Holcim Elevate Roofing (Formerly Firestone)
Rockford, IL
A roof put down under the Firestone name is sold and documented under a different one today, and the January thaw does not care about the rebrand. Water still works into the same laps and flashings, and the roof still has to carry whatever Rockford, IL piles on it. The company that made UltraPly TPO and PVC, RubberGard EPDM and ISO 95+ polyiso as Firestone Building Products now sells them as Holcim Elevate, which means an owner may hold paperwork under one name and a roof label under another. That is a confusing way to buy a roof, and it is why an owner has to be more careful, not less, about what is actually on the deck.
Before you call anyone, find the original roof file. The date, the product and the warranty form are worth more than any sales pitch.
Trace the roof back to its original paperwork
Many commercial roofs carry the Firestone name on the sheet, the warranty and the permit file, and that history is useful. Dig out the original proposal, the manufacturer warranty, any inspection reports and every repair invoice. They tell you which membrane is up there, how it was attached, how thick the insulation is and whether the manufacturer's coverage is still in force. If a warranty is active, repair work usually has to follow the manufacturer's process, and a patch done outside it can complicate a claim. We will look at the roof, identify the system and photograph the details, but the file is yours to find. A short call to the manufacturer with the roof address and installation date often turns up records an owner has lost.
No file at all? Then a core sample and a survey become your documentation. Write down what they find and store it with the building records.
Match UltraPly, RubberGard or PVC to what the roof carries
The lineup splits three ways. RubberGard is the EPDM, a black rubber sheet with a long record on northern roofs, and it keeps its flexibility through hard freezes. UltraPly TPO is the white welded sheet, favored on wide, open roofs where reflectivity and a clean seam matter. UltraPly PVC is the tougher cousin when grease, oils or chemicals reach the membrane. Choose among them by looking at the roof, not at the catalog. A building with a lot of rooftop equipment and foot traffic leans one way, a long, clear warehouse span leans another, and a kitchen exhaust leans toward PVC. Each sheet fails in its own way: EPDM roofing at its splices and flashings, TPO roofing at its welded seams and perimeter attachment.
Under the sheet, ISO 95+ polyiso is the insulation most often paired with these membranes, and a cover board over it is worth pricing wherever hail is a risk. A single November storm in 2020 left hail up to an estimated 1.25 inches near Rockton, and a thin sheet over soft board is the combination that bruises. A firmer board costs a little more per square and can save a leak claim later.
If a bidder lists the product without saying why, ask for the reasoning in writing.
Think about the big roofs around the airport
Big roofs near Chicago Rockford International Airport show how weather and scale combine. The airport holds a 200,000 square foot AAR maintenance facility, a 90,000 square foot cargo building with more than 20 truck docks and Amazon's expanded terminal, and buildings of that size usually mean long spans, many penetrations and heavy traffic beneath the roof. Wind speeds up across open ramps, so edge and corner attachment get tested first. Freeze-thaw cycling pulls on every seam and flashing, and meltwater from a roof of that size has a long way to travel to a drain. Whether the sheet is UltraPly or something else, the details are what decide the roof's life: attachment at the perimeter, drain placement, sumps and the flashing at every curb and penetration.
Walk the roof after the first thaw each year and photograph the same spots. A change from last year is the first warning.
Price the repair beside the replacement, then compare
The honest way to handle an aging Holcim Elevate or Firestone roof is to price a repair and a replacement at the same time. Repair means seams, flashings, drains and punctures, with insulation tested and left in place if it is dry. Replacement means tear-off or recover, new insulation to meet the 2021 energy requirements the state adopted and a fresh warranty. If the repair costs a small share of the replacement and buys several more winters, it is the right call. If the insulation is wet or the sheet is brittle, spending on patches throws money away. A fair contractor will say which situation you are in. Confirming through roof warranty management whether any coverage is left to protect decides how the repair has to be done.
Do not let anyone push a full replacement without a moisture scan on the table.
Schedule around the thaw and the peak freight season
The best weeks for single-ply work in Rockford run from late spring through early fall, when sheets are pliable and surfaces dry out. Cargo operations such as UPS and Amazon Air at the airport run on ramp and dock schedules, so roof work there has to be sequenced around them. A campus such as Rock Valley College, with 217 acres at North Mulford and Spring Brook roads, usually has the most open roof access when classes are out. If you are comparing manufacturers for the same roof, put Sika Sarnafil and Duro-Last through the same questions, and let the answers guide the decision.
A leak in the meantime needs a dry-in, not a cold-weather rebuild.
Before ordering material, confirm the project drawings call out the current product name and the specific accessories required at edges, curbs, drains and terminations. A roof assembly is only as dependable as its transitions, so review the detail sheets with the installer and the owner's representative before field work begins. On large industrial roofs near Loves Park or distribution properties in the South Rockford Logistics Corridor, staged deliveries and labeled rolls also reduce the chance that the wrong membrane is installed in a work zone.
Questions Owners Ask
Is Holcim Elevate the same company as Firestone?
The product lines that carried the Firestone name now sell as Holcim Elevate. Older roofs still show Firestone on the membrane and the warranty, so keep both names on file when you request records or repairs.
Can my old Firestone warranty still be honored?
Maybe. Coverage depends on the form, the roof's age and whether maintenance and repairs followed its terms. Locate the paperwork first, then ask the manufacturer directly about status.
Should I choose TPO or EPDM for a Rockford building?
Look at the roof. EPDM remains a dependable choice in hard freezes, TPO suits wide open roofs and PVC suits grease or chemicals. A core sample and an equipment walk will point to one.
What does a repair on one of these roofs actually involve?
Cleaning the old sheet, cutting out the failure and welding or splicing a patch that overlaps it on every side. Flashings at walls, curbs and drains get the most attention, since that is where winter wins.
How do I confirm the insulation is worth keeping?
An infrared scan on a cool evening, followed by core cuts at suspect spots. Dry polyiso can stay. Wet board comes out before any new membrane goes on.
