San Diego EPDM Roofing Services - Call (619) 483-1917

EPDM (Ethylene Propylene Diene Monomer) roofing is a highly durable synthetic rubber roofing membrane widely used in low-slope buildings. Composed primarily of ethylene and propylene derived from oil and natural gas, EPDM is known for its exceptional weather resistance and flexibility.

Developed in the 1960s, EPDM roofing has evolved significantly over the decades. Advances in manufacturing and installation techniques have enhanced its performance and longevity. Available in both black and white, EPDM membranes typically come in thicknesses ranging from 45 mils to 90 mils, providing various options based on durability requirements.

EPDM roofing is commonly used for commercial and industrial buildings with low-slope or flat roofs. Its flexibility and durability make it suitable for a wide range of applications, including warehouses, office buildings, and retail centers. Its ability to withstand extreme weather conditions and UV exposure makes it a preferred choice for large-scale commercial projects.

Benefits of EPDM Roofing

Durability and Longevity

EPDM roofing is renowned for its durability, often lasting 20 to 30 years or more with proper maintenance. Its robust nature makes it resistant to tears, punctures, and impact damage, ensuring a long-lasting roofing solution for commercial buildings.

Weather Resistance

EPDM is highly resistant to extreme weather conditions, including UV radiation, hail, and temperature fluctuations. Its ability to withstand harsh climates without cracking or deteriorating makes it an ideal choice for diverse environments.

Energy Efficiency

EPDM roofing contributes to energy efficiency, particularly with white EPDM membranes that reflect sunlight and reduce cooling costs. This reflective property helps maintain cooler building temperatures, lowering energy consumption and HVAC expenses.


EPDM roofing is cost-effective both in terms of initial installation and long-term maintenance. Its relatively low material and labor costs, combined with minimal maintenance requirements, provide significant savings over the roof’s lifespan.

Flexibility and Versatility

EPDM’s flexibility allows it to accommodate various roof shapes and sizes, making it suitable for a wide range of commercial applications. Its ability to stretch and conform to building movements without compromising integrity ensures reliable performance across different structural designs.

Types of EPDM Roofing Systems

Black EPDM

Black EPDM is the most common type of EPDM roofing membrane. Known for its UV resistance, it effectively withstands sunlight and other weather elements. Its dark color helps it absorb heat, which can be advantageous in colder climates by reducing heating costs during winter months.

White EPDM

White EPDM offers all the benefits of traditional black EPDM but with enhanced reflective properties. Its white surface reflects sunlight, significantly reducing cooling costs in warmer climates. This makes it an excellent choice for energy efficiency and sustainability in commercial buildings.

Reinforced vs. Non-Reinforced EPDM

Reinforced EPDM includes an additional layer of scrim, providing extra strength and resistance to punctures and tears. This type is ideal for roofs with high foot traffic or where durability is paramount. Non-reinforced EPDM, while still durable, is more flexible and easier to install, making it suitable for less demanding applications. Both types offer robust performance, with the choice depending on specific roofing needs and conditions.

Our San Diego EPDM Roofing Installation Process

Initial Consultation and Assessment

Our process begins with a comprehensive consultation to understand your roofing needs. We conduct a thorough site assessment to evaluate the existing roof structure, identify potential challenges, and determine the best EPDM roofing solution for your commercial building.

Site Preparation

Proper site preparation is crucial for a successful installation. This involves cleaning the roof surface, repairing any damaged areas, and ensuring proper drainage. We also remove any debris and inspect the substrate to create a smooth, clean base for the EPDM membrane.

Installing the Insulation

Installing high-quality insulation is the next step. This layer helps enhance the building’s energy efficiency and provides a solid foundation for the EPDM membrane. We use materials that offer superior thermal performance, ensuring optimal energy savings and comfort.

Laying the EPDM Membrane

We lay the EPDM membrane using one of three methods: fully adhered, mechanically attached, or ballasted, depending on the specific requirements of your roof. Each method has its advantages, and we choose the one that best suits your building’s needs and conditions.

Quality Assurance

Our commitment to quality doesn’t end with installation. We conduct thorough inspections and testing to ensure the EPDM roof meets our high standards. This includes checking for proper adhesion, sealing, and overall integrity, guaranteeing a long-lasting, reliable roofing system for your commercial property.

Cost of EPDM Roofing in San Diego

Factors Influencing Costs

The cost of EPDM roofing in San Diego depends on several factors, including roof size, complexity, material thickness, and installation method. Additional elements like insulation, labor, and the condition of the existing roof can also impact the overall cost.

Cost Comparison with Other Roofing Materials

Compared to other commercial roofing options like TPO, PVC, and modified bitumen, EPDM is generally more affordable in terms of both material and installation costs. Its cost-effectiveness makes it a popular choice for businesses looking for a durable and budget-friendly roofing solution.

Long-Term Savings
