Our Commercial Roofing Services
TPO (Thermoplastic Polyolefin) Roofing
We install TPO roofing systems using precision heat-welding technology for seamless, watertight bonds that last 25 to 30 years. Our energy-efficient roofs reflect up to 87% of UV rays, reducing cooling costs and extending roof life. Class A fire-rated membranes provide exceptional durability, flexibility, and protection for all commercial buildings.
Built-Up Roofing (BUR)
We construct BUR systems with multiple layers of bitumen and reinforcing fabrics to create waterproof, high-strength roofs. These roofs last 20 to 30 years and resist foot traffic and harsh weather. Hot-mop and cold-apply techniques ensure precise adhesion and a smooth, durable finish trusted by 95% of industrial clients.
Metal Roofing Systems
We provide premium metal roofing solutions with galvanized steel, aluminum, and standing seam panels engineered to last 40 to 50 years with minimal maintenance. Class A fire-rated roofs withstand winds up to 140 mph and offer modern aesthetics. Mechanical seaming and concealed fasteners ensure maximum weather resistance and long-term performance.
Roof Coatings and Restoration
We restore aging roofs with elastomeric and silicone coatings that extend service life by 10 to 15 years and improve energy efficiency. Our coatings provide up to 90% solar reflectivity, lowering rooftop temperatures and reducing energy costs. Spray and roll-on techniques create a seamless, waterproof barrier ideal for revitalizing existing commercial roofs.
Flat Roof Repair and Maintenance
We perform flat roof repair and maintenance to prevent leaks and structural damage. Infrared moisture scanning and advanced sealing techniques identify and fix problem areas early, extending roof life by up to 40%. Scheduled maintenance programs keep commercial roofs performing like new year-round.
Single-Ply PVC Roofing
We install PVC roofing systems offering flexibility, chemical resistance, and long-term durability. Class A fire-rated roofs last over 25 years and resist grease, chemicals, and UV degradation. Mechanically fastened and fully adhered installations ensure a tight, reliable seal that keeps properties protected.
Types of Materials We Use for Commercial Roofing
TPO (Thermoplastic Polyolefin) Membrane
We install TPO membranes for their superior UV reflectivity, reducing heat absorption and energy costs. Over 60 percent of Southern California commercial roofs now use TPO for its durability and long-term performance. Our heat-welded installation creates a watertight, flexible roof that withstands the region’s weather conditions.
PVC (Polyvinyl Chloride) Roofing Material
We use PVC roofing for its chemical, grease, and fire resistance, making it ideal for restaurants, warehouses, and industrial facilities. This material maintains a Class A fire rating and lasts more than 25 years with minimal upkeep. Fully adhered or mechanically fastened installation ensures maximum strength and leak protection.
EPDM (Ethylene Propylene Diene Monomer) Rubber Roofing
We apply EPDM rubber roofing for its flexibility and proven resistance to extreme weather. This material withstands heat waves and cool nights while maintaining performance for up to 30 years. Fully adhered installation produces a seamless, low-maintenance surface suitable for large commercial roofs.
Modified Bitumen Roofing
We recommend Modified Bitumen roofing for clients who require a robust, multi-layered system that endures heavy foot traffic and temperature fluctuations. This material offers a 20–25 year lifespan and performs reliably under California conditions. Torch-down or cold-adhesive application ensures superior adhesion and waterproofing.
Metal Roofing Panels
We use galvanized steel and aluminum panels that deliver exceptional longevity, with service life exceeding 40 years in coastal environments. Metal roofs provide Class A fire resistance and withstand winds up to 140 miles per hour. Standing seam and concealed fastener systems deliver a sleek, weather-tight finish.
Silicone and Elastomeric Roof Coatings
We apply silicone and elastomeric coatings to extend roof life by 10–15 years while improving energy efficiency. These coatings reflect up to 90 percent of sunlight, reducing cooling costs for commercial buildings. Spray or roll-on application creates a seamless, waterproof layer compatible with all roof types.
What Commercial Roof Issues
We Solve
Roof Leaks and Water Intrusion
We detect and repair roof leaks, a leading cause of commercial roof failures. Over 70% of roofing problems begin with minor leaks that escalate if not addressed. Our technicians use infrared moisture scanning and precision sealing to identify and eliminate leaks before they cause costly interior damage, reinforcing vulnerable areas to ensure complete waterproof protection.
Ponding Water on Flat Roofs
We eliminate ponding water on flat or low-slope roofs, a common issue in Orange County. Nearly 40% of maintenance calls involve drainage problems that accelerate membrane wear and compromise structural integrity. We regrade roof surfaces, optimize drainage systems, and apply reflective coatings to maintain proper water runoff and prevent future damage.
Roof Membrane Damage and Blistering
We repair membrane blisters, cracks, and punctures caused by UV exposure, foot traffic, and temperature fluctuations. Orange County’s intense sun can cause membranes to expand and contract, leading to early deterioration. Our team uses heat-welded patches, reinforced membranes, and UV-resistant coatings to restore integrity and extend roof life by up to 15 years.
Aging and Deteriorated Roof Systems
We restore aging commercial roofs that have lost protective coatings or performance over time. Many property owners choose restoration over replacement to save costs while gaining long-term protection. Our specialists apply silicone and elastomeric roof coatings to seal, insulate, and protect, transforming aging roofs into durable, energy-efficient systems built to last.
