How to Clean Skylights Safely (And Why You Shouldn't DIY It)

Skylights are one of the few window cleaning jobs where we'd actively discourage DIY, and it's not just liability talk.

Why Skylights Are Different

Unlike a ground-floor window, skylights combine height, awkward viewing angles, and often roof access. A ladder alone usually isn't enough — you need the right reach tools or actual roof access, and either comes with real fall risk if you're not equipped or experienced.

What Professional Skylight Cleaning Involves

• Extension poles or water-fed systems that reach the glass without needing to stand directly on the roof.
• Purified water systems that dry spot-free without wiping — useful since skylights are hard to towel-dry safely.
• An assessment of roof pitch and access before the job starts, not during it.

How Often They Need Cleaning

Skylights collect more debris than vertical windows since they're horizontal or angled — leaves, dust, and bird activity settle on them. Once or twice a year is typical, more if you're under trees.

The Bottom Line

Skylights are one of the clearest cases where the cost of hiring a pro is smaller than the risk of doing it yourself.
