Customer Reviews
John is from the old school where his handshake is as good as any piece of paper. I truly appreciated his immediate elevation of my knowledge about the project and look forward to working with he and his company.
John is fantastic.
Wonderful business to work with. Provided multiple quotes quickly. I'm a first time customer who called them out of the blue and he treated me like an old friend.
My husband and I loved working with this company! Prompt and professional workmanship!

Metal Roof Retrofit in North Carolina
100% Code-Compliant PEMB Metal Roof Retrofit Systems
Avoid structural collapse from ponding water weight. Inco Steel Buildings installs engineered, patented, purlin-bearing layover systems directly over red iron steel frames—with no roof removal required. We proudly serve commercial and industrial properties statewide, from the mountains to the ocean.
Cost Breakdown by Roof Over System
- PBR Metal Overlay (Exposed Fastener): Runs about $9.00 to $14.00 per square foot installed for 24 or 26-gauge steel materials
- Standing Seam Overlay (Concealed Fastener): Runs about $14.00 to $20.00 per square foot installed, for 24 or 26-gauge steel materials
$10-$20 Per Square Foot Inco Metal Roof Retrofit System
Laying over a metal roof costs between $9.00 and $20.00 per square foot installed. The final price depends on the panel type you choose:
- Exposed PBR fastners: Screws show on the outside. This style costs less. The majority of metal building in the USA are exposed fasteners.
- Concealed Standing seam fasteners: Screws are hidden. This style costs more.
These are two different roof styles, not the same thing. Contact Inco Steel Buildings for your free Metal Roof Retrofit quotation.
The Core Value Proposition
- Zero Down Time — Installed directly over your existing metal roof with no panel removal needed.
- Structural Safety — Engineered for purlin-bearing only to transfer loads safely to red iron frames.
- Eliminates Water Weight — Patented Roof Over® design prevents the water ponding that causes roof collapse.
- Premium Options — Choose between PBR exposed fastener or premium standing seam concealed fastener profiles.
- Statewide Compliance — One of the only 100% building code-compliant systems available from the NC mountains to the coast.
- Lifetime Protection — Backed by an industry-leading 40-to-45-year warranty on most North Carolina project locations.
PBR Panels vs. Standing Seam: Technical Engineering Profile
PBR Structural Panels (Pur-Lin Bearing R-Panel)
- Engineering Advantages: The PBR panel profile is designed with a deep 1.25-inch major rib height to maximize structural spanning capability over your existing red iron purlins. The exposed fastener system creates a rigid structural diaphragm across the roof plane, adding excellent lateral stability to older PEMB frames.
- Cost Efficiency: This profile offers the lowest initial capital cost per square foot while maintaining 100% building code compliance when paired with our patented Roof Over® retrofit framing.
Standing Seam Structural Panels
- Engineering Advantages: This premium profile uses floating concealed clips tucked beneath the panel seams, completely shielding fasteners from wind, rain, and UV degradation. The panels are mechanically seamed together in the field, creating a single monolithic steel barrier.
- Thermal Dynamics: Because metal panels expand and contract significantly with North Carolina’s temperature swings, the internal floating clips allow the roof to slide smoothly over the patented retrofit sub-framing. This eliminates stress on structural fasteners and completely prevents slotting or elongated screw holes over time.
The Hidden Danger of Standard Retrofit Reroofing
Many commercial metal building owners choose standard retrofit systems to save money, unaware that traditional methods often create severe structural risks for Pre-Engineered Metal Buildings (PEMBs).
The Threat of Catastrophic Roof Collapse
Traditional retrofits with commercial roofing products installed over panels can cause sagging metal panels. This design fails to correct existing structural deflections, causing the new roof to mirror old sags and create deep valleys. During heavy rainfall, these valleys trap massive amounts of pooling water. The resulting ponding water weight can quickly exceed the structural capacity of red iron steel frames, leading to catastrophic roof collapse.
Why Standard Retrofits Fail PEMB Requirements
- Improper Load Distribution: Standard systems place heavy, unengineered loads onto weak, secondary framing members.
- Voided Warranties: Traditional layovers frequently violate original building warranties by altering structural load paths.
- Code Non-Compliance: Most commercial retrofits fail to meet strict North American Specification (AISI S100) structural codes.
- Business Interruption: Traditional total-removal reroofing exposes your inventory, machinery, and tenants to rain damage.
The Inco Engineered Solution: Metal Roof Retrofit
The patented Inco Roof Over® system completely eliminates these structural liabilities. All sagging panels are repaired before layover with our metal straitening componets. Our system installs directly over your existing red iron steel frame using a purlin-bearing-only design. This transfers all weight safely to the main structural members, prevents water ponding, and requires zero roof removal.
Engineered Premium Panel Options
Standard reroofing forces you to halt operations, exposing your inventory, machinery, and tenants to the elements. The Inco Roof Over® system eliminates this risk entirely. By applying our engineered layover panels directly onto your existing red iron steel frame, we keep your business dry, safe, and fully operational throughout the entire installation process. Choose the application that fits your project needs:
- PBR Panels (Exposed Fastener Application): A highly cost-effective, heavy-duty solution that delivers exceptional structural strength and traditional industrial styling.
- Standing Seam Panels (Concealed Fastener Application): The premium choice for ultimate leak protection, hidden fasteners, and maximum thermal movement flexibility.
Both systems feature an advanced protective coating warranted for 40 to 45 years at most North Carolina project locations.
