Our Covina Commercial Roofing Services
TPO Roofing Systems
We install thermoplastic polyolefin roofs built for top energy efficiency and UV protection, reflecting up to 87% of solar heat. Our heat-welded seams create a watertight barrier that lasts 20 to 30 years while cutting cooling costs by as much as 35%. We use mechanically fastened or fully adhered methods to ensure maximum strength and a Class A fire rating for complete safety.
PVC Roofing Systems
We install Polyvinyl Chloride roofing for durability, chemical resistance, and flexibility, ideal for restaurants, factories, and industrial facilities. Reinforced membranes and heat-welded seams deliver 25 to 30 years of dependable performance against grease, oil, and harsh weather. Our fully adhered system guarantees superior wind resistance and a Class A fire rating.
EPDM Rubber Roofing
We install EPDM single-ply rubber membranes that handle extreme temperatures, ozone, and UV exposure for up to 40 years. The seamless design ensures watertight protection with minimal maintenance, making it ideal for large commercial roofs. We offer ballasted or fully adhered systems that provide flexible, long-term performance.
Modified Bitumen Roofing
We install modified bitumen systems that combine asphalt and rubber for maximum strength and flexibility. This roofing lasts 20 to 25 years and resists punctures, tears, and water intrusion even in changing weather. We apply it using torch-down or cold-adhesive techniques, creating a seamless, durable, and Class A fire-rated surface.
Built-Up Roofing (BUR)
We install built-up roofing systems, known as tar and gravel roofs, that provide multi-layer waterproofing and insulation lasting 25 to 30 years. Each layer of bitumen and reinforcing felt increases durability, making it perfect for high-traffic commercial roofs. We apply it using hot or cold methods to achieve a dense surface with excellent UV and fire protection.
Metal Roofing Systems
We install commercial-grade metal roofs that last 40 to 60 years with minimal maintenance. Our standing seam and R-panel systems deliver superior wind resistance, energy savings, and a Class A fire rating. Precision fastening and concealed clips ensure leak-free performance with a modern, professional look.
Types of Materials We Use Commercial Roofing
TPO Roofing (Thermoplastic Polyolefin)
We use TPO roofing for its outstanding energy efficiency and cost savings. Its reflective surface reduces cooling costs by up to 35%, making it one of the most sustainable choices for commercial roofs. TPO performs exceptionally well under California’s intense sunlight and offers long-term protection with minimal maintenance.
EPDM Roofing (Ethylene Propylene Diene Monomer)
We install EPDM roofing for its proven flexibility and resistance to heat, UV rays, and weather fluctuations. It performs exceptionally well on flat or low-slope roofs and lasts over 25 years with minimal upkeep. EPDM remains a preferred option for property owners seeking durability and consistent performance in changing weather conditions.
Modified Bitumen Roofing
We use modified bitumen systems for their layered strength and superior resistance to leaks, tears, and UV exposure. This material is ideal for warehouses and office buildings that need dependable waterproofing and long-lasting performance. It offers a balance of affordability and endurance that fits the needs of most commercial applications.
Commercial Roof Issues We Solve
Roof Leaks and Water Ponding
We eliminate roof leaks and standing water, issues that impact nearly 40% of commercial buildings in Covina annually. Standing water weakens membranes, promotes mold growth, and can cause costly interior damage. We deploy infrared leak detection and design custom drainage solutions to remove water accumulation and safeguard your roof against future leaks.
Poor Installation and Aging Roofing Systems
We correct issues resulting from improper installation or aged materials, which account for nearly 25% of roof failures in the area. Older roofs often show seam separation, insulation problems, and energy inefficiency. We provide complete roof retrofits or replacements with modern materials that meet Title 24 energy efficiency standards and deliver decades of reliable performance.
Membrane Cracking, Blistering, and UV Damages
We repair cracked, blistered, or UV-damaged membranes caused by Covina’s intense sun exposure and temperature fluctuations. One in three flat commercial roofs in Southern California develops membrane damage within a decade. We restore membranes using reinforced patching, high-performance sealants, and reflective coatings to extend roof life by up to 15 years.
Storm, Wind, and Debris Damage
We repair roofs compromised by storm, wind, and debris, increasingly common challenges in Covina due to seasonal gusts. High winds lift seams, dislodge flashing, and threaten structural integrity. Our team reinforces vulnerable areas using impact-resistant membranes, high-strength fasteners, and protective coatings to restore strength and prevent future damage.
How Much Does Commercial Roof Replacement Cost in Covina, CA?
Business owners in Covina, CA, can expect commercial roof replacement costs to range from $6 to $18 per square foot, depending on the roofing system, building size, and installation complexity. Popular flat roofing options like TPO, PVC, and EPDM typically cost $7–$15 per square foot and offer excellent energy efficiency, weather resistance, and long-lasting performance, making them ideal for Covina’s sunny climate. For properties needing extra durability or aesthetic appeal, premium systems such as modified bitumen, built-up roofing (BUR), and standing seam metal roofs range from $16–$22 per square foot and provide enhanced insulation and fire resistance.
On average, materials make up 45–50% of total costs, while labor, tear-off, and installation account for 30–40%. Additional factors such as roof accessibility, structural preparation, ventilation upgrades, and compliance with local building codes can influence the final estimate.
