Roof Retrofit Systems

Stronger Performance Without Full Replacement

WHO ARE RETROFITS FOR?

Designed for Buildings That Need an Upgrade

Retrofit systems are ideal for:

  • Aging metal roofs

  • Buildings facing updated wind or energy codes

  • Properties with recurring leak issues

  • Owners seeking long-term improvement without full removal

  • Facilities that cannot afford major operational downtime

If your structure is sound but the roof system is underperforming, retrofit may be the right solution.

WHAT A RETROFIT SYSTEM IS

A New Roof Installed Over the Existing One

A retrofit system installs a new engineered roofing assembly over the current roof structure without removing the original system.

This approach strengthens performance, improves insulation or drainage when needed, and brings the roof into compliance with current codes, all while reducing tear-off costs and landfill waste.

RETROFIT VS. FULL REPLACEMENT

Understanding the Difference

Full Replacement involves removing the entire existing system down to the deck before installing a new roof. Retrofit reinforces or overlays the existing structure when conditions allow, preserving portions of the assembly while upgrading performance. Retrofits typically reduce disruption, lower labor costs, and accelerate installation timelines. However, they require proper structural evaluation to confirm suitability. A professional assessment determines which path protects long-term value.

RETROFIT INSTALLATION PROCESS

A Structured Restoration Approach

Execution quality and engineering alignment determine long-term performance.

01

Structural and system evaluation

02

Engineering design (if required)

03

Surface preparation and repairs

04

Framing or sub-purlin installation (as needed)

05

New roofing system installation

06

Final inspection and documentation

COMMON RETROFIT USE CASES

Where Retrofits Perform Best

This service is ideal for industrial facilities, warehouses, and manufacturing buildings that require durable, high-performance protection. It also supports retail centers with metal roofing, institutional buildings, and large-span structures where structural integrity and long-term reliability are essential.

Retrofits are especially effective on metal roofing systems nearing the end of service life but still structurally stable.

WARRANTIES & LONGEVITY

Long-Term Performance with Manufacturer Support

When properly designed and installed, retrofit systems qualify for manufacturer-backed warranties. System lifespan varies by material and design, but retrofits often deliver decades of additional service life when paired with routine maintenance.

Frequently Asked Questions

In many cases, yes, particularly when tear-off costs and downtime are significant factors.

Engineering review confirms load capacity before installation.

No. Structural integrity and existing system condition must be evaluated first.

Properly engineered retrofit systems can address wind, energy, and compliance requirements.
