This metal roof restoration Winston-Salem NC project addressed severe corrosion and fastener deterioration on a commercial metal panel roof system. Sunny Sky Roofing LLC completed a full restoration using a multi-layer fluid-applied coating system that sealed exposed fasteners and restored the roof’s weather resistance. The building owner avoided a complete tear-off and gained a renewed manufacturer warranty.
Why Winston-Salem Metal Roofs Develop Fastener Corrosion and Panel Deterioration
Metal roofs in Winston-Salem face a tough combination of UV exposure, temperature swings, and seasonal moisture. The fasteners that secure metal panels to the roof deck are particularly vulnerable because they penetrate the waterproof surface.
Over time, these fasteners expand and contract with the metal panels. The neoprene washers that seal each fastener compress and harden. Once the seal fails, water infiltrates around the fastener shaft.
This creates rust at the fastener head and on the underside of the panel. The rust spreads outward from each fastener point. In severe cases, the fastener loses holding strength and panels begin to lift during wind events.
We see this pattern most often on roofs that are 15 to 25 years old. The original coating has worn thin from UV degradation. The exposed metal oxidizes rapidly once the protective layer is gone.
What This Metal Roof Restoration Project Involved
We started with a complete roof inspection to document every area of concern. The fastener corrosion was widespread but the panels themselves remained structurally sound. This made the building a strong candidate for restoration rather than commercial roof replacement.
Our crew power-washed the entire roof surface to remove dirt, oxidation, and loose rust. We used a low-pressure technique that cleans without forcing water under the panels. All gutters and drains were cleared during this phase.
Next, we treated every corroded fastener with a rust-inhibiting primer. This step is critical because it stops active corrosion and provides a stable base for the coating system. We also resealed any fasteners that had backed out or lost their washer integrity.
We applied a base coat of fluid-applied metal roof coatings across the entire roof surface. This layer penetrates into seams and around fasteners. It creates a monolithic membrane that eliminates hundreds of individual leak points.
After the base coat cured, we installed a reinforcing fabric at all seams, penetrations, and fastener rows. The fabric embeds into the wet coating and adds tensile strength. This prevents cracking at stress points where metal expands and contracts.
We followed with a finish coat that provides UV protection and reflects solar heat. The white finish reduces surface temperatures significantly compared to the weathered gray metal underneath. This extends the life of the coating system and improves building energy performance.
Results: What Changed After This Project
- Eliminated active leaks caused by failed fastener seals and corroded panel edges
- Restored a continuous waterproof membrane across the entire roof surface
- Secured a 15-year manufacturer warranty on the coating system
- Extended the service life of the existing metal panels by decades
- Improved solar reflectance, reducing heat transfer into the building
- Avoided the cost and disruption of a complete roof replacement
- Provided a renewable coating system that can be recoated again in the future
What Winston-Salem Building Owners Should Know About Metal Roof Restoration
Metal roof restoration works best when the substrate is fundamentally sound. Panels with extensive rust-through or structural damage may still require replacement. We assess every roof individually before recommending restoration.
The coating system we use offers 10-, 15-, or 20-year manufacturer warranty options depending on the specific product and number of layers applied. These warranties require proper surface preparation and application by an approved contractor. Sunny Sky Roofing LLC maintains certifications with multiple coating manufacturers.
Restored metal roofs still need periodic inspections and maintenance. We recommend annual inspections to check for ponding water, debris accumulation, and minor damage. Catching small issues early prevents major problems and protects your warranty coverage.
Not every metal roof is a good candidate for restoration. Roofs with significant structural deflection, inadequate slope, or hidden moisture damage may need more extensive repairs first. Sometimes a combination of targeted commercial roof repair and coating is the right approach.
The climate in Winston-Salem is well-suited to fluid-applied coatings because we don’t experience the extreme freeze-thaw cycles seen in northern states. The coating remains flexible through our temperature ranges and maintains its adhesion to the metal substrate.
Why Commercial Property Owners in Winston-Salem Choose Sunny Sky Roofing LLC
We’ve completed Metal Roof Restoration projects on manufacturing facilities, distribution centers, and office buildings throughout the Triad. Our diagnostic approach identifies the root cause of problems rather than just treating symptoms.
Before we recommend restoration, we verify that the roof deck is dry and structurally sound. We use moisture meters and thermal imaging to detect hidden issues. If restoration isn’t the right solution, we’ll tell you that upfront.
Our crew completes the entire project from preparation through final coating. We don’t subcontract the work to less experienced applicators. Every team member understands how metal roofs perform and what details matter most.
Sunny Sky Roofing LLC serves commercial properties across the areas we service in the Triad including Winston-Salem, Greensboro, and High Point. We carry full liability insurance and workers’ compensation coverage on every project.
If your metal roof shows signs of fastener corrosion, panel rust, or active leaks, contact us for an honest assessment. Call Sunny Sky Roofing LLC at (336) 523-2103 or visit our contact page to schedule an inspection.
Frequently Asked Questions About Metal Roof Restoration in Winston-Salem
How often should a commercial roof in Winston-Salem be inspected?
We recommend annual inspections for most commercial roofs in the Winston-Salem area. Metal roofs benefit from semi-annual inspections if they’re older than 15 years or have a history of fastener problems. These inspections catch minor issues before they cause interior damage or void warranty coverage.
What causes fastener corrosion on metal panel roofs?
Fastener corrosion starts when the neoprene washer under each screw head degrades from UV exposure and temperature cycling. Once the seal fails, moisture reaches the steel fastener shaft and begins the oxidation process. The rust spreads outward and eventually compromises the fastener’s holding strength.
Does Metal Roof Restoration preserve my roof warranty?
Metal roof restoration typically replaces your original roof warranty with a new manufacturer warranty on the coating system. The coating warranty covers the restored roof assembly and can offer 10-, 15-, or 20-year coverage depending on the system selected. Any remaining warranty on the original metal panels is superseded by the coating warranty.
How long can Metal Roof Restoration extend my roof’s life?
A properly applied coating system can extend a metal roof’s service life by 15 to 25 years or more depending on the substrate condition and coating selected. The system is renewable, meaning you can recoat the roof again when the first coating reaches the end of its service life. This approach can effectively double or triple the original roof’s lifespan compared to replacement.
