Skylights for Metal Roofs
A skylight can transform a dark room into the brightest one in the house — and yes, you can absolutely have one on a metal roof, as long as it’s done the right way.
Skylights are one of the most popular ways to bring natural light deep into a home, but homeowners often assume a metal roof rules them out. It doesn’t. The key is the mounting method: a curb-mounted skylight is designed to integrate with a metal roofing system, and it’s compatible with every Interlock profile. Because a skylight is a penetration through the roof, though, it’s exactly the kind of detail that depends on proper installation.
Here’s how skylights work with an Interlock metal roof and the real benefits they bring — from energy and comfort to mood and home value.
Curb-mounted skylights are compatible with all Interlock Lifetime Metal Roofing Systems — natural light without compromising watertightness.
Can you install skylights on a metal roof?
Curb-mounted skylights are compatible with all Interlock Lifetime Metal Roofing Systems. A curb — a raised, watertight frame — is built into the roof, and the metal panels and flashing are fitted around it so the skylight integrates seamlessly without compromising the roof’s watertightness. Beyond the light itself, skylights can help heat a room in winter, vent hot air in summer, improve mood, and add value — provided they’re professionally installed.
How Skylights Work with Interlock Metal Roofing
The secret to a leak-free skylight on a metal roof is the curb. A curb is a raised, watertight frame built up from the roof deck, onto which the skylight is mounted. The metal panels and their flashings are then fitted up and around the curb so that water is directed away from the opening on all sides, exactly as it is at any other roof transition. Curb-mounted skylights are compatible with all Interlock Lifetime Metal Roofing Systems, so adding daylight doesn’t mean compromising the integrity of the roof — the skylight becomes just another well-flashed detail in the system.
5 Benefits of Skylights on a Metal Roof
Skylights do far more than look good. First, natural light: they flood interior spaces with daylight that windows alone can’t reach. Second, warmth: a south-facing skylight can passively help heat a room in winter. Third, ventilation: an operable skylight vents hot air that rises to the ceiling, cooling a room in summer. Fourth, well-being: more natural light improves mood and can help reduce seasonal affective disorder (SAD). And fifth, value: tasteful, well-placed skylights are an attractive feature that can add appeal and value to a home.
Choosing the Right Direction and Placement
Where a skylight faces changes what it does. A south-facing skylight captures the most sun, helping warm a room in winter — a benefit in cooler climates but something to manage with shades in hot ones. North-facing skylights give soft, even light with less heat gain, ideal for studios and consistent daytime illumination. East and west placements catch morning or evening sun. Placement within the room matters too: a skylight over a kitchen, stairwell, or bathroom can brighten exactly the spaces that windows struggle to reach.
Skylights and Energy
Done thoughtfully, skylights can support an energy-efficient home: free daylight reduces the need for electric lighting, passive solar gain can offset winter heating, and operable units aid summer ventilation. The flip side is that a poorly chosen or poorly placed skylight can add unwanted heat gain or loss, so modern energy-rated glazing and smart orientation matter. Paired with a reflective metal roof, the overall effect on comfort and efficiency can be very positive — see metal roof energy efficiency for the bigger picture.
Why Professional Installation Is Essential
A skylight is a hole cut in your roof, which means watertightness lives entirely in how it’s flashed and integrated. On a metal roof, the curb, the panel terminations, and the flashing all have to work together precisely — the same systems thinking behind every Interlock detail. This is firmly professional territory: a correctly installed curb-mounted skylight stays dry for the life of the roof, while a poorly installed one becomes a chronic leak. It’s one more reason skylights belong in a professionally installed roofing system.
Bring In the Light
A metal roof and a bright, daylit home aren’t at odds — with curb-mounted skylights compatible across all Interlock systems, you can have both. Done right, skylights add light, warmth, ventilation, well-being, and value, all while the roof stays as watertight as ever.

Frequently Asked Questions
Can you install skylights on an Interlock metal roof?
Yes. Curb-mounted skylights are compatible with all Interlock Lifetime Metal Roofing Systems. The skylight mounts on a watertight curb, and the metal panels and flashing integrate around it to keep the roof dry.
Which direction should a skylight face?
South-facing skylights capture the most sun and can help warm a room in winter; north-facing give soft, even light with less heat. The best choice depends on your climate and the room.
Do skylights save energy?
They can. Daylight reduces electric lighting, south-facing units add passive winter warmth, and operable skylights vent summer heat. Energy-rated glazing and good placement maximize the benefit.
Will a skylight leak on a metal roof?
Not when properly installed. A curb-mounted skylight integrated with the panels and flashing stays watertight for the life of the roof — which is why professional installation is essential.
Do skylights help with mood?
Yes. More natural light is linked to better mood and can help reduce seasonal affective disorder (SAD), making skylights a wellness upgrade as well as an aesthetic one.
Can skylights be added to any Interlock profile?
Curb-mounted skylights are compatible with all Interlock Lifetime Metal Roofing Systems, so they can be integrated regardless of which profile you choose.
