The Best Commercial Roofing Materials & Energy-Saving Systems for California Businesses
When it comes to commercial roofing in California, material selection isn’t just about function—it’s about savings, sustainability, and long-term resilience. With the state’s energy regulations, diverse climates, and rising construction costs, it’s essential for property owners to understand what materials and systems deliver the best return on investment.
In this blog, we’ll break down:
- The Best Commercial Roofing Materials for California’s Climate
- Energy-Efficient Roofing Solutions (Including Solar and Coatings)
- Regional Considerations Across 15 California Cities
1. Best Commercial Roofing Materials for California’s Weather
California’s geography includes coastal fog, desert heat, high winds, and seismic activity. So when you’re selecting commercial roofing materials, you need systems that address your region’s exact needs. Here are the most popular and effective options we install at DK Roofing:
TPO (Thermoplastic Polyolefin)
- Best for: Warm climates like Fontana, Northridge, and Rancho Cucamonga
- Why: White reflective surface lowers building temperatures, saving on HVAC
- Bonus: Seam-welded for leak resistance and excellent for solar mounting
PVC (Polyvinyl Chloride)
- Best for: Chemical plants, restaurants, and facilities with grease exhaust
- Why: Highly resistant to chemicals and fire
- Bonus: Energy-efficient and durable for high-foot-traffic roofs in El Monte or Chino
Modified Bitumen
- Best for: Buildings with frequent foot traffic or rooftop equipment
- Why: Multiple layers provide durability and redundancy
- Bonus: Great for older buildings in Santa Clarita and San Dimas with sloped access
Standing Seam Metal Roofing
- Best for: Warehouses, industrial zones in Commerce, Jurupa Valley
- Why: Ultra-durable, weather-resistant, and recyclable
- Bonus: Ideal for solar panel integration and longevity (40+ years)
EPDM (Rubber Membrane)
- Best for: Budget-conscious flat roofs in mild zones like Garden Grove
- Why: Cost-effective and quick to install
- Bonus: Compatible with green roof or insulation layering systems
2. Energy-Efficient Roofing Options & Coatings
Energy efficiency is more than a trend in California—it’s a requirement under Title 24 and CALGreen standards. DK Roofing specializes in systems that not only meet but exceed these regulations.
Cool Roof Systems
- Reflective surfaces reduce indoor temps by up to 30°F
- Lowers peak cooling demand and saves on electric bills
- Meets or exceeds California Energy Code mandates
Top applications:
- TPO and white PVC systems in Chino, Corona, and Torrance
- Silicone-coated modified bitumen in older retail centers in San Dimas or Culver City
Roof Coatings (Restoration Systems)
Rather than replacing a roof, we can restore it using:
- Acrylic Coatings: Great for UV resistance and ponding mitigation
- Silicone Coatings: Waterproof, chemical-resistant, and durable
Benefits:
- Extends roof life 10–15 years
- Reduces waste and environmental impact
- Eligible for tax deductions as a repair, not a capital improvement
Solar Panel Integration
We provide solar-ready roofing systems for companies looking to offset energy usage and qualify for tax credits.
Common solutions include:
- Ballasted systems on TPO membranes in Northridge and Garden Grove
- Integrated solar with standing seam metal in industrial areas of Commerce and Fontana
- Solar + skylight packages in Corona and Culver City for maximum daylighting
