How we approach an EPDM roof

Instead of starting with which membrane we can sell, we start with the building, the roof condition, and the evidence.

  1. 01

    Inspect

    We walk the full roof, and the underside of the deck where it’s accessible.

  2. 02

    Document

    Photos, measurements and marked-up findings, explained in plain terms.

  3. 03

    Diagnose

    We take core cuts on every flat roof, or use moisture evaluation, when the condition below the membrane matters.

  4. 04

    Present options

    Repair, restoration, and replacement, with the trade-offs explained plainly.

  5. 05

    Specify

    Membrane, thickness, attachment, insulation, cover board, drainage, and details.

  6. 06

    Execute

    A dedicated project manager plans the work around tenants, operations, access and weather, and keeps you updated every day.

  7. 07

    Verify

    Cleanup with a magnetic nail sweep, required inspections, a final walkthrough and closeout documentation.

  8. 08

    Maintain

    Follow-up and maintenance planning to protect the roof over its life.

We replace confusion with clarity.

Peace of mind

You’re taken care of

A dedicated project manager

Every project has a dedicated project manager who is your point of contact and coordinates with your facility or property manager.

Daily updates

Your project manager keeps you updated every day of the work, and we keep daily photo logs of the roof.

Cleanup and a magnetic nail sweep

At completion we clean up and run a magnetic nail sweep around the building.

A final walkthrough

We walk the finished roof with you before we call it done.

Workmanship warranty in writing

Your workmanship warranty terms are written into your contract, and we register the manufacturer warranty.

02 Roof assembly

What an EPDM roof system is made of

EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane installed in large sheets and joined with seam tape and primer. The membrane is the part you see, but the roof performs as an assembly. Select a layer to lift it out and see what we check.

EPDM membrane

Why this layer matters: the membrane is the primary waterproofing layer. EPDM sheets are joined with seam tape and primer, so seam quality is one of the biggest factors in how long the roof lasts.

What Blue Peaks checks

  • Seam laps, tape condition, and primer adhesion
  • Cuts, punctures, and service-traffic damage
  • Shrinkage and tension at the perimeter
  • Surface weathering and past repairs

Common failure signs

  • Lifted or open seam edges
  • Membrane pulled tight at walls and curbs
  • Leaks after storms near lap joints

Blue Peaks approach: before recommending replacement, we determine whether the problem is isolated, whether moisture is trapped below the membrane, whether drainage needs correction, or whether the roof is failing as a complete system.

03 Diagnostics

What can go wrong with an EPDM roof?

Select a condition to see where it shows up on a typical commercial roof, what you may notice, and what we inspect before recommending EPDM roof repair or replacement.

ROOF PLAN · ILLUSTRATIVE SEAMS · DRAINS · CURB Open lap at seam Perimeter tension / bridging Punctures near service path Wet insulation spreads below membrane Standing water 48 hrs+ Curb, pipe & wall flashing Impacts may not show at the surface

Condition

Open seam

EPDM sheets are joined with seam tape and primer. When a lap loses adhesion, water can travel under the membrane at the seam.

What you may notice

  • Water entry near lap joints
  • Interior leaks after storms

What we inspect

  • Seam tape condition
  • Primer adhesion
  • Shrinkage stress on the lap
  • Nearby wet insulation

Typical next step: localized repair may be possible if the rest of the roof is sound.

04 Specification

The EPDM choices that change roof performance

An EPDM proposal should tell you more than the membrane brand. Thickness, membrane type, color, and attachment all affect durability, wind performance, hail exposure, energy use, and long-term cost.
