Elevate PVC KEE Roofing System

Specify Elevate PVC KEE for superior performance and exceptional value. Elevate uses a custom blend of PolyVinyl Chloride (PVC) and DuPont™ Elvaloy® Ketone Ethylene Ester (KEE) for enduring plasticizer retention, long roof life, and fewer maintenance costs.

The Elevate PVC KEE single-ply roofing membrane is ideal for a wide range of low-slope commercial roofing applications and building types, including airports, restaurants, food processors, and manufacturing facilities due to its inherent resistance to grease, fuels, air conditioning coolants, and other harsh chemicals. This resistance paired with UV inhibitors and high-performance watertight heat-welded seams makes for a roofing membrane you can stand behind, decade after decade.

It's all in the Elevate formulation and brand promise. The Elevate PVC KEE formulation has provided quality in-market performance for 30 years and counting. Our PVC formulation with DuPont™ Elvaloy® Ketone Ethylene Ester high molecular-weight polymer additive enhances the already exceptional qualities of Elevate PVC. This solid plasticizer bonds with the PVC to provide consistent and dependable long-term plasticizer retention, ultimately promoting excellent flexibility and durability for the roofing system's service life - which we confidently back by the Elevate Red Shield Limited Warranty and brand promise.

The Elevate brand promise, Nobody Covers You Better, ensures you receive the quality product and resources you need to tackle any commercial roofing project. Our robust product research, development, testing, industry experience, and sales and technical support make sure of it.


A Formulation Backed by In-Market Performance

Time is the only way to measure a single-ply roofing system, and Elevate PVC KEE has stood the test of time. Elevate’s PVC KEE membrane formulation uses DuPontTM Elvaloy® KEE, a solid plasticizer that bonds with the PVC to provide consistent and dependable long-term plasticizer retention. And we back our PVC KEE with the Elevate Red Shield Limited Warranty of up to 30-years on 80 mils.

Unparalleled Chemical and Fire Resistance

The chemistry of a PVC KEE membrane makes it inherently resistant to harsh chemicals and grease and thus ideal for installations on airports, restaurants, and food processing facilities.

PVC is the most fire-resistant single-ply roofing membrane, and Elevate PVC KEE is no different. Elevate PVC KEE membranes are fire-resistant, difficult to ignite, have a low heat release, and are self-extinguishing in the event of a fire. PVC roofing is often used in construction because of its inherent ability to reduce flame spread.

Highly-Reflective for Sustained Energy Efficiency

Elevate PVC KEE is a highly-reflective cool roof solution that's designed to reflect sunlight and absorb less heat. As a highly reflective roofing membrane, it keeps the interior of the building cooler and can help lower air conditioning costs. PVC KEE can also help mitigate the urban heat island effect, contributing to cooler cities, lower energy consumption, and better air quality.

Elevate PVC KEE meets the California Energy Efficiency Standards for Residential and Nonresidential Buildings (Title 24). These standards define cool roofs in California to have a minimum three-year aged reflectance of 0.55 and a minimum thermal emittance of 0.75 for low-sloped nonresidential buildings. Elevate’s PVC KEE membranes are also listed with the Cool Roof Rating Council (CRRC).

Quick Installation Plus Long-Term Durability

Elevate PVC KEE can be installed quickly in a range of temperatures. No seam adhesives, tapes, or caulks are required. Instead, membranes are seamed using a hot-air gun for heat-welded bonds that form a permanent, durable, and watertight monolithic roof. A reinforced membrane and a reliable PVC KEE formulation promote notable impact and puncture resistance for a long-term commercial roofing solution. VSH PVC KEE assemblies are also available for adhered over top of either Hailgard or Oriented Strand Board (APA rated).
