A skylight in tiled roof can develop a few common problems as the years go by. Leaks are usually the first thing homeowners notice. But there can also be drafts, foggy glass from trapped condensation, small cracks, or issues with the flashing around the frame. Tile roofs are built to move water safely down the roof. Each tile overlaps the next, guiding rain toward the gutters. But once a skylight is installed, that smooth flow of water gets interrupted a bit.

That’s where the flashing around skylight areas becomes really important. It acts like a small shield, pushing rainwater around the skylight instead of letting it sneak under the tiles. If that flashing gets worn out or wasn’t installed properly years ago water can slowly make its way inside. Skylights are pretty common in Southern California homes because they bring in so much natural light. Rooms feel brighter, more open.

Key Takeaways

• Most skylight leaks happen because of damaged flashing around skylight sections.

• Foggy skylight glass usually means the seal between panes has failed.

• Drafts often point to insulation or sealing issues.

• Skylights older than 15–20 years often need replacement.
  

Why Skylights in Tiled Roofs Often Develop Problems

A skylight in tiled roof is basically a window installed into the roof system. And roofs… well, they’re designed to keep water out.

Any time that system gets interrupted, things need to be sealed perfectly.

Tile Roof Design Is Different

Tile roofs aren’t flat. They’re layered.

Each tile overlaps the next one, forming small channels that guide rainwater down the roof. It’s actually a pretty smart system.

But installing a skylight means cutting into that pattern.

Contractors have to remove tiles, install flashing underneath, then rebuild the tile layout around the skylight frame. If the flashing isn’t aligned correctly or if sealant deteriorates over time water can sneak underneath the tiles.

Sometimes slowly. Sometimes during heavy storms.

Sun and Weather Take a Toll

Skylights get hit with a lot of sun. Especially here.

Heat during the day. Cooler temperatures at night. Rainstorms during winter. All of that expansion and contraction eventually wears down sealants and metal flashing.

That’s why roofers performing skylight installation Southern California usually emphasize proper flashing systems. It’s the most important defense against leaks.

Still, even well-installed skylights need occasional maintenance.

7 Common Skylight Problems and How To Fix Them

1. Skylight Leaks

This one shows up the most.

Water finds its way inside through worn sealant or damaged flashing around the skylight frame.

Why It Happens

Over time, the flashing around skylight areas can shift or corrode. Once rainwater slips under the tiles, gravity takes over. Water travels along the roof deck until it finds a path inside.

You might notice ceiling stains first.

Sometimes after a heavy storm.

How To Fix It

Roofers usually remove the surrounding tiles and inspect the flashing system. If flashing is damaged, it gets replaced.

Applying more sealant alone usually doesn’t fix the real problem.

2. Condensation Between Glass Panels

Most skylights today use double-pane glass.

The space between the glass panels contains insulating gas that helps regulate temperature.

What Goes Wrong

Eventually, the seal holding those panes together can fail. Once that happens, moisture gets trapped inside.

That’s when the skylight starts looking foggy.

Fix

Unfortunately, the glass unit usually needs replacement. Once the seal fails, there’s no simple repair.

3. Drafts Around the Skylight

You shouldn’t feel airflow around a skylight.

If you do, something isn’t sealed right.

Possible Causes

• insulation gaps around the frame

• deteriorated sealant

• damaged flashing around skylight areas

Fix

Roofers typically reseal the skylight frame and inspect the insulation surrounding the opening.

Sometimes minor adjustments fix it quickly.

4. Cracked Skylight Glass

Glass skylights can crack from temperature changes, falling debris, or simple material aging.

Even a small crack matters.

Water eventually finds it.

Fix

Glass replacement is usually required. Temporary patching rarely holds for long.

5. Damaged Flashing

Flashing is the protective barrier surrounding the skylight frame.

When flashing deteriorates, leaks usually follow.

Warning Signs

• water stains around skylight corners

• dripping during rainstorms

• gaps near roof tiles

Fix

Roofers remove surrounding tiles and install new flashing systems designed for tile roofs.

This step is extremely important during skylight installation Southern California, where tile roofing systems are very common.

6. Blocked Drainage Channels

Some skylights include tiny drainage channels built into the frame.

These channels move water away from the glass.

What Happens

Leaves, dust, or debris clog them.

Water starts pooling around the skylight frame.

Eventually it leaks inside.

Fix

Cleaning the drainage channels and resealing the skylight frame usually solves the issue.

7. Aging Skylights

Sometimes the skylight itself is simply reaching the end of its life.

Most skylights last around 15–20 years.

After that, small problems often start stacking up.

Sealants shrink. Flashing weakens. Glass insulation declines.

When Replacement Makes Sense

If repairs start happening repeatedly, replacing the skylight is often the better option.

New skylights are far more energy efficient anyway.

Skylight Services Homeowners Often Need

Not really a weekend DIY project.
