What Is Commercial Roofing?

Commercial roofing covers the design, installation, repair, and maintenance of roofing systems on non-residential buildings. Unlike steep-slope residential roofs, commercial roofs are typically flat or low-slope and require different materials, drainage systems, and installation techniques. At South Bay Roofing CO, we focus on systems that maximize durability, energy efficiency, and weather resistance for San Jose's unique microclimate.

Commercial Roofing Materials We Use

Each material has specific advantages depending on your building's use, budget, and location within San Jose.

TPO (Thermoplastic Polyolefin) — Energy-efficient, reflective membrane. Cost: $5.50–$8.00/sq.ft. installed. Lifespan: 20–30 years.
PVC (Polyvinyl Chloride) — Excellent chemical resistance, ideal for restaurants or industrial spaces. Cost: $6.00–$9.00/sq.ft. Lifespan: 20–30 years.
EPDM (Ethylene Propylene Diene Monomer) — Durable rubber membrane, great for low-slope. Cost: $4.50–$7.00/sq.ft. Lifespan: 25–35 years.
Modified Bitumen — Multi-ply asphalt-based system. Cost: $5.00–$7.50/sq.ft. Lifespan: 15–25 years.
Metal Roofing — Standing seam or corrugated. Cost: $7.00–$12.00/sq.ft. Lifespan: 40–60 years.
Built-Up Roofing (BUR) — Traditional tar and gravel. Cost: $5.50–$8.00/sq.ft. Lifespan: 20–30 years.

Cost Ranges for Commercial Roofing in San Jose

San Jose commercial roof replacement typically runs $8,000–$30,000+ depending on square footage, material choice, and roof complexity. For a 2,000 sq.ft. flat roof with TPO, expect $11,000–$16,000. Add $1,500–$3,500 for tear-off of existing layers. We provide free, itemized estimates with no surprises.

Signs Your Commercial Roof Needs Attention

San Jose's temperature swings and occasional heavy rain accelerate wear. Look for ponding water, cracked membrane, interior leaks, visible sagging, or high energy bills. If your roof is over 15 years old, schedule an inspection — many issues start small but escalate quickly.

Our Step-by-Step Commercial Roofing Process

Free Inspection & Estimate — We assess your roof, take measurements, and discuss material options. We check for moisture, structural issues, and drainage problems.

Preparation & Tear-Off — We protect your property, remove old roofing, and inspect the deck. For re-roofs, we may overlay if code allows.

Insurance & Warranty Information

We carry full liability and workers' compensation insurance. All materials come with manufacturer warranties (20–30 years typical). Our workmanship warranty covers installation for 5–10 years. We help you file insurance claims for storm damage — just call us first.

San Jose Climate Considerations

San Jose's Mediterranean climate means hot, dry summers and cool, wet winters. UV radiation degrades some membranes faster — TPO and PVC reflect heat well. Winter rain requires proper drainage to prevent ponding. Our team selects materials and designs drainage specifically for local weather patterns.
