Non-reinforced TPO Roofing
Reliable Waterproofing for Roof Flashing, Corners, Penetrations and Complex Roofing Details.
Non-einforced TPO Roofing Membrane
Non-Reinforced TPO Roofing Membrane is a flexible thermoplastic polyolefin (TPO) sheet designed for compatible roofing detail applications where greater conformability is needed than a reinforced field membrane typically provides.
Without an internal reinforcing scrim, this membrane can be easier to shape around roof penetrations, inside and outside corners, parapet walls, pipe details, and other irregular areas. When formulated and approved for the intended roofing system, it can be hot-air welded to compatible TPO membranes to create watertight detail connections.
Non-reinforced TPO is generally used for roof flashing and detailing rather than as a direct replacement for reinforced field membrane. Product selection, detailing methods, and welding procedures should follow the roofing system manufacturer’s requirements.
Product Highlights
Excellent Flexibility for Roofing Details
The absence of an internal reinforcing scrim allows the sheet to conform more readily to suitable corners, curves, and irregular roof surfaces, subject to its formulation and thickness.
Ideal for Flashing and Penetrations
Designed for compatible detailing applications around pipes, drains, roof edges, parapets, and other areas where field membranes require specialized waterproofing transitions.
Hot-Air Weldable Connections
Compatible non-reinforced TPO sheets can be heat-welded to approved TPO roofing membranes, creating continuous connections without relying solely on exposed adhesive joints.
Adaptable to Complex Roof Shapes
Its flexible construction helps roofing professionals form detail transitions that may be difficult to complete neatly with a stiffer reinforced membrane.
Compatible with TPO Roofing Systems
When approved for the same roofing system, non-reinforced TPO can complement reinforced field membranes and compatible TPO flashing accessories to complete detail work.
Convenient for Detail Fabrication
The sheet material can be cut and shaped for suitable project-specific details, helping installers prepare flashing components for complex roof junctions.
Customized to Your Requirements
Thickness, width, length, color, reinforcement and packaging can be customized depending on product type and order requirements.
Application
Non-reinforced TPO roofing membrane is primarily intended for detailing applications in compatible TPO roofing systems.
Pipe and Roof Penetration Flashing
Detail around vent pipes, service penetrations, and other roof openings using approved flashing methods.
Inside and Outside Corners
Form compatible corner details at parapet junctions, raised roof edges, and changes in roof geometry.
Parapet Walls and Vertical Transitions
Complete waterproofing transitions where the horizontal roof membrane meets vertical walls or other building elements.
HVAC Curbs and Equipment Bases
Detail around compatible rooftop equipment curbs and raised mounting bases to help maintain continuity of the roof waterproofing system.
Roof Drains and Edge Details
Complete suitable drain transitions, roof perimeters, and other connection points in accordance with the approved system design.
Custom Roofing Details
Fabricate compatible detail sheets for irregular junctions and special roof features that require a flexible waterproofing material.
Installation Methods
Installation should follow the roofing system manufacturer’s approved detailing instructions. The following steps describe a general process for compatible non-reinforced TPO flashing applications.
- 1. Inspect and Prepare the Detail Area
Inspect the field membrane and the surrounding substrate. Remove dirt, moisture, and contamination, and identify the appropriate flashing detail for the penetration or transition.
- 2. Clean the Welding Surfaces
Prepare the existing TPO membrane and the detail sheet according to the manufacturer’s instructions. Use only approved cleaning products and preparation methods.
- 3. Measure and Shape the Detail Sheet
Cut the non-reinforced TPO material to the required dimensions. Shape it carefully around the detail without introducing excessive tension, wrinkles, or unsupported gaps.
- 4. Position and Weld the Membrane
Place the detail sheet in position and hot-air weld it to compatible TPO surfaces where permitted. Follow the specified welding temperature, speed, pressure, and overlap requirements.
- 5. Complete the Flashing Detail
Finish the pipe, corner, wall, or equipment transition using the approved detailing method. Add compatible accessories or termination components where required.
- 6. Inspect the Finished Work
Check welded edges, corners, terminations, and transitions. Perform the required seam-probing and quality-control inspections before accepting the finished detail.

FAQ
Non-reinforced TPO roofing membrane is a thermoplastic polyolefin sheet without an internal reinforcing scrim. It is commonly used for compatible roofing details and flashing where greater flexibility is needed.
Reinforced TPO contains an internal scrim that improves dimensional stability and mechanical strength. Non-reinforced TPO does not contain this scrim and can be easier to shape around suitable complex roof details. The two products generally serve complementary roles.
Common applications include pipe penetrations, inside and outside corners, parapet walls, HVAC curbs, roof drains, perimeter details, and other compatible flashing transitions.
Yes, when the specific material is formulated and approved for hot-air welding. Welding compatibility, surface preparation, and installation settings must be confirmed with the manufacturer.
It is generally used for flashing and detail applications rather than as a substitute for reinforced field membrane. Use it as a field sheet only if the product is specifically approved for that purpose and the intended roof assembly.
Yes, if both products are compatible and approved for the same roofing system. Follow the system manufacturer’s instructions for welding, flashing, and transitions.
Thicknesses and dimensions depend on the manufacturer’s product range. Contact the supplier for available thicknesses, roll widths, sheet lengths, and any custom options.
This depends on the formulation and intended application. Select a product designed for the relevant exposure conditions and follow the manufacturer’s recommendations for exposed flashing details.
Depending on the application, accessories may include compatible TPO flashing sheets, prefabricated corners, pipe boots, approved cleaners, termination bars, and other system-specific components.
Customization may be available for dimensions, thicknesses, colors, and packaging. Contact the manufacturer to confirm production capabilities, minimum order quantities, lead times, and shipping arrangements.
