You get durable, energy-efficient membranes, honest recommendations, and hands-on oversight from start to finish, all backed by decades of local experience.
Improve Energy Efficiency on
Flat Commercial Roofs
PVC and TPO roofing are single-ply membrane systems commonly used on commercial buildings with flat or low-slope roofs. These roofs are installed in large sheets and mechanically fastened, adhered, or heat-welded at the seams to create a watertight surface. PVC is known for its chemical resistance, while TPO is valued for strong seams, heat reflectivity, and cost efficiency. Both are lightweight, durable, and designed to handle heavy sun exposure.
For commercial properties in Southern California, PVC and TPO roofing are ideal because they help improve energy efficiency and meet Title 24 requirements. Their reflective surfaces reduce heat absorption, lowering interior temperatures and cooling costs. When installed correctly, these systems provide long-lasting protection, minimal maintenance needs, and reliable performance for offices, retail spaces, warehouses, and multi-unit buildings.
How We Handle Commercial PVC & TPO Roofing
We start with a thorough, in-person roof inspection, during which we assess the existing membrane or roof assembly, insulation condition, deck type, and drainage performance. We then identify ponding water, compromised seams, saturated insulation, and structural concerns around penetrations, skylights, HVAC curbs, parapet walls, and edge details. Based on our findings, we determine whether a full tear-off or a Title 24-compliant recovery system makes sense, and we recommend the appropriate measures.
Once installation begins, we prep the substrate, install a vapor barrier when required, and place tapered polyiso insulation to improve slope and water flow toward drains. We then mechanically fasten or fully adhere the PVC or TPO membrane, then heat-weld all seams and probe them for consistency. We carefully detail flashings, terminations, and penetrations, then complete a final inspection to confirm watertight performance and code compliance.
Benefits of Commercial PVC & TPO Roofing
Improve Energy Efficiency and Reflect Heat
PVC and TPO membranes feature highly reflective surfaces that reduce heat absorption on flat and low-slope roofs. This helps keep interior spaces cooler, lowers HVAC workload, and can reduce overall energy costs. In Southern California, this reflectivity also supports Title 24 compliance and improves long-term efficiency for commercial buildings.
Deliver Strong, Watertight Seam Performance
One of the biggest advantages of PVC and TPO systems is heat-welded seams. These seams fuse the membrane together, creating a continuous, watertight layer that resists leaks far better than traditional roofing systems. Properly welded seams hold up against ponding water, wind uplift, and daily expansion and contraction.
Provide Durability With Low Ongoing Maintenance
PVC and TPO roofs are built to handle UV exposure, temperature swings, and rooftop foot traffic common on commercial properties. They resist cracking, puncturing, and chemical exposure, especially on buildings with grease vents or HVAC equipment. With routine inspections, these systems offer long service life and predictable maintenance costs.
Support Faster Installation and Lighter Roof Loads
Because PVC and TPO membranes are lightweight and installed in wide sheets, they allow for faster installation compared to many built-up roofing systems. This reduces labor time and minimizes disruption to your business. Their lighter weight also places less stress on the building structure, making them ideal for retrofits and replacements.
