Holcim Elevate Roofing Systems in Sherman, TX

Rubber roofing sheets shrink as they age. Over years of sun and heat, the polymer loses plasticizing oils and tightens, pulling at every edge it touches. The pull concentrates at corners, at curbs and along walls, where the sheet is held in place. A shrunk sheet leaves a gap behind a flashing or lifts off a corner. Holcim Elevate, formerly Firestone Building Products, makes single-ply membranes in rubber and thermoplastic families, along with metal roof panels and insulation. A Sherman, TX building may carry roof papers and warranty files that still use the older name. Swings from 113 F to -3 F on record make the pull stronger here, so we look for it early.

A roof installed years ago may carry papers under the Firestone Building Products name. The company now operates as Holcim Elevate. For an owner, the change creates a trail to follow. Which name appears on the specification? Which name sits on the warranty certificate? Which entity answers a notice today?

We gather the papers, record the names on each and note the dates. We then confirm how the issuer wants notices sent and what records it expects. The result goes into the building file in plain language, so a new manager can act without reading three generations of paperwork. Our warranty management keeps that file current as inspections, repairs and storm events are added.

Dates matter on these papers. A warranty term runs from a start date, and a repair made outside the stated terms can change coverage. We list the start date, the term and the number of years remaining, and we feed that number into the replacement plan, so a section with a few years left is funded in the right order. If the original installer has changed names or closed, we note that too, because it affects who can be called for warranty work.

Single-ply sheets divide into cured rubber and thermoplastic. EPDM is a cured rubber that joins with adhesive or tape. TPO and PVC are thermoplastics that join by heat welding. A black or gray sheet with taped laps points to rubber. A white sheet with welded laps points to a thermoplastic.

We identify the family by looking at the surface and the seam, then confirm with a probe and, where needed, a core. The family determines the repair. A rubber sheet takes primer, tape and adhesive. A thermoplastic sheet takes a hot-air weld. Using the wrong method gives a patch that looks fine and peels in a season. The file records the family, the thickness, the attachment and the insulation below.

Other manufacturers sell comparable families, and the same identification steps apply to the thermoplastic sheets from Sika Sarnafil and the single-ply lines from Carlisle SynTec. What matters to the owner is the family on the roof, not the logo on the roll.

On a rubber roof, we press along each splice to check for lift. We look at tape edges, at the ends of laps and at corners where movement collects. We check pipe boots and curb flashings for cracks, shrinkage and gaps. We look for gaps where the sheet has pulled away from a wall.

Repairs begin with cleaning. Rubber surfaces gather dust and oils, and adhesive will not hold on a dirty sheet. We clean, prime, set new tape or patch material, and press it down with a roller. Corners get extra attention, because those are the spots that fail again. Where shrinkage has pulled the sheet tight, we may add relief at the termination to let it move without tearing.

Seam tape deserves its own check. Tape that was applied over a dusty or damp surface can look sound for a season and then start to creep. We lift suspect tape at an inconspicuous spot to see how well it has bonded, and we measure the width of exposed adhesive at edges. A tape edge that has curled up even slightly gets resealed with a new cover strip, and the repair is logged by lap number.

Spring storms test every single-ply sheet. North and Central Texas tornadoes peak in April and May, and on June 8, 2025 half-dollar stones were reported northwest of Denison while an EF1 touched down southwest of Sherman. Hail can bruise insulation under an intact sheet. Wind lifts edges and corners.

After an event we walk the roof, probe edges and scan for moisture. The edge metal and perimeter attachment get a close look, because uplift concentrates there. Ice matters too. In December 2013, ice reached 4 to 5 inches in thickness across Sherman and Denison, and ice can block drains and load the deck. Our wind damage repair and hail damage repair follow these checks and keep dated photos for any claim.

The same manufacturer also supplies metal roof panels and roof insulation. A standing seam metal roof sheds water quickly and has few seams to open, which suits some building types. It also expands and contracts, so clip design and panel length matter. A metal retrofit over an existing low-slope roof can avoid a tear-off, subject to structure and code.

We compare options in the written scope. We show the first cost, the maintenance each system needs and the likely service life. We also check the existing structure. Not every deck or frame will carry a retrofit, and the scope says so plainly. For insulation, the thickness and type follow the local requirements in force, and the file records both.

Insulation behaves as part of the roof. Where the existing insulation is dry and sound, we leave it in place and say so. Where it is wet, we remove it and replace it with boards that suit the new system and the code. The scope lists the thickness, the facing type and the fastening, so the owner knows what sits under the membrane and why.

Uplift, insulation and fire details in any replacement depend on what the local building department enforces. We confirm requirements with that authority before pricing a roof in Sherman, Denison or the towns around them.

Industrial buildings in Progress Park, where tenants include Tyson Foods, Sunny Delight and Kaiser Aluminum, and public buildings like schools and hospitals each bring access rules. We confirm hatch locations, equipment, tenant hours and material routes before work starts. The scope sheet carries the plan for the crew and the owner alike.

Cost drivers appear as separate lines. The area, the amount of wet insulation removed, the attachment method, the edge metal and the access for lifts and cranes each move the number. Hail and wind history affects the scope too, because bruised insulation under a sound sheet must still be removed. The owner sees which lines are fixed and which depend on what the tear-off reveals.

Is Holcim Elevate the same company as Firestone Building Products?

The firm that made Firestone Building Products roofing now operates as Holcim Elevate. Older papers may use the former name.

Which name goes on a warranty notice?

Whichever name the certificate and the issuer's instructions give. We confirm it before sending anything.

Why do rubber roofs pull at their corners?

The sheet shrinks as it ages. The pull concentrates where it is held, at corners and walls.

Can a rubber roof be welded?

No. It joins with adhesive or tape. Thermoplastic sheets are the ones that weld.

Is a metal retrofit always possible?

No. The structure and code decide. We check both before pricing.
