Our Rubber Roof Installation Process

Our certified installers follow manufacturer specifications and industry best practices for every EPDM installation.

1. Preparing the Roof Surface

We begin by cleaning the existing roof surface, removing all debris, dirt, and loose materials. Any damaged decking or insulation must be replaced before proceeding. The surface needs to be completely dry and smooth.


We install a new layer of roof insulation board, securing it with appropriate fasteners to meet local building codes. We inspect for proper drainage slopes and make adjustments as needed. The perimeter edges are carefully prepared with new drip edge and termination bars.

2. EPDM Membrane Installation Technique

We roll out the EPDM membrane and allow it to relax for 30 minutes before securing. This step prevents future wrinkles or bubbles in the rubber surface. Our team applies bonding adhesive evenly to both the substrate and membrane underside.


Proper adhesive coverage is critical for a secure bond. We position the membrane, working from the center outward to eliminate air pockets. Each seam is cleaned with special solvent and sealed with seam tape.

3. Finishing Touches and Weatherproofing

All roof penetrations get fitted with pre-molded pipe boots and sealed thoroughly. We install new flashings around vents, chimneys, and other protrusions. Special attention goes to corner details where leaks commonly occur. Each corner receives reinforced membrane patches and sealant.


We verify all seams are properly bonded and apply lap sealant for extra protection. New scuppers or drains are installed as needed for optimal water drainage. Final inspection includes water testing to confirm complete waterproofing of the system

What Is Rubber Roofing?

Rubber roofing consists of synthetic rubber membranes, primarily EPDM (Ethylene Propylene Diene Monomer). It is designed specifically for protecting buildings. We install these membranes in large sheets that create a watertight seal across your roof's surface.


These membranes typically measure between 45 and 60 millimeters in thickness, providing robust protection against weather elements. Our rubber roofing systems  can be either fully adhered or mechanically fastened, depending on your specific needs and roof structure.


Benefits of Rubber Roofing



These roofs excel in Portland's rainy climate thanks to their superior waterproofing capabilities. The seamless installation prevents water infiltration common with traditional roofing materials. The dark surface absorbs heat in winter, while reflective coatings can be added to reduce summer cooling costs. Installation costs remain competitive due to:


  • Quick installation process
  • Lightweight materials
  • Minimal maintenance requirements
  • Lower labor costs

Routine Rubber Roof Maintenance

We recommend inspecting your rubber roof at least twice a year, ideally in spring and fall. Remove any debris, leaves, or branches that could trap moisture or damage the surface. Clean the roof surface with a soft brush and mild detergent. Avoid harsh chemicals or pressure washers that might damage the rubber material.


Check all seams and edges for signs of separation or wear. Look for any loose fasteners or flashings that need attention. Watch for signs of ponding water, which can lead to premature aging and leaks. Good drainage is essential for rubber roof longevity.


Small tears or punctures can be fixed with rubber roof patches and specialized adhesive. We use manufacturer-approved materials for all repairs. Common repair needs include:


  • Seam separation
  • Puncture holes
  • Weather damage
  • Flashing repairs

When to Consider Roof Replacement

A well-maintained rubber roof typically lasts 20-30 years. Signs that indicate replacement may be needed:


  • Multiple recurring leaks
  • Widespread cracking or splitting
  • Extensive weather damage
  • Material shrinkage
  • Age exceeding 25 years


We perform a thorough inspection to determine if repair or replacement is more cost-effective for your situation. Early replacement often prevents interior damage and saves money compared to multiple repairs on an aging roof.

DIY vs Professional Rubber Roof Installation

While DIY rubber roofing might seem cost-effective, professional installation offers significant advantages. We use specialized tools and techniques that ensure proper adhesion and sealing. Professional installation prevents common issues like improper seaming and inadequate substrate preparation. Our team's expertise helps avoid costly mistakes that often plague DIY attempts.


The complexity of rubber roof installation requires precise measurements and careful handling of materials. We manage these challenges daily, ensuring your roof meets all quality standards. Key benefits of professional installation:



  • Expert material selection
  • Proper ventilation setup
  • Professional-grade tools
  • Warranty protection
  • Code compliance
