Skylight Leak Repair Cost in Oregon

Half the "skylight leaks" in a wet climate are not the glass. They are the flashing kit around a hole in the roof, or condensation on a cold pane that never came from outside. Paying for a new unit when the curb flashing is the failure, or resealing a 25-year-old fogged dome, are how Oregon homeowners buy the same stain twice.

Three different bills, because there are three different failures

Condensation. Drips on cold mornings with no storm, fog that clears, moisture at the interior shaft. The skylight did not open. Bath vents, attic airflow, and an uninsulated shaft did. Fixing that can be ventilation and insulation work, not a roof opening. Cost is often a few hundred dollars if the unit is sound, and $0 in skylight parts.

Flashing and curb. Stains during wind-driven rain, wetness at the interior corners of the opening, moss against the uphill head. The covering around the unit is the leak. A roof-side rebuild (lift shingles, replace step, head, and apron pieces, tie in underlayment) typically runs $300 to $1,200 in 2026 national ranges, and sits in the same band as other Oregon flashing jobs. Curb rot pushes it to $800 to $1,800 because the box under the unit has to be rebuilt.

The unit itself. Fog between panes that never clears, cracked glazing, a frame that has moved, parts that are no longer made. Reflashing a dead skylight is a delay. Installed replacement for a standard residential unit commonly lands $1,200 to $3,500, and more when the shaft, drywall, or a custom size is involved.

A tube of sealant on the interior glass does not belong on any of those invoices as the permanent fix.

How to tell which bill you are about to get

Pattern first, then age.

• Only on cold, dry nights: start with condensation
• Only in hard wind-driven rain: flashing or head detail
• Any rain, any wind, plus fogged glass: the unit is in play
• Unit under about 15 years, glass clear, leak at the frame: flashing is the cheaper first inspection
• Unit over 20 years, or you are already tearing off the roof: replacement during the reroof is usually cleaner than opening new shingles later

Oregon freeze-thaw is milder than the Midwest, but the rain season is longer. Head flashing that is short, and valleys that dump onto a skylight, fail here more often than ice dams. If the leak is also at a nearby chimney or wall, read roof flashing problems in Oregon before you assume the pane is guilty.

What a skylight repair visit should include

The skylight repair scope should say whether the unit stays. If it stays, the work is a flashing kit matched to the roof material, underlayment around the curb, and shingles woven back in. If it goes, the visit includes curb inspection, a factory flashing kit for the new unit, and interior finishes as a separate line so you are not surprised by drywall.

West-side houses in Aloha pick up the same fir-needle debris against skylight heads that Portland does. Call Roof Repairs Pro at (503) 317-8312 with the unit's approximate age, whether the glass is fogged, and whether the drip happens in dry cold or only in storms.
