Greensboro’s mix of aging industrial buildings, mid-century office parks, and newer commercial developments means we see a lot of roofs that have been maintained well enough to avoid catastrophe but not well enough to actually perform the way they should. Case in point: we just wrapped up a commercial roofing project where the building owner thought they had good natural light. They didn’t realize their skylights had degraded so badly that they were losing most of the daylight that should’ve been coming through. If you’re managing a warehouse, manufacturing facility, or office building in Greensboro and you’ve got skylights that are more than a decade old, you’re probably running interior lights all day when you shouldn’t have to. That costs money, and it’s fixable. This is what we do with commercial roofing Greensboro NC projects every week.
What We Found on This Greensboro Commercial Roof
The building had skylights that were still technically intact. No active leaks. No visible cracks from the ground. But when you got up on the roof and actually looked at them, the story changed. The plastic had yellowed and hazed over from years of UV exposure. The seals around the curbs had hardened and pulled away in spots. Inside the building, the light coming through was dim and amber-tinted, like looking through an old soda bottle.
The owner mentioned they’d been running overhead lighting during the day for years. They assumed that’s just how the building was. When we explained what new skylights would do, they were skeptical. Then we replaced them.
The difference was immediate. It looked like somebody flipped a switch. The same roof openings now flooded the space with clean, bright daylight. The building felt completely different inside. That’s not an exaggeration for effect—you can see it in the before-and-after comparison. Old skylights filter light like a dirty window. New ones don’t.
Why Skylight Replacement Matters for Commercial Roofing Greensboro NC Buildings
Greensboro sits in the Piedmont Triad, and our weather beats the hell out of roofing materials. We get hot, humid summers with intense UV. We get freeze-thaw cycles in winter. We get sudden temperature swings in spring and fall. Skylights take all of that directly, with no shade and no protection.
Over time, the acrylic or polycarbonate domes yellow and lose clarity. The gaskets dry out. The flashing around the curbs can separate if it wasn’t installed right in the first place. You end up with a skylight that’s costing you in three ways: reduced light transmission means higher electric bills, degraded seals mean potential leak points, and poor energy performance means you’re heating and cooling the outdoors.
Most building owners don’t think about skylights until they leak. By then, you’ve probably got water damage in the insulation and deck. You’ve been running lights unnecessarily for years. You’ve been paying for conditioned air that’s escaping through gaps you didn’t know existed.
Replacing aged skylights before they fail isn’t just about light. It’s about energy efficiency, leak prevention, and keeping your insurance company happy. It’s a proactive move that pays back faster than most commercial roofing Greensboro NC improvements.
How We Replace Commercial Skylights Without Disrupting Your Operation
We don’t tear off skylights and leave a building open to weather. The process is methodical and quick.
First, we order the new units to match the existing curb dimensions. If the curbs are in good shape and properly flashed, we reuse them. If they’re compromised, we rebuild them. Most of the time, the curbs are fine—it’s the dome and seals that have given up.
We pull the old dome off the curb, inspect the flashing and underlying roof membrane, address any issues we find, then set the new dome with fresh gaskets and fasteners. We test the seal, check the interior for any signs of past moisture intrusion, and clean up. Each skylight takes a few hours, depending on size and access.
The work happens on the roof. Your team works inside like normal. We’ve done this on active warehouses, operating manufacturing plants, and occupied office buildings. If it’s not raining, we can replace skylights without shutting you down.
We use quality units that meet or exceed the National Roofing Contractors Association standards for wind uplift, impact resistance, and thermal performance. This is the Triad—we get wind events, hail, and temperature extremes. Your skylights need to handle all of it.
Signs Your Greensboro Commercial Building Needs Skylight Replacement
Here’s what to look for if you’ve got skylights on your roof:
- Yellowed or cloudy domes: If the plastic looks discolored or hazy, it’s blocking a significant percentage of the light that should be coming through. You’re paying for electricity to make up the difference.
- Interior lights running all day: If your team needs overhead lighting during daylight hours in areas under skylights, the skylights aren’t doing their job.
- Visible cracks or crazing: Fine cracks in the dome material mean UV degradation. It’ll leak eventually, and it’s already compromised structurally.
- Gaps around the curb: If you can see separation between the dome and the curb, water is getting in. It might not be dripping inside yet, but it’s saturating your insulation.
- Water stains on the interior ceiling near skylights: This one’s obvious, but by the time you see stains, you’ve had moisture in the roof assembly for a while.
- Higher energy bills without explanation: Degraded skylights lose their insulating value. You’re heating and cooling the outdoors through those openings.
- Age over 15 years: Even if they look okay, skylights from the early 2000s or older are past their useful life. The materials have degraded, even if it’s not obvious from the ground.
If you’re seeing two or more of these signs, it’s time to replace. Waiting until they leak means you’re paying more in energy costs and risking water damage to the building structure.
Why Greensboro Business Owners Choose Sunny Sky Roofing LLC for Commercial Roofing
We’re based in Lexington, which puts us 25 minutes from Greensboro. We know the commercial building stock here. We know the weather. We’ve worked on everything from old textile mill conversions to modern distribution centers off I-40.
When we show up for commercial roofing in Greensboro, we’re not selling you a roof. We’re solving a problem. Skylights that don’t transmit light are a problem. Roofs that leak are a problem. HVAC units sitting on failing curbs are a problem. We fix the actual issue, not just the symptom.
We don’t upsell. If your curbs are fine, we tell you. If you can get another few years out of a section of membrane with targeted repairs, we’ll say that instead of pushing a full replacement. That approach has kept us busy for years in the Triad without spending a dime on advertising. Our work brings in the next job.
We also offer maintenance programs. Annual inspections catch small problems before they become expensive emergencies. For commercial buildings in Greensboro with flat roofs, HVAC equipment, and skylights, an annual inspection is the minimum. If you’ve got heavy tree coverage or a lot of rooftop penetrations, bi-annual inspections make sense. Either way, we’ll tell you what needs attention and what can wait.
Frequently Asked Questions About Commercial Skylight Replacement in Greensboro
How much light do I actually lose with old skylights?
It depends on the level of yellowing and hazing, but it’s common to lose 40% to 60% of light transmission with skylights that are 15 to 20 years old. The degradation happens gradually, so you don’t notice it day to day. But when you replace them, the difference is dramatic. We’ve had building owners tell us it’s like turning on stadium lights. Your eyes adjust to reduced light over time, so you don’t realize how dim it’s gotten until you see the comparison.
Can you replace skylights in winter?
Yes, as long as it’s not actively raining or snowing. The work happens quickly enough that we’re not leaving the building exposed for long. We avoid working in high winds or icy conditions, but a cold, clear day in January is fine for skylight replacement. We’ll schedule around the weather forecast and keep you updated if we need to shift the timeline.
Will new skylights improve my energy efficiency?
Absolutely. Modern skylights have better insulating properties, tighter seals, and UV-resistant coatings that reduce heat gain in summer. You’ll see lower HVAC costs, especially if your old skylights had gaps or degraded gaskets. The improved light transmission also means you can reduce or eliminate daytime interior lighting in those areas, which cuts your electric bill. The payback period on skylight replacement is usually shorter than most building owners expect.
How long do new commercial skylights last?
With quality units and proper installation, you should get 20 to 25 years. That assumes normal wear and tear and routine maintenance. We recommend inspecting skylights annually as part of your overall roof maintenance. Catching small issues early—like a fastener that’s backed out or a gasket that’s starting to separate—keeps them performing well for the full lifespan. Neglect will shorten that timeline significantly.
