Our Installation Process

At Portland Roofing Center, we implement a precise, systematic approach to EPDM roof installation that maximizes durability and performance. Our proven process ensures your rubber membrane roofing system delivers optimal protection for your commercial building.

Initial Roof Inspection and Consultation

We begin with a thorough assessment of your existing roof structure and conditions. Our certified inspectors measure the roof dimensions and examine the substrate, drainage systems, and potential obstacles.

We document any existing damage or structural concerns that need addressing before installation. This helps prevent future complications.


A detailed project plan is created, including material requirements, timeline, and specific installation considerations for your building.


We provide transparent pricing based on your roof's square footage, typically ranging from $5-8 per square foot for materials and professional installation.

Preparation and Safety Measures

We clear the roof surface of debris and repair any damaged areas of the substrate. Proper preparation is critical for adhesion and longevity.


Our team sets up safety equipment including fall protection systems and warning lines to ensure OSHA compliance throughout the project. We carefully stage materials and equipment to maximize efficiency while protecting your property.

The Installation Technique

We unroll and position the EPDM membrane sheets with proper overlap spacing. Each section is allowed to relax and expand before securing.


Our specialized adhesive application ensures strong bonding between the membrane and substrate. We use rollers to eliminate air pockets and create a tight seal.


All seams are cleaned and primed before applying seam tape for watertight connections. We pay special attention to corners, edges, and penetrations.

Why Choose EPDM Roofing

EPDM roofs deliver significant value through their competitive pricing and straightforward installation process. The material costs less than many alternative roofing options while maintaining high performance standards.


These roofs resist damage from UV rays and extreme temperatures, making them ideal for diverse climate conditions. The synthetic rubber composition provides natural flexibility, allowing the material to expand and contract without cracking.


We've found EPDM to be particularly resistant to fire and wind damage. The material also maintains its integrity during heavy rainfall and can effectively prevent water penetration.

How Durable is EPDM Material?

A properly installed EPDM roof typically lasts 25 to 30 years with regular maintenance. The material's thickness, typically available in 45 and 60 mil options, contributes to its long-term performance.


The membrane remains stable and functional through seasonal temperature changes. Its UV-resistant properties prevent premature aging and deterioration.


Regular inspections twice per year help maintain the roof's integrity. Professional maintenance can identify and address potential issues before they develop into serious problems.
