Commercial Benefits
White reflective TPO reduces cooling load by up to 30% compared to dark BUR or modified bitumen.
GAF, Carlisle SynTec, and Firestone NDL warranties available with certified installation.
Hot-air welded seams are stronger than the membrane itself — zero adhesive failure points.
Meets California cool-roof mandates and qualifies for utility rebates on retrofit projects.
60, 80, or 90 mil options handle rooftop HVAC traffic, grease, and industrial exposure.
Lower installed cost than PVC or EPDM with equal-or-better lifecycle economics.
Energy Savings
A white TPO roof over insulated cover board can drop rooftop surface temps by 50-70°F versus a dark BUR or modified bitumen roof. For a 40,000 SF Central Valley facility that translates to $6,000-$9,000 in annual cooling savings and 7-9 year payback on the reflective upgrade alone.
Installation Process
Digital moisture scan, core cuts, and structural load analysis. Full report with photos and infrared.
TPO thickness, insulation R-value, attachment method, and wind uplift zones per FM Global or ASCE-7.
Full tear-off to deck or 2-layer maximum recover with cover board — matched to existing conditions.
Poly-iso insulation, cover board, then TPO membrane mechanically attached or fully adhered.
All seams robot-welded and hand-welded at penetrations. Every flashing, curb, and drain sealed.
Third-party manufacturer inspection issues the NDL warranty and hands off maintenance schedule.

Your commercial roof does more than cover your building. It protects your employees, equipment, inventory, and daily operations. When a roofing system begins to fail, it can lead to water damage, energy loss, and costly interruptions. At Alcon's Roofing Inc, we provide dependable commercial roofing in California for office buildings, retail spaces, warehouses, industrial facilities, and other commercial properties throughout Fresno and the Central Valley. With more than 35 years of experience, we install roofing systems that are designed to perform well in California's climate while meeting the needs of your business.
Many commercial buildings have flat or low-slope roofs that require materials built for durability and weather resistance. TPO roofing in California has become a popular option because it offers excellent performance, reflects heat, and requires minimal maintenance compared to many traditional roofing systems.
TPO membranes create a strong, watertight surface that helps reduce the risk of leaks while improving energy efficiency. They are well suited for new construction, roof replacements, and building owners looking for a dependable roofing system with long-term value. Our team will evaluate your property and recommend the roofing solution that best fits your building and budget.
Installing a commercial roof requires careful planning and attention to detail. Every project begins with an inspection of your existing roof or building plans. We assess drainage, insulation, roof condition, and structural requirements before recommending the best approach.
Whether your property requires commercial flat roofing in California or a complete roof replacement, our experienced crew follows proven installation methods to deliver reliable results. We install every roofing component with precision, paying close attention to seams, flashing, drainage areas, and roof penetrations. Before completing the project, we perform a detailed inspection to ensure your new roofing system is ready to protect your business for years to come.
Alcon's Roofing Inc has been serving Fresno and the Central Valley for more than three decades.
