Can an Elastomeric Coating Save my Leaking TPO Roof?

AcryPly_Acrylic_Diagram_-_502TPO_2Elastomeric coating systems are ideal for restoring and renewing aged and failing TPO roofs. These roof coating systems allow you to avoid a costly and timely roof tear off, while achieving a highly reflective, watertight, energy efficient roof. 

TPO Roofing
TPO roofing is originally installed by welding the seams of the rolled out TPO to one another. These seams can cause roof failures and water penetration if the installation was not done correctly and/or after these seams have weathered.  Over time, the seams lose their ability to expand and contract with the rest of the roof causing rips and tears, eventually leading to a leaking roof - prompting building owners to look for a cost-effective solution.

Solution for Restoring TPO
Although TPO has been notorious for being difficult to coat over, the AcryShield A502 adheres directly to TPO with tenacious adhesion and extremely low levels of harmful VOC solvents. This elastomeric coating is ideal for TPO roofing because it eliminates the use of a separate primer prior to the installation of a base coat. Most roof coating manufacturers require a primer or etching rinse to be applied prior to a base coat. The application of primers and etching rinses generally entail the application, the chemical wash-off, and the capturing of the harmful chemicals before they run off into streets and streams. This additional primer step increases cost and lengthens the installation time frame. Using the AcryShield A502 base coat, contractors can quickly install your new roof coating system with direct adhesion to the TPO roof – saving the building owner time and money.

Two TPO Elastomeric Roof Coating Systems
We offer two elastomeric coating systems that are ideal for TPO roofing. The first is the AcryPly Roofing System; it restores your extremely weathered and aged TPO roof with the use of polyester reinforcing fabric across the entire rooftop to create an extremely durable and strong roof. The second is the AcryShield Roof Management System (ARM), it renews your TPO roof to new when it is in its initial stages of decomposition and only needs local reinforcement in necessary areas. Both systems provide you with the following benefits:

  • Eliminates a costly roof tear-off
  • Non-intrusive application process
  • Energy Efficiency and Cost Savings
  • Highly Reflective Cool Roof System
  • Renewable and Sustainable
  • Reduce Roof Maintenance
  • Seamless
  • Environmentally Friendly – No Harmful Primers/Etching Rinse and Ultra Low VOCs
