Single-Ply Membrane

What is a Single-Ply Membrane? (SPM)

We offer a complete waterproofing system for EPDM (ethylene propylene diene terpolymer) Aged Thermoplastic Olefin (TPO), Polyvinyl Chloride (PVC) and Chlorosulfonated Polyethylene (CSPE) roofs that can improve and extend the life of the existing Single-Ply roof.

Conklin’s Single-Ply Membrane roofing systems are made with premium thermoplastic membranes. During installation, membrane rolls are overlapped and welded together to form an exceptionally durable, waterproof, energy-efficient shield that will deliver unsurpassed protection for years to come.

Benefits of SPM System

  • White, reflective finish
  • Highly resistant to wind and hail. Performs well in any climate
  • Minimizes movement on the whole building
  • Cooler inside temperatures
  • 20 or 25 year, non-prorated warranty

The Process

Prepare Substrate

  • Cleaning
  • Removing debris or existing roof
  • Repair / Patch existing damage
  • Application of Rust Off® Rust and oxide remover


We install a layer of suitable board stock, which the membrane will be attached to. The board stock provides a layer of protection from debris, as well as creates a floor of insulation to help reduce cost associated with building heating / cooling.

Attach Membrane

Our ENERGY STAR-rated, thermoplastic membrane provides fantastic protection from the elements. Its unique thermoplastic formulation has been reinforced with DuPont® Elvaloy® for superior strength, durability, and flexibility. Furthermore, it is naturally fire-resistant and has been recognized by most major code approval agencies. Flexion XL is an excellent choice for both new and re-roofing applications.
