What Are Corrugated Metal Roof Skylights?
Corrugated metal roof skylights are specialized daylighting windows designed to fit the ridged, wavy pattern of metal roofing panels. These skylights come in different shapes and profiles to align seamlessly with popular corrugated roof types like R-panel, 5V crimp, and classic wavy panels found in barns, homes, and industrial buildings.
The most common options for skylights in corrugated metal roofs include fixed polycarbonate panels, domed acrylic skylights, tubular skylights, and framed glass skylights. Each style aims to offer weatherproof integration with the unique profile of corrugated roofing sheets.
Primary Benefits Of Skylights In Corrugated Metal Roofs
Natural Light Enhancement
The main advantage of corrugated metal roof skylights is improved access to daylight. Even north-facing or deep buildings benefit from natural light, reducing the reliance on artificial lighting during the day and enhancing interior environments.
Energy Efficiency & Savings
Well-installed skylights lower electric lighting costs. Some versions also help with passive solar heating, reducing winter energy bills. Vented skylights can improve airflow, lessening a building’s cooling needs in the summer.
Ventilation & Air Quality
Operable skylights introduce fresh air and reduce humidity. This is particularly useful in kitchens, bathrooms, workshops, or any space that needs extra ventilation, helping maintain comfort and indoor air quality.

Attractive, well-integrated skylights elevate both the appearance and market worth of a property. Whether for a modern home or a remodeled warehouse, skylights make spaces feel larger, brighter, and more inviting.
Popular Types Of Skylights For Corrugated Metal Roofs
Fixed Skylights
Fixed skylights offer permanent daylight with no ventilation function. They’re generally less expensive and have fewer moving parts, which enhances their weather resistance. Commonly constructed using tempered glass or UV-resistant polycarbonate.
Vented Skylights
Vented skylights (manual or electric opening) provide both daylight and airflow. These are ideal for attics, kitchens, sheds, and other rooms needing improved ventilation. Advanced options include remote-controlled mechanisms and rain sensors.
Tubular Skylights (Sun Tunnels)
Tubular skylights, also known as sun tunnels or solar tubes, use a reflective shaft to channel light from roof to interior rooms. They’re perfect for small spaces like hallways, closets, and bathrooms, requiring a minimal roof opening and offering outstanding energy efficiency.
Domed Acrylic Or Polycarbonate Skylights
Domed skylights are lightweight, impact-resistant, and well-suited to corrugated roof contours. Their curved surface sheds water and resists debris buildup. Typically framed in aluminum or PVC, they offer good value and are widely used in commercial settings.
Material Choices For Corrugated Metal Roof Skylights
Glazing Material Overview
- Polycarbonate: Extremely tough, lightweight, and UV-resistant, polycarbonate skylights are ideal for harsh climates and areas prone to hail or impact.
- Acrylic: Cost-effective, light, and available in clear or tinted forms. Slightly less impact resistant than polycarbonate but offers good optical clarity.
- Glass: Used in framed skylights where aesthetics and insulation are priorities. Laminated and tempered glass types resist breakage and provide top-tier clarity.
Frame & Flashing Options
- Aluminum Frames: Durable, corrosion-resistant, and light; commonly paired with factory-attached flashing for water-tightness.
- PVC/Plastic Composites: Low-cost and weatherproof, suitable for DIY installations and areas with moderate environmental exposure.
- Steel or Custom Metal Frames: Used in bespoke or commercial contexts to match existing roofing materials.

Skylight Sizing For Corrugated Metal Roofs
The optimal skylight size depends on the space’s dimensions, desired daylight, and roof structure. General guidance suggests that the skylight should be no larger than 5% of a room’s floor area when supplemental daylight is needed, or 10%-15% for spaces relying mainly on natural light.
- For bedrooms and living areas: Rectangular skylights (2’x4’, 4’x4’, 2’x6’, etc.)
- For hallways, closets, or bathrooms: Tubular skylights (typically 10”-14” in diameter)
- For large open areas: Multiple units or custom skylight runs
Installation Considerations For Corrugated Metal Roof Skylights
Structural & Framing Issues
The corrugated pattern of the roof requires precise cutting and proper framing for each skylight opening. Framing should transfer the skylight load to roof rafters while maintaining the roof’s strength and wind resistance.
Waterproof Flashing & Sealing
A watertight install is critical with corrugated metal roofs due to the risk of leaks along ridges and valleys. Custom or kit flashing solutions are recommended, combined with high-quality roofing sealants and compatible fasteners.
Professional installers often use pre-fabricated curb kits designed for metal roofs to elevate the skylight above the roof line and ensure water flows harmlessly around the opening.
Cutting The Roof Panel
Cutting corrugated metal may require metal snips, jigsaws, or rotary tools. Care should be taken to avoid damage to adjacent roofing and to seal exposed cut edges against rust.
Thermal Expansion & Weather Resistance
Proper installation accommodates metal roof expansion/contraction and prevents warping or loosening of skylight fasteners. Flexible, UV-stable seals and gaskets should be used for long-lasting performance.
Common Skylight Installation Methods
Direct Mount (Panel Replacement)
Some polycarbonate or acrylic skylights are shaped to directly replace a portion of the corrugated panel. This approach is fast and often used in barns, warehouses, and utility buildings, but may offer less insulation and durability than framed units.
Curb-Mount Installation
Curb-mount skylights are set atop a raised “curb” built onto the roof deck. This is the preferred method for most homes, as it elevates the skylight and allows for proper drainage, insulation, and flashing.
Retrofit Kits
Many manufacturers offer retrofit kits with flashing specifically molded for different corrugated profiles. These kits simplify integration and minimize the risk of leaks compared to site-built assemblies.
Potential Problems And How To Avoid Them
Leak Prevention
Leaks remain the primary concern with metal roof skylights. Avoid “shortcut” installation methods, use all recommended gaskets, and never skimp on flashing. Regularly inspect and reseal as needed, especially after severe weather.
Condensation Control
Poorly insulated skylights can lead to interior condensation in climates with high humidity or temperature swings. Opt for insulated glass or double-layer polycarbonate where condensation is a concern, and ensure the skylight is properly ventilated.
UV And Hail Resistance
Choose glazing materials with high UV resistance (especially in southern and western U.S. regions) to avoid yellowing and brittleness. In hail-prone areas, select impact-rated products and confirm roof insurance coverage for skylight additions.
Energy Efficiency Features In Modern Skylights
- Low-E Glass Coatings: Reduce solar heat gain while maximizing visible light, ideal for southern sun exposures.
- Argon/Krypton Gas Filled Units: Improve insulation value in glass skylights.
- UV-Blocking Layers: Protect interiors from fading and extend roof/skylight lifespan.
- Operable Shades/Blinds: Allow for user-control over daylighting and heat influx.
- Thermal Break Frames: Prevent heat loss through the skylight perimeter.
Cost Breakdown: What To Expect
The total cost for adding a skylight to a corrugated metal roof depends on product type, roof height, complexity, labor, and required structural changes. Below is an estimated cost breakdown for typical installations:
| Skylight Type | Materials Only | Total Installed (Avg.) |
|---|---|---|
| Fixed Polycarbonate Panel | $60 – $250 | $250 – $600 |
| Rectangular Glass Skylight (curb-mount) | $300 – $800 | $800 – $2,000 |
| Domed Acrylic Skylight | $180 – $550 | $600 – $1,250 |
| Tubular Skylight (Sun Tunnel) | $250 – $600 | $600 – $1,200 |
Professional installation is strongly recommended for all but the simplest panel replacements. Labor may increase in cases of steep roof slopes, multi-story buildings, or extensive flashing work. DIY installs can cut costs but risk leaks if not done precisely.
Building Codes, Permits, & Warranties
Most municipalities require a building permit for skylight installation due to structural and weatherproofing concerns. Selected skylight models should meet local energy codes (such as Energy Star requirements) and be installed according to manufacturer specs to maintain warranties.
In high-wind, hurricane, or snow belt zones, special hurricane-rated or impact-resistant skylights may be mandated. Always confirm with local building authorities before purchase or installation.
Maintenance And Longevity
With proper installation, quality skylights in corrugated metal roofs can last 20+ years. Maintenance tasks include:
- Regularly cleaning glazing surfaces with non-abrasive cleaners
- Inspecting and resealing flashing every 1-2 years
- Checking for debris that could trap water or damage the frame
- Promptly repairing or replacing cracked, leaking, or yellowed units
Professional roof inspections can identify skylight-related problems early. Proactive care ensures optimal energy efficiency, daylight, and moisture protection throughout the skylight’s lifespan.
