Why is my skylight leaking in Aberdeen

Your skylight is leaking in Aberdeen because the seal between the glass and the curb has failed, the flashing around the curb has pulled loose, or wind-driven rain is being forced sideways past a gasket that was never rated for 40 mph gusts off Grays Harbor. In roughly seven out of ten skylight leaks we inspect here, the glass itself is fine - the water is getting in at the perimeter. This post walks through the specific causes we see in Aberdeen, how to tell a skylight leak from a general roof leak, what a real fix looks like, and when it is time to hand it to a professional.

Why is my skylight leaking in Aberdeen WA?

A skylight leaking in Aberdeen WA is almost always a perimeter failure, not a glass failure. The unit sits on a raised wooden curb, and that curb has four sides of flashing, two layers of sealant, and a gasket where the glass clamps into the frame. Any one of those five points can let water through.

Skylight leak detection in Aberdeen WA starts with understanding what this climate does to a roof. We get around 75 inches of rain a year, most of it between October and April. That is not a drizzle - it is horizontal, wind-driven rain pushed by Pacific storms. Water does not fall on your skylight in Aberdeen. It attacks it from the side.

Here is the definitional version: a skylight leak is water intrusion at the frame, curb, or flashing of a roof window, and it is typically caused by failed sealant, cracked gaskets, or corroded flashing rather than by broken glass.

Most of the skylights we open up in Aberdeen are 12 to 25 years old. The original butyl or silicone sealant has dried, shrunk, and pulled away from the curb. The aluminum flashing has started to pit from salt air. The rubber gasket around the glass has gone hard. None of that is visible from the ground, which is why so many homeowners assume the whole unit needs replacing when it does not.

The Aberdeen-specific reasons skylights fail

Aberdeen skylights fail faster than skylights in drier parts of Washington for three reasons: rain volume, wind direction, and the age of the housing stock. If you own a home built before 1980 - and a lot of Aberdeen homes were - your skylight may be on its second or third round of sealant.

Wind-driven rain and sideways water

Standard skylight flashing is designed for water running down and off. Aberdeen rain does not cooperate. When a storm comes in off the harbor, water is driven against the uphill side of the curb at an angle. Any gap in the counter-flashing - even a hairline one - becomes an entry point.

We see this most on skylights facing south or southwest, which is the direction most of our winter storms track. A skylight that has been dry all summer will start dripping within the first week of heavy fall rain.

Failed sealant and hardened gaskets

Silicone sealant has a service life of about 5 to 10 years in this climate. After that it shrinks, cracks, and loses adhesion. The gasket that seals the glass to the frame has a similar lifespan. When it hardens, it stops compressing against the glass and water slips past.

This is the single most common cause of a slow drip during rain. The good news: resealing and re-gasketing are inexpensive compared to replacement.

Flashing that has pulled loose or corroded

Skylight flashing is usually aluminum or galvanized steel. Salt air off Grays Harbor accelerates corrosion. Once the metal pits through or the fasteners rust out, the flashing lifts and water gets behind it. This is the leak that shows up as a stain on the ceiling a foot or two away from the skylight, not directly under it.

If you are also seeing water at other roof penetrations, it is worth having the whole roof checked - our roof leak detection Aberdeen WA service maps every entry point in one visit.

Condensation, not a leak

Not every drip is a leak. A single-pane or older double-pane skylight can condense moisture on the interior glass when the inside air is warm and humid and the outside is 38 degrees. That water runs down the frame and looks exactly like a leak.

The tell: condensation shows up on cold mornings and stops when the interior humidity drops. A real leak tracks with rain.

How to tell a skylight leak from a roof leak

A skylight leak and a roof leak look identical from inside your house - both show up as a ceiling stain or a drip. The difference is where the water is entering, and that changes what the repair costs.

Here is how we sort it out on a first visit:

• Directly under the skylight: almost always the skylight itself - gasket, sealant, or glass seal.
• One to three feet away, usually downhill: flashing or curb failure. Water is getting in at the skylight and traveling along a rafter before it drops.
• At a ceiling joint or wall corner: often a roof leak that has nothing to do with the skylight, especially if you also have missing shingles or a clogged valley.
• Only during wind-driven rain: a perimeter seal issue, not a hole in the roof.
• Only on cold mornings: condensation.

If you want a definitive answer, a professional roof leak inspection Aberdeen WA with a moisture meter and a hose test will tell you in under an hour. We charge a diagnostic fee for that visit, and we credit it toward the repair if you hire us.

How to fix a skylight leak in Aberdeen, Washington

How to fix a skylight leak in Aberdeen, Washington depends entirely on where the water is entering. The repair is usually one of four jobs, and only one of them involves replacing the skylight.

1. Reseal the perimeter

If the leak is at the curb-to-roof joint or the glass-to-frame joint, we remove the old sealant, clean the surface, and apply a fresh bead of high-grade polyurethane sealant rated for exterior use. This is the cheapest fix - typically $250 to $500 in 2026 pricing for a single skylight, including the trip.

2. Replace the gasket

When the gasket around the glass has gone hard, resealing alone will not hold. We pull the glass, replace the gasket, reset the glass, and reseal. Expect $350 to $650 depending on the skylight size and how accessible the roof is.

3. Rebuild the flashing

Corroded or lifted flashing has to come off. We fabricate new counter-flashing and step flashing, set it in sealant, and fasten it properly. This is the fix that stops the leaks that show up a foot or two away from the skylight. Budget $600 to $1,200 for a full flashing rebuild on a standard curb-mounted unit.

4. Replace the skylight

If the frame is cracked, the glass seal has failed internally, or the unit is more than 25 years old and already on its third repair, replacement is the better money. A new skylight installed runs $1,400 to $3,000 depending on size and whether we are changing the curb.

If your skylight sits above a flat roof section - common on Aberdeen additions and porches - the repair may overlap with flat roof leak repair Aberdeen WA, since the membrane and the skylight curb share the same water path.

And if the leak has already stained drywall, bubbled paint, or soaked insulation, the repair does not stop at the roof. We handle the interior side too through our ceiling leak repair Aberdeen WA service so you are not left chasing two contractors.

Common mistakes we see homeowners make

The most expensive skylight mistake we see in Aberdeen is sealing over a problem instead of finding it. A tube of caulk from the hardware store will stop a drip for one season and hide the real failure for another year - by which time the decking underneath has started to rot.

Other mistakes worth avoiding:

• Caulking the glass instead of the frame. Sealant belongs at the perimeter joints, not smeared across the glass-to-frame line where it traps water.
• Ignoring a slow drip. A drip that fills a cup a day is still 90 gallons a year going into your ceiling assembly.
• Assuming the skylight is the problem. Roughly a third of the "skylight leaks" we get called out for turn out to be flashing or roof leaks nearby.
• Hiring the cheapest quote without a leak test. If a contractor does not hose-test the repair before leaving, you will not know it worked until the next storm.
• Waiting until spring. Aberdeen rain runs through April. A leak that starts in October has six months to do damage before the dry season.

If you are dealing with a leak that started during a storm and water is actively coming in, that is an emergency roof leak repair Aberdeen WA situation - we can tarp and stabilize the same day.

When to call a professional

Call a professional the moment your skylight leak shows up as a ceiling stain, a bulging paint bubble, or water running down a wall. Those are signs the leak has been active long enough to reach the interior, and the repair cost climbs fast from there.

You should also call us if:

• The leak returns within a year of a DIY reseal.
• You cannot see the skylight from a safe position on the roof.
• The flashing is visibly lifted, rusted, or missing fasteners.
• Your roof pitch is steep, or the skylight sits above a second story.
• You are seeing water in more than one spot.

Frequently Asked Questions

Why is my skylight leaking in Aberdeen WA?

In Aberdeen, skylights leak because wind-driven rain forces water past failed perimeter sealant, hardened gaskets, or corroded flashing. The glass itself is rarely the cause. Our 75 inches of annual rain and salt air off Grays Harbor accelerate sealant and metal failure well before the skylight reaches the end of its life.

Find the entry point first, then match the fix: reseal the perimeter for $250-$500, replace the gasket for $350-$650, rebuild the flashing for $600-$1,200, or replace the unit for $1,400-$3,000. Hose-test the repair before calling it done. Most Aberdeen skylight leaks are fixed without replacement.
