We recently had the privilege of installing a 3‑story EPDM roofing system for CPARC in downtown Carlisle, Pennsylvania. What made this project especially meaningful is that the previous roof was installed incorrectly, leading to ongoing failures. Multiple leaks, rotted deck boards, and water intrusion had plagued the structure.
Now, with this new certified EPDM system in place, the owners can rest easy knowing they have a robust, long-lasting roof protecting their property.
The Problem: Failed Roof, Rotting Deck, Ongoing Leaks
When our team first assessed the building, we found serious issues:
- The prior roof had been installed improperly, without proper flashings or seals.
- Water had penetrated the membrane, leading to wood rot and structural weakening.
- Multiple active leaks had damaged interior finishes and threatened long-term integrity.
- Because it was a 3‑story building, the scale of failure had cascading consequences (access, safety, repair complexity).
Clearly, a simple patch job wouldn’t suffice. The project needed a full removal, correction of damaged substrate, and a properly engineered EPDM system.
The Solution: Certified EPDM Roofing System
We designed and installed a certified EPDM roofing system tailored for this 3‑story setup. Key steps included:
- Full strip-out of the failed system, including all compromised materials.
- Replace and repair the rotted wood decking with approved substrate materials.
- Precision detailing at all penetrations, parapets, flashing terminations, and drains.
- Install the new EPDM membrane, fully adhered or mechanically fastened per the manufacturer’s specs.
- Quality control inspections during and after installation to ensure system integrity.
- Final cleanup and client walkthrough, with education on maintenance and warranty.
With every layer executed properly, the new system now forms a unified, watertight barrier built to last.
Why EPDM Was the Right Choice
EPDM (ethylene propylene diene monomer) is a widely trusted roofing membrane, especially for low-slope and flat roofs. Its advantages include:
- Durability and long service life
- Weather and UV resistance
- Flexibility, which helps accommodate thermal expansion and building movement
- Ease of repair and maintenance
- Proven performance when installed according to certified standards
Given the existing building and the extent of prior damage, EPDM offered the reliability and structural compatibility needed.
The Results: Peace of Mind for Years to Come
Now that the project is complete:
- CPARC has a watertight, professionally installed 3‑story roof.
- The structural substrate is sound, with no lingering rot or weak points.
- The system is backed by manufacturer certification and workmanship guarantees.
- The owners no longer have to worry about recurring leaks or interior damage.
We’re grateful to CPARC for trusting our team to take care of their property. It’s always rewarding to turn a problematic roof into a lasting asset.
