The Smart Alternative to Tear-Off: Single-Ply Retrofit for Commercial Metal Roofs
February 5, 2026

The Metal Dilemma: Why a Carlisle TPO Retrofit is the Superior Choice for Your Facility

If your commercial building in the Piedmont Triad is topped with an aging, leaky metal roof, you face a critical decision. Corrosion, loose fasteners, and failing seams lead to water intrusion, increasing your maintenance burden and risking damage to your building’s operations.

At B&D Roofing Solutions, we’ve spent over a decade helping business owners navigate this exact problem. Since establishing our roots in High Point in 2012, and now operating from our base in Thomasville, we’ve found that the most effective solution isn’t a costly tear-off—it’s a precision-engineered Single-Ply Retrofit System.

The Engineered Alternative to a Tear-Off

As a Licensed NC Building General Contractor and a Carlisle Authorized Applicator, we don't believe in "patching" a systemic problem. A metal roof retrofit involves installing a high-performance Carlisle TPO (Thermoplastic Polyolefin) membrane system directly over your existing panels.


This process is ideally suited for exposed-fastener systems, including:

  • R-Panels (PBR Panels): The standard for pre-engineered metal buildings.
  • Corrugated Panels: The classic, wavy profile found on older industrial structures.
  • Agricultural Panels: Through-fastened panels where the fasteners penetrate the entire structure.

The B&D Retrofit Process: A Seamless Shield

A retrofit requires more than just a membrane; it requires a structural understanding of how your building breathes. We bridge the gaps of your metal roof to create a flat, stable, and thermally efficient substrate.

  1. Structural Assessment: We begin by securing loose fasteners and treating rust to ensure your building's frame is ready for the upgrade.
  2. Creating a Level Plane: We install specialized Thermal Spacer Blocks or high-density Polyiso insulation (flutes) directly into the valleys of your metal panels. This eliminates the "ribbed" profile, creating a level surface and significantly increasing your roof’s R-value.
  3. Carlisle TPO Membrane: We install a durable, white Carlisle SynTec membrane over the new substrate. Every seam is heat-welded to create a single, monolithic, and watertight surface.

Why a TPO Retrofit Wins Over a Total Replacement

  1. Drastic Cost Savings & Zero Disruption A full tear-off is the most expensive route, involving demolition labor and disposal fees. A single-ply retrofit eliminates these costs and—most importantly—allows your business to remain fully operational during installation. No falling debris, and no exposure to the weather.
  2. Permanent Waterproofing New metal roofs rely on thousands of panel seams and exposed fasteners—all potential fail points. By installing a Carlisle TPO system, you replace those thousands of vulnerabilities with one continuous, seamless membrane that is permanently sealed against the elements.
  3. The Energy Edge Metal roofs are notorious for "heat gain." By adding a mandatory layer of high-R-value insulation during the retrofit, we help you slash your long-term cooling expenses. In the North Carolina heat, the energy savings alone often pay for the system over time.
