Skylights are one of those rare features that blend function and style — flooding your home with natural light, adding character, and creating a more open, inviting atmosphere. But like every other part of your roof, they need care and attention. Without proper upkeep, skylights can become a source of leaks, drafts, and water damage — especially in places like Washington, Chesterfield, and Eureka, where the weather is often unpredictable.
At RC Roofing, we’ve worked with homeowners all over Washington, Wildwood, and Town & Country who were surprised to find that a small skylight issue could turn into a much bigger roofing problem. That’s why we created this detailed guide on skylight repair — what it involves, when it’s needed, and how to keep your home safe, dry, and beautiful year-round.
Why Skylights Need Special Attention
While skylights are designed to be weather-tight and durable, they are still penetrations in your roofing system. That means they’re exposed to the same heat, cold, rain, wind, and shifting temperatures as your shingles — and sometimes more.
Over time, seals can degrade, flashing can warp, and the surrounding materials can shift due to settling or storm activity. A small leak around the skylight can lead to serious interior water damage if not caught early. For homeowners in areas like Frontenac or Augusta, where temperature swings are common, timely skylight repair can save thousands in future roof or drywall repairs.
Common Skylight Issues That Require Repair
The signs of skylight trouble aren’t always obvious. Many leaks don’t show up directly under the skylight. Instead, water might travel along rafters or ceiling beams before appearing in another part of the room.
Here are a few of the most common reasons we’re called for skylight repair:
Leaking Around the Skylight Frame
This usually happens when the flashing or seals around the skylight start to fail. It’s especially common in older skylights or those installed without proper underlayment.
Cracked or Fogged Glass
Thermal expansion or hailstorms can crack skylight panes. Fogging usually indicates that the seal between panes in double-glazed units has broken.
Roof Shingle Damage Around Skylights
Improper installation or aging can cause shingles to lift or fail near the skylight, letting moisture in.
Condensation and Moisture Buildup
Poor insulation or ventilation can cause skylights to collect moisture from inside the home, leading to mold or mildew around the frame.
Interior Water Stains or Ceiling Spots
If you notice discoloration on the ceiling near your skylight — or hear dripping after heavy rain — it’s time for a professional skylight repair assessment.
How Skylight Repairs Protect Your Roof
When left unaddressed, skylight issues can escalate from a minor nuisance to major structural damage. Repairing a small leak now can prevent:
- Rotting roof decking
- Damaged insulation
- Ceiling and drywall repairs
- Mold and mildew growth
- Costly full skylight replacements
Homeowners in Union, Pacific, and Wildwood often call us after seeing moisture stains months after the issue started. By that point, repairs are more involved — and more expensive. Acting early makes all the difference.
In short, skylight repair is not just about the window — it’s about protecting the entire roofing system around it.
The Skylight Repair Process
At RC Roofing, we follow a detailed process to ensure every skylight issue is handled correctly — and completely.
Step 1: Full Inspection
We start by inspecting both the interior and exterior. From the attic to the roofline, we check for signs of water intrusion, flashing issues, and material wear.
Step 2: Leak Source Identification
Not all leaks are from the skylight itself. We examine shingles, underlayment, and the skylight frame to find the exact origin of the issue before we begin any work.
Step 3: Targeted Repairs
Depending on the cause, skylight repair may include resealing, flashing replacement, shingle work, or full glass replacement. Our goal is to repair what’s needed and preserve what’s still functioning.
Step 4: Preventive Sealing and Flashing Work
After fixing the immediate issue, we often recommend resealing the surrounding areas and improving flashing — especially if the skylight is older or original to the home.
Step 5: Final Water Test
Once repairs are complete, we simulate rainfall to confirm the issue has been fully resolved.
Homeowners in Chesterfield and Town & Country appreciate that we don’t just patch things up — we solve the root problem so it doesn’t come back.
When a Repair Isn’t Enough
There are times when skylight repair may not be the best long-term solution — especially if your skylight is 20+ years old, or if it was installed with materials that are no longer performing.
You may want to consider replacement if:
- The frame is warped or cracked
- Glass panes have failed or fogged permanently
- Flashing is completely deteriorated
- Water damage is widespread
Replacing a skylight during a full roof replacement is also a smart move. If you live in Eureka or Washington and are already planning new shingles, now’s the time to update your skylight as well — before issues arise.
The Cost of Skylight Repairs
We understand budget matters. Most skylight repair costs depend on:
- The extent of the damage
- The type of skylight (fixed, vented, tubular, etc.)
- Access to the skylight (roof height, pitch, etc.)
- Roof condition surrounding the skylight
Smaller repairs — like resealing or flashing replacement — are often affordable and completed quickly. Larger structural issues or full replacements cost more, but help you avoid long-term moisture damage that’s much harder to repair.
We always provide a detailed quote and walk you through every option so you can decide what works best for your home.
Preventing Future Skylight Problems
Once your skylight is repaired, a few simple steps can help it stay in good shape for years:
- Clean skylight glass and trim twice a year
- Keep gutters and roof valleys clear
- Trim overhanging trees to reduce debris buildup
- Watch for signs of leaks during storms
- Schedule a roofing inspection every 1–2 years
Many homeowners in Frontenac and Union include skylight checks during their spring or fall maintenance — a small step that prevents surprise issues later on.
