Skylight Repair & Installation: Benefits, Costs, and Common Problems

A skylight can turn a dark, stuffy room into a place you want to spend all day. But when glass fogs up or rainwater drips onto your floor, that little window in the sky can quickly become a headache. At Mikku Roofing, we know the pressure to act fast, especially if your roof is leaking or your business can’t afford downtime.

Whether you’re a homeowner or run a busy commercial space, understanding skylight repair and installation helps you protect your property and your peace of mind. Let’s break it down together.

Skylight Types and Benefits ☀️

Let’s start at the top—literally. Not all skylights are created equal. Here’s what you’ll find out there:

• Fixed skylights: These don’t open. Think of them as permanent windows to the sky.
• Vented skylights: They open and close, letting in fresh air as well as sunlight—great for kitchens or bathrooms.
• Tubular skylights: Perfect for tight or windowless spaces—think hallways or closets—using a reflective tube to pipe in daylight.

Why Install a Skylight?

• Natural Light: Rooms feel bigger, brighter, and more welcoming. Sunlight can boost mood and productivity, whether you’re at home or working.
• Improved Ventilation: Vented models help remove stale air, moisture, and odors—key for healthy indoor air.
• Energy Savings: Rely less on artificial light and reduce heating costs with passive solar warmth.
• Property Value: Skylights are a selling point for both homes and commercial buildings.

Signs of Common Skylight Problems

Skylights look simple, but a lot can go wrong. Watch for these red flags:

• Leaks or Drips: Water stains, peeling paint, or puddles after rain. Sometimes it’s a flashing issue; sometimes it’s cracked glass.
• Condensation or Fogging: Cloudy glass or moisture between panes usually means the seal has failed.
• Drafts or Temperature Swings: If you feel a breeze, insulation around the skylight could be compromised.
• Discoloration or Mold: Dark, musty spots around the frame signal ongoing moisture problems.
• Cracked or Broken Glass: Obvious, but dangerous—especially in commercial spaces with foot traffic below.

These warning signs can start small and grow fast, especially after storms or heavy snow.

Quick Safety Checklist for Skylight Repairs 🛡️

Safety comes first—always. Roof work is risky, and glass can cut deeper than regret. Here’s what every homeowner or property manager should consider before touching a skylight:

• Wear slip-resistant shoes and a hard hat.
• Use a safety harness when working above ground.
• Don’t walk directly on glass or plastic skylight covers.
• Use a sturdy, properly placed ladder.
• Protect eyes and hands with goggles and gloves.
• Watch for overhead wires, especially on commercial roofs.

Refer to OSHA’s Construction Standards for detailed safety requirements.

DIY or Call a Pro?

Some repairs look easy—just a dab of caulk, right? But skylights are trickier than they seem. Here’s when you can try DIY, and when you should pick up the phone:

DIY Might Work If:

• You’re cleaning debris or leaves from around the frame.
• Replacing a simple gasket or applying a temporary sealant (for minor leaks).
• Clearing condensation vents.

Call a Pro When:

• Glass is cracked, foggy, or broken.
• You spot mold, stains, or recurring leaks.
• The frame or flashing looks warped or rusted.
• The skylight is on a steep, high, or flat roof—especially commercial properties.
• You need to match roofing, gutter repair near you, or integrate with other emergency roofing work.

Working with glass and roof penetrations isn’t just about skill—it’s about safety and knowing local code.

Inspection & Diagnosis

• Check the skylight, flashing, and surrounding roof for damage.

Prevention & Maintenance

A little care goes a long way. Here’s how to keep your skylight shining bright:

• Clean glass and frames twice a year.
• Clear leaves and debris from gutters and roof valleys around skylights.
• Inspect seals and flashing every spring and fall.
• Schedule a professional inspection after heavy storms or hail.
• Address gutter repair and roof maintenance near you to prevent water backup.

Staying ahead of issues turns big headaches into simple fixes.

Costs & Time Factors

How much? How long? Two questions everyone asks. While every job is unique, here’s what affects skylight repair and installation costs:

Repair Costs

• Minor fixes (sealant, gaskets): Lower end.
• Glass or frame replacement: Mid-to-upper range.
• Flashing or roof integration issues: Higher cost, especially if tied to emergency roofing.

Installation Costs

• Fixed skylights: More affordable, less labor.
• Vented or custom units: Higher price, more complex installation.
• Commercial installations: Larger scale means more investment.

Time factors: Simple repairs can take an hour or two. Full installations may take half a day to a couple days, depending on roof type and access.

Always ask about manufacturer warranties on new units and installation labor.

When It’s an Emergency 🚨

Some skylight problems can’t wait. Call for emergency roofing help if:

• Water is leaking during a storm.
• Broken glass is a safety hazard.
• There’s structural damage to the roof around the skylight.
• Commercial operations are at risk from leaks or glass.

Mikku Roofing responds fast, minimizing downtime and water intrusion.

FAQ

How long do skylights last?

Most modern skylights last 10–20 years with proper maintenance. Older units often fail sooner, especially if seals or flashing are neglected.

Can a leaking skylight be repaired, or does it need replacing?

Small leaks can often be fixed with new sealant or flashing. If glass is foggy, cracked, or the frame is warped, replacement is usually best.

Are skylights energy efficient?

Yes—modern skylights use double or triple glazing and insulated frames. Proper installation is key. Energy Star-certified skylights help regulate indoor temperatures.

What’s the safest way to clean a skylight?

Use a soft cloth, mild soap, and warm water. Never stand or lean on the glass. For hard-to-reach skylights, call a professional with proper equipment.

Local & Seasonal Considerations

Skylight problems often peak after storms, heavy snow, or high winds. In colder climates, ice dams can force water under flashing. In hot regions, UV can weaken seals and plastic domes. Schedule inspections before and after severe weather, and don’t forget about regular gutter cleaning—clogged gutters can send water straight toward your skylight.
