What EPDM Roofing Is (and Where It Fits Best)

EPDM is a single-ply synthetic rubber membrane commonly used on commercial flat and low-slope roofs. It’s often selected for its flexibility, seam performance when installed correctly, and long-term value on the right building.

Common EPDM Applications

  • Warehouses and distribution facilities
  • Office buildings
  • Retail and mixed-use properties
  • Manufacturing buildings
  • Low-slope additions and rooftop mechanical areas

Why Building Owners Choose EPDM

  • Good fit for flat/low-slope roofs: Designed for membrane-style commercial roof systems.
  • Flexible material: Handles movement and temperature swings common in the Midwest.
  • Attachment options: Systems may be fully adhered, mechanically attached, or ballasted depending on roof design and goals.

EPDM Roof Repair: What We Typically Fix

Most commercial EPDM leaks start at details, not in the field of the membrane. Repairs commonly focus on seams, flashing transitions, roof penetrations, drains, and edge metal.

  • Open or aging seams
  • Flashing issues at walls, curbs, and equipment
  • Punctures and membrane damage
  • Drainage problems that lead to standing water
  • Storm-related damage

EPDM Roof Installation & Replacement

If your roof is approaching the end of its service life or repairs are becoming frequent, replacement may be the better long-term option. For installation and replacement projects, we’ll review roof condition, insulation needs, drainage, and critical details like penetrations and transitions before finalizing the scope.

How the Process Works

  1. Inspection: We review membrane condition, seams, flashings, penetrations, and drainage.
  2. Scope and options: Repair vs. replacement with clear tradeoffs and priorities.
  3. Scheduling: Plan work to reduce disruption for tenants, staff, and deliveries.
  4. Documentation: Before/after photos and a summary of completed work.
