When it comes to building upgrades, full tear-offs aren’t always necessary or practical. That’s where metal panel retrofits come in. Whether you’re dealing with a leaking metal roof, aging siding, or a flat roof that needs slope, retrofitting lets you install new panels over an existing structure without ripping it down to the bones.
Retrofits offer a smarter, faster, and more cost-effective way to restore performance, improve aesthetics, and extend building life without the hassle of a full replacement.
What Exactly Is a Metal Panel Retrofit?
A metal panel retrofit is the process of installing a new layer of steel panels either roofing or siding over an existing structure. Instead of tearing off the old system, retrofit framing (like hat channels or sub-purlins) is added to create a new surface for the updated panel install.
Depending on your goals, this might mean:
- Adding slope to a flat roof
- Strengthening thermal protection with added insulation
- Sealing up weather-worn areas
- Updating a dated or damaged exterior
Retrofits can be done with both concealed fastener systems (like Snap Lock or Mechanical Lock) and exposed fastener panels (like PBR or U Panel), depending on your needs.
Benefits of a Metal Panel Retrofit
| Benefit | Why It Matters |
| Faster Turnaround | No demo = less downtime. Your crew can get in, get it done, and move on quickly. |
| Lower Cost | Save on labor, waste removal, and structural repairs—especially with intact substrate. |
| Better Weather Protection | Boost performance against wind uplift, water intrusion, and storm exposure. |
| Minimal Disruption | Ideal for active buildings (warehouses, industrial, commercial) that can’t shut down. |
| Code Compliance | Retrofit panels can still meet UL 580, UL 2218, and TDI standards when installed properly. |
Common Use Cases for Metal Panel Retrofits
Retrofits are especially useful in industries or building types where function matters more than fancy finishes though you can still get a great aesthetic upgrade too.
Some of the most common retrofit projects include:
- Rusted-out metal roofs on old barns or warehouses
- Flat-to-slope conversions on industrial or retail buildings
- Damaged or outdated siding on commercial offices or storage units
- Weatherproofing upgrades on buildings in wind/hail zones
- Thermal improvements through insulation add-ons or vented systems
Tips for Planning a Retrofit That Lasts
If you’re taking on a retrofit, success comes down to the details. Here’s how to set yourself up for a solid install:
- Choose the right panel profile. PBR and Snap Lock are great retrofit choices depending on slope and exposure.
- Confirm your substrate. You’ll need to know what you’re attaching to whether it’s metal deck, old panels, or purlins.
- Use compatible fasteners and closures. Retrofit framing may require longer fasteners or specialty clips.
- Consider a new underlayment or vapor barrier. Just because you’re not tearing off doesn’t mean you can’t improve what’s underneath.
- Ask about warranty coverage. Some panel systems still qualify for paint or weather warranties even in retrofit use if properly installed.
