Holcim Elevate, the commercial roofing division formerly operating as Firestone Building Products, supplies single-ply TPO and EPDM lines along with insulation and accessory components we specify on Roanoke Valley projects where the product's published wind-uplift data and warranty structure fit the building. As with any manufacturer we work with, the specification follows the building's actual exposure and traffic, not a default preference.
Elevate's TPO membrane range covers the standard 60-mil specification we use across most Roanoke Valley low-slope commercial buildings, distribution space along I-81, single-story retail, and light-industrial facilities, with mechanically attached installation as the typical approach on a sound deck. Their EPDM line, including ballasted and adhered options, is relevant where an existing roof assembly's insulation and flashing package was originally specified around rubber membrane chemistry and a recover project needs to stay compatible with those existing materials rather than introduce a mismatched membrane class.
We evaluate Elevate's product lines against the same criteria we apply to every manufacturer: deck condition, rooftop traffic, and the site's specific wind exposure, before recommending a membrane class and thickness.
Elevate publishes fastening patterns and wind-uplift performance data tied to specific deck types and attachment methods, and we calculate the corner and perimeter fastening density for a given Roanoke Valley project against that published data, adjusted for whether the site falls under typical valley-floor Exposure C wind pressure or a higher topographic exposure near a ridge crest or escarpment along the Blue Ridge Parkway corridor.
Deviating from the manufacturer's tested and published assembly, even with a fastening pattern that appears adequate, can complicate warranty coverage later, so our installation follows the documented detail rather than a field adjustment.
Any single-ply membrane on a Roanoke Valley roof faces frequent freeze-thaw cycling given the elevation range between the valley floor and the surrounding ridgelines, and seam performance over years of that cycling depends on the weld or adhesive bond being properly cured at installation. We follow Elevate's published minimum-temperature guidance for seam procedures and schedule installation around those thresholds accordingly.
On EPDM specifically, adhesive-cured seams are more sensitive to ambient humidity and temperature during installation than a hot-air weld, and our crews check site conditions against the manufacturer's application parameters before committing to seam work on a given day.
Elevate offers insulation and cover board products designed to work as a tested assembly with their membrane lines, and using compatible components across the full roof assembly, insulation, cover board, membrane, is often a condition of the manufacturer's stronger warranty tiers. On recover projects where the existing insulation is a different manufacturer's product, we document that and confirm compatibility before specifying Elevate membrane over it.
Cover board selection also affects hail and impact resistance, a factor we weigh on Roanoke Valley buildings exposed to severe thunderstorm activity common in this region's warmer months.
Elevate's warranty terms vary by membrane thickness, attachment method, and contractor certification status, with longer no-dollar-limit coverage typically requiring installation by a manufacturer-credentialed contractor following published detail drawings and, in many cases, a manufacturer field inspection before issuance. We confirm the applicable warranty tier during project scoping so the specification decisions made up front support the coverage the owner expects.
We document our certification status and the completed assembly details as part of every Elevate project file, since that documentation is what supports a warranty claim if one is ever needed.
Yes, Firestone Building Products' commercial roofing division was rebranded as Holcim Elevate. The product lines and manufacturing continue under the new name, and we specify them using the same published fastening data and warranty requirements as before the rebrand.
We most often specify Elevate's TPO membrane for distribution, retail, and light-industrial buildings, with their EPDM line reserved for recover projects where the existing roof was originally specified around rubber membrane chemistry. Product selection follows the building's deck, rooftop traffic pattern, and existing assembly history.
Often yes, the stronger warranty tiers typically require using manufacturer-tested compatible components across the assembly, insulation, cover board, and membrane together. We confirm cover board compatibility during specification, particularly on recover projects with existing insulation from a different manufacturer.
We follow Elevate's published minimum-temperature guidance for seam and adhesive work and schedule installation around those thresholds. Seam integrity through repeated freeze-thaw cycling depends on a fully cured bond at install, which is a manufacturer specification issue we hold to closely in this climate.
Often yes, provided moisture cores confirm dry insulation and a sound deck, and the building has not reached the code limit on membrane layers. Staying within compatible manufacturer components on a recover can simplify the resulting warranty structure.
