EPDM Roofing Installation Services We Provide

Our comprehensive EPDM installation services address every aspect of rubber membrane roofing for commercial and flat roof applications. Whether you need complete system replacement or new construction installation, our team delivers professional results that protect your property investment.

New EPDM Membrane Installation

Complete EPDM roofing installation begins with thorough substrate preparation and precise membrane positioning to ensure optimal adhesion and weatherproofing performance throughout the system's lifespan. Our technicians follow manufacturer specifications for insulation board placement, vapor barrier installation, and membrane attachment to create seamless waterproof protection.


Each installation includes proper drainage integration and flashing details that prevent water intrusion around roof penetrations, equipment, and building perimeters. Quality control inspections throughout the installation process ensure compliance with building codes and manufacturer requirements for warranty coverage and long-term performance.

EPDM Roof Replacement Services

Existing flat roof replacement involves careful removal of deteriorated roofing materials and assessment of underlying deck conditions before installing new EPDM membrane systems. Our replacement process includes structural repairs when necessary, updated insulation to current energy codes, and improved drainage design that addresses previous performance issues.


Every replacement project receives customized design consideration based on building use, local climate conditions, and owner requirements for energy efficiency and maintenance access. Professional installation techniques ensure proper membrane tensioning, seam integrity, and attachment methods that provide superior wind uplift resistance and long-term durability.

Commercial EPDM System Installation

Large-scale commercial EPDM installation requires specialized equipment and techniques for handling oversized membrane sheets and achieving consistent seam quality across extensive roof areas. Our commercial installation teams coordinate with building operations to minimize business disruption while maintaining safety protocols for multi-story construction and occupied building requirements.


Advanced seam welding techniques create permanent waterproof bonds that exceed industry standards for tensile strength and weather resistance in commercial applications. Project management includes material scheduling, weather monitoring, and progress coordination that keeps commercial installations on schedule and within budget parameters.

EPDM Repair and Maintenance Integration

Preventive maintenance programs help extend EPDM roof life through regular inspections, minor repairs, and protective treatments that address wear before major problems develop. Our maintenance services include seam inspection, membrane cleaning, drain clearing, and equipment mounting verification that keeps roofing systems performing optimally throughout their service life.


Emergency repair capabilities address storm damage, punctures, and unexpected leaks with temporary protection measures and permanent solutions that restore full waterproof integrity. Maintenance documentation supports warranty compliance and helps property owners track system performance for future planning and budget considerations.

FAQs on EPDM Roofing Installation

  • What is EPDM roofing and why is it used for flat roofs?

    EPDM (ethylene propylene diene terpolymer) is a synthetic rubber membrane specifically designed for flat and low-slope commercial roofing applications. This durable material provides excellent waterproofing performance and weather resistance that makes it ideal for buildings where traditional sloped roofing isn't practical or cost-effective.


  • How long does professional EPDM installation take to complete?

    Most EPDM installation projects require 2-5 days depending on roof size, complexity, and weather conditions during the work period. Our installation teams work efficiently while maintaining quality standards that ensure proper membrane placement and seam integrity throughout the installation process.

  • What maintenance does EPDM roofing require after installation?

    EPDM systems need annual inspections, periodic drain cleaning, and prompt repair of any punctures or damage to maintain optimal performance. Regular maintenance programs help identify minor issues before they become major problems and support warranty coverage throughout the system's service life.

  • How does EPDM compare to other flat roofing materials?

    EPDM offers excellent weather resistance and installation versatility compared to TPO or PVC systems, though each material has specific advantages for different applications. Our team evaluates building requirements, budget considerations, and performance expectations to recommend the most appropriate single-ply roofing system for each project.

  • Can EPDM be installed over existing flat roof systems?

    EPDM can sometimes be installed over existing roofing materials if the substrate is structurally sound and properly prepared for membrane installation. Roof assessment determines whether overlay installation is appropriate or if complete removal and replacement provides better long-term value and performance for your specific situation.
