Project Overview: Copper Manufacturer — EPDM + PVC Re-Roof (Cedar Rapids, IA)
This project delivered a large-scale reroof for an industrial copper manufacturer in Cedar Rapids, Iowa, covering a total
surface area of 455,400 sq. ft. The scope included 3,970 squares of Firestone EPDM reroof
and an additional 584 squares of PVC. The objective was clear: restore watertight performance, improve
long-term reliability at critical details, and execute the work with controlled logistics to support ongoing operations.
Assessment & Work Planning for an Active Industrial Site
Industrial reroofs are won at the planning stage. We evaluated existing field conditions to identify risk areas that drive
leaks and maintenance—drainage transitions, curb and penetration details, perimeter edges, and wall tie-ins—then built a
plan that prioritizes safe access, clean staging, and predictable daily progress.
Because EPDM and PVC systems have different detailing requirements, the process focused on scope clarity and consistent
standards—so every area was installed with the correct assemblies, transitions, and terminations for long-term performance.
- Review existing roof zones and identify active leak risks and drainage constraints.
- Confirm scope boundaries between EPDM reroof areas and PVC areas for clean transitions.
- Plan staging, laydown, and material movement to reduce disruption to operations.
- Standardize detail execution (penetrations, edges, walls) to reduce future maintenance.
Why Details Matter Most on Large EPDM + PVC Reroofs
On large-footprint facilities, the membrane is only part of the system. Performance depends on the details: terminations,
penetrations, transitions, and drainage. A disciplined, detail-first approach reduces callbacks, improves reliability in
severe weather, and helps ownership teams plan maintenance more predictably.
- Watertight transitions at penetrations, curbs, and equipment areas where leaks typically start.
- Consistent edge and wall details to help resist wind events and movement over time.
- Clear sequencing to keep work areas controlled and minimize operational impact.
- Cleaner closeouts that reduce debris, improve safety, and support long-term roof performance.
Results & Takeaways
The finished reroof restores watertight integrity across a major facility footprint with systems selected to match each
roof area’s needs—Firestone EPDM for the primary reroof scope and PVC where required. By emphasizing transitions, drainage,
and termination consistency, the project is positioned for stronger long-term reliability and fewer recurring problem areas.
The takeaway for industrial owners is simple: large roofs demand repeatable standards. When the same quality expectations are
applied across every detail, the roof performs more predictably and maintenance becomes easier to manage year after year.
