Holcim Elevate: The EPDM Name Under New Ownership

Owners who remember this product line as Firestone Building Products sometimes ask why the name changed on their proposal. Firestone's commercial roofing division was sold and rebranded as Elevate, now operating under Holcim's ownership, and the product lines and manufacturing continuity carried through the transition. We still spec their EPDM regularly, since it is one of the deepest rubber roofing catalogs in the market and fits a specific slice of Ontario's building stock well.

What We Install From the Elevate Line

Elevate's EPDM product covers both the black and white sheet options detailed on our black EPDM and white EPDM pages, in the full range of ballasted, mechanically fastened, and adhered attachment methods, with a manufacturing history in this specific membrane chemistry that goes back further than most competitors. Their TPO line rounds out the single-ply portfolio for buildings where the reflective, heat-welded membrane is the better spec, covering the same 60-and-80-mil territory we detail on our TPO pages.

On roofs where EPDM's flexibility and detailing advantage matters , complex existing conditions, numerous roof-mounted units, tie-ins to older parapet construction , Elevate's EPDM catalog gives our crews a deep bench of flashing accessories built specifically around that membrane's install requirements, rather than accessories adapted from a different product family.

Where This Fits Ontario's Building Stock

We reach for Elevate most often on cold storage and food-processing buildings around the industrial parks near Rancho Cucamonga and Jurupa Valley, where EPDM's long field-performance track record and the manufacturer's depth in that chemistry give facility owners and their insurers a comfortable amount of history to underwrite against. It is also a common recommendation on older medical office and institutional buildings around Chino Hills and Upland with complex existing roof geometry, where EPDM's larger sheet format and adhesive-seamed detailing handle irregular framing more efficiently than a heat-welded thermoplastic. Food distribution buildings near the Ontario Airport corridor are a similar case, where the product's long service history in refrigerated and temperature-cycled environments gives facility managers a documented basis for their equipment insurance underwriting.

Warranty Structure

Elevate's no-dollar-limit warranties follow the same industry-standard bands as other major manufacturers, typically 15 to 30 years, scaled to membrane thickness, attachment method, and flashing detail quality rather than a flat number regardless of installation. A 90-mil EPDM field with enhanced flashing detail generally qualifies for a longer term than a thinner sheet with standard detailing, and we build to the detail level the target warranty requires before submitting the job for manufacturer inspection. As with any NDL program, the term stays valid only if the owner keeps up with basic maintenance , seam probing, drain clearing, and prompt repair of any accidental roof damage , and we walk through that obligation at closeout so it does not become a surprise years later.

• Product lines available: EPDM (black and white, 45 to 90 mil), TPO (60 and 80 mil)
• Attachment methods: ballasted, mechanically fastened, fully adhered
• Warranty terms: typically 15 to 30 years NDL, scaled to thickness and detail quality
• Manufacturing history: long-running EPDM product line, formerly under the Firestone Building Products name
• Best-fit buildings: cold storage and food-processing facilities, older buildings with complex roof geometry
• Closeout process: manufacturer inspection required before warranty issuance

How We Weigh Elevate Against Other Manufacturers

For an EPDM job specifically, Elevate's manufacturing depth in that chemistry is a real factor in the recommendation, since the accessory catalog and installation guidance developed specifically for their rubber membrane line runs deep. For a TPO job, their product competes on the same basis as any major manufacturer's line , thickness, warranty term, and current material availability. Where owners sometimes assume TPO is simply the newer, better option regardless of building type, we push back on that assumption whenever the roof's own conditions argue for EPDM instead, since the right membrane choice depends on the building, not on which chemistry came to market more recently. We name the specific product and manufacturer in every proposal so the owner knows exactly what is being warrantied and by whom.

Common Questions on Holcim Elevate Roofing

Is this the same product as Firestone EPDM?

The product line carries forward from what was Firestone Building Products' commercial roofing division, now operating under Holcim ownership as Elevate. Owners with an existing Firestone roof from prior years are dealing with the same manufacturing lineage under the new name.

Does the ownership change affect an existing roof's warranty?

Warranty administration continuity through a corporate rebrand is a manufacturer administrative matter. We recommend owners with questions about a specific existing warranty confirm current terms directly, and we can help facilitate that conversation as part of an inspection.

Is EPDM still a good choice compared to newer TPO products?

For roofs with complex existing geometry, heavy penetration density, or unconditioned space where Title 24 reflectance is not required, EPDM remains a strong option. For open-field conditioned buildings needing cool-roof compliance, TPO is usually the more straightforward spec.

Can Elevate EPDM and Elevate TPO be combined on one roof?

Yes, with correct transition flashing between the two membrane types at any tie-in. Sourcing both from one manufacturer simplifies the accessory selection at that transition point.

How do you decide between Elevate and another EPDM manufacturer?

We compare sheet thickness options, warranty terms, current material lead time, and how the specific accessory catalog handles the building's existing conditions. The decision is job-specific rather than a fixed preference for one manufacturer over another.
