TPO / PVC
TPO and PVC systems are selected by membrane chemistry, attachment method, and drainage pattern. We design insulation, coverboard, and penetration details to match project performance goals.

TPO
Thermoplastic polyolefin systems where heat performance and seam quality align with energy goals.
PVC
Chemical-resistant PVC profiles for projects with strict chemical exposure or specific substrate needs.
Accessory products
TPO seam tape kit
Seaming accessory
Heat- and climate-rated seam tape used to support clean membrane joins where welding access is limited. It reinforces edge continuity and maintains weather integrity at seams and transitions.
- Flat and low-slope roofs
- TPO systems
- Complex seam routes
- Edge seam continuity
- Transition reinforcement
- Reduced seam risk
- Open-air compatibility
- Service replacement friendly
Drip-edge membrane details
Perimeter detail
Edge detail components to control runoff under overhang and curb conditions. These profiles support stable transition behavior and protect edge terminations over long seasonal cycles.
- Low-slope buildings
- Commercial roofs
- Drain-driven edges
- Edge runoff control
- Reduced water intrusion
- Curb transition control
- Clean perimeter lines
- Weather durability
Manufacturer Options
Soprema
Single-ply systems focused on predictable seams and performance in commercial environments.
Soprema TPO 60
TPO membrane
A high-strength TPO membrane with clear seam strategy and balanced reflectivity. We coordinate this with coverboard and insulation layers for reduced thermal movement and predictable drainage behavior.
- Low-slope commercial
- Thermal performance projects
- Reflective performance
- Reliable seam bonding
- Chemical resistance
- Efficient drainage integration
- Commercial reliability
Carlisle
PVC membrane systems with adaptable attachment methods and detail-focused engineering.
Carlisle Sure-Seal PVC
PVC membrane
A PVC membrane tuned for resilient seams and aggressive chemical resilience. When paired with compatible drains and fastener layout, it supports efficient maintenance cycles and cleaner transitions.
- Commercial facilities
- Exposure-rich roofs
- Chemical resistance
- Consistent seam profile
- Adaptive termination
- Drain-ready layouts
- Commercial compatibility
California availability
Availability varies by supplier and branch location. We source materials through California distributors based on your project needs.
Frequently Asked Questions
TPO and PVC look different to install—does it matter?
Yes. The same site can require different seam methods, seaming tools, and compatibility checks depending on membrane chemistry.
Do all single-ply systems need drains and scuppers?
All low-slope roofs need engineered drainage. The drain strategy is chosen by slope, rainfall intensity, and rooftop utilities.
Is mechanical attachment stronger than fully bonded?
Both systems perform when designed correctly. We choose attachment based on roof deck, insulation profile, and service access requirements.
