Single-Ply Roofing Systems
Why PVC & TPO Are the Right Choice for Low-Slope Roofs
Low-slope and flat commercial roofs deal with conditions that traditional roofing systems are not built to handle.
PVC and TPO single-ply membranes have become the industry standard for these applications because they are designed for those exact conditions.
Unlike built-up roofing or modified bitumen systems that rely on multiple layers and open-flame application, PVC and TPO systems install as a single continuous membrane with heat-welded seams.
Those seams create a watertight bond that is stronger than the membrane itself, resulting in a clean, durable surface that performs reliably across different building types, climates, and rooftop conditions.
System Type
PVC
Polyvinyl Chloride Single-Ply Membrane
- Outstanding chemical and grease resistance, ideal for restaurants, kitchens, and industrial rooftops
- Class A fire rated, meets demanding building code requirements
- Heat-welded seams create a monolithic, watertight membrane with no adhesive failure risk
- Highly flexible, remains pliable in cold temperatures and resists cracking
- Excellent dimensional stability over the full life of the system
- Compatible with prefabricated PVC flashings for faster, cleaner installations
- Available with 20-year standard and 30-year edge-to-edge manufacturer warranties
System Type
TPO
Thermoplastic Polyolefin Single-Ply Membrane
- Highly reflective white surface, Energy Star rated and California Title 24 compliant
- Excellent UV and ozone resistance in high-sun climates like San Diego
- Cost-effective, one of the most competitive single-ply options available today
- Resistant to puncture, tears, and impact in high-traffic commercial applications
- Heat-welded seams provide the same monolithic bond as PVC without solvent adhesives
- Compatible with prefabricated TPO flashings for faster installation timelines
- Available with 20-year standard and 30-year edge-to-edge manufacturer warranties

Rooftop Ventilation
Gravity & Turbine Vents
Flash-Tech Mfg supplies both gravity and wind-driven turbine ventilators engineered for single-ply flat and low-slope roof applications. Properly sized and flashed ventilation is essential for membrane longevity. Our prefabricated vent flashings ensure a watertight, code-compliant installation every time.
Low-Slope Performance
Built for the Demands of Flat Roofing.
Low-slope roofs are uniquely vulnerable to standing water, thermal expansion, rooftop foot traffic, and UV exposure. A roofing system that works on a steep-slope application will fail rapidly in these conditions.
PVC and TPO single-ply membranes are engineered from the ground up for exactly these stresses. Their flexibility allows them to move with the building through thermal cycling without cracking or delaminating. Their seamless welded surface eliminates the lap joints and exposed fasteners that are the primary failure points in older systems.
The Flash-Tech Advantage
The Accessories Are as Important as the Membrane.
Even the best single-ply membrane is only as good as the detailing around its penetrations, edges, and transitions. Roof flashings at curbs, pipes, drains, walls, and perimeters are the most critical and most labor-intensive part of any single-ply installation.
That’s exactly where Flash-Tech Mfg delivers maximum value to roofing contractors. Our prefabricated PVC and TPO flashings eliminate the time-consuming task of field-fabricating these details, turning a multi-step process into a fast, consistent installation using precisely built components.
Prefabricated Flashings
Save Time.
Save Money.
Every Job.
Field fabricating flashings on a rooftop is one of the most time-consuming and weather-dependent parts of any flat roof installation. Every pipe boot cut, every corner formed, and every curb wrap measured and welded on-site adds labor hours, and labor is your most expensive cost on the job.
Flash-Tech prefabricated flashings are built to exact specifications in a controlled shop environment, quality-checked before they leave El Cajon, and delivered ready for installation. No field cutting. No on-site fabrication. Just fast, consistent, professional results.
Dramatically Reduced Labor Hours
Shop-built components arrive ready to install, cutting down flashing time on every project. Less time fabricating means your crew keeps moving and your job stays on budget.
Consistent Quality, Every Time
Fabricated in a controlled shop environment for accurate, repeatable results. Everything fits the way it should, without the rework and callbacks that come from field-built pieces.
Lower Material Waste
Shop fabrication uses material more efficiently than cutting and forming on-site. Less scrap, less waste, and better cost control across every job.
Warranty-Compliant Details
Built to meet manufacturer requirements for single-ply systems, so your installs stay compliant and your customer stays covered.
Faster Project Completion
When flashings show up ready to go, installs move faster. Less time on the roof means quicker turnaround and more jobs completed.
Energy Efficiency
Long Service Life
Code Compliance
Fast Installation
