Roof Replacement
Complete commercial roof replacement — new system, new warranty, new performance. Installed by C-39 certified crews.
Replace It Once. Replace It Right.
A commercial roof replacement is one of the largest capital expenditures a building owner makes. Done correctly, a new roof system delivers 15–25 years of reliable protection with a manufacturer-backed warranty. Done poorly, it leaks within years and requires costly remediation. El-Lay's C-39 licensed team ensures your replacement investment is maximized — right system, right installation, right warranty.
- System selection recommendation based on building use, budget, and performance requirements
- Full tear-off and deck inspection included as standard — no hidden deck repairs after commitment
- Manufacturer material warranty plus 2-year workmanship warranty standard
- All permits and final building department inspections included

What a True Replacement Includes
A commercial roof replacement isn't just a new membrane layer. It includes removal and disposal of the existing system, deck inspection and repair, new code-compliant insulation, proper drainage engineering, new membrane with heat-welded seams, all flashing details, edge metal, and manufacturer warranty registration — everything required to deliver a new, warranted roof system.
