How to Clean and Maintain Skylights Year-Round

Skylights brighten up a room like nothing else. But dirt, leaks, or foggy glass can dim that natural light fast. If you’ve ever noticed water spots, condensation, or even a draft under your skylight, you know how quickly minor issues can turn into bigger headaches.

At Shindo Trust Roofing, we believe a clean, well-maintained skylight is more than just a pretty feature—it’s a key part of your roof’s health and your comfort. Regular attention keeps your view clear and helps you spot problems before they grow. Let’s break down how to care for skylights year-round, with safe steps and practical tips for every season.

Cleaning Steps: Tools and Techniques for Every Skylight Type 🧽

First things first: safety. Never climb onto a roof or attempt to clean exterior glass unless you know the surface is dry and stable. Always follow OSHA guidelines and use a sturdy, properly placed ladder. If you’re at all unsure, call a professional.

What you’ll need:

• Soft microfiber cloths or non-abrasive sponges
• Telescoping pole (for hard-to-reach glass)
• Mild dish soap
• Bucket of lukewarm water (never hot, which can crack glass)
• Squeegee
• Soft-bristle brush for frames
• Safety gloves and shoes with good grip

For glass skylights:

1. Dust the interior frame and glass gently to remove cobwebs.
2. Mix a few drops of dish soap in water. Wipe the glass in circles, working from top down.
3. Rinse with clean water and squeegee dry to keep streaks away.
4. Clean frames with a damp cloth. Avoid harsh chemicals or scrubbing pads.

For plastic or acrylic skylights:

• Use only mild soap and water. Chemicals can cloud or scratch the surface.
• Never use ammonia-based products, as they damage plastic over time.

For vented or opening skylights:

• Clean tracks and hinges with a dry brush. Check that moving parts are free of debris.

Be gentle—think of cleaning a camera lens, not scrubbing a kitchen floor. Too much pressure or the wrong cleaner can do more harm than good.

Inspecting for Leaks: What to Look For

A skylight leak isn’t always a dramatic drip. Sometimes it’s a faint stain, a bubble in the paint, or even a musty smell. Early signs are subtle, but catching them now can prevent expensive repairs later.

Key areas to inspect:

• Glass and frame: Look for cracks, fogging between panes, or chipped seals.
• Flashings: Examine the metal around the skylight for bends, rust, or gaps.
• Ceiling and drywall: Check for yellow spots, peeling paint, or dampness below the skylight.
• Sealant: Inspect the caulking where the skylight meets the roof. Shrinkage or cracks are red flags.

Use a flashlight on cloudy days to spot moisture or shadows that signal trouble. If you find anything suspicious, especially after storms or heavy snow, it’s wise to schedule a professional skylight inspection and repair.

Maintenance Schedule: Stay Ahead of Problems

Routine is your friend here. Skylights, like the rest of your roof, thrive on regular attention. Set a calendar reminder for these steps:

Spring:

• Clean glass and frames after winter weather.
• Check for leaks, especially if you’ve had ice dams or heavy snow.
• Inspect flashing and roof shingles nearby.

Summer:

• Remove pollen, dust, and bird droppings before they bake on.
• Lubricate hinges and check vented skylights for smooth operation.

Fall:

• Clear leaves, twigs, and other debris from around the skylight.
• Inspect for cracks or issues before cold weather arrives.

Winter:

• Safely clear snow buildup with a roof rake if you can reach from the ground.
• Watch for condensation or “sweating” inside, which can signal insulation issues.

A consistent maintenance schedule prevents problems from sneaking up on you—and keeps that sunlight beaming in.

Common Mistakes to Avoid

Some cleaning shortcuts do more harm than good. Don’t fall into these traps:

• Skipping safety: Balancing on a roof can be risky. Never rush or overreach.
• Harsh cleaners: Bleach, ammonia, or abrasive pads can scratch or weaken skylight surfaces.
• Ignoring minor leaks: Even a small drip can lead to mold and structural issues.
• Forgetting the flashing: The metal around your skylight is just as important as the glass.
• Using high-pressure washers: Too much force can break seals or force water inside.

Patience and the right tools beat shortcuts every time.

When to Call a Pro: Beyond the Basics 🚨

Some skylight issues are best left to those with the right training and equipment. If you notice:

• Persistent leaks, even after cleaning
• Cracked or fogged glass
• Water stains spreading across the ceiling
• Drafts or sudden temperature swings under the skylight

It’s time to call in a roofing professional. Complex repairs—like resealing flashing, replacing panes, or correcting installation errors—require careful work and can affect your roof’s warranty or insurance.

Safe Practices: Protect Yourself and Your Roof

Never risk your safety for a clean skylight. If you need to work near the edge or on a steep roof, use a harness, and have a spotter nearby. Always check weather conditions—wet roofs are slippery, and gusty winds can make ladders unstable.

Consult resources like the National Roofing Contractors Association (NRCA) or OSHA for up-to-date safety and maintenance recommendations. Roof maintenance isn’t just about clean glass; it’s about protecting your investment and your family.

Signs It’s Time for a Replacement

Not every problem can be wiped away. Watch for these signs that your skylight may need more than a cleaning:

• Repeated condensation inside the glass
• Cloudy or discolored panes that don’t clear up
• Crumbling or missing flashing
• Persistent leaks that return season after season

If you’re considering an upgrade to a more energy-efficient model, or you need a new installation, professional guidance is essential. You can learn more about safe installation and repair with our skylight-repair service.

Seasonal Considerations: Adjust for the Weather

Skylight care changes with the seasons. During spring and summer, pollen and dust are your biggest foes. In fall, debris and leaves can clog gutters and collect around skylight frames, trapping moisture. Winter brings snow and ice—never try to chip ice off your skylight, as you could crack the frame or glass.

Plan your cleaning and inspection routines to match the season, and always check the weather before heading up.

DIY or Professional? Know Your Limits

Some tasks—like gentle cleaning or basic inspection—are safe for handy homeowners. But if you spot anything that feels unsafe or beyond your skillset, don’t hesitate to call for backup. Skylights are integrated with your roof, insulation, and weatherproofing. One misstep can lead to leaks or void a warranty.

If you’re unsure, a quick call to a reputable roofing contractor can save time and money in the long run.

Frequently Asked Questions

How often should I clean my skylight?
Twice a year is a good rule—once in spring, once in fall. Extra cleanings may be needed if you live near trees or in a dusty area.

What if my skylight is foggy inside?
Condensation between glass panes usually means the seal is broken. This often requires professional repair or replacement.

Are all skylights cleaned the same way?
No. Always check the manufacturer’s instructions for your skylight type—glass, acrylic, vented, or fixed. When in doubt, use the gentlest method possible.

Can I prevent leaks by adding more caulk?
Not recommended. Over-caulking can trap moisture and hide bigger problems. Leaks often indicate an issue with flashing or installation.

Prevention: The Best Approach

Like any part of your home’s exterior, prevention is worth every minute. Clean glass lets in more light, and routine checks catch issues before they spread. Combine gentle cleaning with regular inspections, and your skylight will stay bright and trouble-free for years.
