Holcim Elevate Commercial Roofing in Davenport, IA

The closeout binder in the facilities office says Firestone Building Products. The new bid on the desk says Holcim Elevate. The property manager asks the obvious question: are these the same roof?

They are the same family. Firestone Building Products is now Holcim Elevate, and the product lines that facilities teams know from older paperwork carry on under the new name. For owners in Davenport, IA the practical job is to read the old documents correctly, match them to current materials, and decide whether the roof needs a repair, a restoration or a replacement. We install Holcim Elevate systems and repair the ones in place.

A roof put down under the Firestone name keeps its identity in the field. The sheet, the seam tape, the pipe boots and the fastener plates are what they were. What changes is the letterhead on warranty questions and the product catalog a bid is written from.

That gap causes confusion at the worst moment, usually when a leak is active and someone is hunting for a phone number. We pull the closeout file early, record the product name from the roll labels or the drawings, and write both names on our scope. If a warranty is still running, the next step is a call to the maker to learn what repair work keeps the coverage in place. Keeping those papers in one warranty file means the answer is on hand next time.

Three sheets carry the line. UltraPly TPO is the white thermoplastic for general roofs, with welded seams and a reflective surface. UltraPly PVC is the chemical-resistant sibling for grease and fumes. RubberGard is the EPDM rubber, with long sheets that reduce seams over a big deck.

Choosing among them is a conversation about the building. A clinic wing with a kitchen exhaust nearby wants PVC. A low-traffic warehouse wants TPO, the sheet Carlisle SynTec and GAF also sell. A roof that takes hail often, and a roof that already carries ballast, is a candidate for EPDM. For a second opinion on the same sheet types we tell owners to price Sika Sarnafil PVC against the Holcim Elevate PVC, since the welding and the details differ.

A membrane is half the system. Polyiso insulation and cover boards carry the load and the energy value, adhesives bond the sheet, and metal flashing finishes the perimeter. Holcim Elevate sells matched parts for all of it, and the published details assume you use them together.

The edge is where the details earn their keep. Coping, fascia and drip edge are wind elements, and after the July 2024 derecho that crossed the region they are often the first pieces to show damage. Fastener spacing at the corners and the lap of the metal over the membrane both come from the maker's detail sheets. We install edge metal to those details, and a pull test at the perimeter comes before we call a section done.

Genesis Health System has its headquarters in Davenport and 760 licensed beds spread over six locations in Davenport, DeWitt, Silvis, Aledo and Maquoketa. Trinity hospitals in Moline and Rock Island employ about 2,700 and 1,848 people. Rooms under a hospital roof are rarely ones that can be shut for a repair.

A hospital roof job starts with the air. We ask facilities where the intakes are, what the infection control office requires and which floors are sensitive. Hot-air welding avoids flame and asphalt fumes, and we plan around imaging hours and procedure schedules. If a sheet has to come off over an occupied wing, temporary dry-in is staged before the old membrane is lifted.

The Bettendorf riverfront holds the Isle of Capri casino and hotel, plus a 24,000 square foot convention center on State Street. A roof at a hotel or convention center has to work around guests who sleep late and event calendars set months out.

For a hotel roof, we map the calendar first. Noisy work goes in the empty weeks, a small crew handles weekend call-backs, and room-level notices go to the front desk with dates. Rooftop kitchen exhaust is the usual PVC case. Pool and laundry vents add humidity, so we check the insulation around them first.

Two-inch hail fell on Davenport on April 7, 2020, and a derecho with winds up to 100 mph crossed the region on July 15, 2024. TPO and PVC take hail differently than EPDM does. A thermoplastic sheet over soft insulation can bruise under a large stone, while the rubber stretches and returns. We probe suspect areas and cut a core when a bruise looks like more than skin deep.

After wind, the first work is the perimeter. We look for lifted edge metal, pulled fasteners and billowed sheet in the field. Small repairs on a Holcim Elevate roof go in the same day, using matched patches and an inspection at the seam. Larger scopes get a written report with photos for the owner and the adjuster.

When reviewing a specified Holcim Elevate system, compare the membrane with the complete detail package. Edge securement, fastener plates, adhesives, insulation and flashing accessories have to match the approved configuration and the substrate. On existing roofs, identify the installed sheet before choosing a repair material; similar colors do not establish compatibility. We record product labels and repair locations in the closeout file, which gives the next maintenance visit a useful starting point.
