EPDM (Ethylene Propylene Diene Monomer)

EPDM ROOFING SYSTEMS

Commercial & Industrial EPDM Roofing Across Colorado, Wyoming, Kansas & New Mexico

EPDM (Ethylene Propylene Diene Monomer) is one of the longest-lasting and most reliable commercial roofing systems in the industry. Known for its exceptional flexibility, weather resistance, and proven performance in harsh climates, EPDM is a top choice for large commercial facilities across Colorado.

With over 30 years of experience installing and repairing EPDM roofing systems, L.E. Roofing brings engineering-grade precision to every project.


Whether your building needs a full EPDM replacement, a restoration, or expert leak investigation, we deliver workmanship built to stand the test of time.

Your roof is a system. We treat it like one.

Why Choose EPDM for Your Commercial Roofing System?

EPDM is engineered for strength and longevity — especially in extreme environments like Colorado.

Outstanding Weather Resistance

EPDM performs exceptionally well in:

- Freeze–thaw cycles

- High UV exposure

- Wind uplift

- Colorado’s dry climate

- Sudden temperature swings

Its elasticity allows it to expand and contract without cracking or breaking.

Decades of Proven Performance

EPDM roofs are known to last 25–40+ years when properly installed and maintained.

Excellent UV & Ozone Resistance

Unlike some membranes, EPDM resists degradation from sunlight — critical in Colorado’s high-elevation UV exposure.

Ideal for Large Commercial Roofs

EPDM is commonly used on:

- Schools

- Warehouses

- Distribution centers

- Manufacturing plants

- Office buildings

- Government facilities

- Multi-family housing complexes

Cost-Effective Installation & Long-Term Value

EPDM offers one of the best lifecycle costs of any commercial roofing material.

When installed with precision, EPDM is a top-tier choice for long-term protection.

Our EPDM Roofing Installation Process

Commercial roofing requires detail, discipline, and an engineering mindset.
Here’s how L.E. Roofing builds EPDM systems that last decades:

1. Detailed Roof Assessment

We examine:

  • Deck condition

  • Insulation needs

  • Existing membrane issues

  • Drainage patterns

  • Penetrations and flashing risks

Every EPDM system begins with a technical evaluation.

2. Insulation & Coverboard Setup

Most high-performance EPDM systems include:

  • Polyiso insulation

  • High-density coverboards

  • Vapor barriers (when required)

These layers strengthen the roof and improve thermal performance.

3. EPDM Membrane Installation

We install:

  • 45mil, 60mil, or 90mil membranes

  • Fully adhered, mechanically attached, or ballasted assemblies

  • Large seamless sheets to reduce potential leak points

4. Precision Flashing & Detailing

Penetrations are the most common leak points — we treat them with unmatched precision:

  • HVAC curbs

  • Drains and scuppers

  • Parapet walls

  • Skylights

  • Vent pipes

Our crews follow strict detailing protocols to ensure watertight performance.

5. Final Inspection & Quality Control

Every EPDM system is carefully reviewed:

  • Seam testing (for adhered seams)

  • Fastener pattern verification

  • Drainage performance

  • Perimeter anchoring

  • Flashing integrity

Your roof receives the same quality standards we use on federal installations.
