7 Skylight Maintenance Tips

1. Keep Your Skylight Clean

Dirt, dust, and water spots can make your skylight look cloudy and block sunlight. Keeping it clean will help it stay clear and bright.

• Use a soft cloth or sponge with a mild soap and water solution.
• Avoid harsh cleaners or anything rough that could scratch the glass.
• If your skylight is hard to reach, use a long-handled cleaning tool or hire a professional skylight installation company.

Cleaning your skylights twice a year—in spring and fall—is a good rule of thumb.

2. Check for Leaks

A leaky skylight can cause water damage, mold, and high energy bills. Catching leaks early can save you a lot of money. Look for:

• Water stains or damp spots on the ceiling near the skylight.
• Dripping water during or after rain.
• Condensation inside the glass, which could mean a broken seal.

If you spot any of these issues, call a professional right away before the damage gets worse.

3. Inspect the Flashing and Seals

The flashing (the metal around the skylight) and sealant help keep water out. Over time, they can wear out due to sun exposure, rain, and temperature changes.

• Look for cracks, rust, or loose areas around the skylight.
• Make sure the sealant isn’t peeling or missing.
• If you see damage, get it repaired before leaks start.

Checking the flashing once a year can help prevent expensive water damage.

4. Trim Nearby Trees

If you have trees near your home, branches and leaves can be a problem. Strong winds and storms can break branches that scratch or crack the skylight glass.

• Trim any branches hanging over or near your skylight.
• Remove leaves, pine needles, or other debris that can pile up around it.

This simple step protects your skylight and prevents clogged gutters, which can lead to water pooling on your roof.

5. Control Moisture and Condensation

Sometimes, skylights trap humidity, leading to condensation inside the glass. This can cause mold and mildew over time.

• Use exhaust fans in rooms with skylights, like bathrooms and kitchens.
• Open windows every now and then to let fresh air in.
• If condensation is a regular problem, consider a vented skylight for better airflow.

Good ventilation keeps your skylight dry and damage-free. So make sure your skylight installation company can properly assess your home’s ventilation needs during installation. 

6. Protect Against Heavy Snow

Draper, Utah, gets a fair amount of snow in the winter, and too much snow on your skylight can be dangerous. Heavy snow adds weight and can cause cracks or leaks.

• Use a soft brush or roof rake to gently remove snow from around the skylight.
• Avoid hitting or scraping the glass, as this could cause damage.
• If your area gets a lot of snow, consider heated skylights to prevent buildup.

Taking care of your skylight before winter storms can help prevent costly damage.

7. Schedule Professional Inspections

Even if your skylight looks fine, it’s still a good idea to have a professional check it once a year. Experts can:

• Spot hidden cracks or leaks before they become big problems.
• Make sure the flashing and seals are in good shape.
• Recommend repairs or upgrades if needed.

A professional inspection can save you money in the long run by preventing major repairs. Plus, they can also give you more skylight maintenance tips tailored to your specific circumstances.
