Yes—in many cases, we can install a new industrial metal roof over old panels. This process, called a retrofit system, is a cost-effective way to upgrade your roof without a full tear-off. At L&L Roofing & Construction, we help Gainesville businesses decide whether a roof-over is safe, code-compliant, and the best choice for their building.
How Roof-Overs Work
- Structural Inspection: We first confirm the existing panels and deck can support a new system.
- Sub-Framing System: A lightweight grid is installed over the old panels to create a stable base.
- New Metal Panels: Standing seam or R-panels are installed on top, giving you a new watertight roof.
- Added Insulation: Retrofit systems often include insulation upgrades for energy efficiency.
Benefits of Roofing Over Old Panels
- Lower cost than a full tear-off.
- Faster installation with less disruption to your business.
- Avoids disposal costs and landfill waste.
- Extends roof life with modern, energy-efficient materials.
FAQ: Can You Roof Over Old Metal Panels?
Q: Is it always possible to install over old panels?
A: Not always. If the old roof is severely rusted, structurally unsound, or waterlogged, a full replacement is required.
Q: Does roofing over affect warranties?
A: No—when installed to manufacturer specs, retrofit systems carry full warranties.
Q: Will roofing over trap moisture?
A: Not with proper ventilation and insulation. We design systems to stay dry and breathable.
Q: Is it as durable as a full replacement?
A: Yes. A properly installed retrofit can last 40–60 years, similar to a new system.
At L&L Roofing & Construction, we believe in honesty, integrity, and doing the right thing. That means we’ll only recommend a roof-over if it’s safe and code-compliant for your building—otherwise, we’ll guide you toward the right replacement solution.
