Spray Foam Roofing
Seamless spray polyurethane roof systems for commercial flat roofs and metal roof retrofits. Self-flashing, reflective topcoat compatible.
Overview
SPF roofing creates a monolithic waterproof and insulating layer in a single application. Self-flashing around penetrations, no seams to leak, and compatible with reflective silicone or acrylic topcoats for cool-roof energy rebates. Pioneer JYYJ-H800 with 2-14 kg/min output handles large commercial rooftops economically.
Recommended JYYJ Machines
JYYJ-H800
$5,200Maximum-throughput hydraulic spray machine with simple button controls. 2-14 kg/min at 36 MPa with 38 kW heating — the highest heating power in the JYYJ line for sub-zero environments. Built for large industrial projects where output volume matters more than touchscreen sophistication.
JYYJ-H-V8T
Contact for quotePioneer's top-tier flagship — the highest-output PLC-controlled spray machine in the JYYJ line. 2-15 kg/min at 36 MPa with 10-inch PLC touchscreen, one-click start/stop operation, and low-temperature protection that prevents incomplete mixing in cold conditions. Flat-mounted booster pump design reduces footprint while maintaining the highest output. Ideal for the most demanding industrial polyurea and polyurethane projects.
JYYJ-H600PK
$5,000Flagship hydraulic spray machine with 10-inch PLC touchscreen and adjustable mixing ratio (1:1~1:2). 2-10 kg/min at 36 MPa for polyurea, high-density foam, and precision-critical applications. Recipe memory and data logging for project documentation. Adjustable ratio handles temperature-driven viscosity shifts and custom material formulations — unique in the JYYJ line.
Recommended Materials
Browse Polyurethane Foam (A + B) →- ● Closed-cell roofing-grade PU (48-50 kg/m³)
- ● Silicone or acrylic reflective topcoat
- ● Embedded mesh for high-wind zones
Why This Setup Works
Monolithic membrane — no seams to fail at penetrations or joints
Self-flashing around HVAC curbs, drains, and parapets
Tapered build-up to slope — solves ponding water without costly re-slope
R-7 per inch — doubles as insulation layer
Technical Considerations
- Wind uplift rating — consult FM / UL classification for region
- Topcoat reflective index — required for cool-roof tax credits
- Ice shield zones — may need additional elastomer layer at eave
- Density for roof: 48-50 kg/m³ minimum (foot traffic durability)
