products historically sold by Firestone Building Products. That business became part of Holcim in 2021 and was rebranded as Elevate in 2022, so current product names, warranties, and sales channels may use the Elevate name. The best-known system is RubberGard EPDM, a synthetic rubber membrane used on many low-slope commercial roofs. Understanding the product lineup, installation choices, and maintenance needs helps property owners compare options and ask informed questions of roofing contractors.
What “Firestone Rubber Roofing” Means Today
Firestone Building Products developed and marketed roofing membranes and related materials for commercial and industrial buildings. After Holcim acquired the business, the roofing brand became Elevate. As a result, “Firestone rubber roofing” remains a common search phrase, but current product information and support may appear under Elevate.
In roofing, “rubber roof” most often means an EPDM membrane. EPDM stands for ethylene propylene diene monomer, a synthetic rubber designed to resist weathering and remain flexible across a range of temperatures. RubberGard EPDM is the central Firestone-associated rubber roofing product. It is not the same material as TPO or PVC, which are separate types of single-ply roofing.
Product availability, specifications, and warranty terms can change. A project should be specified using current manufacturer documents and the exact product names supplied for that job, rather than relying only on older Firestone literature or a general description such as “rubber roof.”
Common Firestone And Elevate Roofing Products
Firestone’s former roofing portfolio included several membrane types and system components. The principal distinction is between EPDM rubber and other single-ply materials. Accessories such as adhesives, flashings, cover boards, and fasteners are also important because they help make a complete roof system.
| Product or category | Material or purpose | Key consideration |
|---|---|---|
| RubberGard EPDM | Flexible EPDM membrane for low-slope roofs | Available in different thicknesses and installation configurations; confirm current options and specifications. |
| UltraPly TPO | Thermoplastic polyolefin single-ply membrane | Not rubber; seams are typically heat-welded. |
| PVC roofing | Polyvinyl chloride single-ply membrane | Not rubber; product details and chemical-resistance characteristics vary. |
| Roofing accessories | Adhesives, primers, seam materials, flashings, and related items | Compatibility with the selected membrane and system is essential. |
| Insulation and cover boards | Components below or above the membrane, depending on design | Selection affects thermal performance, attachment, and roof assembly performance. |
The terms “Firestone roof,” “Firestone EPDM,” and “Firestone rubber roofing” are sometimes used interchangeably, but they do not identify every part of a roof assembly. A specification should list the membrane, insulation, cover board, attachment method, flashing details, and approved accessories.
How RubberGard EPDM Roofing Works
An EPDM roof is a membrane-based roofing system. The membrane provides the primary water-shedding layer, while the rest of the assembly supports it, secures it, and connects it to roof edges, drains, walls, and penetrations. A typical low-slope assembly may include a structural deck, vapor control layer where required, insulation, a cover board, and the EPDM membrane.
EPDM sheets are manufactured in rolls and installed in large sections. Seams are joined using manufacturer-approved seam tape or other specified seam methods. Details around pipes, curbs, corners, drains, and edges require compatible flashing materials and careful workmanship. These areas are especially important because roof leaks often begin at transitions or penetrations rather than in the open field of a membrane.
EPDM systems can be installed in different ways, including mechanically attached, fully adhered, or ballasted configurations where the building design and manufacturer’s requirements allow. The right method depends on factors such as wind exposure, deck type, building height, roof geometry, insulation design, and local code requirements. A contractor should identify the proposed assembly in writing rather than simply stating that the membrane will be “rubber.”
Potential Benefits Of EPDM Rubber Roofing
Flexibility In Changing Weather
EPDM remains flexible in cold conditions and is commonly used in climates with substantial seasonal temperature changes. Its ability to accommodate movement can be useful on large roof areas, although performance still depends on proper design, attachment, and detailing. No membrane eliminates the need to account for building movement, wind uplift, or drainage.
Large Sheet Options
EPDM is available in sheet formats that can reduce the number of field seams compared with smaller pieces. Fewer seams may simplify portions of an installation, but seam quality remains critical. Sheet size must also be practical for roof access, handling, layout, and the chosen attachment method.
Repair And Maintenance Familiarity
EPDM is a widely used commercial roofing material, and trained roofing professionals are generally familiar with inspection and repair procedures. Punctures, damaged flashing, and open seams can often be addressed with compatible repair materials when the underlying roof remains suitable for repair. The exact procedure depends on membrane condition, contamination, age, and manufacturer guidance.
Design Options
EPDM roofing is commonly available in black and, in some product offerings, white or other reflective configurations. Color can influence solar reflectance and roof temperatures, but energy outcomes depend on the complete assembly, climate, insulation, HVAC design, and building use. A white membrane should not automatically be treated as a guaranteed energy-saving upgrade.
Firestone EPDM Versus TPO And PVC
Property owners comparing Firestone rubber roofing with other membranes should first distinguish the materials. EPDM is a thermoset rubber. TPO and PVC are thermoplastic membranes, whose seams are generally joined using hot-air welding. Each material has different installation practices, product formulations, and performance considerations.
| Feature | EPDM | TPO | PVC |
|---|---|---|---|
| Material type | Synthetic rubber | Thermoplastic polyolefin | Thermoplastic vinyl |
| Typical seam approach | Manufacturer-approved seam tape or specified seam system | Hot-air welding | Hot-air welding |
| Common appearance | Often black; reflective options may be available | Often white or light-colored | Often white or light-colored |
| Selection factors | Climate, attachment, seam detailing, and system compatibility | Weld quality, formulation, and project requirements | Weld quality, chemical exposure, and project requirements |
There is no universally best membrane for every building. Climate, roof use, rooftop equipment, grease or chemical exposure, wind requirements, budget, available contractors, and the desired service life all affect the decision. The manufacturer’s current technical data and a project-specific design are more useful than broad claims that one material is always superior.
Where Firestone Rubber Roofing Is Used
EPDM is primarily associated with low-slope and flat commercial roofs, including warehouses, retail buildings, offices, schools, and manufacturing facilities. It can also be used on certain residential low-slope sections, such as additions or porch roofs, when the assembly and slope are appropriate. The product is not automatically suitable for every roof shape or condition.
Roof slope and drainage matter. “Flat roof” is a common description, but roofs should be designed to manage water rather than retain it. Drains, scuppers, tapered insulation, and overflow provisions may be part of the design. Persistent ponding can complicate maintenance and may affect the roof assembly, so the cause and acceptable limits should be evaluated by a qualified professional.
Installation Details That Affect Performance
A quality membrane cannot compensate for poor system design or installation. Before work begins, the contractor should inspect the existing roof, verify the deck condition, identify moisture-damaged materials, and determine whether the project requires a tear-off, recover, or new construction assembly. Recovering over an existing roof may be restricted by code, manufacturer requirements, or the condition and moisture content of the existing materials.
Important installation checks include:
- Substrate preparation: The deck and underlying layers should be sound, clean, and suitable for the selected assembly.
- Insulation and cover board: Materials, thicknesses, joints, and attachment should match the project design.
- Seams: The crew should follow current manufacturer procedures for surface preparation, primer, tape, pressure, and seam inspection.
- Flashing: Perimeters, curbs, drains, pipes, and corners need compatible, properly installed details.
- Wind resistance: Attachment patterns should be designed for the building’s location, height, and exposure.
- Drainage: Drains and outlets should be open, correctly placed, and integrated with the membrane system.
Building codes and energy codes vary by jurisdiction. A roof replacement may require permits, insulation upgrades, or other measures under local rules. The building owner should confirm responsibilities with the contractor and local building department before work begins.
Costs, Warranties, And Contractor Questions
There is no reliable single price for Firestone or Elevate rubber roofing. Total project cost depends on roof area, access, tear-off needs, insulation, deck repairs, membrane thickness, attachment method, flashing complexity, location, and disposal requirements. Quotes should separate major components and clearly state what is included, such as removal, insulation, edge metal, drainage work, and repairs.
Warranty coverage also varies by product, assembly, installation, and current manufacturer terms. A product warranty is not necessarily the same as a system warranty, and neither should be assumed to cover every leak, maintenance issue, or building condition. Owners should review the actual warranty document for exclusions, required inspections, maintenance obligations, transfer rules, and claim procedures.
Useful questions for a roofing contractor include:
- Is the proposed membrane EPDM, and what is its current product name and thickness?
- Which insulation, cover board, adhesives, seam materials, and flashing products are included?
- How will the system be attached, and how was wind resistance determined?
- Will existing roofing be removed, and how will wet or damaged materials be identified?
- What drainage improvements or code-required upgrades are included?
- What manufacturer warranty is available, and what conditions must be met?
- Who will perform inspections and address issues during and after installation?
Maintenance And Repair Of EPDM Roofs
Routine maintenance can help identify small problems before they cause interior damage. Building owners should arrange periodic inspections, especially after severe weather and before seasons with heavy rain or snow. Inspections should look for debris, blocked drains, punctures, damaged flashing, loose edge details, and changes around rooftop equipment.
Foot traffic should be limited to necessary access and managed with appropriate walkways where specified. Contractors servicing HVAC equipment should avoid dragging tools or materials across the membrane and should report any damage. Unapproved coatings, sealants, cleaners, or repair patches can be incompatible with EPDM, so repairs should use materials and methods approved for the specific membrane system.
Signs that warrant professional evaluation include recurring leaks, open seams, visible membrane cuts, loose flashing, persistent ponding, blistering, or wet insulation. A leak’s interior location may not match the roof entry point because water can travel within the assembly. A qualified roofer can inspect the roof and determine whether a localized repair, broader restoration, or replacement is appropriate.
How To Verify Current Product Information
Because the Firestone Building Products name has transitioned to Elevate, owners may encounter both brand names in product documents and contractor proposals. They should verify current product literature, approved accessories, installation instructions, and warranty options through the manufacturer or an authorized distributor. The project documents should identify the exact membrane and system rather than rely on an outdated brochure or a generic brand reference.
Independent guidance can also help with roof planning. The National Roofing Contractors Association (NRCA) publishes roofing guidance and technical resources, while local building departments provide code and permit information. For energy questions, the U.S. Department of Energy and ENERGY STAR offer general resources on cool roofs and building efficiency. These sources complement, but do not replace, the project-specific instructions supplied by the membrane manufacturer.
