How To Read These Comparisons
Four panels. One clear picture.
Pristine and Korellis both serve Northwest Indiana commercial property owners. The difference comes down to the system installed on your roof. Four panels below cover materials, cost and labor, service life and warranties, and the difference between liquid roofing and rolled roofing.
Panel 1 of 4
Materials and Chemistry
What goes on your roof determines everything that follows. Service life, maintenance cost, and energy performance.
| Pristine | Korellis | |
|---|---|---|
| Primary System | Seamless liquid urethane and acrylic | Rubber membrane and plastic-wrap TPO |
| Seams | Zero. Monolithic application across the entire field | Seam-dependent across the field |
| Adhesive Required | None on liquid systems | Required for sheet membranes |
| Insulation Upgrade | Add inches under a liquid seal | Limited by membrane compatibility |

Cost and Labor
The system you choose determines how much gets spent on labor, disposal, and downtime. Not just materials.
| Pristine | Korellis | |
|---|---|---|
| Labor Model | Skilled crews, lower labor cost | Premium union pricing |
| Tear-Off Required | Avoided when possible. Overlay friendly | Typically required for replacement |
| Disposal and Downtime | Minimal. Work continues on site | Dumpsters, fees, extended schedule |
| Patch Option | Liquid patch as first consideration | Limited. Patch quality varies by seam |

Service Life and Warranties
Three systems. Three distinct warranties. These are not interchangeable. Each warranty is tied to a specific product path.
| Pristine | Korellis | |
|---|---|---|
|
Tier 1 Liquid urethane or acrylic over metal |
10 YearsFull Pristine warranty | Manufacturer-limited, often prorated |
|
Tier 2 Liquid urethane or acrylic over EPDM, TPO, bitumen, BUR, or concrete |
20 YearsFull Pristine warranty | Manufacturer-limited, often prorated |
|

| Maintenance Path | Walk it, inspect it, recoat it | Patch, repatch, eventual replacement |
| Energy Performance | Reflective topcoat plus added insulation lowers your NIPSCO bill | Varies by membrane color and condition |

Liquid Roofing vs Rolled Roofing
Not a Korellis comparison. This is the question owners ask most: what exactly is the difference between a liquid system and a rolled membrane?
Pristine installs both. Understanding the difference helps you choose the right system for your property, not the easiest one for a contractor to install.
| Liquid Urethane or Acrylic | Vinyl PVC Membrane | |
|---|---|---|
| Form | Liquid chemistry, applied wet, cures solid | Rolled sheet, 6-foot by 100-foot rolls |
| Installation | Three-layer cake with fabric-reinforced mesh | Heat-welded seams across the field |
| Bond | Chemical bond. Like industrial epoxy | Mechanical and welded |
| Best For | Overlay over existing roof, no tear-off | Full system installations and new builds |
| Not To Be Confused With | Hardware store bucket coatings. Those are paint, not chemistry. | Old rubber EPDM or plastic-wrap TPO. Entirely different material. |

10
Year warranty
Liquid urethane or acrylic over metal
Applied over a metal substrate. Seamless, recoatable, and warrantied for a decade.
20
Year warranty
Liquid over any other substrate
EPDM, TPO, modified bitumen, BUR, and concrete. Overlay friendly. No tear-off required.
25
Year warranty — 300 months
Vinyl PVC FLEXION 2.0

Frequently Asked Questions
Straight answers. No runaround.
What system does Pristine install?
Seamless liquid urethane and acrylic, with vinyl PVC membrane available when the application calls for it. Liquid coatings are Conklin-manufactured.
Do you always tear off the existing roof?
No. Most projects we overlay. Tear-off only happens when the substrate is unsalvageable.
How long does a Pristine roof last?
Three product paths, three warranties. Liquid over metal is warrantied 10 years. Liquid over any other substrate including EPDM, TPO, modified bitumen, BUR, and concrete is warrantied 20 years. Vinyl PVC membrane is warrantied 25 years. A simple recoat at the end of the warranty window extends the service life indefinitely.
