Sunroof tint is not regulated by state law
U.S. state tint laws regulate VLT on the windshield, front side windows, back side windows, and rear window. Sunroofs and moonroofs are not listed in any state statute because they are not part of the driver’s primary view and are not safety-glazing surfaces governed by FMVSS 205.
Practical result: you can tint a sunroof to any darkness (including 5%) in every U.S. state without violating any tint law.
Practical considerations
- Single pane of glass — easier to install than curved side windows.
- Solar exposure is intense — ceramic film at 5–20% VLT can reduce peak cabin temperature by 20°F on a hot day.
- Retractable roofs — the film must be durable enough to handle repeated retraction without scuffing.
- Panoramic glass (Tesla Model Y, Subaru Crosstrek, Hyundai Ioniq) — large single-piece installation preferred over seams.
Warranty & factory-installed sunroof film
Some premium vehicles ship with factory-installed UV-rejecting film on the panoramic roof. Adding additional aftermarket film on top is technically legal but may void the factory film warranty. Confirm with the manufacturer before installing.
Sunroof & moonroof window tint — FAQ
Is sunroof tint legal?
Yes, in every U.S. state. Sunroofs are not covered by state window tint statutes. You can apply 5% VLT to a sunroof without violating any tint law.
Should I tint my Tesla Model Y glass roof?
Yes if you live in a hot climate. Ceramic at 20% VLT on the roof can drop peak cabin temperature by 15–20°F on sunny days, which meaningfully extends EV range via reduced HVAC draw.
