Skylight Integration with Industrial Metal Roofing

Adding skylights to an industrial metal roof isn’t just about bringing in more light—it’s about getting it done right. At L&L Roofing & Construction, we’ve helped homeowners across Gainesville, Cumming, Dawsonville, Buford, and beyond properly integrate skylights without compromising roof integrity.

Here’s what you need to know before you cut into a metal roof.

Why Proper Skylight Integration Matters

Metal roofs, especially standing seam systems, are known for:

• Long lifespan (40–70+ years)

• Exceptional weather resistance

• Energy efficiency

But the moment you install a skylight without careful detailing, you introduce potential weak spots. Improper integration leads to:

• Water intrusion

• Condensation issues

• Fastener corrosion

• Voided warranties

Our team has repaired plenty of poorly installed skylights. We’d rather help you do it right the first time.

3 Key Components of a Leak-Free Skylight Installation

1. Curb-Mounted vs. Deck-Mounted Skylights

For metal roofing, curb-mounted skylights are usually best. Why?

• They elevate the skylight above the roof plane

• Allow for better flashing integration

• Reduce risk of water pooling

We build custom flashing around the curb to match your metal panel profile.

2. High-Temp Underlayment

We always use high-temperature ice and water shield under and around skylights. It’s essential under metal roofs, especially in Georgia's hot summers and humid storms.

3. Custom Flashing Integration

Factory flashing kits don’t always work with standing seam or corrugated panels. We fabricate custom flashing that:

• Follows your roof’s seam layout

• Diverts water away from the curb

• Prevents capillary action issues

Common Skylight Integration Mistakes (We Fix These Often)

• Using shingle-style flashing on a metal roof

• Fastening directly through panels without gaskets

• Relying solely on caulk instead of mechanical seals

• Ignoring thermal movement of the roof panels

If your roof expands but your skylight flashing doesn’t, you’re going to have problems.

Can Skylights Work on Low-Slope Metal Roofs?

Yes, but you need to be extra cautious.

On roofs below 3:12 pitch, we install:

• Raised curbs to elevate the skylight at least 4–6 inches

• Full perimeter membrane protection

• Redundant sealant barriers
