4,200m² Commercial Roof SPF System · Almaty

What Pioneer Delivered

Not just a machine — a matched system, a trained crew on site, and after-sales backing end to end.

• On-site roof survey — moisture scan, drain mapping and detailing of all 32 penetrations before spraying — so the new SPF bonds over a sound deck instead of trapping old leaks.
• A single-source system — the JYYJ-H800 machine, the closed-cell foam and the reflective silicone topcoat matched and warranted together, not waterproofing, insulation and equipment sourced from three suppliers who blame each other.
• A spray crew trained for flat-roof self-flashing and topcoat consistency — the hard part of SPF roofing is even thickness and clean penetration detailing, and we own it.
• Flood-test QA and a phasing plan built around the warehouse's operation — 4,200 m² re-roofed in 11 working days with no full tear-off and no shutdown of the logistics floor below.
• Ongoing remote support for topcoat re-coat scheduling and re-order of the exact matched foam and silicone — so future roof areas or maintenance are a phone call, not a new project.

Execution Process

1. 1 · Roof Survey & Surface Prep

   The existing torch-on membrane is inspected, wet insulation cut out, and the substrate cleaned and dried so the spray foam bonds over a sound deck. Drains and the 32 penetrations are mapped before any application.

2. 2 · Setup & Self-Flashing

   The JYYJ-H800 is staged on the roof and set to 36 MPa, with proportioner and hose temperatures dialed in for 48 kg/m3 closed-cell foam. Curbs, drains and the 32 penetrations are pre-detailed so the foam self-flashes each one monolithically.

3. 3 · SPF Spray Application

   Spray 60 mm of closed-cell SPF at 48 kg/m3 with the JYYJ-H800 at 36 MPa, building a seamless self-flashed membrane that drains to positive slope and eliminates ponding water. A 3-person crew sustains roughly 380 m2 per day.

4. 4 · Silicone Topcoat & Return

   Once the foam cures, a 30 mil reflective silicone topcoat is sprayed over the full field for UV protection and cool-roof reflectivity. The roof is flood-checked for drainage and handed back ready for service with a continuous R-30+ envelope.
