Winston-Salem’s commercial buildings have a lighting problem that most business owners never think about. Walk through a warehouse or manufacturing facility in the Triad and chances are you’ll see natural light coming through aged, yellowed skylights that barely let in enough brightness to justify their existence. We just finished a commercial roofing in Winston-Salem project in Greensboro where replacing old skylights transformed the workspace from dim to daylight. If your building relies on skylights for natural light, there’s a good chance they’re costing you more in energy bills than you realize while delivering a fraction of the illumination they’re designed to provide.
What We Found on This Greensboro Commercial Roof
The building had been using skylights for decades. The panels had done their job for years, but time and UV exposure had turned them from clear light transmitters into foggy yellow filters. You could look up at them from inside the building and see they were there, but the amount of actual usable light coming through was minimal.
Standing inside before the replacement, the workspace felt dim even on a bright afternoon. Employees were working under artificial lights that stayed on all day because the skylights just weren’t pulling their weight anymore. The plastic had degraded, the clarity was gone, and the building owner was paying for both the electric lights and the heat loss through those old panels.
We pulled the old skylights and installed new units. The difference was immediate and dramatic. It looked like somebody had flipped a switch. The same building, same roof openings, but now you had actual daylight flooding the space.
Why Commercial Roofing Winston-Salem NC Building Owners Should Care About Skylight Performance
Skylights degrade slowly, so you don’t notice the change happening. Year after year, the plastic yellows a little more, the UV protection breaks down, and the light transmission drops. You adapt by turning on more overhead lights earlier in the day. Your energy bills creep up. Your workspace gets dimmer without you really registering why.
Old skylights create three problems at once. First, they fail at their primary job of providing natural light. Second, they lose thermal efficiency as the materials break down, which means you’re losing conditioned air through the roof. Third, the seals around aged skylights often start leaking, which leads to water damage that can spread to insulation, decking, and interior finishes.
We’ve seen buildings in Davidson County and throughout the Triad where the owner installed high-efficiency HVAC systems and LED lighting to cut costs, but left thirty-year-old skylights in place. Those old panels undermine every other efficiency upgrade you make.
North Carolina summers mean your roof is absorbing serious heat. A skylight should bring in light without turning your building into a greenhouse. Modern skylight technology includes better UV protection, improved insulation values, and coatings that manage heat gain while maximizing visible light transmission. An old skylight gives you the worst of both worlds: poor light and poor thermal performance.
The Skylight Replacement Process We Used
We started by assessing the existing skylight curbs and flashings. In this case, the structural curbs were in good shape, which meant we could replace just the skylight units themselves without tearing into the roof system. That saved time and kept the project cost-effective compared to a full curb replacement.
We removed the old skylight panels carefully to avoid damaging the surrounding roof membrane. Each opening got inspected for any water damage or deterioration around the curb. The flashings were still performing well, but we checked every seal point because a new skylight on a compromised curb is a leak waiting to happen.
The new skylights went in with fresh gaskets and proper sealing at every connection point. We pay close attention to the interface between the skylight frame and the roof membrane because that’s where most skylight leaks originate. The units we installed have UV-resistant glazing that’ll maintain clarity and light transmission for decades, not years.
The whole project moved quickly once we had the new units on site. Weather cooperated, which matters when you’re opening up a roof. We covered the openings during the transition to keep the building dry, installed the new skylights, sealed everything properly, and cleaned up.
The building owner saw the difference immediately. Natural light reached corners of the facility that had been dark for years. Workers noticed it right away. One of them told us it felt like they’d been working in a cave and someone finally opened the curtains.
Signs Your Commercial Building Needs Skylight Replacement
Here’s what to look for if you’re wondering whether your skylights are past their prime:
- Yellowed or clouded plastic — if the panels look discolored or hazy from below, they’re blocking a significant percentage of available light
- Interior lights stay on all day — skylights should reduce your reliance on artificial lighting during daylight hours, not require supplemental lighting underneath them
- Hot spots under skylights in summer — old glazing loses its ability to manage solar heat gain, turning your skylights into solar ovens
- Water stains around skylight curbs — any discoloration on the ceiling near skylights indicates seal failure or flashing problems
- Crazing or cracks in the glazing — visible damage to the plastic means structural integrity is compromised and leaks are likely
- Age over 20 years — if your skylights were installed in the 1990s or earlier, the materials have degraded significantly regardless of how they look
- Condensation between layers — double-glazed skylights that show moisture inside the unit have failed seals
- Your roof is being replaced — skylight replacement should happen at the same time as roof replacement to ensure proper integration
Business owners often focus on obvious roof problems like leaks or damaged membranes while ignoring skylights that are quietly underperforming. Your Commercial Roofing services inspection should include a skylight assessment, especially if your building depends on natural light for warehouse, manufacturing, or retail operations.
We recommend annual roof inspections that include checking skylight condition. Catching degradation early means you can plan a replacement project instead of responding to an emergency leak during a thunderstorm.
Why Sunny Sky Roofing LLC for Commercial Roofing Winston-Salem NC Projects
We’ve replaced skylights on commercial buildings throughout the Triad, from small warehouse facilities to large manufacturing plants. The work requires understanding both roofing systems and skylight integration. Get it wrong and you create leak points that damage the building. Get it right and you improve both the workspace and the building’s energy performance.
We work with quality skylight manufacturers and follow proper installation protocols at every step. The connection between skylight and roof is critical. We don’t rush that work or cut corners on sealing and flashing details.
Our approach focuses on long-term performance. A skylight should last decades without leaking, maintain light transmission, and contribute to your building’s efficiency rather than undermining it. We select products and installation methods that deliver that kind of durability.
We’re based in Lexington and we serve commercial properties throughout Davidson County and the Winston-Salem area. We know the weather patterns here, the building types common in this region, and the roof systems that work long-term in North Carolina’s climate. That local knowledge matters when you’re trusting someone to open up your roof and install components that need to perform in summer heat, winter cold, and everything in between.
According to the National Roofing Contractors Association, proper skylight installation requires attention to flashing details, curb construction, and integration with the roof’s water management system. We follow those industry standards because they’re based on decades of real-world performance data.
Frequently Asked Questions About Commercial Skylight Replacement
How long do commercial skylights typically last?
Most commercial skylights have a functional lifespan of 20 to 30 years depending on the glazing material and exposure conditions. Polycarbonate and acrylic glazing degrades faster under UV exposure than glass, but even glass units experience seal failure and frame deterioration over time. If your skylights are approaching 20 years old, it’s time to evaluate their performance and plan for replacement before they start leaking or fail completely.
Can you replace skylights without replacing the entire roof?
Yes, in many cases we can replace just the skylight units while leaving the existing curbs and roof system in place. This works when the curbs are structurally sound and the surrounding roof membrane is in good condition. We inspect the curbs and flashings carefully before recommending this approach. If the roof itself is near the end of its service life, it makes more sense to coordinate skylight replacement with a full roof replacement so everything integrates properly.
Will new skylights really make that much difference in lighting?
The improvement is dramatic when you replace heavily aged skylights. New glazing can transmit 80% or more of available light compared to 30-40% transmission through yellowed, degraded panels. That difference is immediately visible to anyone working in the building. Better natural light means you can reduce artificial lighting during daylight hours, which cuts energy costs. Employees also respond positively to improved natural light, which can affect productivity and workplace satisfaction.
Should I upgrade to impact-resistant skylights?
Impact-resistant glazing makes sense for buildings in areas with frequent hail or where falling debris from nearby trees is a concern. North Carolina gets severe thunderstorms that can produce damaging hail. The upgrade cost is modest compared to the expense of emergency repairs after a hail storm punches through standard glazing. We evaluate your building’s exposure and recommend impact-resistant options when the risk justifies the additional investment.
